Urs Jans’ research interests lie in the field of chemical transformations of synthetic compounds in natural environments and in engineered systems. During his graduate education, he conducted research on the transformation of ozone by soot particles. As a postdoctoral associate and junior faculty member at CCNY, he investigated the reduction and substitution reactions of organophosphorus insecticides (e.g., chlorpyrifos, methyl-parathion), organophosphorus flame retardants (e.g., tris(chloroethyl)phosphate and brominated aliphatic flame retardants (e.g., hexabromocyclododecane) in sulfate reducing environments. In recent years, he also started to analyze the concentration of persistent organic pollutants in sediments cores as a tool to elucidate the fate of persistent contaminants in the environment. In addition, he determined the concentration of organic compounds (e.g., PAHs) in aerosol particle collected in New York City.
