||Airborne monitoring to distinguish engineered nanomaterials from incidental particles for environmental health and safety
||Feb. 2009, Vol.6, No.2, p.73-81. Illus. 27 ref.
||This article compares two methods used to distinguish airborne engineered nanomaterials from other airborne particles in a facility that produces nano-structured lithium titanate metal oxide powder. The first method involved off-line analysis of filter samples collected with conventional respirable samplers at seven locations. The second method used two hand-held direct-reading instruments to measure total and respirable airborne particles. Findings of both methods were consistent in showing that airborne nanoparticles in this facility were dominated by "incidental" sources (e.g., welding or grinding), and that the airborne "engineered" product was predominately composed of particles larger than several hundred nanometres.
