The natural environment has an astounding capacity to assimilate and process chemicals that continuously bombard it due to human activity, but this capacity has limits. As a result, legacy pollutants still exist in our waterways and new emerging contaminants continue to be discovered. With an eye on the future, nanomaterials are being developed rapidly, yet their persistence in the environment and affect on the environment remain largely unknown. In this presentation, environmental processes that control the fate of several chemicals and nanomaterials in the environment will be discussed. In the first example, the properties and photoreactivity of fullerene nanomaterials in the environment will be discussed. In the second example, the persistence of numerous polycyclic aromatic hydrocarbons (PAHs) within a nonaqueous phase liquid (NAPL) that has contaminated a river sediment in northwest Indiana for decades will be discussed. In the third example, the measurement of steroid hormones in the water in agricultural ditches adjacent to manure-applied farm fields will be presented. And finally, a few slides regarding drinking water quality in rural Colombia with be presented.
Chad Jafvert received his Ph.D. from the U. of Iowa in 1985 and was awarded a NRC postdoctoral fellowship to work at the U.S. EPA Research Laboratory in Athens, GA. After one year, he was hired by the EPA at the same lab, where he worked until joining the faculty at Purdue in 1991. Dr. Jafvert’s primary research interests are the chemical and physicochemical fate processes of anthropogenic substances in natural and engineered environments. He has published widely on octanol-water, soil-water and sediment-water phase distribution processes of organic chemicals, including organic cations and anions. His recent interests include: remediation strategies for contaminated sediments; aquatic photochemistry of pollutants including carbon-based nanomaterials and flame-retardant compounds; real-time continuous water quality monitoring, and drinking water treatment in rural areas of developing countries. He has served as a reviewer of manuscripts, proposals, and reports for over 30 different journals and organizations. He is currently a member of the EPA National Food Quality Protection Act (FQPA) Science Review Board, and in 2013, he was honored as a guest professor by the President of Southeast University, Nanjing, China. He has supervised 13 completed Ph.D. and 10 thesis M.S. students, has served on the committees of over 60 other students, and has supervised 5 postdoctoral research associates. He has published over 100 papers and documents searchable in citation indexes. Nine of his former graduate students or postdoctoral associates are faculty members at universities in the U.S., Taiwan, South Korea, and China.
