摘要(Abstract)：

在海南省松涛水库采集了鱼类和螺蛳共34个样品,利用气相色谱-质谱联用仪(GC-MS)检测样品中农药的浓度,并根据美国环境保护署(US EPA)的健康风险评价模型对松涛水库周围人群通过饮食途径摄入水生生物进行健康风险评价。结果表明,检测的29种农药,仅有7种在大部分样品中检出,分别为2,4-DDE、4,4-DDE、2,4-DDD、4,4-DDD、4,4-DDT、甲氧滴滴涕和甲基对硫磷,它们的平均含量(以湿重计)分别为0.32 ng·g~(~(-1))、3.68 ng·g~(~(-1))、0.17 ng·g~(~(-1))、1.33 ng·g~(~(-1))、0.90 ng·g~(~(-1))、1.34 ng·g~(~(-1))、0.32 ng·g~(~(-1))。鱼类肌肉以及螺蛳肉中农药的健康风险评价远远低于可承受水平,表明食用这些鱼类与螺蛳所造成的健康风险比较低。与其他研究相比,松涛水库的农药污染程度较轻。造成不同生物体间的农药含量差异的主要原因可能是牙叉库区的农药污染比南丰和番加库区的污染严重。
