Title Factors affecting airborne concentrations of asbestos in a commercial building
Bibliographic information Sep. 1994, Vol.55, No.9, p.823-828. Illus. 26 ref.
Abstract The effect of renovation and return air-distribution systems on the exposure of occupants in a commercial building to asbestos under worst-case conditions was evaluated. General area samples were collected in four test and five control locations over five days. The presence or absence of construction or of a suspended ceiling acting as a return air plenum were tested for effect on airborne concentrations of asbestos. To maximize the likelihood of detecting measurable effects, all sampling was performed in areas with damaged asbestos containing surface material. Airborne concentrations of asbestos were consistently less than 0.008 structures per cubic centimeter (s/cm3), with only 15 of 60 samples having detectable levels. The highest concentrations were found in the construction area (0.007 s/cm3) and in the area with no suspended ceiling (0.008 s/cm3), though tests of statistical significance for these effects were equivocal.
