A new study by Dartmouth College in New Hampshire US, has found evidence that suggests warmer sea surface temperatures may increase the ability of fish to accumulate mercury. The scientists studied the Killifish, found in most parts of the world, under varying temperatures in the lab and in salt marsh pools. The results of the study showed that fish in warmer water ate more but grew less and had higher methylmercury levels in their tissues, suggesting that increases in their metabolic rate caused the increased mercury uptake. This means that the inevitable warming of our oceans could present a higher risk to the health of some consumers of seafood as the mercury rises up the marine food chain.
