| 摘 要： | 环境中农药的污染残留问题备受社会关注,尤其是食品安全这一方面.作为世界上有机磷农药(OPPs)生产和使用的大国,国内环境中OPPs的残留赋存问题尤其受到重视.残留在环境中水体、土壤、生物体的OPPs可能经口、皮肤接触、呼吸等暴露途径进入人体对人体健康造成风险.了解OPPs在国内主要江河湖泊、土壤、生物体中的残留赋存情况并进行风险评价至关重要.本文对比总结了中国环境中水体、土壤、生物体中主要OPPs的含量范围、检出率及其分布特征,并利用美国RBCA健康风险评价模型对其进行健康风险评价和RQ商值法进行水生生态风险评价.结果显示,中国地表水体含量最高的5种OPPs分别是敌敌畏、乐果、对硫磷、马拉硫磷、甲基对硫磷,浓度变化范围ND—30180 ng·L-1,北方水体的OPPs污染状况水平要高于南方水体.OPPs风险评价结果显示,地表水、土壤、蔬菜中OPPs的非致癌风险系数(HQ)分别为7.25×10-5—6.93×10-1、9.56×10-7—5.30×10-2、1.08×10-2—7.01×10-1,都还未超过1的安全标准,对人体健康不会产生明显的不良影响.地表水中敌敌畏的致癌风险系数(R)范围为2.86×10-8—6.25×10-6在10-5—10-6安全范围内.对比地表水、土壤、蔬菜的HQ值,蔬菜中残留的单体OPPs对人体的健康风险大于地表水和土壤,水生生态风险评价结果中OPPs对糠虾和水蚤RQ值>1,处于高风险.
