Climate change may boost toxic mercury levels in sea life
Increased runoff shifts marine ecosystems, concentrating more of the contaminant in food webs, experiments suggest

MEDDLESOME MERCURY Increased runoff into Earth’s oceans could increase methylmercury concentrations in marine ecosystems by altering the food web, new laboratory tests show. Here a researcher adds methylmercury to a vat containing coastal microbes.
