介绍了土壤和水样中毒死蜱农药残留的测定方法 ,并应用该方法调查了某地高尔夫球场使用毒死蜱农药后对周围土壤和地表水的污染影响。测定结果表明 ,在调查区范围内 ,地表水中毒死蜱农药的浓度小于 0 .4μg/L。参照国外有关标准 ,它低于美国健康与福利部 (MHW)制定的高尔夫球场饮用水中允许的残留值 (毒死蜱 :4μg/L )。
The method for determining the pesticide residues of chlorpyrifos in soil and water samples was introduced. The method was used to investigate the effect of chlorpyrifos pesticide on the soil and surface water pollution in the surrounding golf course. The results showed that the concentration of chlorpyrifos pesticides in surface water was less than 0.4μg / L within the survey area. Reference to foreign standards, it is lower than the United States Department of Health and Welfare (MHW) to establish the allowable residual value of the golf course drinking water (chlorpyrifos: 4μg / L).
