摘　　要：通过对南京上坝水源地的Hg、As、Cu、Pb和Cd的连续自动监测数据进行分析,研究2012年底至2013年上半年南京上坝水源地的重金属的变化情况,并对由重金属所引起的健康风险进行了评价,结果表明:各项所监测重金属含量均能达到生活饮用水标准,并且由重金属引起的健康风险均低于国际辐射防护委员会(ICRP)推荐的通过饮水途径最大可接受风险水平,表明该水体具有较低的健康风险.同时连续1年的发光细菌毒性监测结果也表明该水源地水质处于低毒水平.Heavy metal changes in Shangba drinking water source of Nanjing had been studied since the end of 2012 to the first of 2013, based on the analysis on continuous automatic monitoring data for Hg, As, Cu, Pb and Cd. Health risk caused by heavy metal was evaluated to show that all heavy metal contents monitored could meet the standard of drinking water, and the concerned health risk is at lower level than the maximum acceptable level of risk recommended by international Commission on Radiological Protection （ ICRP）, which means that the water has lower risk. Experimental results on luminescent bacteria toxicity demonstrated that the water source was at safe level.
