本文对杀虫畏的远期毒性及对地面水的影响进行了研究。试验结果:杀虫畏的Ames氏试验为阴性,剂量在1,500毫克/公斤以下,没有诱发大鼠肿瘤,对大鼠无致畸胎毒性,不影响大鼠繁殖功能。结合另文报告的慢性试验结果,测得杀虫畏的无作用剂量为0.15毫克/公斤体重。椐此,计算出成人每日容许摄入量为0.9毫克,其中9％可来自饮水。以成人每 This paper investigates the long-term toxicity of chlorfenadyl and its effects on surface water. Test results: Ames test of chlorfenozide was negative, and the dose was less than 1,500 mg/kg. No rat tumor was induced. There was no teratogenic toxicity to rat and no effect on rat reproductive function. In combination with the results of a chronic test reported elsewhere, the no-acting dose of chlorfenadine was 0.15 mg/kg body weight. Hereby, the daily allowable intake of adults is calculated to be 0.9 milligrams, of which 9% can come from drinking water. Every adult
