What seal pups can reveal about the effects of mercury exposure
Phys.org ·
The Brief
- Marine mammals along the Pacific Coast of North America are exposed to contaminants such as mercury, not only through their prey.
- Mercury can move through marine food webs and biomagnify, becoming more concentrated at higher trophic levels.
- The story reports on what seal pups can reveal about the effects of mercury exposure.
Why it matters
Seal pups can serve as indicators of contaminant exposure in coastal marine food webs, which matters for monitoring ecosystem health and the risks mercury poses to wildlife.
Who’s affected
- marine biologists and wildlife researchers
- ecotoxicologists and environmental managers on the Pacific Coast

Marine mammals living along the Pacific Coast of North America encounter more than the fish, crustaceans, cephalopods and other marine mammals that live around them. Because contaminants such as mercury can move through marine food webs and biomagnify—becoming more concentrated…
