铅锌矿区土壤镉污染初步研究

INITIATORY STUDY OF THE POLLUTION OF CADMIUM IN SOIL IN Pb-Zn MINING AREA

以广西某铅锌矿开发引起的土壤镉污染为例，阐述含镉化合物在河流水体中迁移与沉淀的基本特征；土壤中镉的存在状态及其与其它金属元素的相关性。土壤镉污染导致谷物、蔬菜、牲畜和家禽的镉污染；饮水和食物的镉污染通过食物链引起镉中毒疾病的发生。在被污染的土壤中种植某些植物，可消除土壤镉污染。

This is an example for the soil pollution of cadmium induced by exploitation of Pb-Zn ore.The treatise describes the basic feature of the migration and the precipitation of cadmium compound in the steam, the correlation between the form of cadmium and other metallic elements in the soil, the crop absorption of cadmium and the aggergation of cadmium in the soil, the pollution of cadmium in the drink water and the food and the poison of cadmium in the human body arouse to the disease and the elimination of the polliution of cadmium by the plant absorption.
