鼠伤寒沙门氏菌/肝微粒体酶试验(Ames 试验)经世界各国十余年的运用和验证,已被推为迄今筛选化学诱变剂的首选试验。我们运用该试验方法对国产农药喹恶硫磷、植物生长调节剂 P-51和氯化亚锡进行了检测,旨在探索其诱变性。材料和方法一、检品:喹恶硫磷为四川省化工研究所农药室合或之纯品(99%);P-51由四川省永川天然气化工研究所提供,纯度95%; Salmonella typhimurium / liver microsomal enzyme test (Ames test) by more than 10 years of use and verification of the countries in the world, has been pushed so far for the screening of chemical mutagens preferred test. We used this test method to test the domestic pesticide quinalphos, plant growth regulator P-51 and stannous chloride to explore its mutagenicity. Materials and methods First, the seizure of goods: Quinapta as pesticide laboratories in Sichuan Institute of Chemical Industry combined or pure (99%); P-51 by the Sichuan Yongchuan Natural Gas Chemical Institute, a purity of 95%;
