镉作为一种对人体有害的微量物质进入环境,愈来愈引世界各国的关注。目前国内对微量危害的研究有不少报道,内容多限于各种类型的工业污染方面。本文主要是通过贵州赫章铅锌矿区的剖析,探讨在矿区自然环境中,镉的环境地质地球化学与人群健康的关系。一、矿区环境的地质背景矿区属铅锌砂矿床类型,铅锌矿砂即为第四纪的坡积物和冲积物,面积约2平方公
Cadmium as a trace of harmful substances into the environment, more and more countries all over the world attention. At present, there are many reports on the study of trace hazards in China. The contents are mostly limited to various types of industrial pollution. This paper mainly through the analysis of lead-zinc mining area in Hezhang, Guizhou, to explore the relationship between the environmental geo-geochemistry of cadmium and the population health in the natural environment of the mining area. I. Geological Background of the Mining Area The mining area belongs to the type of lead-zinc sand deposit. Lead-zinc ore is the Quaternary sediments and alluvial deposits with an area of about 2 square kilometers
