| 摘 要： | 以某高原湖泊为例,以湖水中的砷含量类比推算了从该湖泊取水灌溉区域内水稻和蔬菜的砷含量,对稻米、蔬菜和饮水3种暴露途径进行健康风险评估。结果表明,人群通过摄入区域内稻米、蔬菜的致癌风险系数为可接受的致癌风险,饮用湖水的致癌风险系数为不可接受的致癌风险。

| Abstract: | Taking a plateau lake as an example,we measured the arsenic concentration of the lake water,got the arsenic content in irrigated rice and vegetables by analogy method,took the health risk assessment on the exposure of rice,vegetables and drinking water.The results showed that the Carcinogenic Risk Index for ingestion from local rice and vegetables are acceptable carcinogenic risk level,but the drinking water is at an unacceptable carcinogenic risk level. |
