Hongbing Sun

Dr. Hongbing Sun received his doctorate from Florida State University in 1995, specializing in hydrology and water and soil quality related issues. He currently holds the rank of Professor of Geological and Environmental Sciences. Hongbing’s broad research interests include environmental health, hydrogeology, soil science and quality, and coastal oceanography. His current research focus involves issues related to the mobilization or arsenic, lead, and mercury due to the application of winter road salt, the associations of Parkinson’s and Alzheimer’s diseases with soil selenium, sulfur, and other anti-oxidants, and the association of multiple sclerosis with temperature-heat events. Most recently, Hongbing has been investigating the impact of water contamination (heavy metals and organophosphate pesticide) in the Mississippi and Delaware Rivers on the prevalence of hypertension and colon cancer in those watersheds, and the relationship among blood mercury and lead, and liver function-biomarkers with environmental exposure to those elements.
