New detoxification pathway for mercury in penguins

Life

An international team of scientists led by ESRF and CNRS scientists, the European Synchrotron, Grenoble, France, has found that emperor penguins detoxify mercury with both sulfur and selenium, a new pathway for a marine predator. This new detoxification pathway for mercury has been unveiled in a study published in the Journal of Hazardous Materials.
