Abstract

Objectives: Acetone/triacetine method for clearing cellulose ester membrane (CEM) filter has been a popular method for air-borne asbestos analysis. However, as a weakness of this method, it is time consuming to analyses asbestos samples after sampling. Crystalclear method can be used to analyses asbestos samples promptly after sampling. Although a strength of crystal clear method exists, there was little valid studied for the method. This study was conducted to compare acetone/triacetine method with crystalclear one for analysing asbestos sample. Methods: Test samples made in three different concentration ranges(low, medium and high concentration) were analysed by phase contrast microscopy after acetone/triacetine and crystalclear method treatment respectively. Results: We did not find statistical difference in analysed results between two methods, which were conducted in three different concentrations ranges. Conclusions: We concluded that crystalclear method can be used as clearing method for air-borne asbestos analysis instead of acetone/triacetine method.
