中文摘要：

采用单因子污染指数法、内梅罗综合指数法和健康风险指数法评价了连云港市区地下水污染状况和健康安全性,探讨了地下水污染防治措施与对策。结果表明,新浦区的NO2-介于Ⅰ类和Ⅱ类水之间,其他3个区的NO2-均在Ⅲ类和Ⅳ类水之间;海州区的NO3-处于Ⅳ类水质,其他3个区的NO3-均是Ⅲ类水质;4个区的挥发性酚质量浓度处在Ⅳ类水质;其他污染物和10种重金属离子几乎都处于Ⅰ类和Ⅱ类水质之间。综合评价认为,新浦和连云区的地下水属于轻微污染水平,海州和开发区的地下水属于中等污染水平;4个区的10种易致癌污染物中的NO2-,Cr6＋和Pb的年健康风险较大,危害指数较高,在饮用地下水时都存在一定的风险性。

英文摘要：

The single-factor pollution index,hazard index and Nemero composite index methods were chosen to evaluate the groundwater in Lianyungang City,hoping to find the corresponding controlling measures.Results showed that NO2-at Xinpu district was between grade Ⅰand Ⅱ,whereas those at the other three districts were between grade Ⅲ and Ⅳ.NO3-at Haizhou district was in grade Ⅳ and those at the other three districts,Grade Ⅲ.Volatile hydroxybenzene contents were Grade Ⅳ,other pollutant and 10 metal ions were between grade Ⅰ and Ⅱ.The groundwater pollution at Xinpu and Lianyun districts was slight,while that in Haizhou and the Developing Zone was serious.Among the 10 carcinogenic pollutants,NO2-,Cr6＋ and Pb are most hazardous to people＇s health.
