Abstract
The objective of this study is to investigate the distribution of asbestos containing materials and to evaluate risk assessment method in some schools, Korea. For the survey on ACM risk assessment, we used both EPA AHERA rule and ASTM rule. We investigated 100 schools between January and December in 2010. Detection rate of the ACM according to construction year showed that before 1980's, 1990's, 2000's, after 2000's buildings were 100%, 94.1%, 100% and 62.5%, respectively. Compared with school types, detection rate of the ACM in Kindergarten, Elementary, Middle, High, Special Education schools were 100%, 97.1%, 92.9%, 100%, 80%, respectively. Ceiling textiles contained chrysolite/mixed amosite(2∼8 %) and wall cement flat boards contained chrysolite(6∼11 %). Also, gasket contained chrysolite(16∼17 %), slate roof contained chrysolite(10∼13 %). In this study, risk assessment EPA AHERA rule of ACM showed that all materials were Pool grade.
