五大连池大气中PAHs污染源解析及控制措施

Pollution Source Apportionment And Control Measure Of Pahs In Air In Wudalianchi

对于五大连池大气中PAHs的污染研究,通过在该地区的农村设置大气采样点,进行了为期一个季度的大气样品采集,对PAHs的污染来源进行了初探,运用比值法和主成分分析法相结合对大气中PAHs的来源进行了定性和定量研究,结果表明,煤和生物质等的高温燃烧源是五大连池大气中PAHs的主要污染源,贡献率为83.5%,地表挥发和大气传输源的混合源的贡献率为16.5%。

For the pollution study of PAHs in Wudalianchi, the air samples were collected in a typical rural area for one season. The pollution sources of PAHs were investigated. The selected diagnostic ratios and PCA were combined for the source apportionment of PAHs in air in Wudalianchi. The pyrogenic combustion sources of coal and biomass was the primary source of PAHs in the air in Wudalianchi, accounting for 83.5% of ∑ 16PAHs, followed by the mixed source of surface evaporation and atmospheric transportation （ 16.5% ） .
