本文对新农药复硝钠的急性毒性、蓄积毒性和致突变性进行了研究。试验结果表明,复硝钠属低毒农药,在动物体内的蓄积性比较低。通过Ames试验、小鼠骨髓细胞微核试验和精子畸变试验的结果可以看出,复硝钠没有导致基因突变而改变体细胞和生殖细胞中的遗传信息,故未出现诱变作用。 In this paper, acute toxicity, accumulative toxicity and mutagenicity of new pesticide sodium selenite were studied. The test results show that sodium hypochlorite is a low toxicity pesticide, which has a low accumulation in animals. Through the results of Ames test, micronucleus test of bone marrow cells and sperm aberration test in mice, it can be seen that sodium hypophosphite did not cause genetic mutation and changed the genetic information in somatic and germ cells, so there was no mutagenic effect.
