摘要
测定了新乡市不同功能区的20个室外尘土样品中16个中美国环保局优先控制的多环芳烃(PAHs)。结果显示室外尘土中PAHs总和(ΣPAHs)为124～1 669μg/kg(干重)。虽然广场类型的室外尘土样品中ΣPAHs含量均值小于生活区和工业区类型的,但3组样品的数值之间并无明显差异。同分异构体比率显示样品中PAHs以燃烧来源为主,主成份分析显示多数样品相对聚集,表现出大气传输对室外尘土样品的影响。
The concentration and composition of 16 polycyclic aromatic hydrocarbons （PAHs） on the US EPA prio pollutant list in 20 outdoor dust samples were determined. The results showed that the concentration of EPAHs in dust samples from three different function area of Xinxiang City were between 124 and 1 669 p,g/kg（dw）. Although ~PAHs in the park area dust were lower than both in the difference among these dust samples collected form the indicated that the primary PAHs source in outdoor dus analysis showed that most samples were assembled, which living area and the industrial park, there was no significant three function areas respectively. The PAH isomer ratios t samples were combustible. And the principal component indicated the effect of the atmosphere transport on the outdoor
