Urs Jans

Urs Jans is a **Professor** in the Department of Chemistry and Biochemistry at The City College of New York (CCNY). He is also affiliated with the Earth System Science and Environmental Engineering program. His research focuses on environmental chemistry, particularly the fate of organic contaminants in natural systems, kinetics of contaminant removal, and the degradation pathways of flame retardants and insecticides. Jans has extensively studied the reactivity of pollutants such as hexabromocyclododecane (HBCD), organophosphate pesticides, and brominated flame retardants with reduced sulfur species and iron oxides.

His work emphasizes environmental remediation strategies, including advanced oxidation processes like Fe-TAML/H₂O₂ treatments for micropollutant abatement. He has explored stereo- and isomer-specific reactions of persistent organic pollutants, contributing to understanding mechanisms of contaminant degradation in aqueous and sedimentary environments. Notable contributions include investigations into pesticide hydrolysis kinetics, the role of natural organic matter in contaminant fate, and the environmental behavior of legacy pollutants like DDT and chlordane in Long Island Sound sediments.

Jans' research integrates analytical techniques such as HPLC-MS/MS, NMR spectroscopy, and advanced adsorption studies to characterize contaminant transformation processes. While no specific awards are listed, his extensive publication record reflects a sustained commitment to advancing environmental chemistry and pollution control technologies.

His advising and grants section remains unspecified in available data, but his affiliations with interdisciplinary programs suggest collaborative work on environmental engineering and earth systems research. No lab or team affiliations are explicitly mentioned in the provided text.
