OCCURRENCE AND DISTRIBUTION OF POLYCYCLIC AROMATIC HYDROCARBONS IN SOILS FROM AN E-WASTE RECYCLING AREA IN SOUTHEAST CHINA
Surface soils collected from Taizhou, a typical e-waste recycling area in Southeast China, were analyzed for the residues of polycyclic aromatic hydrocarbons (PAHs) by using microwave-assisted extraction (MAE) and gas chromatography-mass spectrometry (GC-MS). The total concentrations of PAHs (ΣPAHs) in soils ranged from 124.75 to 4737.15 ng/g with an average of 854.33 ng/g. The levels of PAHs found here were comparable with those of serious polluted sites, which implied that the soils in Taizhou area have been heavily polluted by PAHs. Analysis of the composition patterns of PAHs indicated no obvious differences in different sampling sites. Principal component analysis (PCA) in combination with diagnostic ratios suggested that the combustion of coal, wood, and plastic wastes that are closely associated with illegal and unsafe recycling operations of e-wastes be the main source of PAHs in this area.
