This commentary presents a scientific basis for managing as one chemical class the thousands of chemicals known PFAS (per- and polyfluoroalkyl substances). The includes perfluoroalkyl acids, perfluoroalkylether their precursors; fluoropolymers perfluoropolyethers; other PFAS. approach is presented in relation to physicochemical, environmental, toxicological properties. Specifically, high persistence, accumulation potential, and/or hazards (known potential) studied date warrant treating all...
The spatial distribution of 29 per- and polyfluoroalkyl substances (PFASs) in seawater was investigated along a sampling transect from Europe to the Arctic two transects within Fram Strait, located between Greenland Svalbard, summer 2018. Hexafluoropropylene oxide-dimer acid (HFPO-DA), replacement compound for perfluorooctanoic (PFOA), detected first time. This provides evidence its long-range transport remote areas. total PFAS concentration significantly enriched cold, low-salinity surface...
Food contact materials (FCMs) are intended to be in with food during production, handling or storage. They one possible source of contamination, because chemicals may migrate from the material into food. More than 6000 FCM substances appear on regulatory non-regulatory lists. Some these have been linked chronic diseases, whilst many others lack (sufficient) toxicological evaluation. The aim this study was identification known that also considered concern (COCs). investigation based following...
Abstract The Arctic Ocean is known to be contaminated by various persistent organic pollutants (POPs). Fram Strait, the only deepwater passage (from Atlantic Ocean), represents an unquantified gateway for POPs fluxes into and out of Arctic. Polyethylene passive samplers were deployed in vertical profiles Strait air surface water Canadian Archipelago determine concentrations, profiles, mass dissolved polychlorinated biphenyls (PCBs) organochlorine pesticides. In higher concentrations ΣPCBs...
Abstract Human activities have released large quantities of neutral persistent organic pollutants (POPs) that may be biomagnified in food webs and pose health risks to wildlife, particularly top predators. Here we develop a global 3‐D ocean simulation for four polychlorinated biphenyls (PCBs) spanning range molecular weights volatilities better understand effects climate‐driven changes biogeochemistry on the lifetime distribution POPs. Observations are most abundant Arctic Ocean. There,...
Small-scale fisheries (SSFs) are essential for global food security, especially in low- and lower-middle-income countries (LLMIs), where they a primary source of protein micronutrients millions people. SSFs contribute half fishery catch globally, but least developed over 80% originates from SSFs, making them critical regions other sources scarce or unaffordable. However, ocean pollution—from chemicals, plastics, contaminants—poses an increasingly urgent threat to these the health communities...
Oceans have remained the least well-researched reservoirs of persistent organic pollutants (POPs) globally, due to their vast scale, difficulty access, and challenging (trace) analysis. Little data on POPs exists along South America effect different currents river plumes aqueous concentrations. Research cruise KN210-04 (R/V Knorr) offered a unique opportunity determine POP gradients in air, water, air-water exchange America, covering both hemispheres. Compounds interest included...
