Overview of articles on POPs in a new issue of the Science of The Total Environment journal.

Circulating metals and persistent organic pollutant concentrations in Canadian and non-Canadian born primiparous women from five Canadian centres: Results of a pilot biomonitoring study

Pages 326-336
Warren G. Foster, Anthony P. Cheung, Karelyn Davis, Gillian Graves, John Jarrell, Alain Leblanc, Chun Lei Liang, Tara Leech, Mark Walker, Jean Philippe Weber, Jay Van Oostdam

  • Concentrations of metals and environmental contaminants were quantified in pregnant women from six Canadian Cities.
  • Significant differences between cities were documented.
  • Concentrations of several metals and contaminants were higher in foreign-born vs. Canadian women.

Organochlorine pesticides in seawater and the surrounding atmosphere of the marginal seas of China: Spatial distribution, sources and air–water exchange

Pages 244-252
Tian Lin, Jun Li, Yue Xu, Xiang Liu, Chunling Luo, Hairong Cheng, Yingjun Chen, Gan Zhang

  • OCPs were analyzed in air and water samples collected over marginal seas of China.
  • α-HCH concentrations in the atmosphere were quite uniform.
  • Atmosphericγ-HCH, TC, CC and DDT concentrations were highest in South China Sea.
  • Dissolved OCP concentrations in water varied over a narrow range.
  • Oceans exhibit net volatilization of some OCPs after a long period of prohibition.

Analytical approach and occurrence for the determination of mass concentration of PCDD/PCDF and dl-PCB in flue gas emissions using long-term sampling devices

Pages 7-13
J. Rivera-Austrui, K. Martínez, M.A. Adrados, M. Abalos, E. Abad

  • A method for the analysis of PCDD/Fs and dl-PCBs in samples from long-term sampling systems is presented.
  • Long-term sampling systems have proved to be suitable for the simultaneous sampling of PCDD/Fs and dl-PCBs.
  • A criteria for the aliquot size to be used in analysis is set-up depending on sampling time and thermal process.
  • The proposed methodology was tested on samples from incinerators and cement kilns.

Assessing PAH removal from clayey soil by means of electro-osmosis and electrodialysis

Pages 1-6
Ana T. Lima, Lisbeth M. Ottosen, Katja Heister, J.P. Gustav Loch

  • PAHs are persistent and ubiquitous contaminants with difficult removal from clays.
  • Electroremediation techniques (electro-osmosis and electrodialysis) may be a solution.
  • Electrodialysis is used here for the first time to study the removal of PAH from soil.
  • Removal efficiencies varied between 35 and 85%.
  • Results show high discrepancies in PAH removal on spiked and field contaminated soils.

Integrated hybrid treatment for the remediation of 2,3,7,8-tetrachlorodibenzo-p-dioxin   

Pages 563-566
Varima Bokare, Kumarasamy Murugesan, Jae-Hwan Kim, Eun-Ju Kim, Yoon-Seok Chang

  • Facile synthesis of bimetallic Pd/nFe nanoparticles was carried out in the laboratory.
  • 2,3,7,8-TeCDD was completely degraded at ambient conditions by Pd/nFe nanoparticles.
  • DD was the sole end product obtained after reduction of 2,3,7,8-TeCDD by Pd/nFe.
  • DD oxidation was achieved by sequential biodegradation usingSphingomonas wittichii.
