STEEP researcher contributes to study confirming link between PFAS \u2013 \u2018forever chemicals\u2019 \u2014 in drinking water and weight gain<\/strong><\/p>\n

A University of Rhode Island researcher leads a study that confirms a direct link between certain chemicals in drinking water and human obesity \u2013 specifically that increased PFAS content in blood promotes weight gain and makes it harder to keep a lower body weight after weight loss. Philippe Grandjean, M.D., PhD., is physician who holds a research professor appointment within the URI College of Pharmacy and serves on STEEP, a special URI-led science effort helping the public grapple with manmade PFAS (per-and polyfluoroalkyl substances) pollution, including its presence in drinking water resources.<\/p>\n

\u201cWe\u2019ve previously shown that children with increased PFAS concentrations tend to gain weight and develop higher levels of cholesterol in the blood,\u201d said Grandjean, a professor of environmental medicine at the University of Southern Denmark, who has researched the human health impacts of PFAS in multiple countries and populations, including children, for decades. \u201cWe now focused on adults who participated in an experimental study of five different diets in regard to weight gain. Our results add to the concern that environmental pollution may be affecting our metabolism, so that we tend to gain weight.\u201d<\/p>\n

For the recent study, the researchers, using STEEP-affiliated laboratories, analyzed PFAS chemicals in 381 blood samples that were already part of a randomized European Commission clinical trial in Europe focused on weight loss planning for obese adults. No matter the diet that these participants were assigned to, they gained weight if they had elevated PFAS exposures. One particular chemical, PFOA, which is commonly found in contaminated drinking water, demonstrated, more so than other PFAS pollutants, ties to obesity. Furthermore, those participants in the European study with the most PFOA in their blood were found, after a one-year follow-up, to have gained about 10 pounds more than those with low levels.<\/p>\n

\u201cOur study adds new evidence that being overweight isn\u2019t just about a lack of physical activity and unhealthy eating habits \u2013 PFAS are increasingly suspected to be a contributing factor,\u201d said Grandjean. \u201cThe PFAS exposures in the European participants are quite comparable to levels in America, so my concern is that our exposures to PFAS are making it difficult for us to avoid getting overweight.\u201d<\/p>\n

The study results are useful, too, for informing the ongoing work of the URI STEEP \u2013 Sources, Transport, Exposure & Effects of PFAS \u2013 Superfund Research Center, which employs research, applied science, student education and training, and outreach approaches to build community capacity for responding to PFAS pollution. PFAS, a large and decades-old family of chemicals, infiltrate many human and natural environments \u2013 they are colorless, tasteless, and odorless, and often are used to create barriers or stop liquids from seeping. The chemicals coat pizza boxes and microwave popcorn bags, nonstick cookware, and waterproof clothing, and stop stains from sinking into carpet and furniture.<\/p>\n

The heavily used \u201cforever chemicals\u201d have also leached into water, from marine habitats to drinking water resources, with STEEP committing significant effort toward ensuring sound science informs public dialogue about enhancing protections for supplies. \u201cThe hard science is the main tool the government has upon which to make changes that move us closer to either lessening or removing PFAS from our water, our lives, our environments,\u201d said Rainer Lohmann, a URI chemical oceanographer and STEEP research director. \u201cPFAS presents a long-term challenge, but we are making steady progress.\u201d<\/p>\n

And increasingly, said Lohmann and Grandjean, public policy discussions at the federal and state levels are focused on determining regulatory and legislative paths forward to potentially lower PFAS levels in drinking water sources across the country. \u201cThe EPA has recently proposed binding guidelines for water contamination,\u201d said Grandjean. \u201cI hope that the new regulation will be successful, and now I have an additional reason to hope.\u201d<\/p>\n
