SRP-funded researchers at the University of Alabama at Birmingham (UAB) found that heavy metal exposure disrupts a network of lipids in lung and airway cells called sphingolipids. Nestled in the cellular membrane, sphingolipids are one of the most abundant and complex types of lipids found across the human body, playing a role in cell growth, stress response, signaling, and survival.

SRP-funded researchers at Villanova University identified specific molecular structures that improve the ability of biochar to trap and destroy the groundwater contaminant 1,2,3-trichloropropane (TCP). These structures are called N groups, because they contain nitrogen and behave in similar ways.

Adding two widely available fertilizers can form minerals that may remove arsenic from underground water reservoirs, according to a study by researchers from Columbia University SRP Center. The method uses chemical reactions to filter out arsenic, a naturally occurring element that can leach into aquifers and contaminate groundwater.

TAMU SRP Center researchers created a new method to identify points of departure (PODs), or the lowest dose of a chemical that triggers a biological response.

Scientists at the Columbia University SRP Center reported a link between arsenic in drinking water and type 2 diabetes. According to the authors, the findings underscore the need for considering type 2 diabetes as an adverse health outcome when developing arsenic standards for drinking water.

Exposure to newer PFAS compounds, often assumed to be less toxic than their older counterparts because they accumulate less in the body, may still harm the liver, according to a study in mice from the NC State SRP Center. Newer PFAS compounds, like GenX and Nafion byproduct 2 (NBP2), are not well studied but are increasingly detected in the environment and in drinking water.

Researchers from the University of Arizona SRP Center revealed how cadmium and arsenic, two toxic metals that frequently occur in soils together, may interact inside the human body. The effects of each individual metal on the digestive system have been studied, but little is known about how the contaminants behave when ingested simultaneously.

In a new study, researchers at the TAMU SRP Center developed a three-dimensional cell culture model of a placenta and gained insights into the effects of certain endocrine-disrupting chemicals (EDCs), compounds that mimic hormones in the body, on maternal and fetal health. The team adapted a new technology called organ-on-chip (OOC) — interconnected human cells grown inside a small device — to represent the tissues of a second-trimester placenta.

Researchers at the University of Rhode Island SRP Center used innovative sampling methods to document PFAS sources along the Pawcatuck River in Westerly, Rhode Island. They found that PFAS are ubiquitous in the river, retired and active textile mills are believed to be major contributors, and river dynamics may influence the amount of PFAS entering the Atlantic Ocean.

Prenatal exposure to the environmental contaminant benzene may have dose- and sex-dependent effects on several gene pathways in the brain and gonads, or sex organs, of adult zebrafish, according to research partly funded by SRP at Wayne State University. Because zebrafish and humans share certain genes, these findings may point to ways that prenatal benzene exposure affects humans.

Taking a page from culinary arts, researchers at the Harvard University SRP Center, led by Paul Westerhoff, developed a new method inspired by French cooking to improve the ability of carbon block filters to remove arsenic from water. This technique may offer a cheaper and more practical solution for people to reduce arsenic exposure at the tap.

Researchers at the University of Iowa SRP Center identified specific PCB compounds, or congeners, associated with diabetes risk. The authors also calculated the lowest concentration, known as threshold, that resulted in a biological change related to diabetes.

Researchers from the Louisiana State University SRP Center reported sophisticated methods to improve how environmentally persistent free radicals (EPFRs) are generated in the lab and used to study potential health consequences.

Exposure to lead mixtures with other chemicals can impair mitochondrial function, according to Duke University SRP Center researchers. Mitochondria, special compartments found in the cells of most organisms, play a large role in energy production and metabolism. While it is known that lead can disrupt mitochondrial function by replacing calcium in cellular processes, there has not been much research on co-exposures with other environmental contaminants.

Domestic animals like horses and dogs may help provide insight into PFAS exposure outside and inside the home, according to NIEHS-funded researchers at North Carolina State University SRP Center. Known as sentinel animals, horses and dogs are sensitive to environmental hazards like PFAS and can act as effective monitors for contaminants. PFAS are a class of chemicals linked to many health issues, including diabetes and immune dysfunction.

Exposure to PFAS can make it harder to keep weight off after dieting, according to NIEHS-funded researchers at The University of Rhode Island SRP Center. PFAS are widespread in the environment and have been linked to a large range of serious health issues, including harming metabolism and increasing obesity.

Exposure to volatile organic compounds (VOCs) is associated with increased risk of high blood pressure among Black adults, according to a study from the University of Louisville SRP Center. High blood pressure can contribute to heart disease, and both are more prevalent among Black adults in the U.S. than among any other race or ethnic group in the world. This is the first study to shed light on the potential underlying environmental exposures that might contribute to such health disparities.
