SRP Welcomes New and Returning Multiproject Centers
SRP News Page - April 2020
The SRP welcomes 11 new and returning multiproject Centers. SRP Centers consist of several projects and cores, designed to address research questions that contribute to the Center's overall research focus. These NIEHS-funded grants are the mainstay of the program, where transdisciplinary teams of scientists and engineers working in different fields tackle complex but targeted problems in environmental health.
Jerry Schnoor Receives 2019 ACS Award for Innovative Plant-Based Cleanup Advances
SRP News Page - May 2019
Jerry Schnoor, Ph.D., a University of Iowa Superfund Research Program (SRP) Center project leader, received the American Chemical Society (ACS) Award for Creative Advances in Environmental Science and Technology during the ACS Spring 2019 National Meeting, held March 31 - April 4 in Orlando, Florida.
Study Sheds Light on Breakdown of PCBs to Potentially Harmful Metabolites in Humans
Research Brief - May 2019
New research out of the University of Iowa Superfund Research Program (SRP) Center identified specific cytochrome P450 (CYP) enzymes and underlying mechanisms involved in the breakdown, or metabolism, of polychlorinated biphenyls (PCBs) into compounds that may be more toxic.
Passive Samplers Tackle PCB Flux
Research Brief - March 2019
Researchers from the University of Iowa Superfund Research Program (SRP) Center have developed a method to measure the movement, or flux, of polychlorinated biphenyls (PCBs) from water to air using passive sampling devices.
Kitchen cabinets emit potentially harmful PCBs
Paper of the Month - June 2018
NIEHS grantees discovered that finished cabinetry is a predominant and previously unknown source of airborne polychlorinated biphenyls (PCBs) in residential homes.
Iowa SRP Center Model Enables Accurate Air Pollutant Measurements
SRP News Page - March 2018
The University of Iowa Superfund Research Program (SRP) released a Web-based application to help researchers and regulators more accurately determine pollutant concentrations in air using passive air samplers. The application is designed to predict the sampling rates and volumes captured by passive air samplers equipped with polyurethane foam (PUF-PAS), which are frequently used to capture and measure airborne persistent organic pollutants (POPs).
Airborne PCBs in urban and rural U.S. schools
Paper of the Month - August 2017
An NIEHS-funded study showed that polychlorinated biphenyls (PCBs) are present in older schools and that the likely source is outdated building materials, including window caulking and light ballasts. The multi-year study is one of the largest to examine airborne PCBs in schools.
Risk e-Learning Web Seminar Series on Analytical Tools and Methods a Big Success
SRP News Page - July 2017
In a spring 2017 three-part Risk e-Learning Web seminar series titled 'Analytical Tools and Methods,' the Superfund Research Program (SRP) highlighted groundbreaking chemical detection, measurement, and fate and transport modeling techniques developed by grantees. In total, this series attracted 1,209 live participants, 6,543 online archive views, 1,419 audio podcast downloads, and 14,596 video podcast downloads.
SRP Researchers Shine at American Chemical Society Meeting
SRP News Page - May 2017
Superfund Research Program (SRP) grantees from all over the country gathered for the 2017 American Chemical Society (ACS) meeting in San Francisco this April. Presentations and posters by SRP grantees highlighted innovative SRP-funded research including technologies to detect and remediate potentially harmful chemicals in the environment.
Switchgrass and Bacteria Work Together to Remove PCBs from Soil
Research Brief - April 2015
Researchers at the University of Iowa Superfund Research Program (Iowa SRP) Center have found that switchgrass, a plant native to central North America, can effectively remove polychlorinated biphenyls (PCBs) from contaminated soil.
Emerging concerns with PCBs in schools draw hundreds to SRP webinars
Environmental Factor - June 2014
An international group of more than 300 people gathered, via webinar, April 21 and April 28, to discuss the issues related to the presence of polychlorinated biphenyls (PCBs) in schools.
Understanding the Movement of Inhaled PCBs in the Body
Research Brief - April 2014
Researchers at the University of Iowa Superfund Research Program (Iowa SRP) have found that a form of polychlorinated biphenyls (PCBs), known as PCB11, is completely absorbed and then rapidly eliminated from the body when inhaled.
