报告摘要:

Contaminants of emerging concern (CECs), such as pharmaceuticals and personal care products, are present in the aquatic environment and represent potential threats to both human and ecological health. Background information on CECs will be framed using our measurements in the Chesapeake Bay, which is the largest estuary in the United States. The first part of the talk will focus on the occurrence of CECs in an urban watershed that is not impacted by expected sources, such as wastewater treatment plants or animal feeding operations. We hypothesize that CECs are introduced to this watershed through leaking sewers. Given the detection of CECs in the aquatic environment, a need exists to improve CEC removal during wastewater treatment. The second part this talk will focus on the transformation of antibiotics by light-driven processes. Most antibiotics derive from a baseline pharmacophore substituted with different functional groups. We hypothesized that phototransformation of antibiotics results in changes at the functional groups and not the pharmacophore, effectively producing other antibiotics. These findings highlight the need for continued investigation both upstream and downstream of wastewater treatment plants to fully understand the occurrence, fate, transport, and toxicity of CECs in the aquatic environment.

Dr. Lee Blaney received his BS and MS degrees in Environmental Engineering from Lehigh University. He completed his PhD at the University of Texas at Austin and immediately joined the Department of Chemical, Biochemical, and Environmental Engineering at UMBC, where he is now an Associate Professor. At UMBC, Lee has established a research program focused on (1) the occurrence, fate, transport, and toxicity of contaminants of emerging concern in natural and engineered systems and (2) development of innovative technologies for resource recovery from agricultural and municipal waste. He is the recipient of the Maryland Outstanding Young Engineer Award, the NSF Career Award, and the AEESP Award for Outstanding Teaching in Environmental Engineering and Science. Lee is currently on sabbatical as a Visiting Professor at the Tsinghua University School of Environment.
