A relatively low blood level of PFAS can still be dangerous

A committee of the prestigious National Academies of Sciences, Engineering and Medicine this week recommended that the blood of perhaps tens of millions of Americans be tested for the presence of the ubiquitous “forever” chemicals collectively called PFAS. Among other things, the National Academies Committee concluded that PFAS in the blood at a concentration between 2 and 20 nanograms per milliliter is of concern.

A nanogram is a billionth of a gram and a milliliter is a thousandth of a liter.

Suffice it to say, this is a very, very small amount.

What do the national academies recommend if one has such concentrations, or more, of PFAS in the blood? Reduce your exposure to PFAS. I think this could be good advice for everyone.

The same day, the media reports the alarm of the national academies concerning the PFAS, Inside the EPA reports that the EPA is still struggling to get to any of the destinations identified in its PFAS roadmap, including the list of any PFAS as Federally Regulated Hazardous Substances. When the EPA released its roadmap, I expressed concern that the road ahead was strewn with pitfalls (https://insights.mintz.com/post/102h8ro/epas-ambitious-pfas-road-map-is-…), and most EPA delays are due to circumstances beyond its control.

Still, it’s concerning that scientists are sounding louder and more frequent alarms about truly minute concentrations of PFAS in our bodies, yet PFAS remain totally unregulated under federal law. In the meantime, states and courts continue to fill the void and confusion and growing fear continue to reign.

But the agency again missed its final deadline for releasing the first proposal, after telling the Unified Agenda in the spring that it would release the proposal by June this year, after repeated delays. An EPA spokeswoman did not respond to questions about why the proposal was delayed, saying only that publishing the CERCLA rule “remains a top priority for the EPA. We are working as quickly as possible.” possible to publish it,” she said.
