Distribution and Sources Apportionment of Polycyclic Aromatic Hydrocarbons in the Edible Bivalves and Sipunculida from Coastal Areas of Beibu Gulf, China
ثبت نشده
چکیده
Concentrations, composition and sources apportionment of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in the edible bivalves (oysters, mussels and clams) and sipunculida samples collected from coastal areas of Beibu Gulf, China. The results showed that the total PAH concentrations ranged from 36.4 to 403.3 ng/g dry weight. Compared with other bays and coastal areas, current contamination levels of PAHs were in a low range. Relative abundances and isomer ratios indicated a probable pyrogenic origin for the PAHs contamination. Further quantitative analysis showed that the percentages contributions of biomass and coal combustion, vehicular emission, coke oven emissions and crude oil pollution were 67.67%, 17.39% and 14.94%, respectively.

The upper layer of forest soils (0-20 cm depth) were collected from urban, suburban, and rural areas in the Pearl River Delta of Southern China to estimate the distribution and the possible sources of polycyclic aromatic hydrocarbons (PAHs). Total concentrations of PAHs in the forest soils decreased significantly along the urban-suburban-rural gradient, indicating the influence of anthropogenic...
