Abstract

Street dust samples were taken between July and December 2005 at 25 locations in Shanghai, Beijing, and Hong Kong and sieved to 63 μm particle size before elemental analyses by CHN analyzer, XRF and ICP-MS. About 60% of the particles from the Beijing and Shanghai sieved samples were 52Cr and 53Cr by ICP-DRC-MS after a modified three-stage microwave-assisted acid digestion, are higher than those reported elsewhere. © 2008 American Chemical Society.
