ABSTRACT

The developmental toxicity of gasoline with MTBE vapor condensate was
evaluated in 25 confirmed-mated female Crl:CD®(SD)IGSBR rats/exposure
group at target concentrations of 0, 2000, 10,000, and 20,000 mg/m3 in
air.  The animals were exposed daily for six hours from Gestation Day
(GD) 5 through GD 20.  There was evidence of slight maternal toxicity as
indicated by  statistically significant decreases from control in the
20,000 mg/m3 target exposure level for body weight change and food
consumption at the GD 8 - GD 11 interval.  No other statistically
significant differences were noted between the control and treated
groups for the maternal parameters.  There were no statistically
significant differences for uterine implantation data, external, and
visceral observations in the fetuses.  The incidence of dumbbell
vertebral centra was statistically significantly increased in the 10,000
mg/m3 target group. This increase was not considered treatment related
due to the lack of a dose response.  Therefore, the No Observable
Adverse Effect Level for maternal toxicity was established at the 10,000
mg/m3 target exposure level and the No Observable Adverse Effect Level
for developmental toxicity was established at 20,000 mg/m3 target
exposure level.

SUMMARY

This study was conducted to evaluate the potential developmental
toxicity of the test substance, Gasoline with MTBE Vapor Condensate
(GMVC).  GMVC was administered via whole-body inhalation exposure to
pregnant rats during the period of major organogenesis and fetal growth.
 GMVC was administered by whole-body inhalation exposure to 25
confirmed-mated Crl:CD®(SD)IGSBR female rats at target doses of 0 (air
control), 2000, 10,000, and 20,000 mg/m3 for six hours (plus the
theoretical equilibration time) daily from Gestation Day (GD) 5 through
GD 20. The Sponsor selected the exposure levels based upon safety
considerations and previously conducted mammalian toxicity studies.

Clinical observations were made daily during gestation.  Body weight and
food consumption measurements were made on GD 0, 5, 8, 11, 14, 17, 20,
and 21.  On GD 21, animals were sacrificed by CO2 asphyxiation followed
by exsanguination.  The reproductive organs and the abdominal and
thoracic cavities were examined grossly.  Uterine weights with ovaries
attached were recorded.  Uterine contents were examined, and the numbers
of live, dead and resorbed fetuses were recorded.  All fetuses were
weighed, sexed externally, and examined externally for gross
malformations.  Apparent non-gravid uteri were placed in 10% ammonium
sulfide solution for confirmation of non-pregnancy status.

The viscera of approximately one-half of the fetuses of each litter were
examined by fresh dissection.  After these fetuses were examined, they
were decapitated.  The heads were preserved in Bouin's solution for at
least two weeks, rinsed, and subsequently stored in 70% ethanol.  The
fetal heads were sectioned and examined with a dissecting microscope for
the presence of abnormalities.  The remaining fetuses judged to be alive
at the C-section were eviscerated, processed for skeletal staining,
stained for bone and cartilage, and examined for the presence of
skeletal malformations and variations.

There was evidence of maternal toxicity in the 20,000 mg/m3 target
exposure group as indicated by statistically significant decreases in
body weight gain and food consumption for the GD 8-11 interval.  All
dams survived to scheduled terminal sacrifice on GD 21.  At the GD 21
cesarean section one animal in each group was found to be not pregnant
(i.e. no evidence of implantation sites).  All animals were free of
clinical or postmortem effects attributable to treatment with GMVC.

1-1

SUMMARY   (CONT'D)

There were no statistically significant differences between the control
and the GMVC treated groups for uterine implantation data, fetal body
weights, and external, and visceral observations.  The incidence of
dumbbell-shaped vertebral centra was statistically significantly
increased in the 10,000 mg/m3 target group and the incidence was
slightly greater than observed in the historical control data.  However,
this increase was not considered treatment related due to the lack of a
dose response.

In conclusion, administration of the test substance to rats by
whole-body inhalation exposure during the period of organogenesis and
fetal growth resulted in a transient statistically significant decrease
in food consumption and body weight change at the GD 8 - GD 11 interval.
 No other treatment-related observations were evident in the treated
groups that were statistically or biologically significantly different
from the observations in the control group.  

Therefore, the No Observable Adverse Effect Level for maternal toxicity
was established at the 10,000 mg/m3 target exposure level and the No
Adverse Effect level for developmental toxicity was established at
20,000 mg/m3 target exposure level for this study.

INTRODUCTION

This study was conducted to evaluate the developmental toxicity of
Gasoline with MTBE Vapor Condensate (MRD-00-713) administered via
whole-body inhalation exposure to pregnant rats during the period of
major organogenesis and fetal growth.

This study was conducted for the American Petroleum Institute, 1220 L
Street Northwest, Washington, D.C. 20005-4070 (subsequently referred to
as the Sponsor).

The study was conducted by ExxonMobil Biomedical Sciences, Inc. (EMBSI)
Laboratory Operations, Mammalian Toxicology Laboratory, 1545 Route 22
East, P.O. Box 971, Annandale, New Jersey 08801-0971.  The EMBSI

Justification for Selection of Test System

The rat is one of the species required by the EPA for the developmental
toxicity testing requirement of Section 211b of the Clean Air Act (EPA,
1994).

Justification of Dosing Route

Exposure by inhalation is a likely route of human exposure.

2-1

Justification of Dose Selection

The high dose of 20,000 mg/m3 was selected based on safety concerns as
one-half of the Lower Explosive Limit.  The low dose (2000 mg/m3) was
expected to produce a No Adverse Effect Level based on the results of
previous subchronic and developmental studies conducted on this
material, related materials, or some combination thereof.  The mid dose
(10,000 mg/m3) was selected as the approximate mid point between the low
and high doses to produce a dose response relationship, if one existed
in this treatment range.

Characterization of the Test Substance

The stability, identity, strength, purity, and composition or other
characteristics that appropriately identified the test substance was
performed by the testing laboratory (EMBSI).  Documentation is
maintained at ExxonMobil Biomedical Sciences, Inc., Annandale, New
Jersey.  Characterization will be reported as part of EMBSI Study
167490.  Additionally, Appendix J shows the stability of the test
substance over the course of the exposure interval.

The documentation of methods of synthesis, fabrication, and/or
derivation of the test fuel were the responsibility of the Sponsor. 
This was not completed when the study initiated, but is currently
maintained by the Sponsor.

TEST SUBSTANCE   (CONT'D)

Analysis of Mixtures

Nominal Concentration.  A nominal exposure concentration was calculated
on a daily basis.  The net weight of test substance used was determined
and was divided by the total volume of air passing through the chamber
to give the nominal concentration.

Analytical Concentration.  The concentration of the test atmosphere in
each chamber and the chamber room was determined approximately hourly
during each exposure by on-line gas chromatography.  The chamber
concentrations were measured in the breathing zone of the rats.  A
backup analytical device (calibrated infrared vapor monitor) was also
available.  The hourly chromatographic analyses showed five major
components of the test atmosphere and was used to assess the stability
of the test substance over the duration of the study.

Additionally, a sorbent tube sample of the test atmosphere was collected
by drawing a known volume of the test atmosphere from each chamber 
through a calibrated critical orifice once during each week of the
study.  These samples were stored in a freezer and analyzed by the
detailed capillary/GC method used for the initial characterization
analysis of the liquid test substance.This analysis was done to
determine component proportions of the test material atmosphere compared
to the liquid test material. 

		

Chamber Homogeneity.  Distribution samples were drawn from twelve
different points within the chamber at each exposure level during the
validation of the exposure system for this study.

Particle Size Analysis.  A particle size determination of the aerosol
portion of the test atmosphere was conducted at least once during the
chamber trials for Study 171334 from the 0 mg/m3 and 20,000 mg/m3
concentrations.  The particle size determination was repeated for the
20,000 mg/m3 concentration due to a problem with the original
determination.  The samples were taken using a multistage cascade
impactor.  Preweighed glass fiber filters were used to collect aerosol
on each stage, which were associated with specific cutoff diameters for
aerodynamic particle size in microns.  Since minimal aerosol was
present, no further calculations were performed.

Sample Retention 

No retention samples were taken due to the practical and safety
considerations of storing a mixed gas/liquid phase substance under
pressure.

EXPERIMENTAL DESIGN

Mating

On the initial scheduled mating day, females were placed in males' cages
in a 1:1 (male:female) ratio.  Males and females were paired based on
sequential Physical Identification Numbers.  A sufficient number of
animals were co-housed in an attempt to produce an acceptable number of
mated animals to accommodate lab scheduling.  Mating was confirmed on
the following morning by observation of a copulatory plug (vaginal). 
The day on which mating was confirmed was considered Day 0 of gestation
(GD 0).  After confirmation of mating, each mated female was returned to
its own cage.  New females then were placed in the males' cages until
the required number of mated females was obtained by continuous
cohabitation in consideration of lab scheduling.  Mated females
subsequently were assigned to dose groups by a computer generated body
weight sorting program (WEIGHT) using the GD 0 body weights to ensure
mean body weight was similar between all groups on GD 0.

Administration of Test Substance and Exposure Schedule

The experimental and control animals were placed (whole body) into 1.0
M3inhalation chambers that were operated under dynamic conditions. The
exposure period was at least 6 hours per day. The test substance
atmosphere generation system was started after the last animal was
placed in the exposure chambers and the generation system was stopped
six hours later.  The animals remained in the chambers for at least an
additional 23 minutes (theoretical cequilibration time) while the test
atmosphere cleared.  The animals were exposed from GD 5 through GD 20.

The Chamber

The chambers used for exposure are stainless steel and glass and have a
total volume of approximately 1.0 M3.  They operated at a flow rate
(approximately 12-15 air changes/hour) sufficient to ensure timely
equilibration.  The flow of air through each chamber was monitored
continuously using a calibrated flow measuring device and recorded
approximately every 30 minutes.  All chambers were maintained at a
slight negative pressure.  The pressure was monitored continuously and
recorded approximately every 30 minutes.

3-7

EXPERIMENTAL DESIGN   (CONT'D)

The Test Atmosphere

The control group was exposed to clean filtered air under conditions
identical to those used for groups exposed to the test substance.  The
test substance was administered fully vaporized in the breathing air of
the animals.  The test atmosphere composition and concentration remained
constant at each exposure level over the daily six-hour period. The
daily mean exposure concentrations were within ± 10% of the target
exposure levels with the exceptions listed in the Protocol Exceptions
section. 

Experimental Evaluation

Animals were examined for viability at least twice daily during the
study.  Body weights were taken prior to selection, and on GD 0, 5, 8,
11, 14, 17, 20, and 21.  Food consumption was measured for mated females
on GD 5, 8, 11, 14, 17, 20, and 21.  A clinical examination was given to
each female prior to selection, and daily during gestation. 
Additionally, group observations of the animals for mortality and
obvious toxic signs while in the chambers were recorded at 15, 30, 45,
and 60 minutes after initiation of the exposure and then hourly during
each exposure.

Euthanasia and Cesarean Section

Euthanasia of the dams was by CO2 asphyxiation followed by
exsanguination.  A gross necropsy was performed on all confirmed-mated
females.

The fetuses were placed in a refrigerator to slow down and eventually
terminate vital signs after the external examination and weighing.  

Mated females were euthanized on GD 21.  Body weights were recorded on
the day of necropsy. Uterine weights with ovaries attached were recorded
at the time of necropsy.  Uterine contents were examined and the numbers
and locations of implantation sites, early and late resorptions, live
and dead (alive or dead in utero) fetuses were counted.  Corpora lutea
also were counted.  The uteri of all apparently non-pregnant females
were stained with 10% ammonium sulfide to confirm pregnancy status.

Evaluations of dams during cesarean section and subsequent fetal
evaluations were conducted without knowledge of treatment group in order
to minimize bias.

3-8

EXPERIMENTAL DESIGN   (CONT'D)

Examination of Fetuses

Each fetus was weighed and examined externally for gross malformations. 
Fetal sex was determined by external examination and confirmed
internally only on those fetuses receiving visceral examinations.

The viscera of approximately one-half of the fetuses of each litter were
examined by fresh dissection (Staples, 1974; Stuckhardt and Poppe,
1984).  After these fetuses were examined, they were decapitated.  The
heads were preserved in Bouin's solution for at least two weeks, then
rinsed and subsequently stored in 70% ethanol.  Free-hand razor blade
sections of the Bouin's-fixed fetal heads were examined for the presence
of abnormalities.  The remaining live fetuses (alive in utero) were
eviscerated, processed by double staining with Alizarin red and Alcian
blue, and examined for the presence of bone and cartilage malformations
and ossification variations. 

Fetal evaluations were conducted without knowledge of treatment group in
order to minimize bias.

Tissue Preservation

Fetal heads were fixed in Bouin's solution and then preserved in 70%
ethanol.  The fetal skeletons were preserved in glycerine with thymol
after they were processed and stained.

Records

A copy of the protocol, final report, raw data, computer generated
listings of raw data, supporting documentation, and tissue specimens are
maintained in the EMBSI Toxicology Laboratory Archives.

Statistical Analysis 

Statistical evaluation of equality of means was done by an appropriate
one way analysis of variance and a test for ordered response in the dose
groups.  First, Bartlett's Test was performed to determine if the dose
groups had equal variance (Snedecor and Cochran, 1989).  If the
variances were equivalent, the hypothesis that there was no difference
in response between the groups was tested using a standard one-way
analysis of variance (Snedecor and Cochran, 1989).  If the variances
were equal, the testing was done using parametric methods, otherwise
nonparametric techniques were used.  

Continuous data were tested for statistical significance as follows: 
Where applicable, percentages were calculated and transformed by
Cochran's transformation, followed by the arc sine transformation
(Snedecor and Cochran, 1989).  The raw percentages and the transformed
percentages both were tested for statistical significance.  

3-9

EXPERIMENTAL DESIGN (CONT'D)

Statistical Analysis (Cont'd)

For the parametric procedures, a standard one way ANOVA using the F
distribution to assess significance was used (Snedecor and Cochran,
1989).  If significant differences among the means were indicated,
Dunnett's Test was used to determine which treatment groups differed
significantly from control (Dunnett, 1964).  In addition to the ANOVA, a
standard regression analysis for linear response in the dose groups was
performed.  The regression also tested for linear lack of fit in the
model.

For the nonparametric procedures, the test of equality of means was
performed using the Kruskal-Wallis Test (Hollander and Wolfe, 1973).  If
significant differences among the means were indicated, Dunn's Summed
Rank Test was used to determine which treatment groups differed
significantly from the control (Hollander and Wolfe, 1973).  In addition
to the Kruskal-Wallis Test, Jonckheere's Test for monotonic trend in the
dose response was performed.  

Bartlett's Test for equal variance was conducted at the 1% level of
significance.  All other tests were conducted at the 5% and 1% level of
significance.  However, the 5% level of significance was considered
statistically significant for these analyses.  The 1% level of
significance was reported as additional information.

The following data were not included in the statistical analyses:

Gestation body weight and body weight change data for females that were
not pregnant

Gestation food consumption for females that were not pregnant

Means and standard deviations were calculated for animal, exposure and
chamber environmental data.  The coefficient of variation also was
calculated when considered relevant for the exposure  data.

3-10

EXPERIMENTAL DESIGN (CONT'D)

Statistical Analysis (Cont'd)

Fetal body weight was analyzed by a mixed model analysis of variance
that provided an accurate statistical model of the biology.  The
analysis used the litter as the basis for analysis and effectively used
the litter size as a covariate.  The model considered dose group, litter
size, and fetal sex as explanatory variables.  If the overall effect of
dose, or the dose by sex effect, was statistically significant the dose
groups means were tested pairwise vs. the control group using least
squares means.  The least squares means allowed comparisons that
accounted for differences in litter size and sex.  The mathematical
model was based on a paper by Chen, et al (1996).  The analysis was run
using SAS with code suggested in Little, et al (1997).  

The analysis of anomalies (malformations or variations) was based on a
Generalized Estimating Equation (GEE) application of the linearized
model, Ryan (1992).  The model used the litter as the basis for analysis
and considered correlation among littermates by incorporating an
estimated constant correlation and the litter size as a covariate.  If
the overall effect of dose, or the dose by sex effect, was statistically
significant the dose groups were tested pairwise vs. the control group
using least squares means.  The least squares means allowed comparisons
that accounted for differences in litter size.  Three categories of
anomalies were tested, and within each category specific anomalies also
were tested.  In addition to the category specific anomalies a series of
combined analyses were performed within each category as applicable: 

Combined Malformations and Variations for All Fetuses

Combined Malformations and Variations for Alive Fetuses

Survival Bar Graph:  Appendix A

Incidence of Gestation Observations:  Appendix B

Individual Gestation Observations:  Appendix B

All maternal animals survived to scheduled study termination on GD 21. 
One female in each group was not pregnant.

There were no clinical signs indicative of maternal toxicity.  The
majority of dams in all dose groups were free of observable
abnormalities during the entire gestation period.  Clinical signs were
limited to alopecia of the trunk for one control and one 2000 mg/m3
target female and dried ocular discharge for one 20,000 mg/m3 target
female.  Clinical signs were not evident in the 10,000 mg/m3 target
dams.

GESTATION BODY WEIGHT

Mean Gestation Body Weight and Body Weight Change:  Appendix C

Individual Gestation Body Weight and Body Weight Change:  Appendix C

There were no statistically significant differences in the mean
gestation body weight between treated and control dams at any interval
during the gestation period.  There also were no statistically
significant differences in mean uterine weight between treated and
control dams.  There was a statistically significant decrease in mean
body weight change in the dams of the 20,000 mg/m3 target concentration
at the GD 8-11 interval versus control.  Additionally, there was a
statistically significant linear decrease in body weight change in the
treated groups for this interval and for GD 0-21 corrected for uterine
weight.

GESTATION FOOD CONSUMPTION

Mean Gestation Food Consumption:  Appendix D

Individual Gestation Food Consumption:  Appendix D

There was a statistically significant decrease in mean food consumption
in the 20,000 mg/m3 target dams at the GD 8-11 interval versus control. 
There also was a statistically significant linear decrease in food
consumption in the treated groups for this interval and the GD 5-8
interval.  However, the food consumption in the treated groups was not
statistically significantly different from the control at the GD 5-8
interval, but there was a statistically significant difference between
the treated groups.  There were no other statistically significant
differences in mean gestation food consumption between treated and
control dams during the remainder of the gestation period.

GROSS POSTMORTEM OBSERVATIONS

Incidence of Gross Postmortem Observations:  Appendix E

Individual Gross Postmortem Observations:  Appendix E

The gross postmortem examination of the dams revealed alopecia for one
2000 mg/m3 target dam.  All other dams were free of grossly observable
abnormalities.

UTERINE IMPLANTATION DATA

Mean Uterine Implantation Data:  Appendix F

Individual Uterine Implantation Data:  Appendix F

There were no statistically significant differences in the uterine
implantation parameters between the control and the treated groups. 
However, there were statistically significant linear decreases in the
number of resorptions, resorptions/implantation, transformed
resorptions/implantation % postimplantation loss, and the total number
of affected fetuses in the treated groups.  Inversely, there were
statistically significant linear increases in the fetuses/implantation
and the transformed fetus/implantation.  These trends were not
indicative of toxicity.  Additionally, there were no dead fetuses in any
group.

RESULTS AND CONCLUSIONS/DISCUSSION (CONT’D)

FETAL OBSERVATIONS (CONT’D)

External Observations

There were no statistically significant differences from the control
group in the treated groups for the incidence of fetal external
observations.  External observations were limited to stunted, fetus
discolored red, malrotated hindpaw, filamentous tail, microstomia, and
cleft palate.

Visceral Observations

There were no statistically significant differences from the control
group in the treated groups for the incidence of fetal visceral
observations.  Visceral observations were minimal and were limited to
low incidences of anophthalmia, hydroureter, hydronephrosis, dilated
cerebral ventricle, malpositioned nasal septum, retinal fold, and
hydrocephaly.

Skeletal Observations

Skeletal observations are listed in Appendix H.  The most frequently
noted observations during fetal examinations were bifid centra of the
thoracic vertebrae, rudimentary lumbar ribs, and hypoplastic anlage of
the thoracic vertebral centra.  The incidence of dumbbell-shaped
vertebral centra was statistically significantly increased in the 10,000
mg/m3 target group and the incidence was slightly greater than observed
in the historical control data.  There was also an increased incidence
of dumbbell-shaped vertebral centra anlage at 2,000 mg/m3. These
increases were not considered biologically significant or treatment
related due to the lack of a dose response.

Several related skeletal observations, such as unossified and
hypoplastic vertebral centra, were combined for statistical analysis
(Appendix K).  There were no statistically significant differences from
the control group in the treated groups for combined related skeletal
observations.

CV - Coefficient of variation

The particle size determination was performed once for the control
chamber and twice for the 20,000 mg/m3 target chambers.  The initial
particle size determination for the 20,000 mg/m3 target chamber
collected 7200 ug of particles while the control chamber had no
particles.  The particles collected from the 20,000 mg/m3 target chamber
were considered to be due to dander and fur in the make-up air and no
particles were detected in the 20,000 mg/m3 target chamber during the
repeat of the particle size determination.  Therefore, there was no
aerosol component to the chamber concentrations.

The oxygen levels in the chambers ranged from 20.7 to 20.9% at the
intervals when they were monitored.  The noise level in the chambers
ranged from 72.8 to 81.2 db.  The light intensity in the chamber rooms
ranged from 38.0 foot-candles to 44.3 foot candles.

DISCUSSION

There was evidence of maternal toxicity in this study at the 20,000
mg/m3 target exposure group as indicated by  statistically significant
decreases in mean body weight change and mean food consumption at the GD
8-11 interval.  However, the decrease in these parameters did not result
in a statistically significant decrease in body weight at GD 11 or
statistically significant differences in the GD 5-21 or GD 0-21 body
weight change intervals..  

There were no treatment-related statistically significant differences
between the control and the GMVC treated groups for uterine implantation
data, fetal body weights, and external, visceral, and skeletal
observations.  The incidence of dumbbell-shaped vertebral centra was
statistically significantly increased in the 10,000 mg/m3 target group
and the incidence was slightly greater than observed in the historical
control data. The incidence of dumbbell-shaped vertebral centra anlage
(cartilaginous structure) was also statistically increased in the 2,000
mg/m3 target goup compared to the control group.  However, these
observations were not considered related to treatment due to the lack of
a dose response.

In conclusion, administration of the test substance to rats by
whole-body inhalation exposure during the period of organogenesis and
fetal growth resulted in signs of slight maternal toxicity and no
developmental toxicity. 

Therefore, the No Observable Adverse Effect Level for maternal toxicity
was established at the 10,000 mg/m3 target exposure level and the No
Observable Adverse Effect Level for developmental toxicity was
established at 20,000 mg/m3 target exposure level for this study.

PROTOCOL EXCEPTIONS

ANIMALS OUT OF WEIGHT RANGE:  Three animals were over the
protocol-specified 200-300 gram body weight range at Gestation Day 0. 
These animals were in the 2,000 mg/m3 target group (#ICK386F, 305 g; and
#IGK452F, 301 g) and the 20,000 mg/m3 target group (#IGK429F, 303 g).

This deviation had no adverse effect on the study results or integrity.

MEAN CHAMBER CONCENTRATION:  The mean chamber concentrations for
treatment group chambers were outside the acceptable range (( 10%) in
seven instances.  The following is a list of the dates and the extent of
the deviation:

Date			Required Concentration (mg/m3)	Mean Concentration (mg/m3)

August 27, 2001			10,000				11180

September 3, 2001			10,000				11161

September 4, 2001			2000				2236

September 4, 2001			10,000				11075

September 5, 2001			2000				2455a

September 7, 2001			10,000				12790

September 7, 2001			20,000				16100

a – This deviation was caused by a very high value (3897 mg/m3) at the
fifth hour of the exposure.  The cause of this high value was unknown.

These deviations had no adverse effect on the study results or
integrity.

CHAMBER TEMPERATURE AND HUMIDITY:  Due to the method used to generate
the test substance atmospheres, the chamber-room air was kept as cool as
possible to keep the temperature in the 10,000 mg/m3 and the 20,000
mg/m3 target concentration chambers from exceeding the protocol-defined
range. The cooler room air resulted in numerous instances of the mean
temperature and humidity in the control chamber being below the protocol
defined range.  The decreased temperature also caused the humidity in
the chambers to be above the protocol-defined range on numerous
occasions.  Additionally, the mean temperatures were above the protocol
required range on several occasions.  The individual temperature and
humidity deviations are noted in Appendix I as bold italicized values.

These deviations had no adverse effect on the study results or
integrity.

CHAMBER CONCENTRATION OF SEPTEMBER 15, 2001:  At the 1-hour sampling for
the chamber concentration on September 15, 2001 the gas chromatography
system did not initiate.  The system was restarted and it worked
normally for the rest of the sampling intervals on September 15, 2001.

These deviations had no adverse effect on the study results or
integrity.

4-6

PROTOCOL EXCEPTIONS (CONT'D)

ANIMAL ROOM TEMPERATURE AND HUMIDITY:  The temperature and humidity were
out of range in the animal room on the following days:

Date				Deviation

August 25, 2001		Humidity of 73.3% RH

August 26, 2001		Humidity of 78.9% RH

August 26, 2001		Temperature of 67.8(F

These deviations had no adverse effect on the study results or
integrity.

LIGHT INTENSITY, NOISE LEVEL AND OXYGEN LEVEL:  The protocol specified
that the light intensity, noise level and oxygen level be measured three
times during the study (the first day of exposures, during the second
week of exposures and the last day of exposures).  These parameters were
measured four times during the study, the extra measurements were taken
during week three of exposures.

These deviations had no adverse effect on the study results or integrity

No other circumstances occurred that would have affected the quality or
integrity of the data.

Exposure Chambers

   

	The chambers used in this study were constructed of stainless steel and
glass and had a total volume of approximately 1.0 m3.  They were
operated at an airflow rate of 200 liters per minute ensuring 12 air
changes per hour and a theoretical equilibration time (T99) of 23
minutes.  The chamber volume and airflow were considered adequate to
ensure an oxygen level greater than 19% and an animal loading below 5%. 
The chamber airflow rate was monitored continuously with a calibrated
flow-limiting orifice and differential pressure gauge and recorded
approximately every 30 minutes.  All of the chambers were maintained at
a slight negative pressure to the room.

Test Atmosphere Generation

      

	Figure I-1 presents a schematic of the test atmosphere generation and
exposure system.

Aliquots of the test substance for use in the daily conduct of the study
were received in gas cylinders (~20 L nominal volume) via a specially
constructed distribution manifold.  A manifold system maintained the
test substance under nitrogen pressure,  ensuring that the transferred
substance remained in liquid phase and retained the same composition as
the original container.  

The test substance was delivered via a diptube from the outlet valve of
the cylinder to a variable area rotameter which regulated the rate of
liquid flow into a heated glass round-bottom flask.  The test substance
volatilized within the flask and the resulting vapors mixed with the
supply air as they were drawn into the exposure chamber.  

Chamber Environmental Conditions

Chamber temperature and humidity were monitored by wet/dry bulb
hygrometers and recorded at approximately thirty minute intervals
throughout each exposure.

Analytical Procedures

Gas chromatograph operating conditions: Table I-2

Mean exposure data: Table I-2

Summary of exposure data: Table I-3

	Exposure concentrations were determined on both a nominal and
analytical basis.  Nominal concentrations for each exposure level were
calculated by weighing the tank containing the test substance before and
after exposure and dividing the net loss in weight by the total volume
of air passing through the chamber during the exposure.

	Analytical exposure concentrations were determined hourly during each
exposure by on-line gas chromatography (Hewlett Packard 6890).  Samples
of the chamber atmosphere were continuously delivered to the GC via
1/8” teflon tubing connected to an automated 12-port multiposition gas
sampling valve.  The multiposition valve was programmed to sequentially
direct each stream to a sample loop which injected a fixed sample volume
(2 cc) directly onto the column for analysis.  A complete sampling cycle
was performed during each hour of exposure. 

	The analytical system was calibrated against a series of known
concentrations of the test substance in air.  The air concentrations
were determined by injecting a weighed amount the test substance from a
gas-tight syringe into a closed loop system of a known air volume (see
schematical drawing).  The closed loop system consisted of an infrared
vapor analyzer (MIRAN 1A-CVF, Foxboro Analytical)  connected to the gas
sampling valve of the GC.  A metal bellows pump was used to circulate
the injected test substance vapors through the sample cell of the
infrared monitor and the gas sampling valve of the GC.  The response of
the infrared analyzer was monitored until the air concentration appeared
equilibrated and stable,  then three replicate samples were taken using
the gas sample loop of the GC.  The entire closed loop system was
cleared with clean air between each calibration injection.  The average
response of the GC (total peak area) for the five main constituents of
the atmosphere, at each air concentration was used to construct a linear
calibration for the test substance.

	This method permitted the GC and the infrared analyzer (a backup
analytical method) to be calibrated simultaneously and  under conditions
similar to actual chamber sampling.  Once established, the calibration
was checked daily during the study by sampling a certified standard of
n-butane, the major component of the test substance mixture.

Chamber Homogeneity

	Table I-4 presents a summary of the chamber distribution data.

	During the method development trials for this study, samples were drawn
from twelve different points within the chamber at each target
concentration to demonstrate the homogeneity of test atmosphere
distribution.

SUMMARY

Charcoal tube sorbent tube samples were received by the Analytical
Chemistry Laboratory from  inhalation chamber exposures and were
characterized for hydrocarbon distribution using capillary gas
chromatography with flame ionization detection (GC/FID).  Sorbent tube
samples were stored in a freezer pending analysis.

SAMPLE PREPARATION

The front and back sections of each charcoal sample tube were desorbed
and analyzed separately to 

assess potential sampling breakthrough.  The charcoal tube sections were
desorbed with 3.0 mL carbon disulfide (CS2) for at least 30 minutes. 
Aliquots were analyzed by GC-FID.

STANDARDIZATION

A standard mixture was prepared in (CS2) containing each of the 18
target hydrocarbons plus MTBE oxygenate.  Analysis of the standard
mixture was used to confirm the relative retention times of each target
hydrocarbon and was not used for quantitative purposes.  Since MTBE
coelutes with the hydrocarbon 2,3 dimethylbutane, a distribution factor
was applied to the coeluting pair to calculate the final hydrocarbon -
oxygenate distribution.  This distribution factor (96% MTBE: 4% 2,3
dimethylbutane) was determined as part of the EMBSI neat test substance
characterization study 167490.

CHARACTERIZATION

Characterization of the neat MRD-00-713 (gasoline vapor condensate with
MTBE) was performed separately and will be reported as part of EMBSI
Study 167490. Neat test substance characterization included a similar
analysis of the relative distribution of target hydrocarbons and
oxygenate as was performed  for the chamber sorbent tube samples.

INSTRUMENT CONDITIONS FOR MRD-00-713 

ON CHARCOAL SORBENT TUBE 

The following GC conditions and equipment were used to determine the
hydrocarbon distribution of test substance on chamber characterization
sorbent tubes:

GC	Perkin Elmer XL Autosystem

Detector Type (range)	FID (2^4)

Detector Temperature; (gas flows)	225°C (H2 45 mL/min; Air  450 mL/min)

Injector Temperature (Split ratio)	200°C (split injection ~5:1)

Injection Volume	1.0 µL 

Analytical Column	Supleco Petrocol DH 150 fused silica capillary column
(150m x 0.25µm; 1.0µm film thickness)

Oven Temperature Program	35(C (hold 130 minutes); ramp @ 2(C/minute to
200(C  

Data Collection	Perkin Elmer Nelson Turbochrom (TC4) version 4.1 

Carrier Gas Program	65 psi (He)

RESULTS

Hydrocarbon characterization was performed on an area percent basis for
each of the 18 target hydrocarbons and MTBE oxygenate. Results are
listed in Table J-1. 

Analysis of the 20,000 mg/m3 (high) exposure level sample taken during
study Week 2 (4 September 01) detected none of the target hydrocarbons
and was likely due to a sampling problem.  For the remainder of the
samples, the hydrocarbon and MTBE distribution measured from the chamber
characterization samples was in good agreement with the distribution
measured from characterization of neat MRD-00-713 performed as part of
EMBSI study 167490.

Analysis Of Fetal Data From A Whole-Body Inhalation Developmental
Toxicity 

Study In Rats With Baseline Gasoline with MTBE Vapor Condensate
(MRD-00-713)

This report details the statistical analysis of fetal body weight and
anomaly data from ExxonMobil Study 171334.  The study was conducted to
evaluate the potential developmental toxicity of Baseline Gasoline with
MTBE Vapor Condensate (GMVC).  GMVC was administered via whole-body
inhalation exposure to pregnant rats during the period of major
organogenesis and fetal growth.  GMVC was administered by whole-body
inhalation exposure to 24 confirmed-mated Crl: CD(SD)IGS BR female rats
at target doses of 0 (air control) 2000, 10,000, and 20,000 mg/m3 for
six hours (plus the theoretical equilibration time) daily from Gestation
Day (GD) 5 through GD 20. 

The fetal body weight was analyzed by a mixed model analysis of variance
that provides an accurate statistical model of the biology.  The
analysis used the litter as the basis for analysis and effectively used
the litter size as a covariate.  The model considered dose group, litter
size, and fetal sex as explanatory variables.  When the overall effect
of dose, or the dose by sex effect, was statistically significant the
dose groups means were tested pairwise vs. the control group using least
squares means.  The least squares means allows comparisons that account
for differences in litter size and sex.  The mathematical model is based
on a paper by Chen, et al (1996).  The analysis was run using SAS with
code suggested in Little, et al (1997).  

The analysis of anomalies (malformations or variations) was based on a
Generalized Estimating Equation (GEE) application of the linearized
model, Ryan (1992).  The model used the litter as the basis for analysis
and considered correlation among littermates by incorporating an
estimated constant correlation and the litter size as a covariate.  When
the overall effect of dose, or the dose by sex effect, was statistically
significant the dose groups were tested pairwise vs. the control group
using least squares means.  The least squares means allowed comparisons
that accounted for differences in litter size.  There were four
categories of anomalies tested, and within each category specific
anomalies were also tested.  In addition to the category specific
anomalies a series of combined analyses were performed within each
category: 

Combined Malformations and Variations for All Fetuses

Combined Malformations and Variations for Alive Fetuses

Malformations for All Fetuses

Malformations for Alive Fetuses

Variations for All Fetuses

Table I lists the four categories and corresponding sub-categories. 
Within the skeletal category several subcategories were combined into a
group of similar anomalies.  For example in the Category Skeletal the
separate sub-categories of “SKELETAL/VERTEBRAE (CE): Presacral” and
“SKELETAL/VERTEBRAE (L):  Presacral” were combined into a
sub-category “SKELETAL/VERTEBRAE:  Extra presacral
vertebrae(combined)”.  In this combined category an animal is counted
once when he, or she, exhibits more than one characteristic.  The
sub-categories that were combined are listed in the Sub-categories
Combined column of Table 1 by the sub-category number.  The analyses
were run using SAS.

RESULTS:

BODY WEIGHT ANALYSIS

There was no statistically significant difference in the mean fetal
litter weights among the dose groups.  Table II shows the mean fetal
weight and the least squares mean fetal weight.  The dose and dose by
sex interaction were not statistically significant indicating there was
not a dose related effect.

Dose Group

(mg/m3)	n litters	n fetuses	observed fetus mean (gm)	Least squares fetus
mean (gm)*

0	24	358	5.38	5.38

2,000	24	362	5.46	5.45

10,000	24	369	5.29	5.30

20,000	24	366	5.40	5.42

                  *The least squares mean accounts for litter size.

ANOMALY ANALYSES

Of the 27 individual anomaly analyses the count of skeletal dumbbell
vertebral centra indicated a statistically significant difference
between the dose group (10,000 mg/m3) and the control group, and the
count of dumbbell-shaped vertebral centra anlage for females indicated a
statistically significant difference between the dose group (2,000
mg/m3) and the control group .  None of the other measures indicated
statistically significant differences among the dose groups.  Incidence
tables are provided in the appendix.

CONCLUSION:

Based on these findings, administration of the test substance at the
exposures tested is associated with a increased incidence of skeletal
dumbbell vertebral centra in the 10,000 mg/m3 dose group relative to the
control group and with an increased incidence for females of skeletal
dumbbell-shaped vertebral centra anlage in the 2,000 mg/m3 dose group
relative to the control group.
