Description

The National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) produces a monthly Research Brief Podcast that highlights the research of SRP grantees. The SRP is a network of university grants that seek solutions to the complex health and environmental issues associated with the nation's hazardous waste sites. The research conducted by the SRP is a coordinated effort with the Environmental Protection Agency, which is the federal entity charged with cleaning up the worst hazardous waste sites in the country.

Prenatal Benzene Exposure Disrupts Immune Defenses During Early Development
2026/09/25
Scientists funded by the NIEHS Superfund Research Program discovered that exposure to benzene during pregnancy, even at low levels, may alter how a child's immune system develops. The research team, led by Gil Mor, Tracie Baker, and Jennifer Straughen, of the Wayne State University SRP Center, compared genetic responses across human placental tissue, pregnant mice, and developing zebrafish. They discovered that prenatal benzene exposure triggers a series of immune reactions, causing immune cells to deploy harsh chemical defenses in the placenta even when no infection is present.
Zebrafish Model Reveals PCB Byproducts Trigger Developmental Toxicity
2026/08/28
Scientists funded by the NIEHS Superfund Research Program, or SRP, discovered that, as PCBs are metabolized in the body, they trigger unique neurobehavioral and structural abnormalities. The study was led by Nicole Breese, Ph.D., a postdoctoral researcher at the University of Iowa SRP Center. Breese received a K.C. Donnelly Externship from SRP to travel to the Oregon State University SRP Center to learn how to use a zebrafish screening platform to complete this work.
Glazing Technique Improves 1,4-Dioxane Destruction
2026/08/07
Scientists funded by the NIEHS Superfund Research Program (SRP) developed a new strategy to effectively break down stubborn chemicals in water. Researchers at the Yale University SRP Center, led by Jaehong Kim, Ph.D., used advanced engineering approaches to create a stable and reusable material that targets specific pollutants.
Age-Dependent Effects of NDMA Exposure Show Unique Susceptibility of Juvenile Mice
2026/07/10
A study in mice funded by the NIEHS Superfund Research Program (SRP) reported that juvenile mice may be more susceptible to the damaging effects of N-nitrosodimethylamine (NDMA) exposure than adult mice. Experiments that artificially increased cell growth and division also show that susceptibility may be driven by cell division during exposure.
Dual-Action Bioaugmented Sorbents Optimize Groundwater Cleanup
2026/06/05
A new study may help improve cleanup strategies for groundwater and sediment contaminated with persistent chlorinated organic pollutants. Funded by the NIEHS Superfund Research Program, researchers at the University of Maryland Baltimore County used modeling tools to better understand and optimize their cleanup technology that combines pollutant-degrading bacteria with an activated carbon sorbent, called bioaugmented sorbents.
Linking Early-Life Lead Exposure with Cognitive Function Later in Life
2026/05/08
People with higher lead exposure before birth may have lower cognitive function in late adulthood, according to researchers from the Harvard School of Public Health Superfund Research Program (SRP) Center. This finding was most significant for women exposed to lead during the second trimester.
New Tool Targets Complex Groundwater Pollutants
2026/04/03
Researchers funded by the NIEHS Superfund Research Program developed a new biocatalyst technology to clean up chlorinated hydrocarbons, or CHCs, a large class of persistent groundwater pollutants.
Building Better Models to Study Air Pollution and Lung Health
2026/03/13
SRP Researchers developed an advanced cell culture model that better represents the human lung.
Improving Chemical Cleanup of Contaminated Groundwater
2026/02/27
SRP Researchers uncovered how underground conditions influence the success of chemical oxidation-based groundwater cleanup.
Urine Test May Detect Uranium Build Up Before Irreversible Injury
2026/02/13
Uranium exposure leaves a fingerprint in the body that could help identify kidney damage before it becomes irreversible, according to an NIEHS SRP-funded study in mice.
Nanoparticles Help Plants Clean Up “Forever Chemicals”
2025/10/22
Scientists funded by the NIEHS Superfund Research Program developed a novel material that enhances the ability of plants to remove PFAS from soil and water.
Dioxin-Like Compounds Shift the Balance of White Blood Cells
2025/08/27
Dioxin-like compounds can alter how white blood cells develop and do so in ways that current risk assessment methods fail to predict, according to a study from the Michigan State University Superfund Research Program Center.
Demonstrating a Pilot System to Electrochemically Remediate Groundwater
2025/06/11
Researchers partially funded by the NIEHS Superfund Research Program (SRP) designed a scaled-up electrochemical system that combines electricity with the mineral pyrite, a mineral commonly found in the environment, to continuously remove organic and heavy metal contaminants from groundwater for a year. The study was led by Akram Alshawabkeh, Ph.D., from the Northeastern University SRP Center, and Kitae Baek, Ph.D., from Jeonbuk National University in Korea.
Mechanism Linking Preconception Arsenic Exposure and Diabetes in Offspring Revealed
2025/05/14
Exposure to inorganic arsenic before conception can trigger changes in gene activity that are passed down to offspring and increase their risk of developing diabetes, according to a study in mice funded by an NIEHS individual research grant and by the NIEHS Superfund Research Program. These changes, known as epigenetic changes, alter how genes work without changing the genes themselves. In this study, the researchers looked at a type of change called CpG methylation.
Machine Learning Creates More Complete Picture of Groundwater Contamination
2025/04/02
Machine learning algorithms can fill gaps in sparse or incomplete groundwater datasets, according to researchers partially funded by the NIEHS Superfund Research Program. The study tested the ability of two algorithms to help scientists analyze co-occurring pollutants in groundwater by filling in missing field data points and was led by researchers from Arizona State University, Harvard University, and North Carolina State University.
