摘要
常绿植物作为大气污染的指示物,为了解郑州市常绿植物对大气污染物多环芳烃的指示作用,以郑州市部分地区为样地,运用气相-质谱联用仪测定了健康生长的常绿植物冬季叶片中的多环芳烃的含量,并对其进行了源解析。结果显示:北美香柏叶片中多环芳烃的总含量最高,其中北美香柏叶片中PAHs干重含量为3209.39 ng/g、女贞PAHs含量为1821.09 ng/g、石楠PAHs含量为1161.79 ng/g。源解析结果显示植物叶片中的PAHs主要来源于煤炭、生物质的燃烧。
In order to understand the indication of polycyclic aromatic hydrocarbons(PAHs)by evergreen plants in Zhengzhou,the content of PAHs in the leaves of evergreen plants in Zhengzhou was determined and analyzed.The results showed that the contents of PAHs in Thuja occidentalis,Ligustrum lucidum,Photinia and leaves were 3209.39 ng/g,1821.09 ng/g and 1161.79 ng/g,respectively.The results of source apportionment showed that PAHs in plant leaves mainly came from the combustion of coal and biomass.
