Hornbuckle Receives $347,000 NSF Grant For Environmental Studies

Keri Hornbuckle, associate professor in the UI College of Engineering Department of Civil and Environmental Engineering, has received a $347,000 grant from the National Science Foundation (NSF) to acquire instruments to advance UI environmental studies.

The equipment, including a triple quadrupole tandem mass spectrometer with gas chromatograph (GC/MS/MS), will permit rapid analysis of trace levels of organic contaminants in complex mixtures.

Hornbuckle notes that the equipment will be housed in the Environmental Engineering and Science & W.M. Keck Phytotechnologies Laboratories (EES-KPL) and will be available to researchers throughout the university.

"The equipment is to support studies on organic compounds in the environment, including such substances as pesticides, consumer products, and industrial pollutants" Hornbuckle says. "We are excited to add this new technology to our already strong analytical capabilities for studies on environmental processes." She adds that the equipment will support existing studies of volatilization of PCBs from contaminated water, fate of synthetic fragrances in natural systems, and investigations of the source and risks of fluorinated surface coatings in humans."

Co-principal investigators on the project are Jerald Schnoor, professor of civil and environmental engineering, and Hans Lehmler, associate research scientist in the College of Public Health Department of Occupational and Environmental Health. The grant total includes matching funds in the amount of 30 percent from the UI Office of the Vice President for Research.
