One Health assessment of persistent organic chemicals and PFAS for consumption of restored anadromous fish.

Background: Restoration efforts have led to the return of anadromous fish, potential source of food for the Penobscot Indian Nation, to the previously dammed Penobscot River, Maine.

Objective: U.S.

Risks from mercury in anadromous fish collected from Penobscot River, Maine.

Levels of total mercury were measured in tissue of six species of migratory fish (alewife, American shad, blueback herring, rainbow smelt, striped bass, and sea lamprey), and in roe of American shad for two consecutive years collected from the Penobscot River or its estuary. The resultant mercury levels were compared to reference doses as established in the U.S.
