Freshwater fishUrban lakesConcentrations and profiles of 17 perfluoroalkyl substances (PFAS) including 13 perfluorocarboxylic acids (PFA) and 4 perfluoroalkyl sulfonates (PFS) were determined in whole blood, muscle, and liver samples of four freshwater fish species in West Lake and Yen So Lake (...
"Most existing research focuses on PFAS levels in freshwater species, which are not what people primarily eat," said Romano, who studies the effects of PFAS and other endocrine-disrupting chemicals in drinking water on New England communities. "We saw that as a knowledge gap in the literature,...
In addition, analyses of blood serum samples provided the internal concentration of 14 PFAS. The survey design allowed to extrapolate the data obtained on the 478 individuals to the freshwater angler population. Descriptive data regarding internal levels of PFAS were discussed at the population level,...
freshwater fishbiota monitoringFish concentrations of perfluorocarboxylic and perfluorosulfonic acids were reported for seven deep lakes in the European subalpine area, namely Lake Geneva, L. Lugano and L. Maggiore, L. Iseo, L. Como, L. Garda and L. Mergozzo, one shallow lowland (L. Varese) ...
William Dichtel, Ph.D., a professor of chemistry at Northwestern University, tells TODAY.com that many food supplies have also been contaminated, as many freshwater fish live in water with PFAS, animals eat PFAS-contaminated grasses, and produce grow in or are irrigated with PFAS-contaminated ...
Freshwater fish typically have higher PFOS concentrations than marine systems, which may influence these findings [170]. Because cross-sectional studies might be subject to reverse causation [171], longitudinal studies are preferable when evaluating predictive relationships between environmental chemicals and...
anguilla), and in translocated freshwater mussels (Dreissena bugensisandCorbicula fluminea)at 44 sampling locations within the main water basins of Flanders, the northern part of Belgium. Finally, both human health risk and ecological risk were assessed based on accumulated concentrations in fish muscle...
epidemiology at Dartmouth College’sGeisel School of Medicinein New Hampshire, highlighted that most research had previously focused on PFAS levels in freshwater species, “which are not what people primarily eat. We saw that as a knowledge gap in the literature, especially for a New England ...
Here we show the maternal offloading of PFAS in freshwater short-necked turtles (Emydura macquarii macquarii) exposed to elevated PFAS and the resulting biological impact on oviducal eggs. Total PFAS concentrations were determined in serum from adult females and harvested oviducal eggs collected ...
Freshwater is a Diminishing Resource We will need to invest in tools, systems and innovation to better combat, manage and track water risk.As the planet warms and emissions continue to disrupt the climate, the first impacts we see will be water related. Whether that be flooding, drought, sea...
