摘要
1:20 万重庆幅区域化探显示Hg、Pb、Cr、Cd、Cu、Zn、Sb、Bi、F、P等元素在重庆市主城区异常发育,除Hg、Zn外重庆市均高于成都市,重庆市的污染更严重;Hg、Pb、Cr等元素在制药、造纸、化工、炼油和农药等工厂排污污染严重;河流污染长江、嘉陵江支流重于主流,主河流经过城区污染明显,长江污染重于嘉陵江,重庆市是长江的重要工业污染源;主要风景区和饮水源地球化学背景良好。区域化探在生态环境调查中取得了重要成果。
1 :2 000 000 regional geochemical mapping in Chongqing sheet indicates geochemical anomalies of Hg, Pb, Cr, Cd, Cu, Zn, Sb, Bi, F, P in Chongqing City proper. Chongqing City has been polluted by Hg, Pb, Cr from pesticide and in the waste water from pharmaceutical factories, paper mills, chemical plants, oil refineries. Rivers, especially, tributaries of the Yangtze River and the Jialing River, in the region have been seriously polluted. The Yangtze River and the Jialing River, especially the Yangtze River, in the city proper have been seriously polluted.
