The toxicology of soluble heavy-metal bioavailable material is a well understood area of research, and can bioaccumulate in humans several times higher than background if a food chain allows biomagnification of a contaminant.

I would recommend studying the story of Polychlorinated biphenyls in whales, Mercury levels in salmon, and PFAS in the Veritasium hosts blood.
