Exposure to environmental immunotoxicants may worsen outcome of SARS-CoV-2 infection
News
2 Nov 2020 | News Medical Life Sciences
Increased plasma PFBA levels were associated with more severe COVID-19 prognosis, even after adjustment for comorbidities, sex, age, origin, sampling time, and location. Although PFBA levels in plasma were lower than most PFAS studied, PBFA accumulates in the lungs, and hence it is suspected that PBFA exposure may contribute to the severity of disease.

State PFAS enforcement against the federal government – irresistible force meets immovable object?
News
30 Oct 2020 | Fox Rothschild
The Department of Defense, the entity that in many states is seen as a significant potentially responsible party with respect to PFAS contamination related to AFFF usage, has raised numerous defenses and objections to state enforcement and litigation efforts, from sovereign immunity to arguments based on the absence of PFAS from the list of CERCLA hazardous substances, to challenges to the validity of state regulatory standards for PFAS.
