Investigation of Asbestos and MMMF Containing Construction Material in Korean Buildings
Received 6 September 2004, accepted 13 January 2005
Abstract
140 buildings of Korean major cities were investigated for the presence of asbestos and man mademineral fibers (MMMF) in their construction materials. 73 (52%) and 84 (60%) buildings contained asbestosand MMMF in their construction materials, respectively, and 17 (12%) buildings contained both asbestos andMMMF. 75% of the asbestos containing buildings were mostly constructed during 1970's. 100% ofunderground shopping arcades, 90% of manufacturing workplaces, 84% of train and bus terminals had theasbestos containing construction materials. The manufacturing workplaces of Daejeon (89%) and Daegu(89%), which mostly had been built in the past, used asbestos containing building materials, while thebuilding in Seoul, Busan and Jinju, which were constructed recently, used relatively lower asbestos containingbuilding materials with 46%, 28%, and 33%, respectively. 9 building materials that have been widely used inKorea were analyzed using a transmission electron microscope equipped with energy dispersive X-rayanalyzer (TEM-EDX) for their mineral contents. All asbestos fibers showed typical characteristics ofchrysotile fibers with hollow tube structure. The average diameter ranged from 0.03㎛ to 0.05㎛, and theaverage length were ranged from 7.5㎛ to 12.0㎛. Atomic percentages of asbestos fibers were 51.9∼55.9%of Mg, 41.3∼44.3% for Si, and 2.7∼4.8% for Fe.
