【摘要】 为了了解北京市园林树种对大气污染物多环芳烃的富集特征,以陶然亭公园、东灵山风景区以及马甸公园为样地,运用液相色谱法测定了6种健康生长的树种夏季叶片中多环芳烃的含量,并对3个样地的相同树种进行不同样地叶片多环芳烃来源进行研究。结果显示:同一样地叶片多环芳烃含量存在种间差异。陶然亭公园6种植物叶片中,油松叶片中的多环芳烃总含量最高,按照叶片多环芳烃总含量多少来排序,6种植物叶片的排序为:油松>太平花>暴马丁香>白杆>元宝枫>山杏。以油松叶片为研究对象,对比油松叶片在陶然亭公园、马甸公园以及东灵山风景区的叶片PAHs来源,发现石油源是3个样地中叶片内多环芳烃含量的主要来源。更多还原

【Abstract】 To understand the absorption features of garden tree species for PAHs as a kind of air pollutant,6 kinds of garden trees at Tao Ran Ting park in summer were tested by high-performance liquid chromatography(HPLC),and one of the 6 kinds of healthy trees from different area were tested to understand the sources of PAHs in leaves.The results show that:The absorption characteristics for PAHs from 6 tested trees in the same sampling plot have species between species.The leaves of Pinus tabulaeformis have the highest total content of PAHs,and the order according to the content of PAHs in leaves from high to low is:Pinus tabulaeformis > Philadelphus pekinensis > Sryringa reticulata var.amurensis > Picea meyeri > Acer truncatum> Armeniaca sibirica at Taoranting Park.The sources of PAHs in the leaves of Pinus tabulaeformis in Taoranting park,Madian park and Dongling mountain Scenic Area were studied and the results show that the activities related to petroleum maybe the main sources of PAHs.更多还原
