用Ames试验测定了丁草胺的致变性。以鼠伤寒沙门氏菌株 TA97TA98TA100作为试测菌株,α—氨基芴为阳性诱变剂。结果不同浓度的丁草胺乳剂并未使三种菌株的回复突变率升高,丁草胺的 Ames 试验为阴性,表明丁草胺无明显的致突变性。
The mutagenicity of butachlor was determined by the Ames test. Salmonella typhimurium strain TA97TA98TA100 as test strains, α-aminofluorene as a positive mutagen. Results The different concentrations of butachlor emulsion did not increase the mutation rate of the three strains, but the Ames test of butachlor was negative, indicating that there was no obvious mutagenicity of butachlor.
