Atmospheric Concentrations of Polycyclic Aromatic Hydrocarbons in the Watershed of Lake Victoria, East Africa

Kenneth Arinaitwe, Bernard T. Kiremire, Derek C.G. Muir, Phil Fellin, Henrik Li, Camilla Teixeira, and Drake N. Mubiru
pp 11524–11531

  • In the first study of its kind in Africa, PAHs were measured in high volume (24 h) air samples collected from two sampling stations, at Kakira and Entebbe (KAK and EBB, respectively) within the Lake Victoria watershed in Uganda, to assess source contributions and generate a baseline reference data set for future studies in the East African region.

Mechanisms and Implications of α-HCH Enrichment in Melt Pond Water on Arctic Sea Ice

M. Pućko, G. A. Stern, D. G. Barber, R. W. Macdonald, K.-A. Warner, and C. Fuchs
pp 11862–11869

  • During the summer of 2009, we sampled 14 partially refrozen melt ponds and the top 1 m of old ice in the pond vicinity for α-hexachlorocyclohexane (α-HCH) concentrations and enantiomer fractions (EFs) in the Beaufort Sea.

Passive Sampling to Measure Baseline Dissolved Persistent Organic Pollutant Concentrations in the Water Column of the Palos Verdes Shelf Superfund Site

Loretta A. Fernandez, Wenjian Lao, Keith A. Maruya, Carmen White, and Robert M. Burgess
pp 11937–11947

  • Passive sampling was used to deduce water concentrations of persistent organic pollutants (POPs) in the vicinity of a marine Superfund site on the Palos Verdes Shelf, California, USA. Precalibrated solid phase microextraction (SPME) fibers and polyethylene (PE) strips that were preloaded with performance reference compounds (PRCs) were codeployed for 32 d along an 11-station gradient at bottom, surface, and midwater depths.

Atmospheric Short-Chain Chlorinated Paraffins in China, Japan, and South Korea

Qilu Li, Jun Li, Yan Wang, Yue Xu, Xiaohui Pan, Gan Zhang, Chunling Luo, Yuso Kobara, Jae-Jak Nam, and Kevin C. Jones
pp 11948–11954

  • This study presents the first investigation of concentrations and congener group patterns of atmospheric short-chain chlorinated paraffins (SCCPs) throughout East Asia. Based on an absorption rate calibration experiment, a spatial survey of SCCPs was performed using passive air samplers in China, Japan, and South Korea during two separate periods in 2008.

Large-Scale Field Study on Thin-Layer Capping of Marine PCDD/F-Contaminated Sediments in Grenlandfjords, Norway: Physicochemical Effects

Gerard Cornelissen, Katja Amstaetter, Audun Hauge, Morten Schaanning, Bjørnar Beylich, Jonas S. Gunnarsson, Gijs D. Breedveld, Amy M.P. Oen, and Espen Eek
pp 12030–12037

  • A large-scale field experiment on in situ thin-layer capping was carried out in the polychlorinated dibenzodioxin and dibenzofuran (PCDD/F) contaminated Grenlandsfjords, Norway.

Enhanced Solubilization and Desorption of Organochlorine Pesticides (OCPs) from Soil by Oil-Swollen Micelles Formed with a Nonionic Surfactant

Guanyu Zheng, Ammaiyappan Selvam, and Jonathan W. C. Wong
pp 12062–12068

  • The effect of oil-swollen micelles formed with nonionic surfactant polyoxyethylene sorbitan monooleate (Tween 80), cosurfactant 1-pentanol, and linseed oil on the solubilization and desorption of organochlorine pesticides (OCPs) including DDT and γ-HCH from both loam soil and clay soil were investigated.

Predictors of Tetrabromobisphenol-A (TBBP-A) and Hexabromocyclododecanes (HBCD) in Milk from Boston Mothers

Courtney C. Carignan, Mohamed Abou-Elwafa Abdallah, Nerissa Wu, Wendy Heiger-Bernays, Michael D. McClean, Stuart Harrad, and Thomas F. Webster
pp 12146–12153

  • Tetrabromobisphenol-A (TBBP-A) and hexabromocyclododecanes (HBCDs) are brominated flame retardants that have been found in human milk and serum throughout the world, but have received comparatively little attention in the United States. The objective of this study is to determine concentrations of these analytes in samples of breast milk collected from first-time mothers in the Greater Boston, Massachusetts area and to explore predictors of exposure.

Global Liver Proteome Analysis Using iTRAQ Labeling Quantitative Proteomic Technology to Reveal Biomarkers in Mice Exposed to Perfluorooctane Sulfonate (PFOS)

Feng Tan, Yihe Jin, Wei Liu, Xie Quan, Jingwen Chen, and Zhen Liang
pp 12170–12177

  • Proteomic analysis allows detection of changes of proteins expression in organisms exposed to environmental pollutants, leading to the discovery of biomarkers of exposure and understanding of the action mechanism of toxicity. In the present study, we applied iTRAQ labeling quantitative proteomic technology for global characterization of the liver proteome in mice exposed to perfluorooctane sulfonate (PFOS).

Formation and Emission of PCDD/Fs in Chinese Non-Wood Pulp and Paper Mills

Xueli Wang, Yuwen Ni, Haijun Zhang, Xueping Zhang, and Jiping Chen
pp 12234–12240

  • Chlorine bleaching is still practiced by non-wood pulp and paper mills in China, resulting in considerable formation and emission of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). We investigate the distribution of PCDD/Fs in different papermaking processes and dioxin emissions at six typical Chinese non-wood pulp and paper mills.
