Dr. Michael B. Parsons
Research Scientist - Studies the geochemistry of metals and mine wastes, and develops new methods to characterize and mitigate the environmental impacts of metal mining activities.
Geological Survey of Canada (Atlantic), Dartmouth, Nova Scotia
CURRENT S&T / RESEARCH
Dr. Parsons is currently working under NRCan’s Environmental Geoscience Program where he is developing new methods to characterize the risks associated with metal mine tailings, and optimizing remediation strategies to protect ecosystems and human health.
Characterizing the geochemical and mineralogical controls on arsenic release from historical gold mine tailings under various remediation scenarios.
Developing new methods for determining baseline metal concentrations in soils, sediments and surface waters from mineralized areas.
Identifying key controls on the transport and fate of metals, radionuclides, and rare earth elements from decommissioned uranium and niobium mine tailings.
Studying the effects of climate change on baseline geochemical conditions near metal mines in Northern Canada.
PROFESSIONAL ACTIVITIES / INTERESTS
Areas of expertise: geology; environmental geochemistry; analytical chemistry.
Interests: geochemistry and mineralogy of metal mine wastes; determination of baseline concentrations at mine sites; cycling of metals in freshwater and marine sediments; geochemical modeling; speciation of redox-sensitive elements.
Dr. Parsons holds Adjunct Professorships at Dalhousie and Queen’s universities and regularly co-supervises students who are involved in his research activities.
Parsons’ studies have reduced ecosystem and human health risks associated with metals in the environment, and provided a sound scientific basis for improved environmental quality guidelines and for managing contaminated sites.
