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.
