2008—2009年通过对金蛇头入海口及邻近海域海水、表层沉积物的监测,并对环境质量进行初步评价。监测数据结果表明:海水污染物中COD含量仅宁德金蛇头入海口中超出海水水质标准(GB3097-1997)第二类的要求。在无机氮、磷酸盐等项目中宁德金蛇头入海口及邻近海域、对照点站位等海域均超出海水水质标准(GB3097-1997)第二类的要求。而表层沉积物监测项目,宁德金蛇头入海口、邻近海域及其对照站位监测结果均符合海洋沉积物质量标准(GB18668-2002)第一类的要求。

The sdudy evaluated the environmental quality preliminary in 2008-2009 through the supervision for the sea water and surface sediment monitoring of the estuary and adjacent waters in gold smugglers.The results showed that the COD content of water contaminants in the estuary of Ningde gold smugglers exceeded the sea water quality standard GB3097-1997 TypeⅡrequirements,the inorganic nitrogen,phosphate and other projects in the estuary of Ningde gold smugglers and adjacent areas,the control point stations and other waters both exceeded the standards of GB3097-1997 water quality requirements of the second category.The surface sediment monitoring program, the estuary of Ningde gold smugglers,adjacent waters and the control stations to monitor the results were in line with marine sediment quality standards GB18668-2002 the first class requirements.
