Flegal Laboratory: Biogeochemical Cycling of Trace Metals
Our group investigates the biogeochemical cycling of trace metals in the environment on local, regional and global scales. Our current studies include isotopic composition analyses to identify sources of industrial lead in the North Pacific, South Pacific, and Southern Ocean; processes influencing the formation and flux of monomethylmercury in the coastal zone; natural and anthropogenic sources of hexavalent chromium in groundwater; isotopic composition analyses to trace cadmium fluxes in the California Current Upwelling Zone; the remobilization of historic metal contamination by forest fires in the US, Chile, and Australia; and the environmental impact of mining and smelting operations in the US, Australia and Mongolia. We’re also involved in a few studies of the sources contaminant metals in consumer products. We hope the results from this research will contribute to efforts to reduce the adverse impacts of toxic metals on environmental and human health.Dr. Flegal accepts graduate students from the METX, Chemistry, Earth and Planetary Sciences, and Ocean Sciences graduate programs.
