Characterization of Airborne Particle Release from Nanotechnology-enabled Clothing Products.

ABSTRACT: This study investigated airborne particle release from seventeen nanotechnology-enabled clothing items, including eleven items that were advertised as containing silver nanoparticles. Clothing wear was simulated using an abrader, where the rotating clothing samples came in contact with felt abrader wheels, and size distribution and concentration of the released particles were measured using a Scanning Mobility Particle Sizer and Aerodynamic Particle Sizer. Through the use of inductively coupled plasma mass spectrometry, silver was detected in all eleven products advertised as containing silver, and its concentration varied from approximately 1 ppm to ~1.5×10⁵ ppm depending on the product. Nano-sized particles, as well as larger agglomerates, were released from all investigated p
