SUMMARY:Students Ask Scientists
DESCRIPTION:Mercury is a dangerous neurotoxin that can be found in high concentration in fish across the globe. Surprisingly\, mercury levels in the environment are quite low compared to other forms of pollution. However\, microorganisms in the environment can convert the mercury that is released into the environment into another form of mercury called methylmercury. This methylmercury form is capable of two processes called bioaccumulation and biomagnification which lead to high concentrations\, often to toxic levels\, in fish. \nThis research focuses on understanding these microorganisms: Who are they? Where do they live? What do they eat? Why do they make mercury more toxic? This research was conducted in a wide range of environments\, from the Great Lakes down to test tubes in the laboratory. \nJoin Ben Peterson\, an Assistant Professor in the School of Freshwater Sciences at the University of Wisconsin−Milwaukee\, for a look into his research that uses microbes as a window into understanding how contaminants impact aquatic ecosystems and human health. \nPre-register HERE. \nFeatured Scientist\nOriginally from Wisconsin\, Ben received his PhD in Environmental Chemistry and Technology from the University of Wisconsin−Madison investigating mercury methylating bacteria in freshwater lakes and wetlands. He then worked as a postdoctoral scholar at the University of California−Davis\, working on methylmercury formation in different ecosystems across the US\, from the permafrost of northwest Alaska to the coastal wetlands of the Florida Everglades.
