Comments on proposed endangerment finding on lead in aviation gas

In October of 2022, the Environmental Protection Agency (EPA) proposed an endangerment finding on leaded aviation gasoline, a critical step to regulate lead pollution from piston-engine aircrafts - the largest source of lead emissions in the country. The Agency said it will propose an endangerment finding on leaded aviation gas by the end of 2022 and finalize the endangerment finding in 2023. The endangerment finding is the first step before the EPA, and the Federal Aviation Administration (FAA), can regulate lead in aviation gasoline.

PFAS and PBDEs in traditional subsistence foods from Sivuqaq, Alaska

The Arctic is a hemispheric sink for both legacy and current use persistent organic pollutants (POPs). Once in the Arctic, POPs biomagnify in food webs, potentially reaching concentrations in high trophic level animals that pose a health concern for people who subsist on those animals. Indigenous Peoples of the Arctic may be highly exposed to POPs through their traditional diets. The objective of this study was to assess concentrations of polybrominated diphenyl ethers (PBDEs) and per- and polyfluoroalkyl substances (PFAS) in tissues of traditionally harvested foods from Sivuqaq (St. Lawrence Island), Alaska.


CHE-Alaska presents: The Urgent Need to Address Toxic PFAS Chemicals to Protect Drinking Water and Public Health

On January 25th at 1pm AKST CHE-Alaska hosted a webinar on PFAS legislation and states taking the lead.  The Urgent Need to Address Toxic PFAS Chemicals to Protect Drinking Water and Public Health. Per- and polyfluoroalkyl substances (PFAS) are toxic chemicals widely used in consumer products, industrial firefighting foams used on military bases and airports, and can be found in drinking water throughout Alaska and the US. In Alaska, the use of PFAS-based firefighting foams has contaminated the drinking water of communities from the North Slope to southeast Alaska. CHE-Alaska is proud to present: The Urgent Need to Address Toxic ...
