三唑磷对四种水生生物的毒性及安全评价研究
Study on toxicity and safety evalution of triazophos on four species of hydrophytic organisms
【摘要】 本文研究了三唑磷对小球藻、卤虫、南美白对虾、泥蚶四种水生生物的急性毒性作用 ,结果显示 ,三唑磷对小球藻的 4 8h的EC50 为 2 4 μg dm3,72h的EC50 为1 5μg dm3;对卤虫的 2 4hLC50 为 1 .6 4mg dm3,4 8hLC50 为 0 .8mg dm3;对南美白对虾仔虾的 4 8hLC50 为 3.2 μg dm3,96hLC50 为 1 .1 μg dm3;对泥蚶的 4 8hLC50 为 2 1 .0mg dm3,96hLC50 为 1 0 .2mg dm3.三唑磷对小球藻、卤虫、南美白对虾为高毒农药 ,泥蚶对三唑磷有很强的耐受力
【Abstract】 The acute toxic effects of triazophos on four species of hydrophytic organisms were stutied.The results showed that 48h EC 50 of triazophos on Chlorella vulgaris was 24 μg/dm 3 and 72h EC 50 was 15 μg/dm 3;24h LC 50 of triazophos on Artemia salina was 1.64mg/dm 3 and 48h LC 50 was 0.8mg/dm 3; 48h LC 50 of triazophos on Penaeus annamei was 3.2μg /dm 3 and 96h LC 50 was 1.1μg/dm 3;48h LC 50 of triazophos on Tegillarca granosa was 21.0mg/dm 3 and 96h LC 50 was 10.2mg/dm 3.Triazophos was highly toxic to Chlorella vulgaris, Artemia salina and Penaeus annamei , but had high endurame to Tegillarca granosa .
