关中盆地浅层地下水氮污染的健康风险评价
Health risk assessment of "Three Nitrogen" in shallow groundwater in the Guanzhong Basin
摘要
Abstract
In order to investigate the risk of healthy hazards to human beings caused by “Three Nitrogen” in shallow groundwater in the Guanzhong Basin, 232 water samples were gathered and detected. Based on the method of one-factor pollution index and the model of water environmental health risk assessment, the pollution degree and health risk in the study area were analyzed. The results show that the nitrate content was significantly higher than the content of ammonium nitrogen and nitrite. The nitrate presents the face-shaped pollution form in shallow groundwater, and the ammonium nitrogen and nitrite present point pollution form.The health risk assessment results show that the nitrate non-carcinogenic chronic toxic index for human health' was relatively high in shallow groundwater of the study region. The high risk region occupied 78.2％ of the total study area, which occurred chiefly in the irrigation area and town with dense-residence and advancedindustry. The groundwater containing nitrate content of 12.6 ～ 20 mg/L had high risk to human health. The previous conclusions were proposed as important references for management and protection of the groundwater resources.关键词
