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. And, ASTM rule risk assessment showed that all materials were "Q&M program" grade.

본 연구의 목적인 우리나라 일부 학교의 석면함유 건축자재을 조사하고 EPA AHERA rule과 ASTM rule을 적용하여 위해성평가를 실시하였다. 총 100개 학교를 2010년 1월부터 12월까지 조사하였다. 건축년도에 따른 ACM 검출율은 1980년대 이전 건축물은 100%, 1990년대 이전은 94.1%, 2000년대 이전은 100%, 2000대 이후는 62.5%로 나타났다. 학교별 ACM 검출율은 유치원과 고등학교는 100%, 초등학교는 97.1%, 중학교는 92.9%, 특수학교는 80%로 나타났다. 천장 텍스는 2~8 %의 백석면과 갈석면, 밤라이트 보드는 6~11 %의 백석면이 검출되었다. 또한 개스킷과 슬레이트 지붕은 각각 16~17 %, 10~13 %의 백석면이 검출되었다. EPA AHERA rule을 이용하여 ACM의 위해성 평가를 실시한 결과, 모든 건축자재는 "Pool" 등급이 나왔으며, ASTM rule 평가에서는 모든 ACM이 "Q&M program"이 필요한 것으로 나타났다.
