摘要
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 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 groundwater containing nitrate content of 12.6～20 mg /L had high risk to human health.
