溴氟菊酯对环境生物的安全评价研究

Safety Evaluation of Brofluthrinate to Environmental Organisms

按照“化学农药环境安全评价试验准则”的规定 ,测定了溴氟菊酯对 7种环境生物的毒性。结果表明 :其对鸟类、蜜蜂和蚯蚓的毒性较低 ;对鱼类属中等毒性 ;对类、藻类和家蚕属高毒性。由于溴氟菊酯用量少 ,在环境中降解快 ,因此在田间使用时对水生生物的实际危害要小得多 。

The toxicities of brofluthrinate to 7 species of environmental organisms and their safety evaluation were studied, according to “Experimental Guideline for Environmental Safety Evaluation of Chemical Pesticides” [1] . The results showed that the toxicity of brofluthrinate to birds, bees and earthworms is low, to fish is medium, and to Daphnia, alga, silkworms is high. The actual harm to the aquatic organisms is very low when used in the fields, because of the little dosage and quick degradation. But the pollution to the nearby mulberry must be strictly prevented so as not to influence the growth of silkworms.
