  • 摘要: 本文以高压汞灯和自然阳光为光源.研究了甲基对硫磷对氯氰菊酯,溴氰菊酯和氰戊菊酯在玻片表面光致降解的影响.结果表明:甲基对硫磷与三种拟除虫菊酯农药混合照光处理后.可使拟除虫菊酯农药的光解速度加快.氯氰菊酯、氰戊菊酯和溴氰菊酯的光解半衰期.在离压汞灯下比单独照光分别缩短12.18.8.46和7.33倍.在阳光下则分别缩短1.73,2.65和4.46倍.甲基对硫磷对三种拟除虫菊酯农药表现出显著的光敏降解作用.且其光敏效率与甲基对硫磷的剂量成正相关.
    Abstract: The effects of parathion-methyl on photolytic rates of cypermethrin, deltamethrin, and fenvalerate on glass were studied with 150W high pressure mercury lamp or under sunlight. The results showed that by mixing with parathion-methyl, the photolytic rates of three pyrethroids were accelerated significantly; and the half-life of cypermethrin, fenvalerate, and deltamethrin were shortened by 12.18, 8.46, and 7.53 times respectively under high pressure mercury lamp,and by 4.73,2.56,and 4.56 times respectively under sunlight. There was significant positive correlation between the dosage of parathion-methyl and the photosensitive efficiency.
