The toxicity of asbestos has been constantly an active research topic.Although asbestos has lots of advantages owing to its stable physicochemical properties and economic characteristics,nations enforce policies prohibiting or limiting its use because of its critical impact on human health.Especially in Korea 96% of imported asbestos are slate construction materials and with the influence of Saemaul movement,thatched roofs have been drastically replaced with slate roofs.Efforts to know the distribution characteristics of extensively used asbestos cement slates and to find out the removal method that suits the distribution characteristics are still in an insufficient state.The purpose of this work was to probe into the distribution of asbestos cement slate buildings in Korea and provide basic data of distribution characteristics for policy making in which consideration of the differences between rural and urban regions is necessary based on findings of the studies so far.It is considered helpful in many ways to solving asbestos cement slate related problems in countries where asbestos usage is increasing even after the 2000s including China.
