人口膨胀控制年度数据(Animal Data for Human Exposure Control) 数据介绍： Tetrafluoroethylene is used in the production of polytetrafluoroethylene (Teflon) and other polymers. Tetrafluoroethylene was nominated by the National Cancer Institute for toxicity and carcinogenicity studies based on the potential for human exposure to the chemical due to the large production volume and on the lack of adequate data for tetrafluoroethylene in the literature. Male and female F344/N rats and B6C3F1 mice were exposed to tetrafluoroethylene (98% to 99% pure) by whole body inhalation exposure for 16 days, 13 weeks, or 2 years. Genetic toxicity studies were conducted in mouse peripheral blood erythrocytes. 关键词： 算法,统计,人类,爆炸,控制, algorithm,statistic,human,exposure,control, 数据格式： TEXT 数据详细介绍： Animal Data for Human Exposure Control Tetrafluoroethylene is used in the production of polytetrafluoroethylene (Teflon) and other polymers.

Genetic toxicity studies were conducted in mouse peripheral blood erythrocytes. The file parise.zip contains the data for the 2 year study in the male F344/N rats for leukemias in the control and high dose group. Following is a description of the variables. Variable names appear in the first row. cid = the animal id number, days = the time of death/sacrifice M for male F for female, ONLY males are sex = given here dose = the dose level in ppm 1 if the animal developed leukemia by the leuk
