摘要
采集矿山尾矿堆积坝、排污污水污染区、排风口降尘区、精矿转运区、外部农田区、离矿山10 km外背景值采集区共6区域46个点的土壤样品,对不同区域及外部农田区土壤中的Pb、Zn、As、Cd、Cu元素含量进行监测分析。结果表明:污染程度最严重的元素是Cd,其次是Pb;污染程度最严重的区域为排污污水污染区,其次是尾矿堆积坝,最轻的是排风口降尘区,外部农田受污染并不严重,Pb、Zn、As、Cd、Cu的污染程度基本处在轻-中污染程度以下,但有受到污染的潜在风险。
Soil samples were collected from 46 points in 6 areas,including mine tailings dam,sewage pollution area,exhaust outlet dust reduction area,concentrate transfer area,external farmland area and background value collection area 10 km away from the mine.The contents of Zn,Pb,Cd,Cu and As in the soils of different areas and external farmland areas were monitored and analyzed.The results show that the most pollution element is Cd,followed by Pb;the area with the most serious pollution degree is the sewage pollution area,followed by the mine tailings dam,and the lightest is the exhaust outlet dust reduction area.The external farmland is not seriously polluted.The pollution degree of Zn,Pb,Cd,Cu and As is basically below the light-medium pollution degree,but there is a potential risk of pollution.
