| Popis: | The heavy metal pollution made by industrial coal in city is receiving more and more attentions, but the time effect researches on fire coal capacity and heavy metal pollution after enterprise' relocation out of urban area are comparatively less. This paper studied the east Industrial zone, doing quantitative analysis on 5 types of heavy metal elements of coal samples, cinder, coal ash, topsoil, deep soil by x fluorescence analysis in 2004, 2006, 2009, discussing the time effect of urban air dust and soil heavy metal pollution during the process of reduced fire coal. The results show that: (1) urban industrial fire coal had spatial effect to heavy metal pollution, with a usual order such as floating dust > top soil> deep soil. (2) The reduction of fire coal would decline the contents of heavy metal in floating dust soon, but the soil especially the deep soil was still polluted by fire coal during a lasting time. (3) The shutting down of thermal power plant would make a positive effect on the recovery of air quality, however demolishing would cause more serious pollution without a series of environmental protection measures in the short period of time. |
