| 摘 要： | 河口砷(As)的地球化学行为的研究是近几年才开始的。Waslenchuk和Windon在研究美国东南部一些河口砷的行为时,认为砷在河口的行为是保守的。Howard在调查英格兰南部的Beaulieu河口砷的行为时,发现有转移的迹象。黄河口及其近岸海域溶解砷的调查目的是想了解砷在黄河口的行为及其分布特征。

DISSOLVED ARSENIC IN THE YELLOW RIVER ESTUARY AND THE ADJACENT COASTAL ZONE |
| |
| Abstract: | Dissolved arsenic in the Yellow River Estuary and the adjacent coastal Zone was determined in May, August and November, 1984. The following results were obtained: 1. The content of dissolved arsenic in the region of the Yellow River Estuary was lower than that of both Yellow River and the Bohai Sea waters in May. Further study would be necessary in order to understand the cause for this. 2. In August the content of dissolved arsenic in the region was higher than that responding to theoretical dilution line. It might be due to 1) the release of arsenic in association with hydrated oxides of iron and manganese from sediments to water and 2) typhoon which makes it distribute to the whole water column. 3. Distribution of dissolved arsenic in the region surveyed was considerably uniform in November, 1984. 4. The flow of dissolved arsenic from the Yellow River to the Bohai Sea was about 82.5 tons in the year 1984. |
