摘  要：
根据2001-2005年天津近岸海域水质监测数据,对重金属含量随时间尺度发生的变化进行了分析,结果表明:2004年重金属Cu的含量最高。检测的5 a中,2004年的重金属Zn,Pb污染最为严重,到2005年时污染得到了有效控制;在这5 a中,Pb含量的波动很大,受到严重的人为干扰。2001-2005年Ⅰ类海水Cd的含量最大,污染最为严重并且变化不显著,需要加强治理;重金属Hg在Ⅰ类海区的污染状况与Cd类似。

摘  要：
Bohai Sea is the largest inland sea in china,and Tianjin coast is developed coastal areas,but the economic development have had a great impact on ecological environment of the sea.Heavy metals in marine organisms can be enriched through the food chain,and ultimately harm human health.This paper monitored data on heavy metal content with time-scale changes,studied heavy-metal contamination,The results are as follows: the content of heavy metal Cu is the highest in 2004;the Zn content in 2004 was also the highest,and there is a significant difference between 2004 and 2005,the pollution has been effectively controlled in 2005;Pb content are declining from 2004 to 2005,and there was a significant differences.In this five-year period the content of Pb was volatile,with serious human disturbance;2001-2005 Class 1 water Cd content had the most serious pollution problem and did not significantly change,this need to strengthen fisheries management so as to achieve the requirements.2001-2005 heavy metal Hg and Cd existed the same problem in Class 1 water,Class 1 water are the most serious pollution area,need to find a precise pollution sources,so that change water quality as soon as possible.
