Summary:In order to determine the counts of asbestos fibers in alcoholic beverages and tap water, we investigated the suitability of various filters for the collection of asbestos fibers and the use of vacuum evaporation treatment to visualize the fibers by means of a scanning electron microscope (SEM) together with an energy dispersive X-ray microanalyzer (EDXMA). The use of a polycarbonate filter and pretreatment by carbon evaporation for SEM-EDXMA allowed asbestos fibers to be discriminated clearly from other fibrous materials. Using this SEM-EDXMA method, the chrysotile asbestos fiber counts in such beverages as sake, beer, wine and drinking water were measured. One sample of imported wine contained two bunches of chrysotile fibers. The chrysotile asbestos fiber counts in most beverages were at the trace or not detectable level.
