Lampricide Photochemistry

Our group is currently studying the photochemical degradation mechanisms of two lampricides, 3-trifluoromethyl-4-nitrophenol (TFM) and 5-chlor-N-(2 chloro-4-nitrophenyl)-2-hydroxibenzamide (niclosamide), in natural waters. Large amounts of these compounds are routinely applied to tributaries of the Great Lakes in order to combat the invasive sea lamprey, yet little is known about their environmental fate.

Dissolved Organic Matter Characterization

Dissolved organic matter (DOM) plays an important role in many biogeochemical processes, including the carbon and nitrogen cycles, metal complexation and redox reactions, contaminant fate and transport, and microbial metabolism. For example, the colored fraction of DOM contributes to the photochemical transformation of numerous contaminants in sunlit surface waters. Our current research focuses on determining the size distribution of DOM using dialysis fractionation, and assessing the photochemical transformation potential of each size fraction.
