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

Size distribution of EC, OC and particle-phase PAHs emissions from a diesel engine fueled with three fuels

Pages 33-41
Tian Lu, Zhen Huang, C.S. Cheung, Jing Ma

  • Size-resolved diesel particles were collected and analyzed for EC, OC and PAHs.
  • The reduction effect of biodiesel concentrated on EC emission in large size range.
  • Biodiesel could reduce PAHs emission, especial for heavy PAHs in small size range.
  • Biodiesel could reduce the carcinogenic potency of PAHs in all the size ranges.

Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and non-ortho-PCBs in eggs of white-tailed sea eagles collected along the Swedish coast in the Baltic Sea

Pages 166-173
Ulrika Nordlöf, Björn Helander, Yngve Zebühr, Anders Bignert, Lillemor Asplund

  • PCDD/Fs levels in white-tailed sea eagle (WTSE) eggs from the Baltic Sea and Greenland.
  • 2,3,4,7,8-PCDF was the predominant congener in all areas.
  • The total toxic equivalents (TEQ) in the WTSE were higher than reported in eggs for many other birds.
  • The major contributors to the TEQ in the Baltic Sea were the non-ortho-PCBs.

East versus West: Organic contaminant differences in brown pelican (Pelecanus occidentalis) eggs from South Carolina, USA and the Gulf of California, Mexico

Pages 527-532
Stacy S. Vander Pol, Daniel W. Anderson, Patrick G.R. Jodice, Joyce E. Stuckey

  • This was the first known analysis of BDEs in the Gulf of California (GofCA).
  • Brown pelicans in southeast U.S. (SC) and GofCA have different population trends.
  • GofCA eggs had higher levels of lower brominated BDEs than SC; patterns also varied.
  • PCBs, chlordanes, dieldrin and mirex were greater in SC eggs; DDTs and HCHs were lower.
