摘要
采集江苏省沿海30处主要入海河口断面水样,分析TN、NH3-N、TP、pH值等污染指标,分别利用单因子污染指数法和内梅罗综合污染指数法对水质现状进行评价和分析,以确定污染程度和主要污染物。结果表明:江苏省90%的入海河口断面水质无法满足GB 3838—2002《地表水环境质量标准》中的Ⅲ类水标准,其中63%的断面为轻度污染,27%的断面为中度污染,主要污染物为TN和TP。
Water samples were collected from 30 main estuaries in Jiangsu Province and the main pollution indexes （TN,NH4^＋ -N, TP and pH value） were analyzed. The water quality conditions were assessed with a single factor pollution index method and the Nememw comprehensive pollution index method in order to characterize the pollution degree and the main pollutants. The results indicated that the water quality in 90% of the estuaries does not meet Class III water quality standards according to the Environmental Quality Standards for Surface Water in China. 63 % of those estuaries were slightly polluted and 27 % were moderately polluted. The major pollutants were TN and TP.
