APPENDIX A-1
 

The following sections provide the methodology and rationale followed for the selection or development of 

compound-specific parameter values recommended by U.S. EPA OSW. Compound-specific values are 

provided for (1) physical and chemical properties, (2) fate-and-transport parameters, and (3) health 

benchmarks. A summary table of all compound-specific parameter values is provided at the end of this 

appendix, followed by individual parameter-value tables for each compound. The individual 

parameter-value tables cite sources for each parameter value. 

A.1.1 COMPOUND NAME with CHEMICAL ABSTRACTS SERVICE (CAS) NUMBER 

The Appendix A-1 Tables of waste constituents included in the Delisting Risk Assessment Software 

(DRAS) program are lists the chemicals by most common compound name. The CAS number provided in 

parenthesis is a unique number assigned to each compound in the table. 

A.1.2 PHYSICAL AND CHEMICAL PROPERTIES 

Molecular Weight (MW) 

Molecular weight (MW) of a compound is defined as the sum of atomic weights of all atoms in the 

compound’s molecule. 

Organics and Metals For most organics (except PCDDs and PCDFs) and metals, MW values were 

obtained from the following: 

C Budavari, S., M.J. O’Neil, A. Smith, and P.E. Heckelman. 1989. The Merck Index: An 

Encyclopedia of Chemicals, Drugs, and Biologicals. 11th Edition. Merck and Company, 

Inc. Rahway, New Jersey. 

MW values not provided in Budavari, O’Neil, Smith, and Heckelman (1989) were obtained from the 

following document: 

C	 Montgomery, J.H., and L.M. Welkom. 1991. Groundwater Chemicals Desk Reference. 

Lewis Publishers. Chelsea, Michigan. 

Because Budavari, O’Neil, Smith, and Heckelman (1989) provides MW values for most of the compounds 

evaluated, it was used as the primary source to ensure consistency. MW values are based on the 

compound’s formula; and, the values in Budavari, O’Neil, Smith, and Heckelman (1989) are the same as 

the values cited in several literature sources. MW values for most of the compounds in the primary 

guidance documents were also obtained from Budavari, O’Neil, Smith, and Heckelman (1989). 

PCDDs and PCDFs MW values for PCDDs and PCDFs were obtained from U.S. EPA (1994a). 

Mercuric Compounds MW values for mercury and mercuric chloride were obtained from Budavari and 

others (1989). MW value for methyl mercury was obtained from U.S. EPA (1997g).

Appendix A-1 October 2008 

Melting Point Temperature (T m )

Melting point temperature (T ) is the temperature of the compound (in degree Kelvin [K]) at which the 

solid state of the compound undergoes a phase change to a liquid phase. At ambient temperatures and at an 

atmospheric pressure of 1 atmosphere, compounds are either in a solid or liquid state. 

m 

Organics and Metals For most organics (except PCDDs and PCDFs) and metals, values for Tm were 

obtained from Budavari, O’Neil, Smith, and Heckelman (1989). T values not provided in Budavari, 

O’Neil, Smith, and Heckelman (1989) were obtained from Montgomery and Welkolm (1991). 

m 

Because Budavari, O’Neil, Smith, and Heckelman (1989) provides T values for most of the compounds 

evaluated, it was used as the primary source to ensure consistency. Tm values in Budavari, O’Neil, Smith, 

and Heckelman (1989) were generally within 2 to 3 degrees of the values provided in literature sources 

reviewed. Tm values for most compounds in the primary guidance documents were also obtained from 

Budavari, O’Neil, Smith, and Heckelman (1989). 

m 

PCDDs and PCDFs Tm values for PCDDs and PCDFs were obtained from U.S. EPA (1994a). 

U.S. EPA (1994a) provides T values for PCDDs and PCDFs, that were obtained from various literature 

sources. 

m 

Vapor Pressure (Vp) and Aqueous Solubility (S) 

The vapor pressure (Vp) of a substance is defined as the pressure in atmospheres exerted by the vapor (gas) 

of a compound when it is under equilibrium conditions. It provides a semi-quantitative rate at which it will 

volatilize from soil and/or water. The aqueous solubility (S) of a compound is defined as the saturated 

concentration of the compound in water (mg chemical/L water) at a given temperature and pressure, 

usually at soil/water temperatures and atmospheric pressure (Montgomery and Welkom 1991). 

Organics For most organics (except PCDDs and PCDFs), values for Vp and S were obtained from the 

following: 

C	 U.S. EPA 1994b. Draft Report Chemical Properties for Soil Screening Levels. Prepared 

for the Office of Emergency and Remedial Response. Washington, DC. July 26. 

U.S. EPA (1994b) provides measured, calculated, and estimated values for Vp and S that were obtained 

from various literature sources. Vp values in U.S. EPA (1994b) were generally either measured (at 20EC 

to 25EC) or calculated values obtained from various literature sources. U.S. EPA (1994b), however, E provides values for Vp corrected to 25 C. U.S. EPA (1995a) states that, because the distribution of many 

of the parameters is skewed, the geometric mean or the median values were preferable to the arithmetic 

mean values. Therefore, when available geometric mean values were preferred over the arithmetic mean 

values. 

E E In U.S. EPA (1994b), S values were either measured (at 20 C to 30 C) or calculated values obtained from E E various literature sources. Although S values were measured at temperatures ranging from 20 C to 30 C, E U.S. EPA (1994b) states that S values were not corrected to 25 C, because the variability in solubilities E E measured at 20 C to 25 C was within the overall range of measured values.

U.S. EPA (1994b) is the preferred source, because (1) sources and the conditions at which each value was 

obtained are provided, and (2) values were provided to 2 significant figures. Also, U.S. EPA (1994b) 

A-1-2 
 

RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

provides multiple Vp and S values for each compound from several different literature sources; providing a 

recent, more comprehensive compilation of reported literature values. Vp and S values from U.S. EPA 

(1994b) were generally consistent with those provided in U.S. EPA (1994e) and U.S. EPA (1995a). 

When Vp and S values were not available in U.S. EPA (1994b), they were obtained from one of three 

sources, in the following order of preference: 

1.	 U.S. EPA (1994e) 

2.	 U.S. EPA (1995a); values from which were obtained from one of three sources:

Physical-Chemical Properties and Environmental fate for Organic Chemicals.

3.	 U.S. EPA. 1994f. Superfund Chemical Data Matrix (SCDM). Office of Emergency and 

Remedial Response. Washington, DC. June. 

Vp and S values in U.S. EPA (1994e) were geometric mean values obtained from various literature sources. 

References specific to sources of values for each compound were provided in U.S. EPA (1994e) and were, 

therefore, preferred over U.S. EPA (1995a) values. 

Most Vp and S values in U.S. EPA (1995a) were obtained from Mackay, Shiu, and Ma (1992) or Howard 

(1989-1993). Mackay, Shiu, and Ma (1992) and Howard (1989-1993) obtain the “best” values after 

evaluation of various literature sources. 

Vp values in U.S. EPA (1994f) were obtained from various literature sources. S values in U.S. EPA 

(1994f) were the geometric mean of values obtained from various literature sources. 

Mercuric Compounds Mercury is a relatively volatile compound. Vp and S values for elemental mercury 

were obtained from Budavari, O’Neil, Smith, and Heckelman (1989). Vp and S values for methyl mercury 

were not found in the literature.

Henry’s Law Constant (H) 

Henry’s Law constant (H) is also referred to as the air-water partition coefficient, and is defined as the 

ratio of the partial pressure of a compound in air to the concentration of the compound in water at a given 

temperature under equilibrium conditions. Henry’s Law constant values generally can be (1) calculated 

from the theoretical equation defining the constant, (2) measured, or (3) estimated from the compound 

structure. Experimental and estimated H values from literature reports, however, are (1) very 

temperature-dependent and difficult to measure, (2) generally obtained from various literature sources that 

use different experimental and estimation methods, and (3) available for only a limited number of 

compounds. 

Organics For organics (excluding PCDDs and PCDFs), H values were calculated from the following 

theoretical equation (Lyman, Reehl, and Rosenblast 1982) for consistency, using recommended MW, S, and 

Vp values: 

Equation A1-1 

3 H = Henry’s Law constant (atm-m /mole)


Vp = Vapor pressure of Chemical (atm)
 

S = Solubility of Chemical in water (mg Chemical/L water)
 

The primary guidance documents also used theoretical Equation A-1-1 to calculate H values. 

PCDDs and PCDFs H values for PCDDs and PCDFs are calculated values obtained from U.S. EPA 

(1994a). 

Metals For all metals (except mercury), H is zero, because Vp—because of the nonvolatile nature of the 

metals—and S are assumed to be zero. 

Mercuric Compounds H values for elemental mercury, and methyl mercury were obtained from U.S. EPA 

(1997g). 

Diffusivity of Chemicals in Air (D ) and Water (D ) a w 

Diffusivity or diffusion coefficients in air (D ) and water (D ) are used to calculate the liquid or gas phase 

transfer of a Chemical into a water body. 

a w 

Organics For organics (except PCDDs and PCDFs), diffusivity values were obtained directly from the 

CHEMDAT8 model chemical properties database (Worksheet DATATWO.WK1):

CHEMDAT8 Air Emissions Program. Prepared for Chemicals and Petroleum Branch, 

OAQPS. Research Triangle Park. North Carolina. November 18. 

The U.S. EPA (1994c) database uses empirical correlations with compound density and molecular weight 

to calculate diffusivity values. For compounds not in the U.S. EPA (1994c) database, diffusivity values 

were obtained by using the WATER8 model correlation equations for air and water diffusivities: 

A-1-4

Appendix A-1 October 2008 

C U.S. EPA. 1995d. WATER8—Air Emissions Models Wastewater Treatment. 

Version 4.0. OAQPS. Research Triangle Park. North Carolina. May 1. 

U.S. EPA (1995c) database values were predicted by using chemical-structural relationships. Diffusivity 

values for all compounds in the U.S. EPA (1994c) and (1995c) databases were either predicted or 

estimated. The primary guidance documents also recommended U.S. EPA (1994c) and (1995c) database 

model values. More recent documents, including the following, also recommended these values: 

C U.S. EPA. 1996. Soil Screening Guidance: Technical Background Document and 

User’s Guide. Office of Solid Waste and Emergency Response. Washington, DC. 

EPA/540/R-95/128. May. 

For diffusivity values that were not available in these databases, D and D values were calculated using 

the following equations cited and recommended for use in U.S. EPA (1997g): 

w a 

Equation A1-2a 

Equation A1-2b 

U.S. EPA (1995a) recommended the use of standard default diffusivity values. U.S. EPA (1995a) stated 

that the diffusivity parameters vary slightly, and default values appear to be within the range of typical 2 values. Values for diffusivity in air range from about 0.01 to 0.1 square centimeters per second (cm /s); 2 therefore, U.S. EPA (1995a) recommended a default value of 0.08 cm /s. Values for diffusivity in water -06 -05 2 range from 1 x 10 to 1 x 10 cm /s; therefore, U.S. EPA (1995a) recommended a default value of -06 2 8 x 10 cm /s. Diffusivity values calculated using Equations A-1-2a and A-1-2b were within the range 

specified by U.S. EPA (1995a). 

PCDDs and PCDFs Diffusivity values in air and water for (1) 2,3,7,8-TCDD were obtained from 

U.S. EPA (1994c). 

Metals and Mercuric compounds For metals (except chromium and mercury), diffusivity values were not 

available in the literature. Diffusivity values for chromium and mercury were obtained from the U.S. EPA 

(1994c) database. The diffusivity value for methyl mercury was calculated using Equations A-1-2a and 

A-1-2b.

Soil Organic Carbon-Water Partition Coefficient (K ) oc 

The soil organic carbon-water partition coefficient (K ) or the organic carbon normalized soil sorption 

coefficient is defined as the ratio of adsorbed compound per unit weight of organic carbon to the aqueous 

solute concentration (Montgomery and Welkom 1991). 

oc 

Organics Because of the soil mechanisms that are inherently involved, K values for the ionizing organics 

and nonionizing organics are discussed separately. 

oc 

Ionizing Organic Compounds 

Ionizing organic compounds include amines, carboxylic acids, and phenols. These compounds contain the 

functional groups that ionize under specific pH conditions, and include the following: 

oc 

C Organic acids (2,4,6-trichlorophenol; pentachlorophenol; 2,3,4,5-tetrachlorophenol; 

2,3,4,6-tetrachlorophenol; 2,4,5-trichlorophenol; 2,4-dichlorophenol; 2-chlorophenol; 

phenol; 2,4-dimethylphenol; 2-methylphenol; 2,4-dinitrophenol; and benzoic acid) 

C Organic bases—n-nitroso-di-n-propylamine; n-nitrosodiphenylamine, and 4-chloroaniline) 

K values for ionizing organic compounds were obtained from U.S. EPA (1994b). U.S. EPA (1994b) 

provides K values for the ionizing organic compounds that have been estimated on the basis of the degree 

of ionization and the relative proportions of neutral and ionized species. The primary guidance documents 

cite one value for the ionizing organics, independent of the pH. The primary guidance documents calculate 

oc 

K values for the ionizing organics by using correlation equations containing K that are applicable to oc ow 

nonionizing organics. However, K values for ionizing compounds can vary vastly, depending on the pH oc 

conditions in the environment. For the ionizing organic compounds, the estimated K values based on pH 

are provided. 

oc 

K values were estimated on the basis of the assumption that the sorption of ionizing organic compounds is 

similar to hydrophobic organic sorption, because the soil organic carbon is the dominant sorbent. 

According to U.S. EPA (1994b), for low pH conditions, these estimated values may over predict sorption 

coefficients, because they ignore sorption to components other than organic carbon. 

oc 

Nonionizing Organic Compounds 

Nonionizing organic compounds are all other organic compounds not listed earlier as ionizing. They 

include volatile organics, chlorinated pesticides, polynuclear aromatic hydrocarbons (PAHs), and 

phthalates. The geometric mean of measured K values are provided in the following document: oc 

C U.S. EPA. 1996a. Soil Screening Guidance: Technical Background Document and 

User’s Guide. Office of Solid Waste and Emergency Response. Washington, DC. 

EPA/540/R-95/128. May. 

U.S. EPA (1996a) calculated the geometric mean value from various measured values. For compounds for 

which K values are not provided by U.S. EPA (1996a), K values were calculated using K correlation 

equations provided in the same document.

Metals For metals, no K values were found in the literature. For metals, soil/sediment-water partitioning 

coefficients (Kd) were obtained directly from experimental measurements. 

oc 

Chemical Partitioning, Partitioning Coefficients for Soil-Water (Kd ) and Suspended s 

Sediment-Surface Water (Kd ) sw 

Partition coefficients (Kd) describe the partitioning of a compound between sorbing material, such as soil, 

soil pore-water, surface water, suspended solids, and bed sediments. For organic compounds, Kd has been 

estimated to be a function of the organic-carbon partition coefficient and the fraction of organic carbon in 

the partitioning media. For metals, Kd is assumed to be independent of the organic carbon in the 

partitioning media and, therefore, partitioning is similar in all sorbing media. 

The soil-water partition coefficient (Kd ) describes the partitioning of a compound between soil pore-water 

and soil particles, and strongly influences the release and movement of a compound into the subsurface 

s 

soils and underlying aquifer. The suspended sediment-surface water partition coefficient (Kd ) coefficient 

describes the partitioning of a compound between surface water and suspended solids or sediments. 

sw 

Organics For organics (including PCDDs and PCDFs), soil organic carbon is assumed to be the dominant 

sorbing component in soils and sediments. Therefore, Kd values were calculated using the following 

fraction organic carbon (fOC) correlation equations: 

Equation A-1-3a 

Equation A-1-3b 

U.S. EPA. 1993. Review Draft Addendum to the Methodology for Assessing Health Risks 

Associated with Indirect Exposure to Combustor Emissions. Office of Health and Environmental 

Assessment. Office of Research and Development. EPA-600-AP-93-003. November 10. 

U.S. EPA (1993d), from literature searches, states that fOC could range as follows: 

C 0.002 to 0.024 in soils—for which a mid-range value of foc,s = 0.01 generally can be used. 

C 0.05 to 0.1 in suspended sediments—for which a mid-range value of f = 0.075 

generally can be used. 

oc,sw 

The DRAS uses mid-range f values recommended by U.S. EPA (1993). Kd values were calculated using oc 

K values recommended for each compound. oc 

Metals For metals (except mercury), Kd is governed by factors other than organic carbon, such as pH, 

redox, iron content, cation exchange capacity, and ion-chemistry. Therefore, Kd values for metals cannot 

be calculated using the same correlation equations specified for organic compounds. Instead, Kd values for 

the metals must be obtained directly from literature sources. Kd values for all metals, except lead, were 

obtained from U.S. EPA (1996a). U.S. EPA (1996a) provides values for Kd that are based on pH, and are 

estimated by using the MINTEQ2 model, which is a geochemical speciation model. The MINTEQ2 model 

analyses were conducted under a variety of geochemical conditions and metal concentrations. The

MINTEQ2 pH-dependent Kd values were estimated by holding constant the iron oxide at a medium value 

and the f at 0.002. For arsenic, hexavalent chromium, selenium, and thallium, empirical pH-dependent 

Kd values were used.

Kd value for lead was obtained from the following:

Parameters and Assessing Transport of Environmentally Released Radionuclides Through 

Agriculture.” Oak Ridge National Laboratory, Oak Ridge, Tennessee. 

Mercuric Compounds Both watershed erosion and direct atmospheric deposition can be important 

sources of mercury to a water body (U.S. EPA 1997g). There appears to be a great deal of variability in 

the processing of mercury among water bodies. This variability is primarily a result of the 

characteristically wide range of chemical and physical properties of water bodies that influence the levels of 

methylated mercury. Some of the mercury entering the water body is methylated predominately through 

biotic processes (U.S. EPA 1997g). In the absence of modeling site-specific water body properties and 

biotic conditions, consistent with U.S. EPA (1997g), U.S. EPA OSW recommends 85 percent of total 

mercury in surface water is assumed to be divalent mercury and the remaining mass as methyl mercury. 

For the fish ingestion pathway, the DRAS converts the total mercury in the surface water to the methyl 

mercury fraction by multiplying the total mercury concentration in a second order stream by 0.15 to 

determine the methyl mercury concentration. Kd values for mercury and methyl mercury were obtained 

from U.S. EPA (1996a). The Kd value for methyl mercury was obtained from U.S. EPA (1997g).

Aquatic Toxicity Reference Values (Aquatic TRVs) 

Ecological benchmarks were developed for the protection of the aquatic community. These ecological 

benchmarks are referred to as toxicity reference values (TRVs) and were developed from a variety of 

ecological receptors based on the availability of data for a given waste constituent. The TRV is developed 

to protect the entire community, not one particular species. In general, TRVs (the measurement endpoints) 

were selected for consistency with the Agency's “Framework for Ecological Risk Assessment” (U.S. EPA 

1992b). Region 6 believes the ecological analysis is conservative with respect to the overall assessment 

endpoint (e.g., sustainability of the reproducing populations) because of the way the source, fate and 

transport parameters are set and how the TRVs are developed. 

The ecological assessment focused on inferring the sustainability of populations and communities within 

the aquatic ecosystem. Therefore, TRVs were derived from measurement endpoints (i.e., reproductive, 

developmental, growth, survival, and mortality) from which such inferences could be made. Reproductive 

studies (e.g., number of viable young per female) were preferred over other endpoints. The aquatic TRVs 

defaulted to a more conservative no effects level (or concentration) approach for ecological receptors. For 

populations of fish and aquatic invertebrates (represented by daphnids), a hierarchical approach was taken 

for use of data sources in deriving aquatic TRVs. The first choice was the final chronic values (FCVs) 

from the Ambient Water Quality Criteria (AWQC) effort by the EPA Office of Water (U.S. EPA 1998a). 

If these benchmarks were not available, then a freshwater aquatic TRV was selected from the draft 

Protocol for Screening Level Ecological Risk Assessment at Hazardous Waste Combustion Facilities 

(U.S. EPA. 1998b). Finally, TRVs were selected from the Toxicological Benchmarks for Screening 

Potential contaminants of Concern for Effects on Aquatic Biota (Suter and Tsao, 1996).

A.1.3	 BIOTRANSFER FACTORS FOR ANIMALS 

Bioconcentration and Bioaccumulation Factors for Chemicals in Fish 

Bioconcentration and bioaccumulation factors for fish are used for various compounds, depending on the 

K value of the organic compound. Bioconcentration factors for fish (BCF ) were used for organics with ow	 fish 

a log K value less than 4.0; and for metals (except lead and mercury). Bioaccumulation factors for fish ow 

(BAF ) were used for organics with a log K value greater than 4.0, lead, and mercuric compounds. fish	 ow 

Bioconcentration Factors for Chemicals in Fish (BCFfish ) 

BCFfish is the ratio of the chemical concentration in fish to the chemical concentration in the water column 

where the fish is exposed. It accounts for uptake of chemicals by fish from water passing across the gills. 

BCF values for fish were used for all organic compounds with a log K of less than 4.0 (cutoff value with 

BAFfish) and for all metals, except lead and mercury, as cited in U.S. EPA (1995a). This implies that the 

concentration of chemical in the fish is only due to water intake by the fish, and compounds with a log K 

ow 

ow 

of less than 4.0 are assumed not to bioaccumulate. 

BCF values reported in the DTSD Appendix are either: 

1) Geometric mean of a valid number of field-measured values obtained from various field 

studies (or) 

2) Geometric mean of laboratory-measured values obtained from various experimental 

studies (or) 

3) Estimated values calculated using a correlation equation 

NOTE:	 When only one valid field-measured value for a chemical was found in the 

literature, the higher of the field-measured value and the geometric mean of 

laboratory-measured values, was used. 

In general, field measured BCFs were assumed to be based on total (dissolved and suspended) water 

column concentrations; and laboratory measured BCFs were assumed to be based on dissolved water 

column concentrations. This distinction is important for compounds with a log K of greater than or equal 

to 4.0, because significant amounts of a chemical can partition into the suspended sediment organic carbon 

ow 

(or particulate phase) of the water column. For compounds with a log K of less than 4.0, most of 

chemical is associated with the dissolved phase of the water column and negligible amounts of chemical is 

associated with the suspended sediment phase in the water column. Therefore, for compounds with a log 

Kow of less than 4.0, BCF values based on dissolved chemical water concentrations in the water column are 

essentially the same as BCF values based on total (dissolved + suspended) chemical water concentrations in 

the water column. 

ow 

The DTSD does not recognize differences in total versus dissolved water concentrations when calculating 

fish concentrations from BCF values for compounds with a log K of less than 4.0. Since, dissolved fish	 ow 

water concentrations is the major contributing factor from compounds with a log K of less than 4.0, all 

BCFfish values (irrespective of whether they were derived using total or dissolved water concentrations) can 

be multiplied by chemical concentration in the dissolved water column (Cdw) to calculate fish 

concentrations. This assumption is necessary because (1) literature data is often unclear if the water 

concentrations are dissolved or total concentrations, and (2) most of the literature reviewed indicated that 

ow

Appendix A-1 October 2008 

laboratory experiments were conducted using filtered or distilled water; or the experiments were conducted 

using fresh water, but were filtered before analyses for water concentrations. 

Organics For organics with a log Kow value of less than 4.0, BCFfish values were obtained from either of 

two methods: 

C	 Field-measured or laboratory-measured values from various experimental studies were 

evaluated by U.S. EPA (1998b). This information is summarized in the following 

document: 

U.S. EPA. 1998b. Screening Level Ecological Risk Assessment Protocol for 

Hazardous Waste Combustion Facilities. Draft Interim Final. April. 

Field-measured data is only (1) available for a limited number of compounds, and 

(2) based on a single study. In such cases, the field-measured value or the geometric mean 

of field-measured values were compared with the geometric mean of laboratory-measured 

values, and the higher one used. A detailed discussion on sources of BCF values and 

methodology followed are provided in Appendix C of U.S. EPA (1998b). 

C	 When measured values were not available or could not be evaluated, the following 

correlation equation recommended by Lyman, Reehl, and Rosenblatt (1982) was used: 

Equation A-1-4 

Correlation Equation A-1-4 was developed by the following: 

C Veith, G.D., K.J. Macek, S.R. Petrocelli, and J. Caroll. 1980. “An Evaluation of Using 

Partition Coefficients and Water Solubility to Estimate Bioconcentration Factors for 

Organic Chemicals in Fish.” Journal of Fish. Res. Board Can. Prepublication Copy. 

Veith, Macek, Petrocelli, and Caroll (1980) measured BCF values for four fish species in flow-through 

laboratory studies that were exposed to a wide range of organic chemicals. BCFfish values calculated by 

using correlation Equation A-1-4 are (1) based on dissolved water concentrations, and (2) not 

lipid-normalized. 

Metals For metals (except lead and mercury), BCFfish values are measured values obtained from various 

literature studies, as cited in U.S. EPA (1998b). Measured values from various experimental studies were 

evaluated by U.S. EPA (1998b). Detailed discussion and sources of measured values were provided in 

U.S. EPA (1998b). For lead, a BAF is more applicable than a BCF as it tends to bioaccumulate. 

Mercuric Compounds For mercuric compounds, a BAF is more applicable than a BCF as they tend to 

bioaccumulate. Therefore the BAFfish value for methyl mercury was obtained from U.S. EPA (1997g) for a 

trophic level 4 fish. 

Bioaccumulation Factors for Chemicals in Fish (BAFfish ) 

BAFfish is the ratio of the chemical concentration in fish to the chemical concentration in the water body 

where the fish are exposed. The BAFfish accounts for uptake of chemicals by fish from water and sediments 

passing across the gills, and from consumption of various foods including plankton, daphnids, and other 

A-1-11 
 

RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

fish. BAFs for fish were used for organic compounds (except PCBs, PCDDs, and PCDFs) with a log Kow 

greater than 4.0, lead and mercuric compounds. 

For compounds with a log K of greater than or equal to 4.0, chemicals can significantly partition into the 

suspended sediment organic carbon (or particulate phase) of the water column. Therefore, BAF values 

should be based on total (dissolved and suspended) water column concentrations. BAFs reported are either: 

ow 

1)	 Geometric mean of field-measured values obtained from various experimental studies (or) 

2)	 Predicted values calculated by multiplying a food chain multiplier (FCM) with a geometric 

mean of various laboratory measured BCFs. A FCM is the ratio of a BAF to a BCF, and 

is used to account for food chain biomagnification from a lower to a upper trophic level 

(or) 

3)	 Predicted values calculated by multiplying a FCM with an estimated BCF. BCFs were 

estimated using correlation Equation A-1-4. 

NOTE:	 When only one valid field-measured value for a chemical was found in the 

literature, the higher of the field-measured value and the geometric mean of 

laboratory-measured values, was used. 

In general, (1) field-measured BAFs were assumed to be based on total (dissolved and suspended) water 

column concentrations, (2) laboratory-measured BCFs, and therefore, the BAFs predicted from them, were 

assumed to be based on dissolved water column concentrations, and (3) estimated BCFs using correlation 

Equation A-1-4, and therefore, the BAFs predicted from them, were assumed to be based on dissolved 

water column concentrations. In addition, field-measured BCFs, for compounds with a log K greater than 

4.0, were assumed to be equal to BAFs, because the tissue concentrations are a result of uptake of water 

(dissolved and suspended), sediment, and various trophic level food. 

ow 

For consistency, all field-measured BAF (or BCF) values were adjusted according to the methodology 

specified in U.S. EPA (1995e) to include only the dissolved water column fractions; (i.e., the BAFs based 

on total water concentrations were converted to BAFs based on dissolved water concentrations). This was 

done, so that all BAFfish values (based on dissolved water concentrations) can be multiplied by the chemical 

concentration in the dissolved water column (Cdw) to calculate fish concentrations. 

In U.S. EPA (1995a), BAF values were estimated based on the models developed for the limnetic 

ecosystem by the following: 

C	 Thomann, R.V. 1989. “Bioaccumulation Model of Organic Chemical Distribution in 

Aquatic Food Chains.” Environmental Science and Technology. 23(6):699-707. 

and, for the littoral ecosystem by the following: 

C Thomann, R.V., J.P. Connolly, and T.F. Parkerton. 1992. “An Equilibrium Model of 

Organic Chemical Accumulation in Aquatic Food Webs with Sediment Interaction.” 

Environmental Toxicology and Chemistry. 11:615-629. 

BAF values were predicted by multiplying a laboratory-measured or predicted BCF by a FCM. The 

Thomann (1989) and Thomann, Connolly, and Parkerton (1992) models were adopted by U.S. EPA, 

Office of Water, for the Great Lakes Water Quality Initiative in 1993. In 1995, U.S. EPA, Office of 

Water, developed BAFs based on the following study: 

A-1-12

Appendix A-1 October 2008 

C Gobas, F.A.P.C. 1993. “A Model for predicting the bioaccumulation of hydrophobic 

organic chemicals in aquatic food-webs: application to Lake Ontario.” Ecological 

Modelling. 69:1-17. 

The Gobas (1993) model was adopted to develop the latest water quality criteria and is provided in the 

following two documents: 

C U.S. EPA. 1995d. Water Quality Guidance for the Great Lakes System. Supplementary 

Information Document. Office of Water. EPA-820-B-95-001. March. 

C	 U.S. EPA. 1995e. Great Lakes Water Quality Initiative. Technical Support Document 

for the Procedure to Determine Bioaccumulation Factors. Office of Water. 

EPA-820-B-95-005. March. 

The Gobas (1993) food-chain model was preferred because, unlike the Thomann (1989) model, it includes 

both benthic and pelagic food chains, thereby estimating exposure of organisms to compounds from both 

the sediment and the water column. Other inherent drawbacks of the Thomann (1989) model were that the 

model: (1) did not take into account metabolism, biotransformation, degradation, persistence, or seasonal or 

temporal variability, (2) is extremely sensitive to certain input parameter such as the lipid content, 

(3) incorrectly adopted FCMs, (4) is questionable in its assumption that the system is at steady state or in 

equilibrium, and (5) had little application for compounds with a log K greater than 6.5, because the 

sediment route of exposure was not considered. 

ow 

The Gobas (1993) model: (1) accounts for metabolism, but sets the metabolic rate to zero because of lack 

of data for individual compounds, (i.e., the metabolism is assumed not to occur), (2) incorporates the 

concentration of the compound in both the sediment and the water column, the sediment route being 

especially useful for compounds with a log K greater than 6.5, and (3) includes the disequilibrium 

between concentrations of the compounds in sediment and the water column. Although the Thomann, 

Connolly, and Parkerton (1992) model accounts for sediment interaction, according to U.S. EPA (1995d), 

the Gobas (1993) model required fewer input parameters which could be more easily specified. 

ow 

The following equation cited in U.S. EPA (1995e) was used to convert the BAF based on total water 

concentrations to a BAF based on dissolved water concentrations: 

Equation A-1-5 

where 

f fd = fraction of chemical that is freely dissolved in water 

DOC = concentration of dissolved organic carbon, kg organic carbon / L water 

POC = concentration of particulate organic carbon, kg organic carbon / L water 

Since, the Gobas (1993) model was derived from a study conducted at Lake Ontario, DOC and POC 

values for Lake Ontario were used. Values cited in U.S. EPA (1995e) were: 

DOC	 = 2 x 10 -6 kg/L 

A-1-13 
RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

POC = 7.5 x 10-9 kg/L 

A BAF based on dissolved water concentrations can be calculated from a BAF based on total water 

concentrations as follows: 

Equation A-1-6 

FCMs were obtained from Table 2 of U.S. EPA (1995e). U.S. EPA (1995e) provided FCMs as a function 

of log K in increments of 0.1 for trophic level 2, 3, and 4 aquatic organisms. Humans are assumed to 

consume trophic level 3 or 4 fish. The higher FCM value of trophic levels 3 and 4 was used. When the 

ow 

log K value of a chemical was between two log K values listed in Table 2 of U.S. EPA (1995e), the ow ow 

FCM for the next highest log K value was used. ow 

Organics For all organics (except PCBs, PCDDs and PCDFs) with a log K greater than or equal to 4.0, 

the FCM, which accounts for accumulation through the food chain in addition to water, becomes greater 

than 1. Therefore, a BAFfish , which takes the food chain into consideration, is more appropriate than a 

BCFfish

For all organics with a log K greater than or equal to 4.0, BAFs were derived using one of following three ow

Both field and laboratory measured values were derived from various literature sources cited in

Metals (lead) For lead, the food-chain multiplier becomes greater than 1; therefore, a BAF is more 

appropriate. The BAFfish value for lead was obtained as a geometric mean from various literature sources 

described in U.S. EPA (1998b). Since metals are assumed insoluble under neutral conditions, the dissolved 

and total water concentrations are almost equal. However, for consistency, the BAFfish value for lead was 

adjusted for dissolved fractions. 

Mercuric Compounds For mercuric compounds, a BAF is more applicable than a BCF as they tend to 

bioaccumulate. Therefore the BAFfish value for methyl mercury was obtained from U.S. EPA (1997g) for a 

trophic level 4 fish. 

A.1.4 HUMAN HEALTH BENCHMARKS 

DRAS incorporates human health benchmarks as reference doses and reference concentrations for 

noncarcinogens, and as cancer slope factors for carcinogens. Reference dose (RfD) is defined as a daily 

intake rate of a compound estimated to pose no appreciable risk of deleterious effects over a specific 

exposure duration (U.S. EPA 1989). Reference concentration (RfC) is defined as the concentration of a 

compound estimated (with uncertainty spanning perhaps an order of magnitude) to pose no appreciable risk 

A-1-14 
RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

of deleterious effects over a specific exposure duration (U.S. EPA 1989). EPA defines cancer slope factors 

as “ used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially 

carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit, on the 

increased cancer risk from a lifetime exposure to an agent by ingestion [or inhalation]”. 

Updated Toxicity Data 

EPA reviewed all existing toxicity reference data in DRAS for outdated or errant values. To do so, EPA 

downloaded the 2004 version of the Region 9 Preliminary Remediation Goals (PRGs)(U.S. EPA 2004a) 

toxicity reference values to those in DRAS. We also reviewed Agency sources for any other changes which 

may have occurred after the 2004 PRG table was prepared. 

Some of the updates were straightforward such as an unambiguous revision to the Integrated Risk 

Information System (IRIS – EPA’s highest standard source for toxicity data). Other discrepancies required 

the review of Agency toxicologists in determining the appropriate default data for use in DRAS. In 

consideration of the exposure scenarios evaluated in the delisting program, EPA selected toxicity data in 

accordance with the hierarchy described in the December 2003 Memorandum from Michael B. Cook (U.S. 

EPA 2003), as did Region 9 in developing the 2004 PRG list. The types of pathway evaluations are very 

similar to those applied for Superfund-site evaluations. The hierarchy recommended is as follows: 

IRIS is the first tier of the recommended hierarchy as the generally preferred source of 

human health toxicity values. IRIS generally contains reference doses (RfDs),reference 

concentrations (RfCs), cancer slope factors, drinking water unit risk values, and inhalation 

unit risk values that have gone through a peer review and EPA consensus review process. 

IRIS normally represents the official Agency scientific position regarding the toxicity of 

the chemicals based on the data available at the time of the review. 

The second tier is EPA’s [Provisional Peer Reviewed Toxicity Values] PPRTVs. 

Generally, PPRTVs are derived for one of two reasons. First, the [Superfund Health Risk 

Technical Support Center] STSC is conducting a batch wise review of the toxicity values 

in [the EPA Health Effects Summary Tables] HEAST (now a Tier 3 source). As such 

reviews are completed, those toxicity values will be removed from HEAST, and any new 

toxicity value developed in such a review will be a PPRTV and placed in the PPRTV 

database. Second, Regional Superfund Offices may request a PPRTV for contaminants 

lacking a relevant IRIS value. The STSC uses the same methodologies to derive PPRTVs 

for both. 

The third tier includes other sources of information. Priority should be given to sources 

that provide toxicity information based on similar methods and procedures as those used 

for Tier I and Tier II, contain values which are peer reviewed, are available to the public, 

and are transparent about the methods and processes used to develop the values. 

Consultation with the STSC or headquarters program office is recommended regarding the 

use of the Tier 3 values for Superfund response decisions when the contaminant appears to 

be a risk driver for the site. In general, draft toxicity assessments are not appropriate for 

use until they have been through peer review, the peer review comments have been 

addressed in a revised draft, and the revised draft is publicly available. 

In October 2008, IRIS and PPRTV were checked once more for updates and added to DRAS in accordance 

with the Cook Memorandum.

Appendix A-1 October 2008 

Explanation of Calculated Toxicity Benchmark Values – Route-to-Route Extrapolation 

To calculate missing benchmarks, available benchmarks can be employed using a methodology referred to 

as route-to-route extrapolation. Route-to-route extrapolation is when a toxicity factor for one route of 

exposure (i.e. ingestion) is converted into a toxicity factor for another route of exposure (i.e. inhalation). 

DRAS includes route-to-route extrapolations from the R9 2004 PRGs based on criteria set forth in 

“Methods for Derivation of Inhalation Reference Concentrations and Application of Inhalation Dosimetry” 

(U.S. EPA 1994g). Specifically, EPA believed that the most appropriate way to evaluate a large group of 

chemicals for route-to-route extrapolations was by applying the following criteria from the 1994 report: 

Oral data should not be used for route-to-route extrapolation in the following instances: 

(1)	 when groups of chemicals are expected to have different toxicity by the two 

routes; for example, metals, irritants, and sensitizers; . . . 

(6)	 when short-term inhalation studies, dermal irritation, in vitro-studies, or 

characteristics of the chemical indicate potential for portal-of-entry effects at the 

respiratory tract, but studies themselves are not adequate for an RfC development.

 The following databases were used for the evaluation: 

(a) EPA’s database for chemicals determined to be extremely hazardous substances after release to 

ambient air. These include chemicals assigned an EPA Level of Concern (LOC) as found in the 

document: “Technical Guidance for Hazards Analysis: Emergency Planning for Extremely 

Hazardous Substances” (U.S. EPA 1987); 

(b) Emergency Planning Response Guideline (ERPG) values for protection of the general public 

from the acute toxic and/or debilitating effects of chemicals in ambient air. ERPGs are developed 

by the American Industrial Hygiene Association 

(http://www.orau.gov/emi/scapa/erpgdefinitions.htm) (AIHA 2005); 

(c) U.S. DOE Temporary Emergency Exposure Limit (TEEL) values for protection of Federal 

workers and contractors at DOE facilities from the acute toxic and/or debilitating effects of 

chemicals in ambient air. TEELs are developed by methodologies similar to the ERPGs but 

include more chemicals (http://www.orau.gov/emi/scapa/teels.htm ) (U.S. DOE 2005) ; and 

(d) NIOSH Recommended Exposure Limit (REL) values for work place exposure. This 

encompasses chemicals that have been assigned a specific time-concentration exposure limit in 

ambient air because they are documented to be respiratory irritants (even for a healthy worker) in 

ambient air in the absence of exposure protection. (www.cdc.gov/niosh/92-100.html) (U.S. DHHS 

1992). 

DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (a) include: 

Acrylamide; Aldrin; Benzyl Chloride; o-Cresol; Endosulfan; Endrin; Disulfoton; Furan; 

N-Nitrosodimethylamine; Parathion; Pentachlorophenol; Phenylmercuric acetate; Phorate;

hexachlorobutadiene; 3,3-dimethoxybenzidine; 2,4-dichlorophenol; pentachlorobenzene; DDE; 

DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (d) include: 

Acetone - nose and throat irritant
 

Acetonitrile - nose and throat irritant
 

Bromoform - respiratory irritant
 

Dichlorobenzenes (all isomers) - upper respiratory irritants
 

Dichloroethylenes (all isomers) - mucous membrane irritants; narcosis;
 

Dimethylphthalate - upper respiratory irritant
 

Ethyl acetate - respiratory and eye irritant
 

Methyl acetate - upper respiratory irritant
 

Pentachlorophenol - upper respiratory irritant
 

Phenylenediamine - bronchial irritant and asthma inducer
 

Strychnine - convulsions
 

Trichloropropane - mucous membrane irritant; narcosis;
 

Consequently, for the above chemical constituents, we recommended against using route-to-route 

extrapolation from oral route data to derive inhalation toxicity factors. 

For the remainder of the chemicals in the R9 2004 PRGs where extrapolation is used, the use of the 

route-to-route extrapolation in DRAS could be adopted on the basis that direct exposure effects of the 

remaining chemicals on the lung or respiratory system (of humans or animals) could not be identified. 

However, there could still be some significant uncertainties in the reliability of inhalation toxicity factors 

derived in this way. The primary uncertainty would probably be due to the rate of metabolism of a given 

chemical in the liver or lung and how that factor affects the ultimate level of absorption and transport to 

target organs. In the event that one of these route-to-route values becomes the basis for potentially denying 

a delisting petition, Region 5 recommends that the reference value be further investigated to reduce this 

uncertainty. In order to carry on the evaluation further, published literature studies on the metabolism or 

pharmacology of the individual chemicals would need to be located and reviewed. 

The discussion above covers the concept of using route-to-route extrapolation from oral route data to 

derive inhalation toxicity factors. In the R9 2004 PRGs, there are also some instances where DRAS lists 

oral toxicity factors that were apparently derived from IRIS verified inhalation toxicity factors. The use of 

this extrapolation procedure would also be subject to uncertainty. For the purposes of making an expedited 

screening level evaluation, we propose the following caveat: the route-to-route extrapolation from 

A-1-17 
RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

inhalation to oral should only be used when there is well documented evidence that exposure via the 

inhalation route results in adverse effects at organs or organ systems that are distant from the lung and 

respiratory tract (e.g., liver, kidney, thyroid, sex organs). The evaluation based on applying the above 

caveat is shown below: 

RfDO for Acetonitrile: IRIS reports health effects distant from the lung, therefore the 

route-to-route extrapolation is satisfactory. 

RfDO for Benzyl chloride: R9 lists an RfC referenced to NCEA. We recommend not using the 

route-to-route extrapolation until we are able to verify the health effects reported in this reference. 

RfDO for Chlorodifluoromethane: IRIS reports health effects distant from the lung, therefore the 

route-to-route extrapolation is satisfactory. 

RfDO for Chloromethane: Because IRIS states that exposure to chloromethane can essentially 

occur only through the vapor phase, derivation of an oral toxicity factor is not necessary. 

RfDO for 3-Chloropropene (Allyl chloride): IRIS reports peripheral neurological effects in humans 

and liver and kidney degenerative effects in lab animals; under the assumption that oral exposure 

to Allyl Chloride could occur, the route-to-route extrapolation is satisfactory; 

RfDO for 1,2-Dichloropropane: IRIS reports that the observed adverse effects were seen only in 

the nasal tissue and respiratory epithelium; therefore, route-to-route extrapolation should not be 

used; 

RfDO for 2-Nitropropane: IRIS reports development of focal hepatocellular nodules and focal liver 

necrosis in lab animals with no significant effects on the respiratory tract; under the assumption 

that oral exposure could occur to Nitropropane, the route-to-route extrapolation is satisfactory. 

Provisional Toxicity Data, Multiple CAS ID Numbers, Multiple Valence States, and Data Based on a 

Mixture of Compounds 

Approximately 26 potential waste constituents have provisional toxicity data, multiple CAS identification 

numbers, valence states, or toxicity data based on a mixture of compounds. We individually evaluated 

these using the following acronyms and conversion algorithms: 

CSFO – Oral Cancer Slope Factor 

CSFI

 – Inhalation Cancer Slope Factor 

IUR – Inhalation Unit Risk (cancer) 

RfDO – Oral Reference Dose 

RfDI

 – Inhalation Reference Dose 

RfC – Inhalation Reference Concentration 

CalEPA – California EPA

Acrylonitrile 

1) There is a single listed CAS number, therefore no problem.
 

2) The listed DRAS CSFO is found in IRIS, therefore retain.
 

3) An IUR value of 6.8E-05 (ug/m ) I
 

3 -1 is found in IRIS and we used this value to calculate the CSF . 

The calculated CSF is 0.238 (mg/kg-day) -1 which is the same as the listed DRAS value, therefore no 

change necessary. 

I

3 4) An RfC value of 0.002 (mg/m ) is found in IRIS, and we used this value to calculate RfD .I

The calculated RfD is 0.00057 (mg/kg-day); therefore we changed the listed DRAS value. I

Arsenic 

1) The listed DRAS values for CSFO and RfDO are correct values based on IRIS. 

3 -1 2) An IUR value of 4.3E-03 (ug/m ) is found in IRIS, and we used this value to calculate a CSF of I 

15.05 (mg/kg-day) -1. Since this is the same as the listed DRAS value, no change was necessary. 

3) Note: IRIS has only one set of toxicity factors for Arsenic. These should be applied to analytical data 

for Ar(III), Ar (V) or Total Arsenic. For purposes of evaluating arsenic risk, EPA generally evaluates 

arsenic risk as Total arsenic unless a specific regulation spells out how arsenic should be analyzed and 

reported. If the DRAS program directs petitioners to report results for Ar(III) and Ar (V), there is still only 

one set of toxicity factors available. 

4) We didn’t need to use CalEPA values. 

Benzo(k)fluoranthene 

1) The listed DRAS CSFO value of 0.073 (mg/kg-day) -1 is correct based on use of the TEF factor 

approach based on the CSFO for Benzo(a)pyrene. 

I

-1 2) The listed DRAS CSF of 0.031 (mg/kg-day) is the result of applying the TEF factor approach based 

on the EPA Region 4 finding of a published inhalation exposure study for Benzo(a)pyrene in hamsters as 

reported by NCEA (Thyssen 1981). This approach is more specific than just assuming route-to-route 

extrapolation from oral-to-inhalation exposure and therefore acceptable. This approach may be superseded 

when the Agency publishes a new IRIS file for PAHs. 

Benzo(a)anthracene 

The currently listed DRAS values are correct. The listed CSF of 0.31 (mg/kg-day) -1 is acceptable based 

on the same rationale used above for Benzo(k)fluoranthene. 

I 

Benzo(b)fluoranthene 

A-1-19 
RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

The currently listed DRAS values are correct. The listed CSF of 0.31 (mg/kg-day) -1 is acceptable based 

on the same rationale used above for Benzo(k)fluoranthene. 

I 

Benzo(a)pyrene 

The currently listed DRAS values are correct. The listed CSF of 3.1 (mg/kg-day) -1 is acceptable based on 

the same rationale used above for Benzo(k)fluoranthene. 

I 

Chlordane 

1) The listed DRAS CSF and CSF values are the same as IRIS values, therefore no change is necessary. O I 

3 2) An RfC value of 0.0007 (mg/m )is found in IRIS and we used this value to calculate RfD of 0.0002 

(mg/kg-day). We replaced the existing value with the new calculation. 

I 

3) IRIS states that the toxicology studies used to derive the toxicity factors were performed by 

administering Technical grade Chlordane to animals for both the oral and inhalation exposure routes. IRIS 

gives a definition of Technical grade Chlordane. Therefore, if the petitioner performs an analysis for 

Technical grade Chlordane or some other form of Chlordane, there is only one set of toxicity factors. 

Chloroethane (Ethyl Chloride) 

3 1) An RfC value of 10 (mg/m )is found in IRIS and we used this value to calculate RfD of 2.86 

(mg/kg-day). We replaced the existing value with the new calculation. 

I 

2) The other listed DRAS toxicity values are correct. 

3) The oral cancer slope factor could not be verified and a superseded document from NCEA did not 

match with R9's estimates of the inhalation slope factor, therefore we do not recommend that the 

carcinogenic toxicity factors be left blank at this time. 

Chloroform 

1) When the IRIS file for chloroform was revised (Oct. 2001), EPA made a significant change in its 

interpretation of the toxicological evidence. In particular, IRIS determined that ingested chloroform acts by 

non-linear Mode of Action – chloroform must induce cytotoxicity as a prerequisite for the induction of 

tumors in rodents. In addition, at dose levels below the oral RfD, chloroform does not induce the level of 

cytotoxicity and regenerative hyperplasia needed to induce the tumorigenic response. Therefore, the RfD 

was determined to be an adequate dose benchmark for cancer prevention. The following is the explanation 

found in the IRIS file: 

In the case of chloroform, the mode of action of carcinogenicity is reasonably well 

understood. Available data indicate that chloroform is not strongly mutagenic and 

chloroform is not expected to produce rodent tumors via a mutagenic mode of action 

(ILSI, 1997). Rather, there is good evidence that carcinogenic responses observed in 

animals are associated with regenerative hyperplasia that occurs in response to 

cytolethality (ILSI, 1997; U.S. EPA, 1998a,b). Because cytolethality occurs only at 

exposure levels above some critical dose level, a nonlinear approach is considered the most 

appropriate method for characterizing the cancer risk from chloroform. 

A-1-20 
 

RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

The Proposed Guidelines for Carcinogenic Risk Assessment (U.S. EPA, 1996) state that 

when the mode-of-action analysis based on available data indicates that the carcinogenic 

response is secondary to another toxicity that has a threshold, the margin-of-exposure 

analysis performed for toxicity is the same as is done for a noncancer endpoint, and an 

RfD for that toxicity may be considered in the cancer assessment. For chloroform, 

available evidence indicates that chloroform-induced carcinogenicity is secondary to 

cytotoxicity and regenerative hyperplasia; hence, the Agency relies on a nonlinear 

dose-response approach and the use of a margin-of-exposure analysis for cancer risk. The 

Agency has also chosen not to rely on a mathematical model to estimate a point of 

departure for cancer risk estimate, because the mode of action indicates that cytotoxicity is 

the critical effect and the reference dose value is considered protective for this effect. 

For more discussion of margin of exposure (MOE), see the Toxicological Review for 

Chloroform. Based on the kidney tumor of the drinking water study (Jorgenson et al., 

1985), a point of departure (Pdp or LED10) of 23 mg/kg/day can be calculated using 

quantitative modeling of tumor dose-response data. Comparing the Pdp to the RfD of 0.01 

mg/kg/day leads to a MOE of 2,000, which is considered large. Thus, in this case, the RfD 

for noncancer effect is also considered adequately protective of public health for cancer 

effects by the oral route, on the basis of the nonlinear dose response for chloroform and the 

mode of action for both cancer and noncancer effects having a common link through 

cytotoxicity. 

We concluded that the existing CSFO for chloroform be deleted and the Cal EPA cancer slope factor should 

not be adopted. 

2) The listed DRAS CSF value should be rounded off to 0.081 (mg/kg-day) -1. I 

3) The listed DRAS RfDO value from IRIS is acceptable to use. 

4) The 2004 Region 9 PRG referenced a value from NCEA for the RfC, 0.049 mg/m .3 We could not 

locate this reference. The latest Region 9 PRG (2008) lists a value derived from ATSDR. An RfC of 

9.93E-02 (mg/kg day) was derived from a chronic inhalation minimum risk level (MRL) published by 

ATSDR in 1997. 

Chromium 

1) For Cr(III), IRIS states that the following factors cannot be developed: RfC (RfD ), CSF , and IUR I O 

(CSF ); therefore deleted those values from DRAS; for Cr(III), DRAS lists only an RfD of 1.5 

(mg/kg-day). 

I O 

2) For Cr (VI), the listed DRAS RfDO is correct; 

3 3) Since the IRIS RfC is 8E-06 (mg/m ) the DRAS RfD should be 2.3E-06 (mg/kg-day). This RfD is for I I

Cr(VI) mists and aerosols (e.g., chromium plating operations). If the potential exposure is more likely to 3 be from Cr(VI) particulates, IRIS suggests that an RfC of 1E-04 (mg/m ) should be used, and the

corresponding RfD is 2.9E-05 (mg/kg-day). I

3 -1 -1 4) For Cr (VI), the IRIS IUR is 1.2E-02 (ug/m ) and the calculated CSF is 42 (mg/kg-day) . As stated I

in IRIS, industrial worker exposure was known to be from Cr(VI)-Cr(III) mixtures, so there is some 

A-1-21 
 

 

RCRA Delisting Technical Support Document 

Appendix A-1 October 2008 

uncertainty in the actual slope factor that would be due to Cr(VI) alone. The Cr(VI):Cr(III) ratio was 

assumed to be at least 1:6 for development of the slope factor; therefore, the highest possible CSF would 

be 7 x 42 = 294 (mg/kg-day) -1. Therefore, we used this latter value if exposure needs to be modeled as due 

to Cr(VI) alone; if the suspected exposure would be due to a mixture of valences, we suggest using the 42 

(mg/kg-day) -1 value.

Chrysene 

The currently listed DRAS values are correct. The listed CSF of 0.0031 (mg/kg-day) -1 is acceptable 

based on the same rationale used above for Benzo(k)fluoranthene. 

I 

Cumene 

1) The listed DRAS RfDO is correct. 

3 2) Since the IRIS RfC is 0.385 (mg/m ), the calculated RfD should be 0.11 (mg/kg-day). I

Dibenz(a,h)anthracene 

The currently listed DRAS values are correct. The listed CSF of 3.1 (mg/kg-day) -1 is acceptable based on 

the same rationale used above for Benzo(k)fluoranthene.

1,2-Dibromo-3-chloropropane 

3 1) Since the IRIS RfC value is 0.0002 (mg/m ), the calculated DRAS RfD should be 5.71E-05

(mg/kg-day); 

I

2) The EPA Region 9 PRG reference from 2004 originally recommended a route-to-route extrapolation for 

RfD. However, EPA Superfund has since provided a provisional RfDO under PPRTV and that value is 

used as the default in DRAS. 

3) The EPA Region 9 PRG reference from 2004 originally recommended slope factors from California 

EPA. However, EPA Superfund has since provided provisional slope factors under PPRTV and those 

values are used as the default in DRAS. 

1,1-Dichloroethane 

3 1) The listed HEAST RfC value of 0.5 (mg/m ) is correct and is the only provisional toxicity factor

available until the IRIS file is revised. Therefore, the calculated RfD value should be 0.143 (mg/kg-day) in 

DRAS; 

I 

2) The EPA Region 9 PRG reference from 2004 originally recommended a route-to-route extrapolation for 

RfD. However, EPA Superfund has since provided a provisional RfDO under PPRTV and that value is 

used as the default in DRAS. 

3) There are no acceptable cancer slope factors available for this chemical. We suggest not using the 

CalEPA listed slope factors that were derived from an NCI 1977 study in rats. The EPA IRIS program 

re-evaluated this study and determined that it contained too many confounding results to use for deriving a 

CSFO value.

Dichloropropane (cis-, trans-, mixture) 

1) In the “mixture” heading, all of the listed DRAS values are correct except for the RfD .I Since the IRIS 3 RfC value is 0.02 (mg/m ), the calculated DRAS RfD should be 0.00571 (mg/kg-day);

2) For the cis- and trans- isomers, DRAS has an additional value of 0.175 (mg/kg-day) -1 for the CSF O. 

We could not determine where it came from and do not think it should be used;

Dinitrotoluene (2,4-; 2,6-; mixture) 

2,4-DNT: The current DRAS RfDO is correct. It should be acceptable to use the CSFO listed for the 

“mixture” since it is found on IRIS. We could not determine the origin of the values listed for RfD and 

RfC, so we suggest not using. 

2,6-DNT: The CSFO value listed for the mixture is the only available toxicity factor that we believe is 

appropriate. However, EPA Superfund has since provided a provisional RfDO under PPRTV for this 

isomer and that value is used as the default in DRAS. We could not determine the origin of the values

listed for RfD and RfC, so suggest not using;

Epichlorohydrin

2) Since the listed IRIS IUR value is 1.2E-06 (ug/m ) I 

3 -1, the calculated DRAS CSF should be 0.0042 -1 (mg/kg-day) (and the reference to HEAST can be changed to IRIS ).

3 3) Since the IRIS RfC is 0.001 (mg/m ), the calculated DRAS RfD should be 0.00029 (mg/kg-day).

4) Although IRIS has withdrawn the original RfDO value. EPA Superfund has provided a provisional 

RfDO under PPRTV and that value is used as the default in DRAS.

HCH and Lindane 

1) The currently listed DRAS values appear to be correct. 

2) For the missing DRAS RfDO value under “beta-“ and “alpha-“, EPA Region 9 PRGs recommended 

using the NCEA provisional values shown under the PRG column. However, this reference could not be 

located. The latest Region 9 PRG (2008) lists values derived from ATSDR. RfD s of 8.0E-03 mg/kg day 

and 6.0E-04 mg/kg day were derived from inhalation minimum risk levels (MRLs) for alpha-HCH and 

beta-HCH, respectively, published by ATSDR in 2005.

The currently listed DRAS values are correct. The listed CSF of 0.31 (mg/kg-day) -1 is acceptable based 

on the same rationale used above for Benzo(k)fluoranthene.

Lead 

There are no IRIS cancer slope factors or Reference Doses for lead. EPA bases the protective media 

concentration on an uptake-absorption model in children up to seven years old in the child model; and for a 

pregnant woman in the adult model (to provide protection to the adult and the unborn child). 

The general cleanup program policies are: lead releases to residential soil should not cause total soil lead 

concentration to exceed 400 (mg/kg); lead releases to industrial/commercial use soil (i.e., adult only 

exposure) should not cause total soil concentration to exceed 800 (mg/kg); 

Mercury 

1) The CASRN of 7439-97-6 means Hg(0) or elemental mercury. The listed DRAS RfD value and RfC 

value are correct however, there is no RfDO value for Hg(0), so it is not appropriate to use the value from 

methyl mercury. 

I 

2) Mercury and compounds: This for the inorganic Hg valence states above zero, including Hg(II), such 

as HgCl2 and HgO. The only available toxicity factor is the RfDO of 0.0003 (mg/kg-day). 

3) Methyl mercury: This is for organic mercury that has accumulated and bioconcentrated in organic 

tissues (e.g., fish, wildlife). The only available toxicity factor is the RfDO of 0.0001 (mg/kg-day). This 

constituent is not easy to measure accurately in tissues. So the default assumption is that all mercury 

detectable in organic tissues is methyl mercury; 

4) DRAS currently includes separate constituents of concern for mercury and methyl mercury due to the 

differences in both toxicity and fate and transport in the environment. Methyl mercury is listed as Mercury 

(Fish Pathway Only) while all other forms of mercury are evaluated under Mercury. 

Naphthalene 

3 1) The listed DRAS RfD is correct. Since the IRIS RfC is 0.003 (mg/m ), the DRAS RfD should be O I

8.6E-04 (mg/kg-day).

2) We recommend in this case that DRAS include the provisional Cancer Slope Factor for Naphthalene, 

even though the final decision has not yet been published in IRIS. The peer review draft of the 

Toxicological Review document (2004) states EPA’s finding that Naphthalene should be regarded as a 3 -1 probable human carcinogen by the inhalation route. The proposed IUR is 1E-04 (ug/m ) . The calculated 

provisional CSF is 0.35 (mg/kg-day) -1. I

3) It would not be appropriate to use route-to-route extrapolation to derive a CSFO from the provisional 

CSF . I The Toxicological Review document mentioned above specifically states that the data on oral 

exposure were inadequate to support derivation of a CSFO. 

Nickel 

1) The CASRN of 7440-02-0 is for nickel salts or nickel compounds. The listed DRAS RfDO of 0.02 

(mg/kg-day) should be used for ingestion of all forms of nickel except nickel subsulfide as explained below. 

I

-1 2) Use the listed R9 CSF of 0.84 (mg/kg-day) for inhalation of all forms of nickel except nickel 

subsulfide as explained below. We did not assume route-to-route extrapolation to derive a CSFO value. 

3) If nickel subsulfide needs to be retained as a DRAS constituent because of a specific industrial process, 

we can use the listed R9 CSF value of 1.7 (mg/kg-day) -1 as the DRAS value for CSF . We did not 

assume route-to-route extrapolation to derive a CSFO value. 

I I 

Polychlorinated biphenyls (PCBs) (Aroclors) 

In most PCB analyses performed by the historical EPA method, the results are presented as an amount of 

total Aroclors and/or amounts of specific Aroclors (1254, 1260, 1248, etc.). This gives very little 

information about the actual level of chlorination in the mixture. So when Aroclor analysis is performed, 

assume that the mixture is highly chlorinated and use the “high risk” slope factors: CSFO = 2 -1 -1 (mg/kg-day) ; and CSFI = 2 (mg/kg-day) . 

For non-cancer hazard, assume that the mixture is composed of the most hazardous Aroclor (1254) and use 

the RfDO = 0.00002 (mg/kg-day). In this case, it is acceptable to use route-to-route extrapolation and 

apply an RfD value of 0.00002 (mg/kg-day) because of evidence that inhalation exposure of PCBs can 

result in adverse effects at distant sites from the lung. 

I

To apply the “low risk” toxicity factors, the petitioner needs to perform a more refined sample analysis. 

For example, to obtain evidence for a low risk mixture, GC-MS analysis needs to be performed to 

accomplish an isomer group analysis that will report the results as mono- through deca- PCB homologs. 

This will yield more specific data about the chlorine content of the mixture. Then IRIS states that the 

mixture should be assumed to be low risk only if “congener or isomer analyses verify that congeners with 

more than 4 chlorines comprise < 0.5% of the total PCBs.” And by analogy, only apply the highest RfD O 

of 0.00007 (mg/kg-day) if analysis shows that the chlorine content is very low or if the mixture can be 

verified to be composed of only Aroclor 1016. 

TCDD, 2,3,7,8 

The listed DRAS CSF and CSF are correct. The only available source of toxicity factors is HEAST until 

the EPA finalizes the Dioxin Reassessment.

The listed IRIS RfDO is 0.01 (mg/kg-day). In this case, it is acceptable to apply route-to-route 

extrapolation since studies of inhalation exposure in mice showed that exposure by this route resulted in 

liver toxicity and liver tumors. Then the RfD is 0.01 (mg/kg-day). I 

Trichloroethylene (TCE) 

There is a recent EPA risk assessment which received external peer review (Trichloroethylene Health Risk 

Assessment: Synthesis and Characterization; ORD 2001). This document recommended some toxicity 

factors, in particular, a new cancer slope factor. However, EPA decided not to move ahead and finalize the 

RA document or the new IRIS file because of internal and external disagreement over some of the data 

analysis in the RA document. EPA has since initiated a consultation with the National Academy of Science 

to review parts of the RA document. When the review is complete, EPA will finalize the RA document and 

the IRIS file. But this will take some time. Meanwhile, NCEA has been reluctant to support the proposed 

new cancer slope factor or recommend using it as the provisional value. Therefore, as with PCE, the 

CalEPA values are acceptable as the most recent data from an approved tertiary source of reference data 

according to the Cook memo. 

-1 -1 The CalEPA provisional toxicity values are: CSFO = 0.013 (mg/kg-day) ; CSFI = 0.007 (mg/kg-day) ; 3 3 3 Chronic Inhalation REL = 600 (mg/m ) thus, RfC = 0.600 (mg/m ), RfD is 0.600 times 20 (m /day) I

divided by 70 kg = 0.17 (mg/kg-day). 

The only existing RfDO is 0.006 (mg/kg-day) originally provided by NCEA. The 2001 document with the 

new CSF also includes a new RfDO which is also under review. The DRAS will use the provisional 

external review draft RfDO of 3.0E-04 (mg/kg day) as the default value.

Because CalEPA has developed an oral cancer slope, the CalEPA value can be used in place of the 

HEAST value. 

The CalEPA CSFO is 250 (mg/kg-day) -1. 

Ethyl methanesulfonate 

It would be acceptable to use the listed HEAST value. However, we could not find this value in the 1997 

HEAST table. 

3-Methylcholanthrene 

Because CalEPA has developed an oral cancer slope, the CalEPA value can be used in place of the 

HEAST value. 

The CalEPA CSFO is 22 (mg/kg-day) -1. 

4-Nitrophenol 

We could not verify any useable toxicity factors including from HEAST or CalEPA. The original source 

listed in DRAS as a reference, the 1997 Region 3 RBCs, no longer lists this COC. This constituent should 

become “factorless.” 

N-Nitrosopiperidine 

We could not verify any toxicity factors in IRIS or HEAST.
 

Because CalEPA has developed an oral cancer slope, the CalEPA value can be used.
 

The CalEPA CSFO is 9.4 (mg/kg-day) -1.
 

Tris(dibromopropyl)phosphate 

We could not verify any toxicity factors in IRIS or HEAST.
 

Because CalEPA has developed an oral cancer slope, the CalEPA value can be used.
 

The CalEPA CSFO is 2.3 (mg/kg-day) -1.
 

New Toxicity Data - Subsequent to the R9 PRG 2004 Review 

IRIS and PPRTV were checked to ensure that any changes or updates subsequent to the 2004 R9 PRG 

review are included in DRAS. The following updates were included: 

A-1-28

Appendix A-1 October 2008 

Ethylene Dibromide CASRN 106-93-4 

The toxicity factors currently available in IRIS are: 

CSFO = 2 (mg/kg-day) -1 

3 -1 IUR = 0.006 (ug/m ) 

Therefore, the DRAS CSF should be 2.1 (mg/kg-day) -1. 

RfDO = 0.009 (mg/kg-day) 

I

3 RfC = 0.009 (mg/m )

Therefore, the DRAS RfD should be 0.0026 (mg/kg-day). I

Toluene CASRN 108-88-3 

The revised toxicity factors currently available in IRIS are: 

RfDO = 0.08 (mg/kg-day) 3 RfC = 5 (mg/m )

Therefore, the DRAS RfD should be 1.4286 (mg/kg-day). I

Barium CASRN 7440-39-3 

The revised toxicity factor currently available in IRIS is: 

RfDO = 0.2 (mg/kg-day).
