Abstract (English):: Understanding the distribution characteristics, pollution level, and source is important to prevent pollution and utilize the farmlands around industrialized areas. In this study, we collected 89 soil samples from farmlands around oil mining area in Yellow River Delta and 148 samples from farmlands around southwestern lead-zinc smelting area. The composition and contents of 16 polycyclic aromatic hydrocarbons (PAHs) precedence-controlled by the EPA were analyzed by gas chromatography-mass spectrometery. The sources of PAHs in these two areas were modelled with the principal component analysis and positive matrix factorization. The results showed that the average ΣPAH content was 149.8 μg·kg-1 in farmlands around oil mining area and 267.6 μg·kg-1 in farmlands around southwestern lead-zinc smelting area, dominated by 4~6-ring PAHs.The sources of PAHs included gasoline combustion (24.1%), diesel combustion (6.2%), biomass combustion and oil source (60.7%), and coal combustion (9.1%) in farmlands around oil mining area, and biomass combustion and oil source (31.6%), diesel combustion (28.3%), and coal combustion (40.1%) in southwestern lead-zinc smelting area. The sources of PAHs were related to the energy consumption in the local area. [ABSTRACT FROM AUTHOR]
