Environmental Chemistry of Metal Pollution in the U.S.-Mexico Border Region
The U.S.-Mexico Border is an area which historically has had a high level of mining and metal processing. Past practices have resulted in releases of heavy metals to the environment. Also a large number of mine tailings and abandoned mines continue to be a source of heavy metal releases. This session will evaluate the toxicological effects, transport and transformation of metals in the environment. Aditionally the session will examin technologies to remediate and recover metals as well as prevent releases.
