摘要
根据2008～2009年宁波地区滩涂贝类养殖区养殖环境和贝类生物质量趋势性监测的资料，对象山港和三门湾几个主要贝类养殖区的表层沉积物、水质和三种养殖贝类（僧帽牡蛎、缢蛏、泥蚶）的五种重金属含量进行测定，并对其产品质量安全进行评价。海水重金属检测结果均低于《渔业水质标准》，但Pb含量超过《海水水质标准》中的一类标准。沉积物中Cu平均含量超过海样沉积物一类标准，其他重金属均低于海样沉积物一类标准，但基本上均高于背景值。通过对照水产品质量标准，宁波地区滩涂养殖贝类泥蚶Cd严重超标，僧帽牡蛎中Cu和Cd也超标严重，应引起有关部门的重视。
Based on the date of environmental surveyed and cultured shellfish obtained from the tidal shellfish cultured areas of Ningho in 2008 - 2009, the concentrations of five heavy metals in surface sediments, sea water and the three species of shellfish （ Tegillarca grartosa, Sinonovacula constricta ,Saccostreae cucullata） in Xiangshan Bay and Sanmen Bay were detected and analyzed. The contents of heavy metals in sea water were all bellow the Fisheries Water Quality Standard, but the content of Pb was higher than the Water Quality Standards. The average contents of Cu in sediments were higher than the values of the first degree of Oceanic Sediments Quality. The average contents of other heavy metals were lower than the values of the First Degree of Oceanic Sediments Quality, but essentially higher than the background value. Comparing the content of heavy metals in aquatic products with Aquatic Quality Standards, It was found that the content of Cd in Tegillarca granosa of Ningbo was far exceeded, so the content of Cu and Cd in Saccostrea cucullata should he paid the attention by the relative departments.
