Abstract: | Studies of polycyclic aromatic hydrocarbons (PAHs) in the surface soil were conducted in Huizhou City, which is located in
the Pearl River Delta, South China. Sixteen PAHs in 42 soil samples were detected. The results showed that 4 components of
PAHs were detectable in all soil samples, and other 12 components were also detectable to some extent. The total PAHs contents
range from 35.40 to 534.5 μg/kg with the mean value of 123.09 μg/kg. Soil in Huizhou was slightly polluted by PAHs according
to Maliszewska-Kordybach’s study. It can be confirmed that the increase of PAHs contents in the surface soil of Huizhou City
is closely connected to human activities. Multivariate analysis was also made in this study. Principal component analysis
was used to constrain their origins, and 3 principal components (PCs) were extracted. The results showed that coal combustion
and oil spilling made the major contributions to PAHs. Cluster analysis was made and 16 priority PAHs were classified as 4
sorts, and the result revealed the differences in environmental behavior, chemical properties and sources of PAHs. |
