Superfund Research Program
- 193 - Accelerating Pump-and-Treat Remediation at Arsenic-contaminated Sites -- Chillrud, Stute, Mailloux
Release Date: 01/05/2011Pumping contaminated groundwater to the surface to filter out toxins is time-consuming and expensive. A new process makes this method more efficient by adding chemicals to stir up toxins while the water still underground.
- 194 - Sediment Caps That Degrade Contaminants -- Reible
Release Date: 02/02/2011Some Superfund sites may just need a little sizzle. Researchers find that using electricity can stimulate microbial growth and help break down contaminants in underwater sediments.
- 195 - Mechanism of Resistance to PCB Toxicity in Fish -- Wirgin, Hahn
Release Date: 03/02/2011A team unravels the mystery of how Atlantic tomcod living in waters contaminated with polychlorinated biphenyls (PCBs) not only survive in their polluted environment, but thrive.
- 196 - Nanoparticles Enhance Imaging of Intracellular Bioreduction of Chromate -- Irudayaraj
Release Date: 04/06/2011Researchers send tiny gold balls into bacterial cells on a mission to reveal how the cells process Chromium (VI). The bacteria's ability to transform this harmful metal to a less toxic form could make it an important ally in cleaning up Superfund sites.
- 197 - Poplars are Choosy about PCBs -- Schnoor
Release Date: 05/04/2011Could trees be the world's biggest vacuum cleaners? Scientists study how poplar trees help clean up some polychlorinated biphenyls (PCBs) and reduce the risk of human exposures.
- 198 - Chlorinated Contaminant Remediation - Dual Function Responsive Membranes -- Bhattacharyya
Release Date: 06/01/2011A promising new double-stacked filter inspired by membranes found in nature may help tackle trichloroethylene (TCE)the most common organic groundwater contaminant in the United States.
- 199 - Foray Into Tackling the Toxicity of Environmental Pesticide Mixtures -- Halden
Release Date: 07/06/2011Even before they are born, many babies are exposed to the pesticides chlordane and permethrin. New research offers the first demonstration of how these chemicals affect infants' fragile immune systems.
- 200 - Celebrating a Significant Milestone in Research Dissemination -- Avakian
Release Date: 08/03/2011Remember when email was cutting-edge? SRP's Research Briefs have been reaching readers around the globe since those early days. We celebrate the 200th brief with a look at how SRP's science communication has evolved over nearly 15 years.
- 201 - What a Difference a Methyl Group Makes -- Swenberg
Release Date: 09/07/2011Some proteins can turn genes on or off, like a light switch, by adding or removing a methyl group. Scientists are uncovering how these switches are wired, offering new insights for research on stem cells and cancer.
- 202 - Size-resolved Chemical Characterization of Atmospheric Aerosols -- Betterton
Release Date: 10/05/2011Some mining operations release dust containing hazardous elements like arsenic and lead into the air. Scientists have developed a new approach for detecting these airborne pollutants, assessing their potential health impacts and reducing human exposures.
- 203 - Research Shows Arsenic Attaches to Sediments, Protects Human Health -- van Geen
Release Date: 11/02/2011Scientists find arsenic can attach to sediments around deep wells, potentially reducing the risk of arsenic exposure for water users. The finding has implications for how arsenic-contaminated water sources are treated and managed.
- 204 - CALUX Generation 3 - Enhanced Sensitivity for Low Volume/Low Concentration Samples -- Denison
Release Date: 12/07/2011Firefly genes make the CALUX contaminant detection tool literally light up in the presence of dioxin and related chemicals. New advances make the tool 10- to 100 times more sensitive.
