摘　　要：根据2010—2013年对浙江舟山2个污水处理厂排污口邻近海域14个站位的表层海水铜、铅、锌、镉、砷、总铬、总汞、p H值、无机氮、活性磷酸盐、石油类、化学耗氧量、悬浮物和粪大肠菌群等14项污染因子的调查,采用单因子指数法和营养指数法对监测海域海水水质进行评价。结果表明,舟山污水处理厂排污口邻近海域表层海水质量总体良好,基本符合第二类海水水质标准;主要污染因子为无机氮、活性磷酸盐和悬浮物,其他水质指标则较低;2个污水处理厂排污口邻近海域海水均呈高富营养化状态,并受到一定程度的铅污染。In 2010-2013,14 pollutants,including Cu,Pb,Zn,Cd,As,total Cr,total Hg,pH, inorganic nitrogen,active phosphate,oil,COD,SS,and fecal coliform were monitored in 14 spots of surface sea adjacent to outlets of 2 sewage treatment plants of Zhoushan,Zhejiang. The result showed that,as a whole,the seawater quality in the monitoring area was good,in compliance with the sec-ond standard of sea water quality basically. The major pollution factors were inorganic nitrogen,ac-tive phosphate and suspended solids,and other index were in good level. The two sea areas were in the state of eutrophication,suffering from Pb pollution in some degree.
