沈家门渔港附近海域环境中重金属的调查和评价

Investigation and Evaluation of Heavy Metals in the Sea Environment Near Shenjiamen Fishing Port

本研究通过调查分析2021年春季浙江沿海典型渔港沈家门渔港附近海域渔业环境水质、沉积物中重金属铜、铅、锌、镉、汞、砷等含量,获得相应的水质和沉积物中重金属参数数据,为浙江沿海城市发展海洋渔业等相关产业提供数据支持,为居民健康饮食提供理论依据。本次调查研究共设6个海水水质站位和6个海洋沉积物站位,调查结果显示沈家门渔港附近海域水质符合《海水水质标准》中第一类海水水质标准的要求,该评价海域沉积物符合《海洋沉积物质量》第一类评价标准的要求。

By investigating and analyzing the water quality of the fishery environment and the contents of heavy metals such as copper,lead,zinc,cadmium,mercury and arsenic in the sediments near Shenjiamen fishing port,a typical coastal fishing port in Zhejiang Province in the spring of 2021,this study obtains the corresponding parameter data of water quality and heavy metals in the sediments,provides data support for the development of Marine Fisheries and other related industries in coastal cities of Zhejiang Province,and provides a theoretical basis for residents’ healthy diet.There are 6 seawater quality stations and 6 marine sediment stations in this investigation and study. The investigation results show that the water quality of the sea area near Shenjiamen fishing port meets the requirements of class I seawater quality standard in the seawater quality standard,and the sediments in the evaluated sea area meet the requirements of class I evaluation standard in the marine sediment quality.
