Removal of α- and γ-hexachlorocyclohexane and enantiomers of α-hexachlorocyclohexane in the eastern Arctic Ocean
Atmospheric concentrations of hexachlorocyclohexanes (HCHs) have declined over the last two decades, and the Arctic Ocean is now eliminating HCHs through degradation, volatilization, and advectiveExpand
Polycyclic Aromatic Hydrocarbons (PAHs) in Soil and Sediment from Industrial, Residential, and Agricultural Areas in Central South Africa: An Initial Assessment
Polycyclic aromatic hydrocarbons (PAHs) are of global concern due to their ubiquitous presence, toxicity, and carcinogenicity. No data on PAHs in soils from South Africa have been published, evenExpand
Perfluoroalkyl acids in the Atlantic and Canadian Arctic Oceans.
Data from previously unstudied coastal waters of North and South America, and the Canadian Arctic Archipelago help validate global emissions models and contribute to understanding of long-range transport pathways and sources of PFAAs to remote regions. Expand
Dioxin-like chemicals in soil and sediment from residential and industrial areas in central South Africa.
High resolution gas chromatography-high resolution mass spectrometry and the H4IIE-luc bio-assay were used to identify and quantify individual PCDD/F congeners and to report the total concentration of 2,3,7,8-tetrachloro dibenzo-p-dioxin equivalents (TCDD-EQ), respectively. Expand
Polychlorinated Naphthalenes and Coplanar Polychlorinated Biphenyls in Arctic Air
Concentrations of polychlorinated naphthalenes (PCNs) are reported for the first time in arctic air. The data represent combined air samples from the Barents Sea (n = 2), eastern Arctic Ocean (n =Expand
Comparing Water, Bovine Milk, and Indoor Residual Spraying as Possible Sources of DDTand Pyrethroid Residues in Breast Milk
It is postulated that a better understanding of the indoor dynamics of DDT and other insecticides, through a concept of Total Homestead Environment Approach (THEA), is crucial for investigating options of reducing human exposure and uptake under malaria control conditions. Expand
High levels of DDT in breast milk: intake, risk, lactation duration, and involvement of gender.
There were indications from DDT-sprayed villages that first- born female infants drink milk with more ΣDDT than first-born male infants, and vice versa for multipara male and female infants, suggesting gender involvement on levels of DDT in breast milk - requiring further investigation. Expand
Environmental monitoring of polychlorinated biphenyls using pine needles as passive samplers.
Pine needles were used as passive samplers for monitoring polychlorinated biphenyls (PCBs) in the environment and a method for the determination of PCB in pine needle was developed, achieving high precision and accuracy. Expand
Anaerobic Degradation of Nonylphenol Mono- and Diethoxylates in Digestor Sludge, Landfilled Municipal Solid Waste, and Landfilled Sludge
The aim of this study was to investigate the extent to which anaerobic digestor sludge, landfilled sludge, and landfilled municipal solid waste (MSW) degrade NPEOs [nonylphenol ethoxylates] underExpand
