토양과 공기 중 석면함량의 상관분석을 위한 현장시험장치 개발 및 적용

초록

The objective of this study is to analyze the correlation of asbestos contents in soil with in air using field trial device in field scale experiment. Various wind velocities, 8 m/s, 11 m/s, 15 m/s and 18 m/s, respectively, were applied to evaluate releasable characteristics of the field trial device. Collected soil samples were analyzed by polarized light microscopy and SEM-EDS. Each air sample was examined by phase contrast microscopy. As a result, the field trial device was operable and its use was with ease. The correlation of asbestos contents in air with wind velocities represented positive, while the correlation of soil humidity with in air showed negative. In the case of 3∼6% asbestos contents in soil, it exceeded the acceptable risk range for exposure depending on soil humidity and wind velocity. It is suggested that remediation priority should be given to the site of >3% asbestos contents in soil.
