摘要
采用固相萃取-GC-MS法对杭嘉湖地区16个集中式饮用水源水体中32种有机磷、有机氯农药进行了分析检测.结果表明,16个集中式饮用水源水共检出16种有机农药,,在平水期、丰水期、枯水期,被检出的有机农药种类分别为7种、1种和15种,表明水体中有机农药种类和浓度的季节性变化较明显,枯水期检测到的有机农药种类最多,浓度相对较高.
Water samples were collected from 16 drinking water sources of Hangjiahu Area, and concentrated by solid-phase extraction and then GC-MS was used to analyze the concentration of organophosphorus pesticides （OPPs） and organochlo- rine pesticides （ OCPs）. The results showed that a total of 16 kinds of OPPs and OCPs were detected in the range of 0.01 -30.18 ~g/L, with the detection rate of 4-54%. The detection rate of dimethoate and parathion-methyl is higher than 50%. In low, mean and high water season, the kind of determined compounds is 7,1 and 15 ,with the concentration range of 0.01 - 2, 25 μg/L, O. 06 - 2.00 μg/L and 0. 01 - 30.18μg/L.
