| 摘要: |
| 本文报告了黄河口水中悬浮体和沉积物中汞的含量及分布。结果表明黄河人海河段没有受到沿岸排污影响。黄河挟带的大量颗粒物质是汞的主要载体。黄河丰水期水体中总汞含量比相应枯水期高。沉积汞含量的分布表明汞含量与沉积类型有关。 |

| THE DISTRIBUTION OF MERCURY IN ESTUARY OF YELLOW RIVER |
|
|
| Abstract: |
| The distribution of mercury in estuary of Yellow river has been studied. Mercury contents in the samples taken from river and estuary in May--November 1984, were determined by Cold--Vapoar atomic fluorescence spectrometry. The results indicate that the total and partical mercury in the river were generall higher than that in the estuary and in the river and August were higher than May. The horizontal distribution of mercury shows that the main strea of yellow river flowing into the sea has the nighest values in estuary of yellow river. The range of concentration of mercury in sediments in the river varied from 0.013 to 0.033μg/g and in the estuary varied from 0.005 to 0.028μg/g. |
