Overview of new articles on POPs in a new issue of the Environmental Pollution journal.

Using disposable solid-phase microextraction (SPME) to determine the freely dissolved concentration of polybrominated diphenyl ethers (PBDEs) in sediments

Pages 34-40
Fang Jia, Xinyi Cui, Wei Wang, Laura Delgado-Moreno, Jay Gan

  • A disposable SPME method was developed for measuring Cfree of PBDEs in sediment.
  • Cfree decreased with increasing congener bromination or sediment OC content.
  • Cfree of PBDEs accounted for <0.012% of the total chemical mass in sediment.
  • High KDOC values suggest a high probability for DOM-facilitated offsite transport.

Polycyclic aromatic hydrocarbons in upstream riverine runoff of the Pearl River Delta, China: An assessment of regional input sources

Pages 78-84
Kai Zhang, Bo Liang, Ji-Zhong Wang, Yu-Feng Guan, Eddy Y. Zeng

  • Upstream PAH levels were lower than downstream PAHs and pose low ecological risk.
  • Riverine PAHs are predominantly pyrogenic.
  • Parent PAHs in Pearl River are mainly derived from within the PRD.
  • The 15 priority PAHs were mainly generated within the Pearl River Delta.

Polycyclic aromatic hydrocarbons (PAHs) in continental shelf sediment of China: Implications for anthropogenic influences on coastal marine environment

Pages 155-162
Liang-Ying Liu, Ji-Zhong Wang, Gao-Ling Wei, Yu-Feng Guan, Eddy Y. Zeng

  • Coal and biomass combustion was the main origin of PAHs in coastal marine sediment of China.
  • Fluvial transport was the main mode for transporting PAHs to the East China Sea inner shelf.
  • Atmospheric deposition largely accounted for sediment PAHs in Yellow Sea and the South China Sea.
  • Regional energy use pattern in China was responsible for the spatial distribution of PAHs in coastal marine sediment.
