| The main sources of heavy metal pollution in soil of agricultural producing area were analyzed in the paper, that were from industrial discharge, sewage irrigation, mineral resource development, agricultural inputs application, atmospheric particulates deposition, solid waste stacking, et al. Based on this, an inventory of industrial process source, fixed combustion source, source of irrigation water and solid waste stacking, mobile source and agricultural inputs source was built up. Related suggestions on heavy metal pollution supervision were proposed from two aspects: establishing and improving source prevention and strengthening process control. |
