高尔夫球场农药向大气中的挥发研究

高尔夫球场喷洒农药向大气中的挥发受农药性质、施药方式和环境条件的影响。用丙酮、二氯甲烷等有机溶剂作吸收液可较好地捕集空气中的氯氰菊酯、毒死蜱、百茵清等农药化合物。试验条件下，2，4-D丁酯、百菌清和氯氰菊酯在大气中的挥发损失率分别为6．31％、1.38％、7．20％，毒死蜱和灭多威的挥发损失率为0．78％和1．66％。相比之下，氯氰菊酯较易挥发，对空气的污染较大。选择性用药，采用颗粒剂撒施，可有效地减少农药挥发，有利于环境保护。

Study on Volatilization Behavior of Pesticides in Golf Course

The volatilization behavior of application methods under the special pesticides was affected by pesticide properties and environmental condition. The pesticides such as cypermethrin, chlorpyrifos and chlorothalonil could be well enriched by the organic solvent such as acetone and dichloromethane. Under the test condition, the volatilization rates of 2,4-D butyl, chlorothalonil and cypermethrin in air were 6.31%, 1.38% and 7.20% respectively. Nevertheless, the volatilization rates of chlorpyrifos and methomyl were 0.78% and 1.66% respectively. In contrast, cypermethrin lead to air pollution easily because of high volatility. It was benefit to environmental protection when the suitable pesticides and formulations were well chosen.
