Daniel Elliott, Ph.D., a senior consultant and an environmental engineer for Geosyntec based in New Jersey, will present an invited lecture on nanoremediation this week in Vienna, Austria.
The lecture, "Differential Reactivity of nZVI Towards Lindane — Implications for QA/QC and Field Scale Use," is part of the 2nd Annual Meeting of the NanoRem Consortium, being held April 7-9, 2014, at the University of Vienna.
Dr. Elliott, a member of NanoRem's Project Advisory Group, was invited to present the lecture by his colleague Thilo Hofmann, Ph.D., of the University of Vienna. Both are members of NanoRem, an international consortium comprised of university, national laboratory, and industry partners investigating the application and implications of environmental nanotechnology solutions for impaired properties in the European Union. Dr. Hofmann, a professor and dean in the University of Vienna's Department of Environmental Geosciences, is the principal investigator for NanoRem's Work Package 4, which focuses on the fate and transport of engineered nanoparticles in the environment.
Nanoremediation refers to the use of various materials at the nano-scale used to improve or enhance a contaminated site in such a way as to prevent, minimize, or mitigate damage to human health or the environment.
For NanoRem, these materials include surface-modified, nanoscale zero-valent iron (nZVI), carboiron, and various nanoscale iron oxides which, by virtue of their particle size (on the order of 100 nm or less), offer significantly enhanced reactivity and potentially improved selectivity for recalcitrant contaminant classes, including chlorinated solvents, pesticides, and redox-amenable metals.
Dr. Elliott's lecture will begin with an overview of the Love Canal Superfund project in New York, where lindane — and the benzene hexachlorides as a class — was among the most prevalent contaminants. He will then discuss how nZVI technology is well suited to treat recalcitrant organohalides such as lindane as well as nZVI's role in NanoRem activities.
Together with nZVI pioneer Wei-xian Zhang, Ph.D., Dr. Elliott played a key role in the development and applications of nZVI technology and has been involved in numerous bench-scale and field-scale applications since the late 1990s.
