✦ Synopsis

The particulate6 are collected on Whatman 41 cellulose filters and decomposed with sulfuric acid and hydrogen peroxide; bismuth is then measured by hydride generation/atomic absorption spectrometry. The detection limit is 0.08 ng m" if 500 m' of air is filtered through an 11-cm filter. Generally, the precision is better than 10%. The concentrations found in Ghent, Belgium varied between 0.1 and 0.8 ng mJ. Bismuth was also determined in NBS Orchard Leaves (SRM 1571); a value of 98.5 * 15 ng g-' was found.
