(California) and Jennifer Arblaster (Vermont) will present on risk assessments associated with per and polyfluoroalkyl substances (PFAS
) at the Society of Environmental Toxicology and Chemistry (SETAC) North America Focused Topic Meeting on 'Environmental Risk Assessment of PFAS
' at the Durham Convention Center in Durham, North Carolina from August 12-15, 2019.
Participants had to have lived in their home full-time, used their well as their primary drinking water source before GenX detection (2017), and had no known occupational PFAS
With the Senate considering whether to confirm him as EPA chief, Democratic and Republican lawmakers have pressed Wheeler to establish mandatory limits for PFAS
in public water systems.
Part of what makes the situation so difficult is that the PFAS
class of chemicals actually includes thousands of unique compounds.
"If these sources are right, the EPA is essentially telling the more than 110 million Americans whose water is likely contaminated with PFAS
: 'Drink up, folks,'" David Andrews, Ph.D, a senior scientist with the nonprofit Environmental Working Group, reportedly said. "The most efficient and equitable way to remove these chemicals from the nation's drinking water supply is to use the agency's authority to set legal limits...

Humans are exposed to PFAS
through contaminated soil, food, water, and air.
have been in production since the 1940s, and there are about 3,500 different types.
There was no significant correlation for baseline PFAS
concentrations with concurrent body weight or weight loss during the first six months after multivariate adjustment.
EPA) issued the following drinking water lifetime health advisory values for two PFAS
compounds: 70 ng/L (or parts per trillion) for both perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
