河流污泥中砷的积累及其环境效应的研究

本文以我国大运河(杭州段)为研究对象,系统地分析了不同来源的砷进入河流后的地球化学行为以及砷在河流污泥中的积累过程。通过对河流两侧土壤和地下水中砷的含量分布特征的研究,结合对受砷污染影响区儿童健康的调查资料,讨论了河流污泥中砷的积累对环境的影响,从而为治理受砷污染的河流提供科学依据。

On the Accumulation of Arsenic in the River Mud and its Environmental Effect

With the Grand Canal ( Hangzhou Section ) as an object, the geochiemical behaviour of arsenic after going into the river from different sourqes and the accumualated process of arsenic in the river mud are studied systematically. Based on the study of the feature of the arsenic content distribation of the soil and the underground water on both sides of the river, and combining the investigation data of tne children health in the area affected by arsenic pollution, the effects of the accumulation of arsenic in the river mud on the environment have been discussed, and thus the scientific support for harnessing the river polluted by arsenic is provided.
