嘧霉胺对环境生物毒性及安全评价

Toxicity and Safety Evaluation of Pyrimethanil on Environmental Organisms

测定了嘧霉胺农药对6种有代表性的非靶生物蜜蜂、鹌鹑、家蚕、斑马鱼、泽蛙、蚯蚓的急性毒性,并进行了安全性评价。试验结果表明:嘧霉胺对蜜蜂接触LD50(48 h)>100μg/蜂,经口LC50(48 h)>1333 mg/L,对雌、雄鹌鹑LC50(7 d)>1000 mg/kg,对家蚕、斑马鱼、泽蛙的LC50(96 h)分别为727、25.1、27.7 mg/L,对蚯蚓LC50(14 d)为206 mg/kg干土。该农药对蜜蜂、鹌鹑、家蚕、斑马鱼、泽蛙、蚯蚓毒性均为低毒级。

This paper tested the acute toxicity of Pyrimethanil to six representative no - drones biology （ bee, partridge, silkworm, zebra fish, marsh frog and earthworm）, and evaluated their safety. The result of the experiment showed that the stomach toxicity LC50 （48 h） of Pyrimethanil to bee was higher than 1333 mg/L, the contact toxicity LD50（48 h） to bee was higher than 100 μg/bee; LC50 （7 d） to male and female partridge was larger than 1050 mg/kg; LC50 （96 h） to silkworm, zebra fish and marsh frog was 727, 25.1, 27.7 mg/L respectively; LC50 （ 14 d） to earthworm was 206 mg/kg. This germicide was low - toxic to bee, partridge, silkworm, zebra fish, marsh frog and earthworm.
