淤泥和土壤中Cd、Cu、Zn的结合形态研究

Research on the Chemical Forms of Cd, Cu, Zn in Silt and Soil

本文首次研究了京杭大运河(杭州段)的淤泥、底泥及其旁侧土壤中Cd、Cu、Zn存在的形态特征,对阐明运河体系的环境地球化学行为特征,研究环境容量均具有重要意义。同时,对运河的环境污染的综合防治提供了重要的科学依据。

It is first time that the characteristics of the chemical forms of Cd, Cu, Zn in silt, bottom mud and soil near the bank of Beijing-Hangzhou Canal (Hangzhou section) has been studied. This study has very practical significance on the expoundment of the environmental geo-chemistry characteristics and the environmental capacity in the canal system; simultaneouly, it has provided the important science basis on comprehensive control of environmental polluttion in the canal.
