【摘要】 根据1987年3月至1988年12月九龙江口、厦门西港海域的调查资料,初步探讨该海域Fe、Mn、Cu、Zn、Ni、Co、Pb、Cd 等重金属元素的生物地球化学特性,及其与磷的生物地球化学的关系。结果表明该海域重金属元素的分布主要受九龙江径流的影响。在河水与海水混合过程中,悬浮颗粒态重金属元素发生明显转移,Fe、Mn、Co、Zn 等元素自悬浮颗粒物上解吸,Cu 可能被吸附。颗粒态重金属元素与颗粒态磷呈良好的正相关关系。浮游植物体内的重金属元素与颗粒态重金属元素呈正相关关系。浮游植物对重金属元素有一定的富集作用,Fe、Cu 的富集系数较大。更多还原

【Abstract】 The biogeochemical features of heavy metals(Fe,Mn,Cu,Zn,Ni,Co,Pb,Cd)is dis-cussed based on the survey data from the Jiulong River Estuary and Western Xiamen Har-bour during March,1987 and December,1988.The distribution of heavy metals in the areasare under the influence of the Jiulong River runoff.In the mixed process between river andseawater,the tranfer of heavy metals in suspended particles clearly occurs in correspondencewith the deposition and sedimentation of particulate phosphorus.In this mixed process Fe,Mn,Co and Zn are disadsorbed from the suspended particulate matters,as well as phospho-rus,but Cu may be enriched. There is a significant correlation between heavy metals andphosphorus in suspended particles respectively.The positive correlations between heavy met-als in suspended particles and those in phytoplankton are found in the areas.Fe and Cu areenriched on the phytoplankton with larger enriching coefficient.更多还原
