摘要: We studied the profiles, possible sources, and transport of polycyclic aromatic hydrocarbons (PAHs) in soils from Longtang area, which is an electronic waste (e-waste) recycling center south China. The sum 16 PAH concentrations ranged 25 to 4,300 ng/g (dry weight basis) following order: pond sediment sites (77 ng/g), vegetable fields (129 paddy (180 wastelands (258 dismantling (678 former open burning (2,340 ng/g). Naphthalene, phenanthrene, fluoranthene, pyrene, chrysene, benzo[b]fluoranthene were dominant PAHs accounted for approximately 75 % total PAHs. similar composition characteristics significant correlations among individual, low molecular weight, high found all six sampling site types, thus indicating that originated sources. results both isomeric ratios principal component analyses confirmed mainly derived incomplete combustion e-waste. main sources Soil samples taken closer point had concentrations. are transported via different soil including those agricultural fields, have been detected not only 0- 40-cm-deep but also 40 cm 80 cm-deep soil. strongly affected by primitive e-waste recycling, particularly activities.
