鸭绿江口汞的污染状况及其防治对策

A Research of Pollution Situation of Hg in the Yalu River Estuary and its Control Countermeasures

本文以对鸭绿江口水中（ 原水与过滤掉悬浮物） 、沉积物中以及１６ 种鱼鱼体中Ｈｇ 含量的实测结果，阐明了鸭绿江口Ｈｇ 的污染状况，在找出该江口Ｈｇ 的主要污染源的基础之上，提出三项Ｈｇ 的污染防治对策，以其中的Ｈ２Ｓ除Ｈｇ 的实验结果。

Based upon the experimental results of Hg Concentration in water(raw water and filtered water),sediments and 16 kinds of fishes, the situation of Hg in the Yalu river’s estuary has been demonstrated in this paper.On the basis of the evaluation of the largest pollution source of Yalu River Basin, three control countermeasures were proposed. From the experimental results of Hg removal by H 2S method, the technological and economic feasibility were described.
