** Note: This tank was inadvertently not analyzed prior to use. 

However, hydrocarbon profiles were obtained during use. These 

results are included on the following pages. Animal exposures 

began on May 23, 2001, so chamber hydrocarbon 

characterization began on that date.

METHOD 

Test Substance Identification, Source, and Storage

Gasoline MTBE Vapor Condensate (GMVC; Lot Number API 00-02) was prepared and 

supplied in 420-pound and 20-pound gas cylinders by Chevron Research and Technology Center 

(CRTC; Richmond, CA). Original characterization of the test substance was performed by 

CRTC. The reference gas chromatographic profile of the 19 key components was provided by 

ExxonMobil Biomedical Sciences, Inc. (EMBSI), Annandale, NJ. Twenty-pound cylinders and 

some 420-pound cylinders were stored at ambient temperature in a storage building dedicated for 

that purpose at the Lovelace Respiratory Research Institute (LRRI). The remaining 420-pound 

cylinders were stored in an outside, controlled area at ambient temperature. The test substance 

was transferred, as needed, from the 420-pound to the 20-pound cylinders. Only authorized 

personnel were allowed access to the test substance. Receipt, use, and inventory of this test 

substance were documented. 

Analysis. Before dispensing GMVC from each 420 pound tank, a liquid sample was transferred 

from the 420-pound tank to a small glass vial with a crimp top. A 50 μL sample of liquid was 

injected into a Tedlar bag for gas chromatographic analysis at LRRI. The analytical method is

Exposure System

The exposure system consisted of four level [low, mid, and high target concentration 

levels and control (air only)] H-2000 whole-body chambers [Lab Products, Inc., Seaford, DE], 

the vapor generation system, and the on-line gas analysis system [Miran infrared spectrometers]. 

Figure E-1 is a schematic representation of a typical H-2000 chamber in the exposure system.

was housed in a separate room for safety requirements. Room 408 was modified to meet 

National Fire Protection Association (NFPA) requirements for class I liquids. Electrical 

equipment was excluded from use in room 408, so the Miran 1A infrared spectrometers used for 

analyzing the chamber atmospheres and other electrical equipment were operated in a separate 

room.

H-2000 Whole-Body Chambers. The rats were housed 24 hours per day during quarantine and 

exposure in the H-2000 whole-body inhalation chambers (Figure E-1). Rats were exposed 6 

hours/day (plus 14 minutes, the time for the vapor concentration to reach T90), 5 days/week for 

104 weeks (520 exposure days). Initially, all rats were housed separately in 3.8-inch wide by 

11-inch long by 8-inch high compartments within stainless steel baskets. When male rats 

reached 400 g they were transferred to baskets with 5.7-inch by 11-inch by 8-inch compartments. 

Each chamber contained six baskets. 

The chambers and cage racks were washed weekly. The cage racks were rotated 

clockwise weekly when the rats were transferred from the dirty to the clean chamber. 

The chambers were held at approximately 1 inch of water negative pressure with respect 

to the exposure room, and the chamber flow rates were maintained at 12 to 15 air changes per 

hour (400–500 liters per minute [LPM]). Chamber temperatures were maintained at 20° to 24°C. 

Temperature, relative humidity, and chamber air flow rates were continuously monitored 24

hours per day. Values for the three parameters were recorded at 30-minute intervals by a 

computer-based monitoring system. Oxygen concentration in the chambers was maintained at 

19%. This parameter was checked daily but not recorded. 

A 12-hour light cycle was maintained with lights on at 0600. Light levels in the exposure 

room and noise levels in the chambers were determined periodically. 

Vapor Generation System. A schematic of the vapor generation system is shown in Figure E-3. 

The daily supply of GMVC for each exposure chamber was contained in 20-pound gas storage 

cylinders. Exposure atmospheres were generated by controlling the flow of pressurized GMVC 

through a rotameter, into a heated stainless steel transfer line where the GMVC was completely 

vaporized. Chamber concentrations were controlled by adjusting the flow rates of the GMVC 

and dilution air rate. Chamber exhaust was carried to a thermal oxidizer on the roof of the 

exposure facility where it was burned. 

On-line Gas Analysis System. Chamber atmospheres were monitored continuously by Miran 1A 

infrared spectrometers (Foxboro Wilks, Foxboro, CT). The high-, mid-, and low-level exposure 

chambers were each monitored with their own analyzer. The analyzers for the high-, mid-, and 

low-level chambers underwent weekly five-point calibrations and daily one-point calibration 

checks using test substance. A fourth analyzer was devoted to monitoring the control chamber, 

the room air, and the hood enclosing the 20-pound tank of test substance. This Miran underwent 

a three-point calibration periodically. The Miran 1A analyzers dedicated to the mid- and highlevel chambers were calibrated over a range of 6–35 g/m3

. The Miran 1A analyzers for the 

control chamber and the low-level chamber were calibrated over a concentration range of 

1–7 g/m3

. 

The absorbance signals, recorded continuously from the first 2 hours, second 2 hours, and 

third 2 hours, were averaged to provide three concentration values for each chamber each 

exposure day. The mean of the three values from each exposure chamber was reported as the 

day’s exposure concentration for that chamber.

Qualitative Assessment of Exposure Atmospheres. The qualitative composition of the exposure 

atmosphere in each chamber was determined weekly by gas chromatography using a Shimadzu 

Model GC-17A/FID (Columbia, MD). Exposure atmosphere samples were collected from the 

chambers into Tedlar sampling bags each week. The atmosphere samples were transferred from 

the sampling bags directly to the sampling loop of the GC. The percent peak area of each of 19 

components was compared to the EMBSI hydrocarbon profile.

Qualitative Analysis of the Hydrocarbon Composition of the Test Substance and Exposure 

Atmosphere by Gas Chromatography

The hydrocarbon profile of the test substance and the exposure atmosphere was 

determined using a Shimadzu Model GC-17A/FID (Columbia, MD) equipped with a Petrocol 

DH150 capillary column (Supelco, 150 m × 0.25 mm ID, 1.0 μm film thickness). The 

chromatographic method was adapted from that used by EMBSI and is summarized in Table 

E-1. To validate the system before the exposures began, the retention times and relative peak 

intensities of 19 standards of the 19 major components in the test substance were determined. 

Each standard vapor was prepared in the concentration expected in the test substance as 

determined by EMBSI (see Appendix B) and injected on the GC. These standards and their 

relative peak intensities as expected in GMVC are listed in Table E-2. The gas chromatographic 

profile of the 19 major peaks (retention time and relative peak area) was compared with that 

originally determined for the GMVC by EMBSI and subsequently used as the benchmark for 

comparison of the profiles obtained on test substance and exposure atmosphere samples. 

Two types of performance checks on the gas chromatograph were conducted during the 

study. Each week during the study, the retention times of eight representative components were 

determined using a certified mixture containing 760 ppm butane, 2270 ppm isopentane, 160 ppm 

trans-2-pentene, 430 ppm 2-methylpentane, 220 ppm hexane, 90 ppm 2,4-dimethylpentane, 

100 ppm 2-methylhexane, and 220 ppm isooctane in nitrogen (Matheson Tri-Gas, Irving TX). In 

addition, one-point performance qualifications were performed on each day in which chamber 

profiles were analyzed. The one-point check was performed using a certified standard of 840 

ppm butane in N2 (Matheson Tri-Gas, Irving, TX).

Computer Environmental Monitoring System

A general layout of the Computer Environmental Monitoring System (CEMS) is shown 

in Figure E-4. The system is comprised of a computer, LabVIEW data acquisition software, 

input/output (I/O) hardware, transducers, and instruments. LabVIEW serves as the interface 

between the operator and the monitoring system. The computer executes the LabVIEW 

monitoring program and performs data acquisition, data storage, and directs communications via 

data acquisition, serial interface, and signal conditioning hardware. LabVIEW (version 6.0, 

National Instruments Corporation, Austin, TX) is a software program that was used to develop 

the automation, control, and monitoring application for this study. The LabVIEW application 

(“Gas Condensate CEMS”) acquires the signals from the exposure system transducers via I/O 

hardware that converts the transducer signals to voltage measurements. The LabVIEW 

application then converts the voltage measurements to physical parameters (i.e., temperature, 

pressure, flow, RH).

Chamber and room temperatures were measured using calibrated series 400 thermistor 

probes (Omega Engineering, Stamford, CN), chamber humidities were measured by model 

5103VHH calibrated RH sensors (Thermalogic, Hudson, MA), and pressures measured by series 

PX41 and PX163 calibrated pressure transducers (Omega Engineering, Stamford, CN). Flows 

were calculated from pressure differential measurements across 2-inch orifice meters. The 

acquired parameters were summarized by the LabVIEW application in a summary data file each 

day, and the mean, minimum, maximum, and standard deviation of each environmental 

parameter is written to the file every 30 minutes. The LabVIEW application also is used to start 

and stop the exposures and to record average vapor concentrations every 2 hours to a data file.

RESULTS 

Pre-exposure Characterization

The exposure system was tested prior to animal exposures. Characterization included the 

following: 1) within-day and between-day consistency of the hydrocarbon profile as determined 

by gas chromatography; 2) uniformity of the distribution of total vapor within each chamber; 

3) determination of the time for vapor concentration to achieve 90% of the equilibrium target 

value (T90); and 4) the exposure atmosphere in the animals’ breathing zone was also examined 

for the presence of aerosol particles using a TSI Scanning Mobility Particle Sizer (TSI Industries, 

Shoreview, MN). One time, prior to the initiation of animal exposures, the concentration of the 

test substance in the generator containment hood and in the exposure room were measured to 

ensure that the generator containment hood was operating satisfactorily. 

Three-Day Stability Evaluation and Nominal GMVC Usage. Before exposures were initiated the 

system was operated for 6 hours/day for 3 consecutive days to determine system stability. The 

concentration of vapor in each chamber was close to target and constant within each day, and the 

concentrations were reproducible from day to day (Table E-3). Gas chromatographic analysis of 

the chamber atmospheres indicated that the relative percentages of the major components were 

constant over the 3-day period. The percentages of actual GMVC usage/anticipated usage 

(nominal usage) on the 3 days of stability testing were 95, 97, and 90 for Days 1, 2, and 3, 

respectively.

Homogeneity of Vapor Concentration. The homogeneity of vapor concentration throughout the 

exposure chambers was determined by conducting a chamber distribution study. The 

concentrations of GMVC were measured from four sampling ports located in front and four 

sampling ports located in the back of the chambers during an exposure day and compared to the 
Study Number FY01-013

concentration obtained in a reference location within the chamber. The spatial variations 

measured in Chambers 6 (2 g/m3

), 7 (10 g/m3), and 8 (20 g/m3) were 3.0%, 1.3%, and 0.8%, 

respectively. These results indicate the vapor was distributed evenly within each of the 

chambers. 

T90 Determination. The amounts of time required to reach T90 were 13, 14.1, and 14.2 minutes 

for Chambers 6, 7, and 8, respectively. A T90 of 14 minutes was chosen for use with this study. 

Daily exposures periods to GMVC were then 6 hours and 14 minutes. 

Confirmation of the Absence of Aerosols. The particle concentrations of air inside Chamber 8, 

operated at a target concentration 20 g GMVC/m3

, and the control chamber (Chamber 5) were 

determined using a TSI Aerodynamic Particle Sizer (model 3321, TSI, Inc., St. Paul, MN). 

There was less than 1 particle per cubic centimeter air in the control and high-level chambers, 

indicating that there were no GMVC aerosols at the highest target vapor concentration used in 

this study. 

In-Study Data

Test Substance. The composition of the test substance remained acceptably constant throughout 

the study. Results of gas chromatography analyses of the test substance are provided in 

Appendix B. 

Chamber Distribution Evaluation During Exposures. During the second week of exposures, the 

uniformity of vapor distribution was re-evaluated to determine the distribution in the presence of 

the test animals. The spatial variations measured in Chambers 6 (low-level chamber, 2 g/m3

), 7 

(mid-level chamber, 10 g/m3

), and 8 (high-level chamber, 20 g/m3) were 2.8%, 0.86%, and 1.8%, 

respectively. These results indicated the vapor was distributed evenly within each of the 

chambers. 

Determination of Nominal Concentration. Daily nominal or “anticipated” usage was calculated 

by multiplying the average GMVC concentration in each chamber (low, mid, high; g/m3) by the 

total flow through each respective chamber ([L/min * min]/[1000 L/m3]) and then summing the 

values for all three chambers. This value was compared to the actual GMVC usage determined 

by taking the difference between the weight of the 20-pound cylinder before and after each 

exposure.

Concentration of Test Substance in the Exposure Room. Concentration of the test substance in 

the exposure room was determined periodically during the study (at approximately 60-day 

intervals) using a Miran 1A Infrared Spectrometer (Foxboro Wilks, Foxboro, CT) operated using 

the same settings as used to monitor the low-level exposure chamber. 

Chamber Concentrations and Nominal Usage. The overall study means of the daily vapor 

concentrations achieved for the 2, 10, and 20 g GMVC/m3

 vapors are provided in Table E-4. 

The overall achieved means were within 2% of target for each exposure concentration. Thus, all 

future references to exposure concentration are in terms of target concentration. For the control 

chambers, concentrations of “zero” were obtained on all but 15 of the 520 exposure days. On 

these 15 days, the readings were below the lowest concentration on the standard curve used to 

calibrate the control chamber Miran 1A (1 g GMVC/m3

). Daily results are provided in Appendix 

E-5. Concentrations of GMVC in room air were below the concentration of the lowest standard 

used to calibrate the Miran 1A (1 g/m3; Appendix E-6).

). 

The overall average of the daily percent nominal usage was 99% ± 4%, indicating 

excellent agreement between anticipated and actual GMVC usage. 

Gas Chromatographic Profiles of GMVC Exposure Atmospheres

Gas chromatographic profiles were obtained from each exposure chamber weekly to 

assess whether the animals were exposed to the relative amounts of the same 19 major 

components throughout the study. The peak areas of the 19 major components were summed to

divided by the total peak area for the components to obtain a relative peak area (in percent) for 

each of the components. These were compared to the reference values provided by EMBSI. 

Profiles remained acceptably constant throughout the study. Results are provided in Appendix F.

INTRODUCTION

Groups of 50 male/50 female CDF(F344)CrlBR rats were exposed in H2000 whole-body 

inhalation chambers at GMVC vapor concentrations of 2 g/m3

 (low level), 10 g/m3 (mid level), 

and 20 g/m3

 (high level) 6 hours/day, 5 days/week for 104 weeks (520 exposure days). There 

was also a control group (0 g/m3). Blood was collected after approximately 12 and 18 months 

and at terminal sacrifice for evaluation of total and differential white blood cell counts. Animals 

surviving 104 weeks underwent a final sacrifice. Statistical evaluations were performed for the 

following endpoints: 

a. Survival as a function of sex and dose group 

b. White blood cell count (estimate) and differential white blood cell counts 

c. Histopathological lesions 

METHODS 

Survival Analysis

The number of days of survival was calculated for each animal in the study. Two female 

rats who died subsequent to accidental nose injuries early in the study were deleted from the 

analysis. The probability of survival was estimated by the Kaplan-Meier product-limit method 

using PROC LIFETEST in SAS Version 8.2. Mean numbers of survival days and time to 25% 

mortality were estimated for each dose group. Log-rank tests were used to test the hypothesis 

that there are differences among the four groups for each sex. The significance level was set at 

p = 0.05. All reported p-values for the survival analysis are two sided. 

Analysis of White Blood Cell Total and Differential Cell Counts

For the hematology data, medians and ranges are presented because the distributions are 

highly skewed for some variables. Preliminary analyses were done using the generalized 

estimating equation approach for longitudinal data analysis because there were three time points. 

For some variables these analyses showed significant interactions between time and group. 

Therefore, analyses were done to compare dose groups at each time point and to compare time 

points within each dose group. The Krusal-Wallis test was used for these comparisons. 

Analysis of the Incidences of Microscopic Lesions

The incidences of all neoplastic and non-neoplastic lesions are given as the ratio of the 

number of affected animals to the number of animals with the site examined microscopically. 
Study Number FY01-013

O-4 

Three statistical evaluations were performed on the histopathology lesion incidence data: 

1) Cochran-Armitage test, which tests whether the incidence of lesions shows a trend across dose 

groups; 2) logistic regression that takes death date into account when assessing the presence of a 

dose-dependent trend; and 3) the Fisher’s exact test to compare incidences among the four dose 

groups. The two-sided significance level was set at p = 0.05. If a significant difference was 

detected by the Fisher’s test, six possible pairwise comparisons were calculated. Using the 

Bonferroni correction for pairwise comparisons, each pairwise comparison would be considered 

significant if p < 0.008. 

Fisher’s exact test and the Cochran-Armitage test do not use survival information and are 

appropriate in situations where survival is similar among exposure group as is the case for this 

study. The Fisher’s exact tests the null hypothesis of equality of prevalences across dose groups 

against the alternate hypothesis that the prevalences are not equal, while the Cochran-Armitage 

tests the null hypothesis of equality across doses against the alternate hypothesis of a monotonic 

increasing or decreasing trend. The difference in these hypothesis tests can be seen in the test of 

“degeneration, cytoplasmic vacuolization” for female adrenal glands. The incidences are 24%, 

5%, 0%, and 28% for 0 g/m3, 2 g/m3, 10 g/m3, and 20 g/m3, respectively. The p-value for the 

Fisher’s exact test is 0.006, indicating differences among the incidences. However, the p-value 

for the Cochran-Armitage test is 0.73, indicating no detectable upward or downward trend across 

the doses. 

RESULTS 

Survival

All groups had 50 animals except the mid-level group for females. Two animals in that 

group were omitted from the analysis because of nose injuries. Figures O-1 and O-2 show the 

survival curves for male and female animals, respectively. The differences among the groups are 

not statistically significant for male (p = 0.46) or female animals (p = 0.07). Table O-1 shows 

means, standard errors, and day of 25% mortality for male and female animals under each 

experimental condition. For the calculation of mean and standard errors of survival times, the 

last day of the study was used as the value of the survival time for animals that were sacrificed at 

the time that the study was terminated. Therefore, the means and standard errors may be 

underestimated because some of the animals may have lived longer if the protocol had included 

following them for a longer period of time. The results indicate that chronic GMVC inhalation 

did not shorten the lifespan of the exposed rats compared to the controls.

Analysis of White Blood Cell Total and Differential Cell Counts

Results for female and male rats are provided in Tables O-2 and O-3, respectively. In 

many cases there were differences in cell numbers over time, but the differences in control and 

high-level animals were in the same direction. Significant differences between exposed and 

control groups occurred primarily in males at the 12-month sampling time. 

Analysis of the Incidences of Microscopic Lesions

Results of analyses on microscopic lesions for female and male rats are provided in 

Tables O-4 and O-5, respectively. Significant trends with increasing GMVC exposure 

concentration were detected in some cases. Incidences of lesions did not always increase with 

increasing concentration. In several cases, although a difference was detected by the Fisher’s 

test, the lesion incidences were not concentration dependent, leading to a lack of similarity 

between the results obtained using the Fisher’s test and results using the Cochran-Armitage test 

and logistic regression. Interpretation of the significance of these differences is provided in the 

main report text and in the Pathologist’s Report (Appendix P).

Gasoline MTBE Vapor Condensate (GMVC) 

P-3 

INTRODUCTION 

Four hundred (400) F344 rats exposed to gasoline MTBE vapor condensate (GMVC) in 

whole body inhalation exposure chambers were examined. Males and females were divided 

equally into 4 groups (50 males and 50 females per group) and exposed to 0 g/m3, 2 g/m3, 

10 g/m3 or 20 g/m3 GMVC for 6 hours/day, 5 days/week for 104 weeks (520 exposure days). 

The sole scheduled sacrifice occurred after 104 weeks (520 days) of exposure. Gross necropsy 

and tissue collection was performed as specified in the main report text. 

METHODS 

Hematology

Blood was collected on control and high-level GMVC rats by tail nick at 12 and 18 

months of exposure and was collected from all final sacrifice rats by cardiac puncture for 

assessment of total and differential white blood cell counts. Duplicate blood smears were 

prepared and read manually for the control and high-level groups at all three time points. 

Percentages of each nucleated cell type were counted. An estimate of the number of white blood 

cells in each sample was made according to LRRI SOP. Absolute numbers of each cell type 

were calculated by multiplying the fraction of each cell type by the estimated white blood cell 

count. 

Gross Pathology

As expected in a chronic study, a wide spectrum of gross lesions was documented at 

necropsy. Complete gross lesion incidences as well as correlation of gross and histologic lesions 

are located in Appendix M (males) and N (females). Gross lesions were examined histologically 

in all groups. 

Histopathology

All study animals received a complete necropsy. Animals were euthanized with an 

overdose of intraperitoneally injected barbiturate anesthetic (Euthasol®, Virbac AH Inc., Fort 

Worth, TX). Body weights and fresh organ weights were collected on lungs, liver, kidneys, 

adrenals, testes, epididymides, ovaries, uterus, spleen, brain and heart of final sacrifice and 

moribund sacrifice animals. Animals found dead received a complete necropsy with tissue 

collection, but blood and organ weight data were not routinely collected. Cardiac blood was 

collected from animals at final sacrifice for determination of total and differential white blood

cell counts. Gross lesions, body weights, and organ weights were entered on pre-prepared forms 

and then the information was recorded on the Path-Tox database (Version 4.2.2, Module P, 

Xybion Medical Systems, Cedar Knolls, NJ). 

Lungs were gently instilled via the trachea with 10% neutral buffered formalin (NBF) to 

approximate normal volume. Organs/tissues were immersion fixed in 10% NBF for subsequent 

histopathologic examination. Tissues were trimmed, processed routinely, paraffin embedded, 

sectioned at 5 μm and stained with hematoxylin and eosin for histopathologic examination. 

All collected tissues and lesions were examined histologically in control (0 g/m3

) 

animals, high- (20 g/m3

) level animals, and dead or moribund animals of all groups. Respiratory 

tissues (lungs, larynx, trachea and nasal turbinate sections), potential target tissues (testes, 

kidneys of males) and gross lesions were examined histologically from final sacrifice low- (2 

g/m3

) and mid- (10 g/m3) level animals. Nomenclature of proliferative lesions was based on the 

international harmonized nomenclature recommended by the Rat Nomenclature Reconciliation 

Subcommittee of the Society of Toxicologic Pathologists (see http://www.toxpath.org; 

Standardized Rat Nomenclature). Nomenclature of other lesions was routine, widely understood 

usage (see Boorman et al., 1990a; Gopinath et al., 1987). 

Standard, subjective severity scoring of most nonproliferative lesions was based on the 

extent of tissue affected by the change and the severity of the change within affected areas. 

Typically, a score of 0 (none) = essentially no tissue affected; 1 (minimal) = ~1 to 10% affected, 

2 (mild) = ~11 to 25% affected, 3 (moderate) = ~26 to 50% affected, 4 (marked) = ~51 to 100% 

affected. Severity scores may have been adjusted up or down (usually by 1 point) based on the 

intensity of the change within the affected areas. 

Because the diagnosis of chronic progressive nephropathy encompasses a large 

constellation of changes, severity scoring for this diagnosis was somewhat more complex and is 

described in Table P-1. 

Statistical Analyses

Statistical analyses of both hematology and histopathology data were conducted as 

detailed in the statistician’s report (Appendix O). In the case of renal tubule nephropathy and 

nasal epithelial degeneration, statistical evaluation of group differences in severity scores was

performed using the Kolmogorov-Smirnov test within the Path-Tox software (significance level 

p = 0.05; c.f. Algorithms used in Path/Tox System 4.2.2; Vol. I, Chap. 7, pp. 24-25). 

Table P-1. Severity Scoring of Chronic Progressive Nephropathy 

Score Histologic Findings 

0 Essentially no changes of CPN. May have rare scattered protein casts in tubules, 

mineral concretions. 

1 Increased number and size of tubular protein casts; primarily within tubules at the 

corticomedullary junction, some within collecting ducts. Minor/scattered foci of 

basophilic, regenerative tubules. Changes affect less than ~5% of tissue component. 

2 Homogeneous protein casts relatively abundant within tubules and collecting ducts 

(especially at corticomedullary junction). Increased size and frequency of tubular 

basophilia. Accompanying changes present, may include small foci of tubular basement 

membrane thickening and/or mineralization, interstitial fibrosis, tubular atrophy and 

dilatation, minor associated mononuclear inflammatory infiltrates, glomerular changes 

(including mesangial proliferation, synechiae, proliferation of parietal epithelium). 

Changes may affect up to ~25% of component. 

3 As 2 with increased tubular atrophy/dilatation/regeneration, interstitial fibrosis, 

increased inflammatory infiltrates, increased thickening of basement membranes of 

tubules and glomeruli. 

4 As 3 with increased severity and extent of changes. Senescent glomeruli relatively 

common. Typically combined changes affect well over 50% of kidney. 

RESULTS 

Hematology

The high incidence of leukemia in aged F344 rats, other physiologic changes with aging, 

sampling differences between time points and the limitations of manual hematology (e.g., the 

small numbers of leukocytes other than neutrophils and lymphocytes counted) dictate that the 

hematology results be interpreted with caution. Trend tests within a group across all sampling 

periods frequently show a statistical difference, but are not expected to be biologically significant 

for the reasons noted above (some specific examples follow). A statistically significant increase 

relative to controls in WBC estimate, “absolute” neutrophils, and “absolute” lymphocytes was 

noted in high-level group males at 12 months. This change is not present in females and does 

not persist in males at 18 or 24 months. It is interpreted as an excitement response probably 

resulting from initial blood sampling difficulties. The increase in atypical lymphocytes in both 

the control and the high-level group at 24 months is consistent with the high incidence of

P-6 

leukemia in these aged F344 rats. Other statistically significant changes are unlikely to be 

biologically significant based on the small numbers of leukocytes of that type (such as band 

neutrophils, monocytes or eosinophils) counted in blood smears. 

Histopathology

Condensed tables including only microscopic lesions judged to be more relevant as 

potential effects of GMVC exposure or those for which reviewers indicated an interest are 

presented below. Note that all microscopic findings are not included here; refer to the summary 

tables in Appendices M and N for a complete listing. Though some comparisons are included 

here, see GMVC main report for more complete comparison between findings from this study 

and the Baseline Gasoline Vapor Condensate (BGVC) study run concurrently. 

Proliferative Lesions. Proliferative lesions include hyperplasias and neoplasias (both benign and 

malignant). As is evident in the complete lesion incidence summary tables (Appendices M and 

N), scattered hyperplasias and neoplasias occur relatively commonly in aged F344 male and 

female rats. 

Male rats in the mid-level GMVC group demonstrated a significant increase in the 

incidence of renal tubule cell adenomas in mid-dose animals, with 0/50 (0%), 0/50 (0%), 6/50 

(12%) and 2/50 (4%) in the control, low, mid and high groups, respectively (Table P-2). 

Although not statistically significant alone, there was also an increase in renal tubule carcinomas 

in the males (1/50; 2% in low- and 1/50; 2% in high-level males). Combining adenomas and 

carcinomas for analysis maintained the statistically significant increase in tumors in mid-dose 

animals, and additionally showed a significant trend toward increased incidence with increased 

exposure concentration (Table P-2). 

Squamous cell carcinoma occurred in nasal sections of males with an animal incidence 

(incidence of tumor occurring in any of turbinates 2–4) of 1/50 (2%), 2/50 (4%), 0/50 (0%) and 

2/50 (4%) for control, low-, mid- and high-dose animals, respectively, with no statistically 

significant differences or trends. In all instances, the tumors were judged to have arisen in the 

oral cavity (Appendix M-6). Animal incidence is relevant because the same tumor may occur in 

more than one nasal section. This is true for the low- and high-level groups for male nasal 

turbinates 3 and 4 (Table P-2), where one animal in each group has a tumor spanning levels 3 

and 4.

211(b) Chronic Carcinogenicity Study 

Gasoline MTBE Vapor Condensate (GMVC) 

P-7 

No significant changes in incidence were seen for thyroid follicular cell adenoma or 

carcinoma. Combining thyroid follicular cell adenoma and carcinoma in male rats gave a 

combined incidence of 3/50 (6%), 0/35 (0%), 1/31 (3%) and 5/50 (10%) for control, low-, midand high-level groups, respectively. No statistical signficance was found upon combining the 

incidinces of adenomas and carcinomas. Note that one high-dose male had both an adenoma and 

a carcinoma, yielding a combined incidence of 5/50 (10%). However, even when counting 

adenoma and carcinoma in this animal individually, yielding an incidence 6/50 (12%) for this 

group (arguably the most conservative combined incidence from a risk assessment perspective) 

the difference is not significant using Fisher’s exact test; p = 0.130. See e-mail correspondence 

from statistician including statistical test in study file). A statistically significant increase in 

thyroid follicular cell carcinomas (but not combined adenomas and carcinomas) was observed 

among males in the Baseline Gasoline Vapor Condensate study run concurrently (FY01-027). 

As expected, there was a high background incidence of testicular interstitial adenomas in 

control male rats (43/50; 86%). There was a significant trend toward increased incidence with 

increased dose (with 47/50; 94% in lows and 48/50; 96% in mids), and the incidence among 

high-level males (50/50; 100%) was significantly greater than the control incidence (Table P-2). 

Essentially all testes with adenomas had foci of hyperplasia when the testis was not entirely 

effaced by tumors. However, the frequent effacement of testicular parenchyma by tumors in this 

chronic study renders the diagnosis of hyperplasia in testes with tumors of little or no value. 

Thus interstitial cell hyperplasia was recorded primarily in testes without tumors (see Appendix 

M). 

Mesothelioma was present at a relatively low incidence of 0/50 (0%), 1/50 (2%), 1/50 

(2%) and 2/50 (4%) for control, low-, mid- and high-level groups, respectively, and no statistical 

differences were noted for this neoplasm. Incidences in this study were comparable to the 

historical incidences for NTP studies (0–10% with a mean of ~3% [Haseman et al., 1998]). 

Results are somewhat different from those obtained in the Baseline Gasoline Vapor Condensate 

study, were a significant trend toward increased mesothelioma was noted (Fisher’s Exact test). It 

should be noted that no testicular mesotheliomas were present in control animals in this or in the 

Baseline Gasoline Vapor Condensate study.

Trend detected with Fisher’s Exact test. 

In males, mononuclear leukemia in the spleen demonstrated statistically significant 

increases in low and mid versus control group, these are judged unlikely to be a result of GMVC 

exposure (see Table P-5 and Discussion). 

Female rats had relatively similar incidences of mononuclear leukemia and across groups. 

Mammary fibroadenomas were significantly increased in low and high animals, but a 

surprisingly low incidence in controls complicates the interpretation (see Table P-6, Discussion, 

Appendices M and N). 

Nonproliferative Lesions. Nonproliferative lesions include degenerative and inflammatory 

changes. Such changes are common in many tissues in aged F344 male and female rats, and 

their significance in older animals must be interpreted with caution. 

Kidneys of male rats exposed to GMVC had significant increases in severity, but not 

incidence of chronic progressive nephropathy and both mid- and high-level males (Table P-3). 

Mid- and high-level males also demonstrated a significant increase in incidence (but not

Lesions Showing Statistical Significance, but Judged Not Likely Due to GMVC Exposure

Other proliferative and nonproliferative lesions occurred which were not clearly 

significant or were judged to have confounding factors which must be considered in 

interpretation. For completeness, these lesions are listed for males (Table P-5) and females 

(Table P-6). Some findings were decreased in exposed animals compared to controls, these are 

not generally discussed. 

Some general notes are warranted: 

1) A number of diagnoses which appear as statistically significant are confounded by 

the fact that the tissues were only examined if grossly abnormal. This is 

particularly true in low- and mid-level animals. For example, liver and uterus were 

examined histologically in low- and mid-level animals only if a gross lesion was 

detected. Thus, the incidence of “leukemia, monocytic” and “polyp, endometrial 

stromal” was skewed upward by a protocol driven sampling bias. For the purpose 

of comments in the tables below, this will be termed “gross lesion sampling bias.” 

2) The incidence data for the diagnosis of “leukemia, mononuclear” should be 

considered only for the spleen. This is typically accepted as the tissue of origin of 

this hematopoietic neoplasm (also termed large granular lymphocytic leukemia,

Fischer rat leukemia, monocytic leukemia, etc.) in F344 rats, and the lesion was 

called in the spleen any time it occurred in other tissues. Incidence data for this 

diagnosis in other organs are often spurious because some tissues were examined 

only if abnormal. This is particularly true in low- and mid-level group animals 

which had a more limited routine tissue set (“gross lesion sampling bias”).

DISCUSSION 

Proliferative Lesions

Benign tumors of the kidney and testes in males are the proliferative lesions documented 

most clearly in rats exposed via inhalation to GMVC in this study. 

Adenomas of renal tubule epithelial cells are relatively uncommon background lesions in 

F344 rats, with an average incidence in males of 1.0% (range 0–4%) in NTP study controls 

(Haseman et al., 1998). The lack of a typical exposure concentration response in this study is 

difficult to resolve, but the significantly increased incidence in mid- (12%) and increased 

incidence in high- (4%) level males is presumed to have resulted from GMVC exposure. 

Additionally there was a low incidence of renal tubule carcinoma in low- (2%) and high- (2%) 

level males which was not statistically different from controls. Combining adenomas and 

carcinomas for analysis (controls 0%, low 2%, mid 10% and high 6%) maintained the significant 

increase in tumors in the mid-dose group and yielded a significant positive exposure-related 

trend. These results are consistent with findings of an increased incidence of combined renal 

adenomas and carcinomas in the Baseline Gasoline Vapor Condensate Study (FY01-027). 

Given the increased severity of chronic progressive nephropathy in mid- and high-level 

males, a plausible explanation for the increase in renal tubule tumors may be a sustained increase 

in cell turnover/proliferation and subsequent tumor induction via epigenetic mechanisms of 

carcinogenesis in male rats, including damage related to alpha-2u globulin overload (Hard, 1998; 

Baetcke et al., 1991). Previous studies with wholly vaporized gasoline, MTBE, and related 

compounds have also documented increased nephropathy in male rats, and increases in renal 

tubular adenomas and carcinomas (MacFarland et al., 1984; Medinsky et al., 1999; Bird et al., 

1997). Further consideration of the nonproliferative, but potentially relevant lesion of chronic 

progressive nephropathy is presented below and under the “Nonproliferative Lesions” 

discussion. 

The increase in renal tubule adenomas and carcinomas in males may be related to the 

increased severity of chronic progressive nephropathy through a sustained increase in tubule 

epithelial cell turnover, a recognized occurrence in male rats (Hard, 1998). For compounds 

inducing renal tumors in male rats through increased alpha-2u globulin accumulation and 

subsequent increased renal tubule cell turnover, the human health relevance of the mechanism

P-15 

and thus the tumors is often regarded as suspect (Baetcke et al., 1991; Hard, 1998; Hard and 

Khan, 2004). Alpha-2u globulin nephropathy is a plausible mechanism for GMVC related renal 

adenomas and carcinomas based on other MTBE and similar compound study reports (and 

including the results of a 13-week unpublished study on gasoline vapor condensate without 

MTBE conducted at LRRI). In F344 male rats after approximately 1 year of age, alpha-2u 

globulin overload nephropathy may be masked by age-related chronic progressive nephropathy 

(CPN), since both forms of nephropathy share similar if not identical diagnostic hallmarks. The 

effect of alpha-2u globulin overload nephropathy typically manifests itself in increased severity, 

rather than incidence, since essentially all males surviving past 1 year of age will develop CPN. 

Note that GMVC also induced increased severity of nephropathy in females at the highest dose, 

although via a different mechanism since alpha-2u globulin overload is male rat specific. 

Squamous cell carcinomas (SCC) present in nasal sections of males [animal incidences of 

1/50 (2%), 2/50 (4%), 0/50 (0%) and 2/50 (4%)] were judged to be of oral origin in all cases. 

The low incidences and presence of this neoplasm in a control male render any relationship to 

exposure difficult to discern in this study. Historical control incidences of this tumor in NTP 

inhalation studies are low (~0.6%). However, a large study with cigarette smoke conducted at 

this facility in the early 1990’s had an incidence of 0/118 (0%) squamous cell carcinomas of oral 

origin in males and 3/119 (2.5%) in females. No tumors were of nasal origin. While comparison 

between this study and the concurrent BGVC study is largely done in the GMVC main report, 

note that the BGVC study had none of these tumors (0/50) in control males but one (1/50) in 

control females. In the BGVC, there was a trend for significant increase in squamous cell 

carcinomas in males, but no group differences by the Fisher’s Exact Test. Nonetheless, a minor 

but relatively consistent increase in incidence in exposed animals is present in both studies. 

Clearly the whole body method of inhalation exposure has the potential to result in some degree 

of exposure directly to the oral cavity in addition to the systemic exposure from inhalation (from 

grooming, etc.). 

Interstitial (Leydig) cell adenomas of the testes are very common lesions in male F344 

rats, with average reported incidences up to 89% or even 100% in 2-year studies (Haseman et al., 

1998; Boorman et al., 1990c). Incidence of this benign tumor was similarly high in all groups in 

this study as well, but the incidence in high-level males was significantly increased, and an 

exposure concentration response was present. While within this study with GMVC the data

P-16 

suggest a causal relationship between exposure and testicular interstitial adenomas, the 

relationship between treatment with MTBE and induction of testicular interstitial adenomas is on 

the whole more equivocal, since background incidence of this tumor is quite variable and usually 

extremely high [(NTP control incidence for air inhalation controls: for NIH-07 diet avg. = 

70.1% with range of 46% to 90%; for NTP-2000 diet avg. = 92.1% with range of 82% to 98%), 

and control incidence in the concurrently run Baseline Gasoline Vapor Condensate chronic study 

(LRRI study number FY01-027) was 48/50 (96%)]. Other MTBE toxicity studies have 

documented increases in testicular interstitial cell adenomas (Bird et al., 1997; Belpoggi et al., 

1995). However, in a recent review of the mechanisms of MTBE induced carcinogenicity, the 

overall evidence for MTBE induction of testicular interstitial cell adenoma was considered to be 

equivocal (Cruzan et al., 2007). Note that the human health relevance of interstitial cell tumors 

in rats has been called into question suggesting little predictive value for humans (Prentice and 

Meikle, 1995; Cook et al., 1999). 

Leukemia, a well-documented feature of old age in F344 rats, did not appear to be 

enhanced by GMVC exposure. Results for spleen, the defining organ for this disease, are shown 

for males and females in Table P-2. In males, the incidences of leukemia in the low- and midGMVC levels are greater than controls (Fisher’s test). However, there was no overall significant 

trend with exposure concentration as determined by the Cochran-Armitage and logistic tests, and 

the incidence of leukemia in high-level males was not different from controls (Fisher’s test). The 

incidences of leukemia in GMVC-exposed females were similar to or lower than control but not 

significantly different (Table P-2). 

Mammary gland fibroadenoma was significantly increased in low- and high-level females 

(Tables P-2 and P-6). Interpretation of this finding is problematic due to the atypically low 

control incidence of 0% in control females. Control incidences for this lesion have been reported 

to range from 27–40% (Boorman et al., 1990b). The control incidence in the parallel BGVC 

study (LRRI study number FY01-027) was 4/49 (8%). Additionally, increases in this lesion have 

not been observed in previous studies with neat MTBE or wholly vaporized gasoline (Cruzan et 

al., 2007; MacFarland et al., 1984). Therefore, it is judged unlikely that the increased incidence 

in female mammary gland fibroadenoma was treatment-related.

Nonproliferative Lesions

Males. Chronic progressive nephropathy (CPN) is the diagnostic terminology for an entity in 

rats comprised of a constellation of changes commonly affecting the kidneys of F344 rats. 

Lesions in male rats appear earlier and are routinely more severe than those in females 

(Montgomery and Seely, 1990). Renal lesions typically consist of tubular degeneration and 

regeneration, proteinaceous casts, tubular atrophy and dilatation, interstitial fibrosis, basement 

membrane thickening and glomerulosclerosis depending on the severity. The severity scoring 

for this lesion in described in a previous section. 

The increased average severity score for CPN in mid- and high-level males is judged to 

be a consequence of GMVC exposure. It may reflect damage resulting from increased alpha-2u 

globulin associated with hydrocarbon nephropathy (HN). Some classic hallmarks of 

hydrocarbon exposure—including the presence of brightly eosinophilic cytoplasmic droplets 

within tubular epithelium and granular casts/linear mineralization in the outer stripe of the 

medulla—were not apparent even in high-level males (while regions of cytoplasmic eosinophilic 

droplets occurred, they were similar between controls and exposed and not judged representative 

of HN). As discussed below however, the absence of these hallmarks is not unexpected in 

kidneys from aged rats. 

Hyaline droplet or protein accumulation in shorter term MTBE studies is reported 

(Medinsky, 1999; Lington et al., 1997; Bird et al., 1997), but the change is not necessarily noted 

in kidneys from chronic exposures (Bird et al., 1997; Rudo, 1995). It is noteworthy that a 

chronic t-butyl alcohol exposure study conducted by the NTP also lacks a specific diagnosis of 

“hyaline droplet nephropathy,” although such a diagnosis is made during a shorter term (13 

week) exposure study (NTP, 1995). Hyaline droplet accumulation is commonly seen with 

hydrocarbon exposure, and might be expected with GMVC inhalation (Gopinath et al., 1987). 

Such a “hydrocarbon nephropathy” may have occurred as an earlier lesion which was 

masked/obscured in these chronically exposed animals by the progression of CPN. There is also 

some evidence that aged male rats are much less sensitive to hydrocarbon nephropathy and that 

production of the major protein constituent of hyaline droplets, alpha-2u globulin, is greatly 

decreased in old rats (Murty et al., 1988). In addition to renal lesions of hyaline droplet 

formation, increased tubular regeneration/proliferation and CPN have been previously reported

211(b) Chronic Carcinogenicity Study 

Gasoline MTBE Vapor Condensate (GMVC)

in male rats as a result of MTBE and similar compound exposure (Medinsky et al., 1999; 

Lington et al., 1997; Bird et al., 1997; Clary, 1997; Borghoff et al., 2001). 

The human health significance of the chronic progressive nephropathy of male rats 

associated with accumulation of hyaline droplets containing alpha-2u globulin is suspect. It and 

the subsequent development of renal tubule adenomas are often considered male rat specific and 

thus not significant for humans (Greaves, 2000; Baetcke et al., 1991; Hard, 1998) though 

opinions differ (Melnick, 1992). As previously noted, the typical lesions of hyaline droplet 

nephropathy were not documented in this study at the chronic timepoints examined, but this is 

not unexpected since diagnostic hallmarks (primarily linear mineralization) to suggest HN at 

chronic timepoints and with severe overlying CPN are limited. It should be noted that the 

severity of chronic progressive nephropathy was increased in high-level females which are not 

susceptible to typical alpha-2u globulin related nephropathy. This suggests the possibility that 

more than one mechanism may be important in the development of chronic progressive 

nephropathy in response to GMVC. 

Increased hyaline degeneration of nasal epithelium (typically olfactory and respiratory) 

characterized by the accumulation of hyaline droplets/globules is a common, nonspecific finding 

in aged rats and is increased in response to a number of toxicants (Boorman et al., 1990d; 

Gopinath et al., 1987). Mid- and high-level males had significant increases in incidence relative 

to that seen in control animals in nasal section 2, and there was an exposure concentration 

response in turbinate 3 for males. The overall incidence was relatively low, and the severity of 

the lesion ranged from minimal to moderate in most exposure groups. While the lesion is likely 

exposure related, the significance of this common, minor change by itself is uncertain. 

Females. Kidneys of high-level female rats cumulatively demonstrated a slight increase in 

overall severity score of chronic progressive nephropathy. Though the minor severity difference 

renders interpretation less clear than that in males, the increased severity of CPN in high-level 

females is judged to be an effect of GMVC exposure. A lesser severity of CPN is typical in 

female F344 rats compared to males (Montgomery and Seely, 1990). Reports of MTBE effects 

on kidneys in female rats vary. Some do not report significant differences in female renal lesions 

(Lington et al., 1997), others report increased bromodeoxyuridine labeling of tubular epithelium 

or increased CPN incidence and severity (Medinsky et al., 1999; Bird et al., 1997; Clary, 1997).

As noted for the males, hyaline droplet accumulation in olfactory and respiratory nasal 

epithelia is a common, nonspecific response to toxicants in rodents. While the lesion is likely 

exposure related, the significance of this common, minor change by itself is uncertain. 

HISTOPATHOLOGY SUMMARY 

Statistically significant increases in GMVC exposure related lesions were seen in both 

male (kidney, testes, nasal epithelia) and female (kidney, nasal epithelia) F344 rats. Exposure 

related proliferative lesions occurred only in males and consisted of renal tubule adenomas (and 

combined adenomas and carcinomas) and testicular interstitial (Leydig) cell adenomas. The 

increase in renal tubule adenomas was significant only in mid-level group males relative to 

controls (Fisher’s exact test, p ≤ 0.05) and lacked significance using trend tests (CochranArmitage and Logistic tests, p ≤ 0.05). Combining renal tubule adenomas and carcinomas 

maintained the significant increase in mid-level males and also resulted in a significant positive 

trend with increased exposure. Renal tubule neoplasms in rats are influenced by epigenetic 

mechanisms related to CPN and this must be taken into account in this study. Increases in 

testicular interstitial cell adenomas were statistically significant relative to controls in high-level 

animals (Fisher’s exact test, p ≤ 0.05) and as an exposure related trend (both Cochran-Armitage 

and Logistic tests, p ≤ 0.05). As noted in the discussion section, the variable and typically very 

high background incidence of this tumor in aged rats must be considered on the whole in risk 

assessment.

Nonproliferative lesions related to GMVC exposure were present in kidneys (as an 

increase in severity of chronic progressive nephropathy) and nasal epithelia (as hyaline 

degeneration) of both genders. Both mid- and high-level males had significant increases in the 

severity, but not incidence of chronic progressive nephropathy relative to controls (KolmogorovSmirnov test, p ≤ 0.05). The incidence of hyaline degeneration of olfactory epithelium (nasal 

turbinate section 2) was significantly increased in male animals of mid- and high-level groups 

(Fisher’s exact test, p ≤ 0.05), and increased as an exposure related trend (Cochran-Armitage and 

Logistic tests, p ≤ 0.05). An exposure-related trend for olfactory epithelial degeneration was also 

present in turbinate 3 for males. Kidneys of females exposed to GMVC did not have an 

increased incidence (Fisher’s exact test, p ≤ 0.05) or exposure related trend to increased 

incidence (Cochran-Armitage and Logistic tests, p ≤ 0.05) of chronic progressive nephropathy, 

but did demonstrate a significant increase in severity of this lesion in high-level females

(Kolmogorov-Smirnov test, p ≤ 0.05). Nasal cavities of mid- and high-group females had an 

increased incidence of hyaline degeneration of respiratory epithelium (nasal section 2) relative to 

controls (Fisher’s exact test, p ≤ 0.05), and the exposure-related trend for this change was also 

significant (Cochran-Armitage and Logistic tests, p ≤ 0.05). 

Hyaline degeneration of olfactory and respiratory epithelium is characterized by the 

accumulation of homogeneous, hyaline eosinophilic globules. Small numbers of cells with these 

globules are common in aging rodents and in response to toxicants. The significance of the 

minor nasal epithelial changes noted in this study is uncertain.
