摘要
本文用一个简化的健康风险评价模型,对兰村水源地监测到的化学污染物进行了健康风险评价,结论如下:①兰村水源地非化学致癌污染物的健康危害指数远小于1,因此兰村水源地非致癌污染物通过饮食途径不会产生不利于健康的影响。②氟化物是太原市兰村地下水中对人体产生健康危害最大的污染物,但氟化物是天然背景所致。③硝酸盐和亚硝酸盐有可能是人为来源的氨氮进入地下水后氧化所致,应该引起警惕,它们浓度的变化表明人为污染物已经开始进入兰村水源地。
The human health risk was conducted to assess the health risk of pollutants in Lancun Village groundwater supply source of Taiyuan City. The research resuls indicated that ① non-carcinogen pollutants did not have serious detrimental effects to human health.② The hazard quotient of fluoride is the maximal,but fluoride compounds levels in groundwater might come from natural background.③ Nitrate and nitrite compounds in groundwater should be paid attention to,and they might come from artificial pollution sources. This indicated that artificial pollutants could have begun to enter into Lancun Village groundwater supply source.
