Mercury (Hg) is a global environmental pollutant that has been the cause of many public concerns. One particular concern about Hg in aquatic systems is its trophic transfer and biomagnification in food chains.

For example, the Hg concentration increases with the increase of food chain level. Fish at the top of food chain can accumulate high concentrations of Hg.

Applied radiotracer techniques for studying pollutant bioaccumulation in selected marine organisms 99 elevated in C. andromeda, a benthic species. High metal assimilation from ingested prey coupled with a strong retention in tissues indicates that over the long term, dietary intake might be the predominant source of metal contami.

Cochran also looks at the impact of Fukushima radiation carried directly to U.S. waters in ocean currents, and the effect of that radiation concentrated in the bodies of fish through bio-accumulation.
