| 摘 要： | 2002年10月江苏省如东洋口文蛤大面积死亡。作者对现场采集的死烂文蛤、近岸海水、滩涂底质3类样品进行检测，并与苴镇、东凌、吕四样品对比分析。发现：(1)洋口死烂文蛤体内有害重金属Cr、Pb、Zn、Cd、As含量比另3处高出数十倍；(2)事发时洋口近岸海水水质与其他水域比较，Zn偏高20倍以上，Cr偏高10倍以上，As亦偏高；(3)洋口滩涂底质中有害重金属含量已接近污染上限。

| Abstract: | The death of Meretrix meretrix in large area in Jiangsu Rudong, Yangkou was ex-amined in October,2002. The samples from dead and decayed Meretrix meretrix bodies were collect-ed and examined. It was found that the contents of Cr,Pb,Zn,Cd and As in the bodies were dozens times higher than those of other three places. Zn and Cr in sence seawater are twenty times and ten times higher than those in other water areas,respectively. The As is higher than normai As in con-tent. In fishery waters,poisonous heavy metai pollution is disastrous in the Yangkou's bottomland. |
