作者调查了长江口东部海域水相、悬浮相和沉积物中铜的含量分布及其地球化学特征。根据分析结果可将所调查的海域分为区域Ⅰ(近岸河口区)和区域Ⅱ(远岸外海区)。两区的悬浮物和沉积物具有不同的来源,区域Ⅰ主要为长江的输出物,区域Ⅱ主要由苏北沿岸流带入。前者的酸可溶相部份明显地大于后者,这反映了长江口沉积物受排污的影响较大。 The authors investigated the copper content distribution and its geochemical characteristics in the water, suspended sediments and sediments of the eastern estuary of the Changjiang Estuary. According to the results of the analysis, the waters under investigation can be divided into Zone I (nearshore estuary) and Zone II (offshore of the far coast). There are different sources of suspended matter and sediment in the two areas. Region I is mainly the output of the Yangtze River, and region II is mainly brought in by the littoral of northern Jiangsu. The former part of the acid-soluble phase is significantly larger than the latter, which reflects the Changjiang Estuary sediment affected by the sewage more.
