Studies on Determination of Trace Amounts of Airborne Asbestos

Collection, identification and data analyzing techniques are presented for airborne asbestos fibers.The limitations of thetechniques on the membrane filter method, X-ray diffraction method and infrared analysis are discussed. It was shown that any methods had some merits and demerits, and the most suitable technique shoud be adopted according to the concentration of asbestos fibre in ambient air
