[目的]明确氯胺嘧草醚(开发代号ZJ1835)对环境生物的安全性,开展了该药剂对鹌鹑、斑马鱼、家蚕、蚯蚓、蜜蜂和赤眼蜂的安全性评价试验。[结果]氯胺嘧草醚对鹌鹑的LD_(50)值为>1000 mg a.i./kg体重;对斑马鱼、家蚕和蚯蚓的LC50值分别为>100 mg a.i./L、1138 mg a.i./L和>101 mg a.i./kg干土;对蜜蜂急性经口毒性和接触毒性为8080μg a.i./蜂、>100μg a.i./蜂;对赤眼蜂的安全系数为>7.4。[结论]该药剂对上述6种环境生物的安全性评价结果均为低毒或低风险性,对环境安全性好。
[Objective] The research aimed to clarify the safety of chlorimuron-ethyl (code: ZJ1835) to environmental organisms and carried out the safety assessment of quail, zebrafish, silkworm, earthworm, bee and Trichogramma. [Result] The values of LD 50 for quail were> 1000 mg ai / kg body weight for quails and> 100 mg ai / L and 1138 mg ai / L for zebrafish, silkworm and earthworm, respectively > 101 mg ai / kg dry soil; acute oral toxicity and contact toxicity to bees is 8080 μg ai / bee,> 100 μg ai / bee; safety factor to Trichogramma was> 7.4. [Conclusion] The safety evaluation results of the agent on the above six kinds of environmental organisms were both low toxicity or low risk and good to the environment.
