## In 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.
