在分析南湖水质的基础上，对重金属进行Pearson相关性分析，并进行了健康风险评价。结果表明Cr、Cu、Zn未超过生活饮用水卫生标准，Cd 和Pb严重超标。 Cu、Zn、Cd、Cr污染存在一定的同源性，而Mn、Fe、Ni、Pb污染具有多源性。污染物通过皮肤接触途径造成的危害要远小于饮水途径，致癌物风险比非致癌物高1～8个数量级，其中Cd对总风险贡献率为62.16％，成为主要的风险污染物。8个监测点都检测到致癌物，且风险度高于可接受水平，应引起环境治理部门的关注。

Partial correlation is analyzed based on water quality.Health risks associated with heavy metals in drinking water are assessed.The results show that Cr, Cu and Zn do not exceed drinking water health standards, while Cd and Pb are severely over the limit.Correlation analyses demonstrate that Cu, Zn, Cd and Cr are from same sources, while Mn, Fe, Ni and Pb are from different sources.Compared with ingestion exposure route, the harm caused by contaminants exposure through dermal contact route is far less.Carcinogenic risks for carcinogens are 1~8 orders of magnitude higher than non-carcinogens.Cd is the main risk pollutant as a result of the contribution rate of it for total risk was 62.16%.Carcinogens are detected at 8 monitoring points. It is considered that South Lake of Siping city should be concerned by environmental management departments since total health risk of it far exceeds the reference value.
