An evaluation of sampling, sample preparation, and analysis techniques for asbestos in settled dust in commercial and residential environments
The presence of asbestos in settled dust indicates that asbestos has historically been present in the localized atmosphere as airborne particles, and the possibility exists that this asbestos could be re-entrained in the air by future disturbances and activities. Therefore, capable methods for sampling and analyzing settled dust would be beneficial to document past (and potentially ongoing) episodes of asbestos contamination and to predict potential problems presented by asbestos-containing dust. In order to evaluate sampling techniques and to evaluate asbestos disperson in a variety of environments, three study sites were chosen. The first was a tire-brake repair shop, which would be expected to generate airborne asbestos because of the longtime use of asbestos in brake linings and the common practice of using jets of compressed air to remove accumulated dust from brake assemblies. The other two study sites were residences. The first residence, denoted Residence One, contains a known source of asbestos fibers, and the second residence, denoted Residence Two, contains no known asbestos fiber sources.
