农产品产地土壤重金属外源污染来源解析及防控策略研究

摘要

分析了工业生产排放、污水灌溉、矿产资源开发、农业投入品施用、大气颗粒物降尘及固体废弃物堆放等农产品产地土壤重金属主要外源污染来源,在此基础上构建了包括工业过程源、固定燃烧源、灌溉水源、废弃物堆放源、流动源和农业投入品源的来源清单,并从建立健全源头预防和强化过程控制2个方面,提出了加强农产品产地土壤重金属污染监管的相关建议.%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.
