Fate estimation of polycyclic aromatic hydrocarbons in soils in a rapid urbanization region, Shenzhen of China.

Our previous study indicated that the current level of polycyclic aromatic hydrocarbons (PAHs) in Shenzhen soil is in the low-end of world soil PAH pollution. In this study, the fate of PAHs in the soil of Shenzhen was investigated. The mass inventories of Σ(27)PAHs and Σ(15)PAHs (defined as the sum of the 27 or 15 PAH compounds sought) in topsoil of Shenzhen were ∼204 and ∼152 metric tons, respectively.

Occurrence and human non-dietary exposure of polycyclic aromatic hydrocarbons in soils from Shenzhen, China.

Twenty eight polycyclic aromatic hydrocarbons (PAHs) were determined for a total of 203 top soil samples collected from eight different land categories in Shenzhen, China during the winter of 2007. The concentrations, compositional profile, and the potential sources of PAHs in soil were discussed. Overall, PAH pollution in the soil of Shenzhen is still in the low-end of the world after 30 years rapid urbanization.

Occurrence, distribution, and source of polybrominated diphenyl ethers in soil and leaves from Shenzhen Special Economic Zone, China.

Polybrominated diphenyl ethers (PBDEs) were measured in soil and three plant species samples taken at different land use areas in Shenzhen China. The concentrations of Σ(7)BDEs (BDE-28, BDE-47, BDE-99, BDE-100, BDE-153, BDE-154, and BDE-183) and BDE-209 in the surface soils ranged from 0.23 to 271 and 8.
