Climate changes may lead to more poisonous mercury in plankton
(Umea University) Global warming is expected to increase runoff and input of organic matter to aquatic ecosystems in large regions of the Northern hemisphere including the Baltic Sea. Research performed in Sweden is now indicating a sevenfold increase in poisonous methylmercury in zooplankton as a consequence. This increase is due to an altered structure of the aquatic food web. The study has been published in the journal Science Advances.
