江西省PM2.5污染现状及来源解析进展

Current Situation and Source Analysis of PM2.5 in Jiangxi Province

PM2.5是指空气中空气动力学单量小于或等于2.5微米的颗粒物,PM2.5粒径小,活性大,含有大量有毒有害物质,并且能够长时间的悬浮在空气中,因此,PM2.5在空气含量中浓度越高,空气污染越严重,空气质量越差。江西省随着经济的发展,工业污染排放增多,人口和车辆增多,环境污染越来越严重,现就江西省PM2.5污染现状进行概述,分析PM2.5的来源及采取的解决措施,并对措施实施效果进行简单评估。通过分析,进一步展望江西省PM2.5未来发展趋势、来源的可能性变化及合理的配套措施。

PM2. 5 refers to the micron particles of single volume is less than or equal to 2. 5 in the air dynamics , PM2.5 particle size is small, active, contains large amounts of toxic and harmful substances, and can suspended for a long timein the air. Therefore, the higher concentration of PM2. 5 in air, the more serious air pollution, air quality worse. With the development of economy, the industrial pollution emissions, population and vehicles in- creasing, environmental pollution is becoming more and more seriousin Jiangxi Province. PM2. 5 pollution status are summarized here, and this paper analysis the PM2.5 source and take measurements to solve the problems, simple assessment of the effect of measures for implementation was performed as well. Through the analysis, the future development trend of PM2.5 in Jiangxi Province, the source of the possibility of change and the reasonable supporting measures were predicted.
