春季滨州浅海水域环境质量现状分析及评价

Analysis and Evaluation on the Environment Quality Status in Binzhou Shallow Wayers in Spring

根据2012年春季滨州浅海水域水质监测结果,在内梅罗污染指数法评价的基础上,考虑最大权重因子,采用权重修正的内梅罗污染指数法对该海域水质现状进行了评价和分析。结果表明:滨州浅海水域春季环境质量总体为清洁。在11项评价项目中,DO、COD、铜、铅、砷含量在各调查站位均符合第一类海水水质标准;pH、活性磷酸盐、无机氮、锌、镉指标符合第二类海水水质标准;汞和石油类在部分站位符合第三类海水水质标准,是滨州浅海水域的主要潜在污染因子。

According to the water quality monitoring results in Binzhou shallow waters in spring 2012,the water quality status was evaluated and analyzed by weighting-factor modified Nemerow index meth-od, which based on Nemerow index method and considered the maximum weighting-factor. The resultsshowed that Binzhou shallow waters environment quality was clean in spring. In eleven evaluation iterns, DO, COD, copper, lead, and arsenic reached the first class seawater quality standards in eachsurvey stations; PH, active phosphate, inorganic nitrogen, zinc, and cadmium indexes reached the second class seawater quality standards. Mercury and petroleum reached the third-class seawater qualitystandards in the part of the stations, which was the main potential contamination factor in Binzhou shallow waters.
