福建省海岛水体和底质中的重金属含量

Contents of Heavy Metals in Water and Sediment around Islands in Fujian Province

通过对福建省海岛水体和底质中Hg、Cu、Pb、Zn和Cd的分析,结果表明:水体中溶解态和颗粒态的Cu、Pb、Zn和Cd没有超标。底质中的Cu、Pb和Zn有部分海岛超标;初步认为,海岛周围水体和底质中的重金属含量与福建省陆地普遍存在的铅锌矿有关。

Hg, Cu, Pb, Zn and Cd in water and sediment around islands in Fujian have been analysed. The results indicate that dissolved and granulated Cu, Pb, Zn and Cd in water are up to the standard. Around some islands, Cu, Pb and Zn in sediment are beyond the standard, and this is thought to have relation to the widespread existence of lead and zince on the land of Fujian.
