22、ures and results obtained fiom a range-finding inhalation toxicity study of Unleaded Gasoline Vapor Condensate (MI 94-02) in rats and mice via whole body exposure are presented in this report. This study was conducted at Huntingdon Life Sciences, Mettlers Road, P.O. Box 2360, East Millstone, New Jer

23、sey 08875-2360. This inhalation study was pedormed to provide range-finding information on the maternal and developmental toxicity of Unleaded Gasoline Vapor Condensate (MI 94-02) in rats and mice. Data fiom this study will be used to identi the appropriate rodent species and exposure levels to use

24、in a definitive inhalation developmental toxicity study. Unieaded Gasoline Vapor Condensate (MI 94-02) was administered as a vapor, via inhalation (whole-body) exposure, 6 howdday to 40 mated rats (1 Ogroup) during Days 6-19 of gestation and to 40 mated mice (I Olgroup) during Days 6- 17 of gestatio

25、n. Exposure levels were 300, 1000,3000, and 9000 ppm. Ten mated rats and ten mated mice which served as controls, were chamber-housed and received filtered room air only, 6 hodday over the same treatment intervals. Procedures used during the study are presented in the Materiais and Methodfleferences

26、 section of the report. Maternal and developmental toxicity data for the rat are presented in Appendices A through J and similar data for the mouse are presented in Appendices K through T. Data regarding the inhalation exposures are presented in Appendix U. Results, as well as methods used, for the

27、chamber analyses performed by the Testing Facilitys Metabolism and Analytical Department are presented in Appendix V. Historical control data for both rats and mice are presented in Appendix W. A copy of the study protocol and protocol amendments are presented in Appendix X. 2- 1 - STD=API/PETRO TR

Stabil (Meal) (PMI Feeds, Inc., St Louis, MO) was available without restriction. Each animals cage was fitted to retai

40、n a glass feeder jar with a stainless steel lid. During the acclimation period, fresh feed was provided weekly to the rats while the mice received fresh feed every three to four days. During gestation, fresh food was presented to the rats on Days O, 6 and 12. The mice were provided with fresh food o

41、n Days O, 3,6,10 and 14 of gestation. (Note: For the mice, one animai each from the control, 300,1000 and 3000 ppm groups and two animals fiom the 9000 ppm groups were not provided with fresh feeders on Day 3 of gestation due to an oversight. This oversight was not considered to have compromised the validity or integrity of the study as the feeders contained suffkient feed for the animals to Day 6.) 3-8
