<\/a> Bound and Unbound: Seeking to Understand PFAS in the Bloodstream<\/a> -<\/span> PFAS binds to blood serum proteins and impacts protein accumulation, circulatory distribution, and elimination. The unbound portion of PFAS, untouchable by biomolecules, can be transported to organs and recirculated in the bloodstream, and therefore more likely to elicit toxic effects. In a recent study, STEEP researchers investigated the competitive binding of PFAS to two major… ...Read more<\/a><\/span><\/li>![\"\"](\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/Arctic-176x133.jpeg\")
<\/a> STEEP Researchers Track PFAS, Circulating, Cycling Worldwide<\/a> -<\/span> Evidence suggests PFAS in the remote northern hemisphere are the result of long-range transport in the air and ocean. STEEP researchers deployed passive samplers in the Fram Strait, a passage of water between Greenland and the Norwegian archipelago of Svalbard, with aims to understand PFAS there and assess if sources of PFAS are changing.

<\/a> Combined with High-Fat Diet, PFOS Exposure Impacts Neurodevelopment in Mice<\/a> -<\/span> PFOS can affect several brain functions including memory, coordination, and social activity. Similarly, diets high in fat can impair cognition and increase risk for dementia. A study from STEEP researchers explores the relationship between PFOS exposure and a high-fat diet, demonstrating that the combination promotes repetitive behavior, hyperactivity and social withdrawal in mice. ...Read more<\/a><\/span><\/li>![\"\"](\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/MOBILE-200x93.jpg\")
<\/a> Mobile-Laboratory Experiments Assess PFAS in Fish, Mussels on Cape Cod<\/a> -<\/span> Aqueous film-forming foams (AFFF) were historically deployed for fire department training activities on Joint Base, Cape Cod, Massachusetts, and resulted in extensive groundwater PFAS contamination. In this study from STEEP researchers, PFAS concentrations in aquatic species, water, and samplers, a result of groundwater discharging to surface waters, were evaluated in mobile-laboratory experiments. ...Read more<\/a><\/span><\/li>![\"\"](\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/eel-200x105.jpeg\")
<\/a> PFAS in Groundwater and Eel Emphasize Need for Standards<\/a> -<\/span> STEEP researchers collaborated with seven independent, international laboratories, representing academic, government, and commercial organizations, to compare extractable organoflourine and targeted PFAS measurements in groundwater and eel (Anguilla rostrata) from sites contaminated with fire-fighting foam. Overall, the comparison underscores the need for standard methods for sample extraction, instrumental analysis, and data processing. ...Read more<\/a><\/span><\/li>![\"\"](\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/Pawcatuck_river-200x133.jpg\")
<\/a> STEEP Researchers Find Small RI River May Pose a Big PFAS Problem<\/a> -<\/span> In research, textiles and PFAS have long been intertwined. Yet the public understanding of this connection is less obvious, even more so considering that river-side textile mills have existed far longer than our knowledge of PFAS. A recent study by STEEP researchers suggests that both active and shuttered textile mills along a small river in… ...Read more<\/a><\/span><\/li>![\"\"](\"https:\/\/web.uri.edu\/steep\/wp-content\/uploads\/sites\/1022\/rainer-1-108x133.jpg\")
