Research

Dr. Muir's research interests are focus broadly on the environmental chemistry and biogeochemistry of persistent organic contaminants, mercury and other metals. A major focus is the development or refinement of analytical methodologies for newly emerging persistent chemicals such as fluorinated surfactants and brominated flame retardants. This involves use of liquid chromatography-tandem mass spectrometry and high resolution mass spectrometry. His major interests center on understanding bioaccumulation and bioavailability of persistent and bioaccumulative chemicals in the aquatic and terrestrial environments under field and laboratory conditions with special emphasis on food chain transfer. Field sites are in the Arctic and sub-arctic regions of Canada as well as in the Great Lakes. He has also worked on projects in Africa and the southeastern USA and collaborates extensively with scientists in the USA (Alaska), Denmark (Greenland), Norway, Sweden and the UK. Much of this work is done by graduate students and post-doctoral fellows, located at Canada Centre for Inland Waters (Burlington, ON) in collaboration with university colleagues. They are supported by technical personnel within the PSEx section in Burlington. He currently co-supervises four graduate students in Environmental Biology at University of Guelph and serves on the advisory committees of three PhD students in Chemistry at University of Toronto, as well as students at University of Waterloo (Biology), University of Northern British Columbia, and UniversitÚ Laval (Biologie).
