福建浮头湾海水及其沉积物的环境质量评价

摘要

2014年12月首次调查了福建浮头湾海域海水及其沉积物的环境质量.结果表明,海水中主要超标污染物为DIN,其含量范围为0.294~0.369mg/L;PO4-P含量符合二类海水水质标准;其它指标均符合一类海水水质标准.研究海域水体已达到富营养化状态,且N为限制性因子.沉积物中各项指标均达到《海洋沉积物质量》(GB18668-2002)的一类标准.%The concentrations of the major environmental items in surface seawater and sediment are reported for the first time in Futou Bay in Fujian Province in Dec 2014.The major pollutant in seawater is DIN,and the concentration is 0.294~0.369mg/L.The content of PO4-P in seawater is with in the First Class Standard of Seawater Quality.The contents of other environmental items in seawater are with in the Second Class Standard of Seawater Quality.It is found that the quality in seawater in Futou Bay was in eutrophication condition using the way of index E,while the limit factor is N.The items in surface sediments are below the values of First Class Standard for Marine Sediments Quality.
