| 摘 要： | 于2005年9月对罗源湾海水、表层沉积物和生物体中重金属Cu、Pb、As、Hg、Zn、Cd的含量及分布情况进行了调查,并运用单因子指数法进行现状评价.结果表明:海水各重金属浓度符合海水水质二类标准,均小于渔业水质标准,同1986年的调查结果相比较,各种重金属的浓度都有所增加;表层沉积物中重金属的含量基本上符合海洋沉积物质量一类标准;生物体中重金属的含量除牡蛎Cd严重超标外,其余均符合无公害水产品的要求.

| Abstract: | The concentration and distribution of heavy metals Cu,Pb,As,Hg,Zn,Cd in seawater,surface sediments and several marine organisms of Luoyuan Bay were studied in Sep.of 2005.The ecosystem was evaluated by the single factor index method.The results show that the heavy metals pollution levels in seawater in Luoyuan Bay are not beyond the national benchmark of the second-class of seawater quality,and are much lower than the fishery water quality standard.Compared with the investigation data of 1986,the heavy meta... |
