| 摘 要： | １９９８年３月、７月、１０月，在对上海潮滩进行连续采样和观测的基础上，用原子吸收法测试了７０个沉积物中的Ｃｕ，Ｐｂ，Ｚｎ，Ｃｄ．Ｃｒ的含量。结果表明：（１）上海潮滩重金属含量有如下顺序：Ｚｎ〉Ｃｕ〉Ｃｒ〉Ｐｂ〉〉Ｃｄ。（２）从高潮滩到中低潮滩，重金属的含量递减。（３）不同的采样位置对重金属的含量有显著影响。（４）由于季节的变化，重金属元素的含量变化的幅度也很大，就现有三个季度数据对东海农场进行统计

| Abstract: | Based on the successive observation of Shanghai tidal flat,70 surface sediment samples were collected in March,July and October of 1998 respectively. The concentrations of Cu,Pb,Zn,Cd and Cr in sediments were analysed by atomic absorption spectrometry. The results show that heavy metals of Shanghai tidal flat were found in the following order :Zn>Cu>Cr>Pb>>Cd and heavy metals tended to be decreased form high tidal flat to middle-low tidal flat. The concentrations were varied with different sampling sites. Seasonal changes significantly influence concentrations of Cu while Cd was not been observed. Compared with sediment criteria,the heavy metals pollution mainly are Cu Pb and Zn. |
