象山港重金属的环境化学特征

Environmental chemical characteristics of the heavy metals in Xiangshan Bay

本文根据１９９０年６月和１１月对象山港海域进行的综合环境（水文、生物、化学）调查资料，分析了水体（包括溶解态、颗粒态）和沉积物的重金属（Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ｃｒ）含量，运用元素的分布规律，探讨了该区的水动力因素、生物地球化学循环和沉积环境对重金属的影响，初步揭示了象山港重金属的环境化学特征。

The comprehensive environmental investigation (hydrology, biology and chemistry) in Xiangshan Bay sea area had been carried out on June and November, 1990. The contents of the heavy metals (Cu, Pb, Zn, Cd, Cr) were analysed in the waterbody (including dissolved and particulate forms) and in the sediment. By using the distribution rule of elements in seawater environment, the influnces of water dynamic facter, biogeochemical cycle and sedimentary environment on the heavy metals in the area were discussed, and the environmental chemical characteristics of heavy metals in Xiangshan Bay was initially showed.
