A considerable number of settled dust analyses for asbestos using TEM have been performed following the microvac sampling procedure. Some data also exist for analyses of carpet using the bulk carpet sonication technique. The values of asbestos in the dust have been usually given in terms of asbestos structures per square foot (s/ft2) or asbestos structures per square centimeter (s/cm2). To change from structures per ft2 to per cm2, divide the s/ft2 by 929.
