Abstract

According to the monitoring data of content of 8 main heavy metal elements in a certain urban area, this paper conducts a modeling study on heavy mental pollution of superficial soil in cities. According to single-factor concentration evaluation standard and comprehensive evaluation standard (Nemerow pollution index), pollution state of various areas has been worked out: industrial area > traffic area > living area > green area in the park > mountainous area. By considering variation coefficient of distribution of various heavy metal elements and correlation among them, deduce the main pollution source of different elements: As, Cr and Ni mainly come from coal combustion; Hg mainly comes from discard of lighting electrical appliances; Pb mainly comes from emission of automobile exhaust; Cu, Cd and Zn mainly come from industrial residue of factories. By combining with relevant correlation coefficient, deduction test model is given.
