| This document was prepared by Emily Keane, a National Network for Environmental Management Studies (NNEMS) grantee under a fellowship from the U.S. Environmental Protection Agency. The goal of this document is to provide information about the fate, transport, and toxicity associated with the use of nanoscale zero-valent iron (nZVI) for Superfund remediation. Specific and unique site conditions are likely to determine the usefulness and influence the fate and transport of nZVI particles during remediation efforts. Factors to consider prior to application include: effects of geochemistry on the mobility of nanoparticles, use of metal catalysts and coatings on the movement of nZVI particles and other variables affecting the fate and transport of nZVI in the environment. Other considerations include potential environmental and human health effects as a result of the fate and transport of nZVI in the environment. |
