Description

<p>Asbestos such as chrysotile, crocidolite (riebeckite asbestos), and amosite (grunerite asbestos) in building materials have been analyzed using microscopic and/or X-ray diffractometric methods. Fibrous asbestos particles in air and building materials have often been observed and counted using optical microscope and scanning or transmission electron microscope. Using electron microscopic analyses, trace asbestos around 0.1 mass% can be easily detected because of higher spatial resolution; however, these microscopic analyses are unsuitable for obtaining mass concentration. Asbestos in building materials have been measured using substrate standard correction/X-ray diffractometric analysis based on JIS A 1481 with acid treatment for dissolving matrix components; the trace asbestos might be determined. On the other hand, asbestos in pulverized building materials can directly be determined using conventional powder X-ray diffractometric analysis without chemical treatments. We reviewed microscopic and X-ray diffractometric methods concerned with quantitative analyses of asbestos.</p>
