BACKGROUND In animal experiments persistent organic pollutants (POPs) cause hepatosteatosis. In epidemiological studies POPs have positive associations with serum markers of nonalcoholic fatty liver disease (NAFLD) and together with obesity synergistic association with insulin resistance. Because insulin resistance and obesity are critical in NAFLD pathogenesis, we investigated the association ...

Several recent studies have shown that n-octanol/water partition coefficients may not be a good predictor for estimating soil sorption coefficients of persistent organic pollutants (POPs), defined here as chemicals with log Kow greater than 5. Thus, an alternative QSAR model was developed that seems to provide reliable estimates for the soil sorption coefficients of persistent organic pollutant...

Human exposure to environmental chemicals as persistent organic pollutants (POPs) is usually assessed considering each pollutant individually, with little attention to concentrations of mixtures in individuals or social groups. Yet, it may be relatively common for humans to have low and high concentrations of numerous POPs. The study objectives were to analyze the number of POPs detected per pe...

Among them, perfluorooctane sulfonate (PFOS) is speculated to be highly persistent, bioaccumulative and toxic (PBT) compound. Afterwards, PFOS and its synthetic starting material, perfluorooctyl sulfonyl fluoride (PFOSF), have been designated as persistent organic pollutants (POPs) by the Stockholm Convention on POPs in 2009. Therefore, to efficiently reduce PFC pollution, an understanding of P...

This article discusses the topics and ideas presented at the Special Session of the conference Dioxin 2008 (28th International Symposium on Halogenated Environmental Organic Pollutants and POPs) titled: "Emerging POPs". The session was devoted to emerging and re-emerging compounds or groups of compounds identified recently as environmental contaminants and classified as dioxin-like compounds or...

Fish is a highly nutritious food, but it can also be a dietary source of persistent organic pollutants (POPs). In a new study in EHP, researchers investigated the extent to which contaminant levels within a single commercially important fish species varied depending on where the fish was caught. Their results suggest that capture location may be an important yet overlooked variable when assessi...

Research over the last decade indicates that adipose (fat) tissue serves as more than an energy depot. The tissue has a dynamic role in maintaining normal carbohydrate and lipid levels as well as in regulating metabolic and other physiologic functions. Persistent organic pollutants (POPs), including certain organochlorine pesticides and numerous industrial chemicals, are highly attracted to lip...

This review is a follow-up to previous published in Journal of Marine Science and Engineeringon the issues accumulation, transport, effects microplastics (MPs) oceans. The brings together experimental laboratory, mathematical, field data on dual role MPs as accumulators hydrophobic persistent organic compounds (POPs), their release-effect marine ecosystem. It also examines carrier role, besides...
