- 265 - The Genetics Behind the Killifish’s Adaptation to Pollution -- Hahn
Release Date: 01/04/2017
Killifish living in four polluted East Coast estuaries have adapted quickly to survive high levels of toxic industrial pollutants. In a new study, researchers explored the complex genetics involved in the Atlantic killifish’s resilience, bringing us one step closer to understanding how they rapidly evolved to tolerate normally lethal levels of environmental contaminants. Exploring the evolutionary basis for these genetic changes may provide new information about the mechanisms of environmental chemical toxicity in both animals and humans.
- 260 - Identifying Mechanisms for Regulating Gas Exchange in Plants -- Schroeder
Release Date: 08/03/2016
Superfund Research Program (SRP) researchers at the University of California, San Diego (UCSD) are identifying important mechanisms that plants use to respond to changes in the environment. They recently discovered molecular mechanisms that enhance the activity of proteins essential to closing stomata, or pores found on the surface of leaves, in response to environmental stressors.
- 224 - Effects of Cadmium and Copper on the Fish Olfactory System -- Gallagher
Release Date: 08/07/2013
A series of studies from a research group led by University of Washington (UW) grantee Evan Gallagher, Ph.D., provide insight into the mechanisms underlying injury to the olfactory system of fish exposed to cadmium (Cd) and copper (Cu) including concentrations seen in the environment.
- 195 - Mechanism of Resistance to PCB Toxicity in Fish -- Wirgin, Hahn
Release Date: 03/02/2011
A 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.
- 194 - Sediment Caps That Degrade Contaminants -- Reible
Release Date: 02/02/2011
Some 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.
- 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.
- 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.
- 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.
