Superfund Research Program
Research Briefs By Year: 2010
- 181 - Enhanced Detection of Toxic Substances with Phage Library-Enhanced Immunoassays -- Gee, Hammock
Release Date: 01/05/2010
U.S. researchers partner with scientists in Uruguay to develop super-sensitive immunoassays, enhancing the ability to detect contaminants in the environment and in exposed individuals.
- 182 - Can Phytoremediation Work for PCBs? -- Schnoor
Release Date: 02/03/2010
A study offers the first evidence that whole plants can take up and metabolize polychlorinated biphenyls (PCBs), suggesting plants could be used to help clean up PCB-contaminated sites.
- 183 - Sequestration of Dioxin by Clays -- Boyd
Release Date: 03/03/2010
Although the organic matter in soil is often considered best for sequestering contaminants, new evidence shows that clay is as good--and perhaps better--at sequestering dioxins.
- 184 - Linking Site Specific Contaminant Mixtures to Biological Responses -- Anderson
Release Date: 04/05/2010
New tools could help Superfund site managers evaluate the nuances of chemical mixtures and identify the most pressing threats to ecosystem and human health.
- 185 - Childhood Exposures to Pesticides May Contribute to Obesity and Diabetes in Adults -- Slotkin
Release Date: 05/05/2010
Organophosphates represent nearly 50 percent of worldwide insecticide use. Unfortunately, they may also contribute to another statistic: the increased incidence of obesity and diabetes.
- 186 - DEMET - Converting Waste into a Resource -- James
Release Date: 06/03/2010
In a prime example of turning lemons into lemonade, scientists have developed a method for reducing the ecological and health threats from abandoned mines by extracting and selling-at a profit-the residual metals that would otherwise seep from the mine sites into rivers and streams.
- 187 - Chronic Arsenic Exposure Linked to Increased Mortality Rate -- Ahsan, Graziano
Release Date: 07/07/2010
A unique study involving nearly 12,000 participants offers strong evidence of an increased risk of death among those who drink water from sources with elevated arsenic levels.
- 188 - TCDD May Contribute to Immune System Instability -- Kaminski
Release Date: 08/04/2010 A new computational model shows how the environmental contaminant TCDD causes immune system mayhem by interfering with the activation of crucial B cells.
- 189 - Use of Spatial and Temporal Analyses to Provide Insights into the Environmental Etiology of Cancer -- Aschengrau, Webster
Release Date: 09/01/2010
Scientists are investigating what individuals in geographic "hot spots" for cancer have in common to reveal possible routes of exposure to environmental carcinogens.
- 190 - Determining Susceptibility to Environmentally-induced Neurotoxicity -- Furlong
Release Date: 10/05/2010
Researchers use an innovative approach to track the health effects of organophosphate insecticides. The findings may also have implications for research on Parkinson's disease and studies on the health effects of nerve agents and aircraft engine fumes.
- 191 - Portable Biosensing Systems -- Daunert
Release Date: 11/03/2010
A team of scientists deploys bacterial detectors that light up in the presence of contaminants such as arsenic and zinc. In spore form, the bacteria can survive extreme conditions and be resurrected in minutes.
- 192 - Discovery of the Key to Metal Accumulation in Plants -- Schroeder
Release Date: 12/01/2010
Plants that take up hazardous metals can help clean up polluted soils, but they also can become a route of human exposure when edible crops take up pollutants. Researchers are deciphering how plants take up metals in order to better control the process.
