ABSTRACT

The developmental toxicity of gasoline with ETBE (ethyl tert butyl
ether) 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 were signs
of slight maternal toxicity early in the exposure period as indicated by
statistically significant decreases in body weight change in the 20,000
mg/m3 group for the GD 8–11 interval.  Statistically significant
decreases in food consumption also were evident at the GD 8-11 interval
for the 10,000 and 20,000 mg/m3 target concentration groups and at the
GD 11-14, and GD 5-20 intervals for the 20,000 mg/m3 target
concentration group.  However, no statistically significant decreases in
body weights were noted at any interval in any treatment group.  There
were no statistically significant differences for uterine implantation
data, external, visceral, and skeletal observations.  Thus, exposure to
gasoline with ETBE vapor condensate at a target concentration of 20,000
mg/m3 caused slight maternal toxicity but not developmental toxicity. 
Therefore the No Observable Adverse Effect Level for this study was
10,000 mg/m3 for maternal toxicity and 20,000 mg/m3 for developmental
toxicity.

SUMMARY

This study was conducted to evaluate the potential developmental
toxicity of the test substance, Gasoline with ETBE Vapor Condensate
(GEVC).  GEVC was administered via whole-body inhalation exposure to
pregnant rats during the period of major organogenesis and fetal growth.
 GEVC was administered by whole-body inhalation exposure to 25
confirmed-mated Crl:CD®(SD)IGSBR female rats at target concentrations
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 slight maternal toxicity in this study at the
target concentration of 20,000 mg/m3.  A statistically significant
decrease in body weight change was evident in the 20,000 mg/m3 target
concentration group for the GD 8–11 interval.  Statistically
significant decreases in food consumption also were evident at the GD
8-11, GD 11-14, and GD 5-20 intervals for the 20,000 mg/m3 target
concentration group.  No statistically significant decreases in body
weights were noted at any interval in any treatment group.  The only
evidence of maternal toxicity at the 10,000 mg/m3 target concentration
was a statistically significant decrease in food consumption on GD 8-11;
this was not considered clear evidence of maternal toxicity, since no
other time intervals were significantly affected and since there was no
significant effect on maternal body weight or body weight gain at any
time interval. All dams survived to scheduled terminal sacrifice on GD
21.  At the GD 21 cesarean section, two 2000 mg/m3 target concentration
animals, one animal in the 10,000 mg/m3 target concentration group, and
one animal in the 20,000 mg/m3 target concentration group were found to
be not pregnant (i.e. no evidence of implantation sites).  

All animals were free of clinical or postmortem observations
attributable to treatment with GEVC. 

1-1

SUMMARY   (CONT'D)

There were no treatment-related statistically significant differences
between the control and the GEVC treated groups for uterine implantation
data, external observations, visceral and skeletal observations.  

In conclusion, administration of GEVC to rats by whole-body inhalation
exposure during the period of organogenesis and fetal growth produced
signs of slight maternal toxicity during the early period of dosing at
the target concentration of 20,000 mg/m3 as indicated by decreased body
weight change and decreased food consumption.  There were no treatment
related signs of toxicity in the fetuses.

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

INTRODUCTION (CONT'D)

Justification of Dosing Route

Exposure by inhalation is a likely route of human exposure.

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.

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 were 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 until after the end of
the exposure phase of the study and then transferred to the analytical
chemistry laboratory.  The samples were desorbed 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 from the control and 20,000
mg/m3 target concentration during the chamber trials.  The sample was
taken using a multistage cascade impactor.  Preweighed glass fiber
filters were used to collect aerosol on each stage, which are associated
with specific cutoff diameters for aerodynamic particle size in microns.
 Since minimal aerosol was present, no further calculations were
performed for the aerodynamic diameter, geometric standard deviation, or
the estimated percents of the aerosol less than or equal to 1, 10, and
15 microns in size.

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.

4	. High	25	20,000

Administration of Test Substance and Exposure Schedule

The experimental and control animals were placed (whole body) into 1.0
M3-inhalation chambers that were operated under dynamic conditions. The
exposure period was six 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 equilibration 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 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 generally 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.

EXPERIMENTAL DESIGN   (CONT'D)

Examination of Fetuses

Each live fetus (alive in utero) 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.

Prior to visceral examinations any live fetuses were euthanized by a
subcutaneous injection with sodium pentobarbital.  The viscera of
approximately one-half of the live fetuses (alive in utero) 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. 

Fetus #2 of Dam IGL353 in the 2000 mg/m3 target concentration group was
a conjoined twin that was examined for both visceral and skeletal
anomalies.

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
were maintained in the EMBSI Toxicology Laboratory Archives until they
were returned to the Sponsor.

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.  

3-9

EXPERIMENTAL DESIGN (CONT'D)

Statistical Analysis (Cont'd)

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.  

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

Combined Malformations and Variations for Dead Fetuses 

Malformations for All Fetuses

Malformations for Alive Fetuses

Malformations for Dead Fetuses

Variations for All Fetuses

RESULTS AND CONCLUSIONS/DISCUSSION

CLINICAL INLIFE OBSERVATIONS AND SURVIVAL 

Survival Bar Graph:  Appendix A

Incidence of Gestation Observations:  Appendix B

Individual Gestation Observations:  Appendix B

All dams survived to scheduled terminal sacrifice on GD 21.  At the GD
21 cesarean section two 2000 mg/m3 target concentration animals, one
animal in the 10,000 mg/m3 target concentration group and one animal in
the 20,000 mg/m3 target concentration group were found to be not
pregnant (i.e. no evidence of implantation sites). 

There were no clinical signs indicative of maternal toxicity
attributable to the test material.  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 three
control dams and one dam from the 20,000 mg/m3 target concentration
group, and alopecia of the extremities was evident in one dam for the
10,000 mg/m3 target concentration group.  Clinical signs were not
evident in the 2000 mg/m3 target concentration dams.

GESTATION BODY WEIGHT

Mean Gestation Body Weight and Body Weight Change:  Appendix C

Individual Gestation Body Weight and Body Weight Change:  Appendix C

A statistically significant decrease in body weight change was evident
in the 20,000 mg/m3 target concentration group for the GD 8-11 interval.
 However, no statistically significant decreases in body weights were
noted at any interval in any treatment group compared to controls. 
Additionally, statistically significant linear trends (decreases) were
detected in body weight change for the GD 5-8, GD 8-11, GD 11-14, and GD
0-21C intervals and in the body weight for GD 14.  No other differences
in body weight change were evident.

GESTATION FOOD CONSUMPTION

Mean Gestation Food Consumption:  Appendix D

Individual Gestation Food Consumption:  Appendix D

Statistically significant decreases in food consumption were evident at
the GD 8-11 interval for the 10,000 and 20,000 mg/m3 target
concentration groups and at the GD 11-14, and GD 5-20 intervals for the
20,000 mg/m3 target concentration group.  Additionally, statistically
significant linear trends (decreases) were detected in food consumption
for the GD5-8, GD 8-11, GD 11-14, GD 17-20, GD 5-20, and GD 0-21
intervals. No other differences in food consumption were evident.

Individual Gross Postmortem Observations:  Appendix E

The gross postmortem examination of the dams revealed a diverticulum of
the right horn of the uterus that was filled with liquid for one control
dam.  Alopecia of the trunk was evident for three control dams and one
20,000 mg/m3 target concentration dam.  All other dams were free of
grossly observable abnormalities.

UTERINE IMPLANTATION DATA

Individual Fetal Body Weight:  Appendix G

Statisticians Report:  Appendix K

There were no statistically significant decreases in mean fetal body
weight between the control and the treated groups. 

FETAL OBSERVATIONS

Incidence of Fetal Observations:  Appendix H

Individual Fetal Observations:  Appendix H

Statistician’s Report: Appendix K

There were no statistically significant or treatment-related differences
between the control and the treated groups for visceral and skeletal
variations and/or malformations.  There was a statistically significant
decrease in the incidence of external variations and malformations in
the 10,000 and 20,000 mg/m3 target exposure groups.  These decreases
were not considered indicative of developmental toxicity produced by
exposure to GEVC.

4-2

FETAL OBSERVATIONS (CONT'D)

External Observations

The incidences of external observations are presented in Appendices H
and K.  No malformations or variations were observed during the external
examination in the 10,000 and 20,000 mg/m3 target exposure groups. 
There was a statistically significant decrease in the incidence of
external variations and malformations in the 10,000 and 20,000 mg/m3
target exposure groups compared to controls; these decreases were not
considered indicative of developmental toxicity produced by exposure to
GEVC.  At the 2000 mg/m3 target concentration, the only external
malformation was a conjoined twin in one litter (Dam IGL353, Fetus #2). 
 Among the controls, there were two fetuses with malrotated hindpaw, one
fetus with domed head, and one dead fetus with multiple external
malformations; four control litters were affected.

Visceral Observations

The incidences of visceral observations are presented in Appendices H
and K.  The incidences of visceral malformations and variations did not
differ significantly from the control incidences.  Fetus #2 of Dam
IGL353 in the 2000 mg/m3 target concentration group was a conjoined twin
that had shared organs, small spleen, cecum not evident, small left
ventricle, a duplicate tongue, two aortas, elongated innominate,
supernumerary lobe of the lung, malpositioned carotid artery,
malpositioned subclavian artery, and malpositioned pulmonary artery. 
Visceral observations in the other fetuses in the study were minimal and
were limited to low incidences of umbilical artery arises from left,
hydroureter, hydronephrosis, and retinal fold.  Single incidences of
misshapen spleen, large atrial chamber, absent innominate artery, open
eye, and umbilical artery aneurysm, malpositioned carotid artery, and
malpositioned subclavian artery.  

Skeletal Observations

The incidences of skeletal observations are presented in Appendices H
and K.  The incidences of skeletal malformations and variations did not
differ significantly from the control incidences.  The most frequently
noted skeletal ossification variants were rudimentary lumbar ribs, bifid
centra of the thoracic vertebrae, dumbbell-shaped thoracic centra
anlage, and advanced ossification of the sternebrae.

Satisfactory chamber uniformity was observed for the 12 points in the
chamber that were analyzed.  The range of  concentrations for each
chamber are listed in Table 4-2.

Table 4-2 - Summary of Chamber Uniformity

Target concentration	2000 mg/m3	10,000 mg/m3	20,000 mg/m3

Minimum	1886	10373	20832

Maximum	2270	10997	21550

S.D. - Standard deviation

CV - Coefficient of variation

The particle size determination for the control chamber and 20,000 mg/m3
target concentration chamber detected particles at a level of 0 and 20
mg/m3 for each chamber, respectively.  These particles were judged to be
ambient background particles (e.g. animal dander) and not from the
generation of the test substance.

The oxygen levels in the chambers ranged from 19.7 to 20.7% at the
intervals when they were monitored.  The noise level in the chambers
ranged from 72.2 to 80.2 db.  The light intensity in the chamber room
ranged from 28.9 foot-candles to 62 foot candles.

The analyses of the chamber atmospheres by the analytical chemistry
group revealed that the concentrations of the components of GEVC were
stable over the course of the study.  The components present in the
highest concentrations in GEVC were isopentane (~32%), ETBE (~17%),
n-pentane (~10%),  n-butane (~9.5%), and 2-methylpentane (~5%).  Each of
the remaining components comprised less than 5% of the mixture (See
Appendix J for the results of the analyses).

DISCUSSION

There were signs of slight maternal toxicity early in the exposure
period as indicated by a statistically significant decrease in body
weight change in the 20,000 mg/m3 target concentration group for the GD
8–11 interval.  Statistically significant decreases in food
consumption also were evident at the GD 8-11, GD 11-14, and GD 5-20
intervals for the 20,000 mg/m3 target concentration group.  However, no
statistically significant decreases in body weights were noted at any
interval in any treatment group.  The only evidence of maternal toxicity
at the 10,000 mg/m3 target concentration was a statistically significant
decrease in food consumption on GD 8-11.  Based on the lack of
statistically significant decreases in mean body weight and mean body
weight change for any interval in the 10,000 mg/m3 target concentration
group, it would appear that the decrease in food consumption during a
single interval in the 10,000 mg/m3 target concentration group was not
biologically significant.  Conversely, the statistically significant
decreased food consumption in the 20,000 mg/m3 target concentration
group was associated with a decrease in the body weight change in the GD
8-11 interval and was considered biologically significant.

There were no statistically significant differences attributable to
exposure for uterine implantation data, and external, visceral, and
skeletal observations.

In conclusion, administration of GEVC to rats by whole-body inhalation
exposure during the period of organogenesis and fetal growth at a target
concentration of 20,000 mg/m3 target concentration caused slight
maternal toxicity as indicated by decreased food consumption and
decreased body weight change.  No developmental toxicity attributable to
the test material was observed at any level of exposure to GEVC.

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

PROTOCOL EXCEPTIONS

ANIMAL ROOM HUMIDITY;  The animal room humidity was outside the
protocol-defined ranged at the following times:

Date			Humidity (%RH)	Alarm Time		Time resolved

May 7, 2002		          71.3		    16:01		 Immediately

May 13, 2002		          71.9		    15:09		    15:28

May 14, 2002		          97.6		    12:47		    13:00

The causes of the excursions on May 7 and May 13, 2002 were unknown. 
The excursion on May 14, 2002 was caused by the equilibration of a new
humidity transmitter that was placed in the system to replace the
existing transmitter.

These short excursions had no effect on the study results or integrity.

MEAN CHAMBER CONCENTRATION:  The mean chamber concentration for the 2000
mg/m3 target concentration treatment group chamber was 1733 on April 27,
2002.  This deviation was due to problems with the rotameter.

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 three instances of the
temperature in the control chamber being below the protocol-defined
range and numerous instances of the temperature in the treated group
chambers exceeding the protocol-defined ranges early in the daily
exposures.  The decreased temperature also caused the humidity in the
control chamber to be above the protocol-defined range on numerous
occasions and also caused the humidity in the treated group chambers to
be above the protocol-defined range early in the daily exposure periods
on numerous occasions.  The very high humidities noted early in the
daily exposures were due to the chambers not being completely dry from
the previous days cleaning.  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.

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

Analytical calibration response curve: Figure I-3

Mean exposure data: Table I-1

Gas chromatograph operating conditions: 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 of 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 four 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.

Lighting, Noise and Oxygen Levels

Table I-5 presents a summary of the lighting, noise, and oxygen level
data.

Light intensity was measured three times during the study (the first day
of exposures, during the second week of exposures, and the last day of
exposures) in both the animal room and the chamber room.  Light
intensity was measured in the animal room in a cage approximately three
feet above the floor level.  In the chamber room the light intensity was
measured three feet above floor level in the approximate center of each
generation room.

Additionally, the oxygen level and the noise level were measured in each
exposure chamber on the first day of exposures, during the second week
of exposures, and on the last day of exposures.

Particle Size Analysis.  

Table I-6 presents a summary of the particle size data.

A particle size determination of the aerosol portion of the test
atmosphere was conducted during the chamber trials from the control and
20,000 mg/m3 target concentration chambers.  The particle size sampling
indicated aerosol concentrations of 0 and 20 mg/m3 for the control and
20,000 mg.m3 target concentration chambers.  These small concentrations
of aerosol were likely due to animal hair or dander.

The sample was taken using a multistage cascade impactor.  Preweighed
glass fiber filters were used to collect aerosol on each stage.  Each
stage was associated with specific cutoff diameters for aerodynamic
particle size in microns.

The flow of air and the duration of the flow were recorded in the data. 
This provided the information needed to convert the amount of aerosol
captured in the cascade impactor to a chamber concentration.

	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 then analyzed by GC-FID.

	STANDARDIZATION

A standard mixture was prepared in CS2 containing each of the 18 target
hydrocarbons plus ETBE 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.  

CHARACTERIZATION

Characterization of the neat MRD-00-716 (gasoline vapor condensate with
ETBE) 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.

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

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

This report details the statistical analysis of fetal body weight and
anomaly data from ExxonMobil Study 171634.  The study was conducted to
evaluate the potential developmental toxicity of Baseline Gasoline with
ETBE Vapor Condensate (GEVC).  GEVC was administered via whole-body
inhalation exposure to pregnant rats during the period of major
organogenesis and fetal growth.  GEVC 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 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.  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 allowed comparisons that
accounted 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, variations, or observations)
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
allows comparisons that account for differences in litter size.  There
were three 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

Combined Malformations and Variations for Dead Fetuses 

Malformations for All Fetuses

Malformations for Alive Fetuses

Malformations for Dead Fetuses

Variations for All Fetuses

Variations for Alive Fetuses

Variations for Dead Fetuses

In some cases there were no dead fetuses in a category.

Table I lists the four categories and corresponding sub-categories. 
Within each category several subcategories were combined into a group of
similar anomalies.  For example in the Category Skeletal the separate
sub-categories of “SKELETAL/RIBS (C7): Cervical rib; Bilateral”,
“SKELETAL/RIBS: Rudimentary supernumerary ribs”, and
“SKELETAL/RIBS (L1):  Well-formed; Left” were combined into a
sub-category “SKELETAL/RIBS:  supernumerary Ribs(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 weight difference
between the male and female pups was not consistent across the dose
groups; therefore only the mean pup weight respective of sex is
presented.

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

0	25	353	5.32	5.33

2,000	23	329	5.31	5.34

10,000	24	325	5.30	5.29

20,000	24	342	5.27	5.25

ANOMALY ANALYSES

The analyses of the incidence of combined external variations and
malformations (all fetuses) and of combined external malformations (all
fetuses) indicated a statistically significant increased incidence in
the control group relative to the dosed groups.  This finding is
considered a statistical anomaly. 

None of the malformation or variation analyses 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 not associated with a change in mean litter fetal
body weight or any change in head, external, abdomen/thorax and skeletal
malformations/variations.
