Abstract:It’s necessary precondition to know about spatial and industrial distribution pattern of heavy metals emission in industrial waste water that carry out national prevention and control. The spatial analysis based on GIS showed that Hg、Cd、Pb、As emissions are mainly concentrated in 4 southern provinces including Hunan, Jiangxi, Guangxi and Yunnan, and 2 northern provinces, Gansu and Shaanxi; Cr6+ concentrated in 4 eastern coastal provinces including Guangdong, Fujian, Zhejiang, Jiangsu. The pollutions in southern and northern provinces were closed connected with local resources dependent industries such as mining, smelting and processing ferrous or non-ferrous metal ores; the pollutions in eastern coastal a provinces are related with the manufacture industries such as metal products, transport or electrical machinery, communication equipment, chemical products etc. There are huge differences on heavy metals discharge characteristics and emission reduction rate among provinces and industries, which reflects that national prevention and control of heavy metal pollution dependent upon multidisciplinary research support.
