Abstract:

Polycyclic aromatic hydrocarbons (PAHs) were quantified in 15 topsoils from Taiyuan CityConcentrations of ∑PAHs in topsoils ranged from 098 to 2623 μg/g with an average of 865 μg/g, and the spatial distribution of ∑PAHs declined from north to southThe abundance of the heavier PAHs was more than that of the low molecular weight PAHsBy contrasting Taiyuan with other cities, the pollution of PAHs in Taiyuan City was extremely serious and the primary source of soil PAHs was the coal combustionThe industry distribution, the energy structure and the location of Taiyuan City were the reasons of heavily pollution of PAHs
