STUDIES OF CHEMICAL DISPOSITION IN MAMMALS

该项目的目的是“化学品处置的研究， 哺乳动物”，是为了进行化学处置研究 支持毒性和致癌性研究， 国家毒理学计划（NTP）。 该计划旨在提供 关于接触下列物质可能产生的急性和慢性毒性的数据： 精选化学品 承包商应进行6-10次化学处理 和毒代动力学研究。 这些研究结果提供了 预测生物累积性和毒性的依据， 提高剂量选择的准确性以及改进设计的 动物生物测定程序。 此外，化学处理和 毒代动力学研究提供的信息将允许NTP 建立毒性和生物利用度之间的关系 化学物质和/或代谢物，并允许更好地外推 实验室数据给人类。 在本项目下获得的合同将 继续先前合同N 01 ES65137和N 01 ES65138项下的工作。

The purpose of this project, entitled "Studies of Chemical Disposition in Mammals", is to procure chemical disposition studies to be performed in support of the toxicity and carcinogenicity studies conducted by the National toxicology Program (NTP). This program is designed to provide data on acute and chronic toxicity which may result from exposure to selected chemicals. The Contractor shall conduct 6-10 chemical disposition and toxicokinetic studies per year. The results of these studies provide the basis for predictions of bioaccumulation and toxicity and thereby enhance the accuracy of dose selection as well as improve the design of the animal bioassay program. Furthermore, chemical disposition and toxicokinetic studies provide information which will allow the NTP to establish the relationships between toxicity and bioavailability of chemicals and/or metabolites and permits a better extrapolation of laboratory data to humans. The contracts obtained under this project will continue the work under predecessor contracts N01ES65137 and N01ES65138.
