PRINCETON, NJ — Geosyntec Consultants is pleased to announce that Daniel Elliott, PhD, co-authored an article in the May 2009 issue of Journal of Environmental Engineering entitled "Degradation of Lindane by Zero-Valent Iron Nanoparticles." The Journal of Environmental Engineering is the magazine of the American Society of Civil Engineers.
In the article, Dan and his co-authors, Hsing-Lung Lien of the National University of Kaohsiung in Taiwan and Wei-Xian Zhang of Lehigh University, discuss promising results they have achieved using nanoscale zero valent iron (nZVI) to degrade lindane. Lindane was an organochlorine insecticide commonly used worldwide from the 1940s to 1990s and is classified as a "persistent organic pollutant" (POP). Many European countries are presently grappling with the public health challenge of dealing with unsecured and unlined dumps containing lindane and other POP pesticides, which pose a direct exposure risk to people and a threat to soil and groundwater. The authors' work shows that the nZVI technology has the capability to degrade recalcitrant contaminants like lindane far more quickly than biological remedies.
