Presentation Overview:

The NIEHS Superfund Basic Research Program (SBRP), in collaboration with the Environmental Protection Agency (EPA), presents "Nanoparticles and Ecotoxicology." Dr. Stephen Klaine, Clemson University, will briefly overview some of the major considerations involved in assessing ecotoxicology and the challenges associated with predicting the effects of nanoparticles in aquatic ecosystems. His talk will focus on recent work involving multi-walled carbon nanotubes (MWNTs) interactions with natural organic matter (NOM) in studies using water fleas (Daphnia magna). Dr. Patrick Larkin, Santa Fe Community College, will discuss the use of a standard EPA-approved ecotoxicology test using daphnia with assays using a newly developed, 2000-gene DNA array for the fathead minnow to measure the potential toxicity of a reactive nano-iron particle. This is the eighth seminar in the Risk-e-Learning Series "Nanotechnology - Applications and Implications for Superfund." Previous seminars aired on CLU-IN January 18, 2007, February 13, 2007, March 15, 2007, April 19, 2007, May 31, 2007, August 16, 2007 & September 12, 2007; audio recordings are available through the CLU-IN archives. Please note the final session in this series will be "Nanotechnology: Looking Ahead," on November 8, 2007.
