Serum per- and polyfluoroalkyl substance (PFAS) levels and health-related biomarkers in a pilot study of skiers in New England.

Background: Per- and polyfluoroalkyl substances (PFAS), synthetic chemicals with adverse health effects, are used extensively in consumer products. Ski waxes, applied to the base of skis, contain up to 100% PFAS by mass, but exposure and health effects are poorly characterized.

Objectives: Our objectives were to quantify serum PFAS concentrations among skiers and explore associations with reported ski wax use and biomarkers of cardiometabolic, thyroid, and immune health.

Levels and trends of persistent organic pollutants in human populations living in the Arctic.

The Arctic Monitoring Assessment Program (AMAP) is tasked with monitoring and assessing the status of environmental contaminants in the Arctic, documenting levels and trends, and producing science-based assessments. The objectives of this paper are to present the current levels of persistent organic pollutants (POPs) across the Arctic, and to identify trends and knowledge gaps as detailed in the most recent AMAP Human Health Assessment Report. Many Arctic populations continue to have elevated levels of these contaminants, and the highest levels of POPs were observed in populations from Greenland, Faroe Islands, and Nunavik (Canada), as well as populations in the coastal Chukotka district (Russia) for legacy POPs only.

Assessing awareness and compliance with fish consumption advisories on the upper Hudson River: Implications for risk management of the Hudson River Superfund site.

Polychlorinated biphenyls (PCBs) are a common environmental contaminant. The NYS Department of Health (DOH) issues fish consumption advisories to limit consumption of PCB-contaminated fish. Fish consumption advisories are utilized as institutional controls within the Hudson River Superfund site to limit exposure to PCBs.

The injustice of risk avoidance: the limitations of fish consumption restrictions as institutional controls for superfund sites.

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is a landmark environmental policy. It broadly empowers the federal government to manage hazardous waste sites to ensure the protection of human and environmental health. In many ways, CERCLA is the result of the environmental justice movement, and public concern about hazardous sites.

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.

Organochlorine and metal contaminants in traditional foods from St. Lawrence Island, Alaska.

Marine mammals (bowhead whale, walrus, and various seals) constitute the major component of the diet of the Yupik people of St. Lawrence Island, Alaska. St.
