| 中文摘要 |
| 应用甲胺磷农药对土壤动物进行污染模拟实验。结果表明,甲胺磷农药对土壤动物有明显影响,并随着甲胺磷溶液处理浓度的增加,土壤动物的种类和数量显着减少;多样性指数,高处理浓度(0.54ml/L)时为3.7596,低处理浓度(0.01ml/L)时为5.7962,对照组则为8.5714.大型土壤动物蚯蚓的染毒实验表明,甲胺磷对蚯蚓有明显的致死作用,其半致死浓度(LC50),24h为13.7ml/L,48h为5.4ml/L,72h为3.9ml/L,计算所得蚯蚓生活的安全浓度为0.2517ml/L。 |
| 英文摘要 |
| Results of simulating experiments on methamidophos pesticide to soil animals showed that the methamidophos pesticide has an obvious effect on soil animals,the species and the amount of soil animals decrease obviously with increasing of methamidophos pesticide treating concentration;the diversity indexs are 3.7596,5.7962 and 8.5714 for 0.54ml/L,0.01ml/L and control of methamidophos pesticide treating concentration respectively.Toxicity test of earthworm showed that the methamidophos pesticide influences obviously earthworm,their LC50 are 13.7ml/L,5.4ml/L and 3.9ml/L for 24 hours,48 hours and 72 hours respectively.Safe concentration calculated of earthworm living is 0.2517ml/L. |
