The content of heavy metals(Pb, Cr, Cd, Hg, As, Cu, Zn, Ni) was analyzed by ICP-OES. Adopting the Background value and standard deviation law method, single contamination index method, the Nemerow comprehensive contamination index method, the pollution were calculated to assess the pollution extent.
