Polychlorinated dibenzo(p)dioxin and furan (PCDD/F) congener profiles in cement kiln emissions and impacts

Pages 37-43

  • Profiles of “dioxin” congeners emitted from two Portland cement kilns were examined. Congener profiles showed wide variability under nominally similar conditions. Use of waste-derived fuels had little effect on the congener profiles. The kilns' congener profiles were different from profiles measured in ambient air. The kilns' ambient impacts were found to be too small to be observable relative to background.

Bioaccumulation of polybrominated diphenyl ethers and decabromodiphenyl ethane in fish from a river system in a highly industrialized area, South China

Pages 109-115

  • Deca-BDE had gradually substituted by DBDPE in study area. wo debrominated products of DBDPE were the result of thermal degradation in instrumental analysis. Metabolism and diet were causes for the different PBDE congener profile among fish species. Significant bioaccumulation of DBDPE was occurring in fish species.

Temporal trends and spatial differences of perfluoroalkylated substances in livers of harbor porpoise (Phocoena phocoena) populations from Northern Europe, 1991–2008

Pages 216-224
Sandra Huber, Lutz Ahrens, Bård-Jørgen Bårdsen, Ursula Siebert, Jan Ove Bustnes, Gísli A. Víkingsson, Ralf Ebinghaus, Dorte Herzke
 

  • Statistically significant temporal trends for eight of ten detected PFASs. ► Higher concentration levels in the Baltic Sea than in the North Sea. ► Decreasing temporal trends for PFHxS, PFHpS, ΣPFOS and PFOSA. ► Increasing temporal trends for PFCAs. ► Spatial differences: Baltic Sea>Norwegian Atlantic Ocean>Icelandic Atlantic Ocean.

Modified Fenton oxidation of polycyclic aromatic hydrocarbon (PAH)-contaminated soils and the potential of bioremediation as post-treatment

Pages 240-249
Venny, Suyin Gan, Hoon Kiat Ng

  • Modified Fenton oxidation of PAHs in soil column experiments was optimised. Mild reagent concentration that is less costly was required at optimised condition. Natural attenuation as post-treatment promoted further PAH removal of up to 6.34%. Biostimulation as post-treatment promoted further PAH removal of up to 9.38%. Modified Fenton-bioremediation is a suitable strategy to enhance soil quality.
