Electron microscopic measurements of the concentrations of airborne asbestos were carried out inside and outside an office building having ceilings sprayed with a crocidolite-containing material and floors covered with vinyl-chrysotile tiles. Under normal conditions in this building, constructed 10 years ago, the two asbestos-containing materials released fibers into the air. This is the first measurement of elevated (up to 170 nanograms per cubic meter) concentrations of indoor airborne asbestos associated with the weathering of asbestos floor tiles during their service life. Asbestos flooring is used in a large number of buildings and represents the third largest use of asbestos fibers in the United States and in Europe, ranking after roofing and asbestos-cement pipe.
对一座办公楼内外空气中石棉浓度进行了电子显微镜测量。该办公楼天花板喷涂了含青石棉材料，地板铺设了乙烯基温石棉瓷砖。在这座10年前建造的建筑正常使用条件下，这两种含石棉材料向空气中释放纤维。这是首次测量到与石棉地板砖在使用寿命期间风化相关的室内空气中石棉浓度升高（高达每立方米170纳克）。石棉地板在大量建筑中使用，在美国和欧洲，其石棉纤维用量排名第三，仅次于屋顶材料和石棉水泥管。
