New Tool Monitors a Flame Retardant in Sediment
Research Brief - October 2020
Researchers at the University of California, Davis (UC Davis) Superfund Research Program (SRP) Center developed a new, inexpensive tool to reliably detect small amounts of tetrabromobisphenol A (TBBPA) in environmental samples. TBBPA is a flame retardant commonly found in household dust, soil, water, sewage, sludge, and sediments.
Enzyme may play key role in obesity-related leaky gut

Early SRP Collaboration Guides Potential Treatment Options for Disorders of the Eye
SRP News Page - August 2018
Researchers are one step closer to determining how to prevent blindness from occurring in mice with macular degeneration and diabetic retinopathy, two diseases that affect the eye. This work stems from a collaboration dating back nearly 20 years between SRP-funded researchers Bruce Hammock, Ph.D., from the University of California, Davis, and Bernhard Hennig, Ph.D., from the University of Kentucky.
Researchers Identify Compounds that Reduce Abnormal Blood Vessel Growth in the Eye
Research Brief - July 2018
Scientists have identified key compounds produced when the body metabolizes omega fatty acids that can reduce the severity of age-related macular degeneration (AMD) in mice. By increasing these lipid metabolites and preventing them from degrading, the researchers reduced abnormal blood vessel growth, in part by regulating the movement of inflammatory immune cells into the retina.
Millions of dollars saved by NIEHS-funded technologies
Environmental Factor - July 2018
More than $100 million was saved through the adoption of tools supported by the Superfund Research Program (SRP), according to a commentary published June 15 in the journal Environmental Health Perspectives. The tools also led to additional benefits to society, including hazardous substance remediation and site monitoring.
Enzyme plays key role in Parkinson's disease
Paper of the Month - July 2018
New research by NIEHS grantees and colleagues suggested an enzyme in the brain plays a key role in Parkinson's disease (PD). Scientists demonstrated that inhibiting the enzyme soluble epoxide hydrolase (sEH) in mice helped curb the inflammation associated with the development and progression of PD.
Enzyme plays key role in Parkinson's disease and inflammation
Environmental Factor - June 2018
New research partially funded by NIEHS suggests an enzyme in the brain plays a key role in Parkinson's disease (PD). Scientists demonstrated that inhibiting an enzyme known as soluble epoxide hydrolase (sEH) can help curb the inflammation associated with the development and progression of PD.
SRP Grantee Presents NIEHS Seminar on Clinical Intervention for Pain
SRP News Page - April 2018
Renowned scientist and Superfund Research Program (SRP) grantee Bruce Hammock, Ph.D., was invited to present the Immunity, Inflammation, and Disease Laboratory Special Seminar at NIEHS on March 28, 2018. Hammock's talk focused on neuropathic pain, which is caused by damage or disease affecting the body's sensory system, and how findings from his lab are being translated into clinical interventions.
Possible explanation for male and female cardiovascular differences
Paper of the Month - March 2018
NIEHS grantees discovered that estrogen can block the function of soluble epoxide hydrolase (sEH), an enzyme in cells that degrades chemically stable fatty acid metabolites. Because inhibition of sEH can be cardioprotective, this finding may help explain why women generally have a lower incidence of cardiovascular disease than men.
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.
Survival of the resilient: rapid killifish evolution evades pollution
Environmental Factor - January 2017
A study published Dec. 9 in the journal Science and funded in part by NIEHS sheds light on genetic variability that may explain the survival of killifish in four polluted environments on the U.S. eastern seaboard. A team led by Andrew Whitehead, Ph.D., an NIEHS grantee at the University of California at Davis (UCD), sequenced the entire genome of nearly 400 killifish from eight sites along the Atlantic coast and reported that changes in genes in the aryl hydrocarbon receptor (AHR) pathway might hold the key to adaptation.
FDA ban on antibacterials in soaps informed by SRP research
Environmental Factor - October 2016
The U.S. Food and Drug Administration (FDA) issued a rule Sept. 2 banning 19 antibacterial chemicals as ingredients in over-the-counter (OTC) antibacterial hand and body washes. Development of the final rule was informed by research that included several studies from scientists supported by the NIEHS Superfund Research Program (SRP).
Anti-inflammatory chemical may offer new tool for depression treatment
Paper of the Month - May 2016
An NIEHS grantee and colleagues discovered that a chemical inhibitor of the soluble epoxide hydrolase (sEH) enzyme may be a new tool to treat depression. The enzyme plays a key role in inflammation, which is involved in depression.
