Superfund Research Program (SRP) researchers have provided a unique glimpse into the effects of the Deepwater Horizon oil spill on water in four Gulf Coast states. They measured levels of bioavailable polycyclic aromatic hydrocarbons (PAHs), a family of compounds found in oil that are toxic to humans and wildlife.

Superfund Research Program (SRP) studies published in late 2011 and early 2012 provide new evidence about arsenic. The studies reveal unexpected sources of arsenic exposure, demonstrate that adverse health effects are linked to low levels of exposure, show the mechanisms behind some of its health effects, and suggest a strategy for reducing exposure from well water.

Scientists at the University of California, Davis NIEHS Superfund Research Program have shown that newborns and infants may be more susceptible to harm from particulate matter than adults.

Exposure to low levels of arsenic in drinking water is linked to increases in blood pressure and increased risk of heart disease among adults. Now a study from the University of Arizona NIEHS Superfund Research Program links arsenic exposure during early development to heart problems.

A novel system developed by researchers at the Brown University NIEHS Superfund Research Program has been shown to effectively remove low concentrations of copper, nickel and cadmium simultaneously from a liquid solution, returning the contaminated water to federally accepted standards of cleanliness.

Amplification of aspects of the molecular mechanism of dioxin action has allowed the Denison research group to improve the sensitivity of detection of the CALUX cell bioassay system for detection and relative quantitation of dioxin and related chemicals by 10- to 100-fold.

This podcast discusses research that addresses a concern that the use of deep-water wells could cause arsenic-laden water from shallower aquifers to contaminate aquifers tapped by deeper wells.

To our knowledge, this is the first demonstration of size-resolved atmospheric aerosols associated with arsenic and lead in the vicinity of mining operations, information necessary for source apportionment and exposure assessment.

Researchers confirmed that Tet proteins regulate the conversion of cytosine to 5mC and three other methylated bases. Because methylation of cytosine has significant potential for altering gene activity, this discovery opens the door to a wide array of research and application opportunities.

This month, the Superfund Research Program (SRP) marks an important milestone - Research Brief 200.
