Casuccio, G., R. Ogle, L. Wahl and R. Pauer, Worker and Environmental Assessment of Potential UNP Releases, Phase I Final Report: Data Collection, RJ Lee Group, Inc. and Lawrence Berkeley National Laboratory, 2009.
Nanotechnology and the use of unbound engineered nanoparticles (UNP) is a rapidly developing area of material science. Unbound engineered nanoparticles are defined as engineered nanoparticles that are not contained within a matrix that would prevent the nanoparticles from being mobile and a potential source of exposure. At this time there are no regulatory environmental release limits or worker exposure limits for unbound engineered nanoparticles. Some preliminary consensus standards have been issued, but they are still under development by various organizations.
In an effort to evaluate worker exposure and potential environmental release of unbound engineered nanoparticles at Lawrence Berkeley National Laboratory, a multi-phase pilot study was initiated in the summer of 20091,2. RJ Lee Group, Inc. was retained to assist in the design, setup, and implementation of the study. The goals of the pilot study are to comply with Department of Energy (DOE) Notice N456.1, The Safe Handling of Unbound Engineered Nanoparticles3 and meet the requirements of the DOE Nanoscale Science Research Centers Approach to Nanoscale ES&H4.
