Epidemiological and laboratory studies link polychlorinated biphenyls and their metabolites to adverse neurodevelopmental outcomes. Several neurotoxic PCB congeners are chiral and undergo enantiomeric enrichment in mammalian species, which may modulate PCB developmental neurotoxicity. This study measures levels and enantiomeric enrichment of PCB 95 and its hydroxylated metabolites (OH-PCBs) in ...
The current study evaluated certain emerging contaminants in the Susurluk sub-basin, which is under significant anthropogenic pollution pressure. Polychlorinated Biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), organochlorine insecticides, and microplastics were investigated from both surface sediment samples collected dry wet seasons. In Kocaçay river reaching Marmara Sea, γ-HCH β-HCH...
It is known that the consumption of seafood has several health benefits for humans. However, accumulation organic pollutants, such as polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs), in their flesh could pose public problems. Thus, concentrations PCBs OCPs edible fish species (Mugil bananensis, Sarotherodon melanotheron) from Sine Saloum Estuary located central-western Sen...
Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), are frequently detected in biota from Antarctica, whereas no data are available for their replacements, such as novel flame retardants (N-FRs). This study presented the occurrence of several N-FRs, PBDEs, and PCBs in tissue samples of an Antarctic rock cod (Trematomus ber...
This paper summarizes the health implications associated with exposure to polychlorinated biphenyls (PCBs), primarily through fish consumption. Recent studies complement and add to the scientific data gathered over the last two decades that document health consequences associated with exposures to PCBs. Although much of the research has been undertaken in the Great Lakes basin, the health impli...
BACKGROUND The present study assessed the temporal trend in serum concentrations of polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls (PCBs) among residents of a Russian town where levels of these chemicals are elevated due to prior industrial activity. METHODS Two serum samples were collected from eight adult women (in 2000 and 2009), and analyzed with gas chromatography-high-r...
The dynamics of persistent organic pollutants in the oceans are not well constrained, in particular during a bloom formation and collapse. Polychlorinated biphenyls (PCBs) and some pesticides were measured in air, water, and zooplankton tracking the North Atlantic Bloom in May 2008. Lower weight PCBs were entering the water column from the atmosphere during the main bloom period but reached equ...
