- Abstract
- Objectives: The purpose of this study is to analyze the number and influence factors of asbestos fibers in the air of farmhouses with asbestos cement slate roofing, as well as in rainwater per unit area of the asbestos cement slate roofing.
Methods: At a distance of 1 m from the end of asbestos cement slate roofing in 20 farmhouses, the asbestos fiber in the air was collected three times on a clear day downwind from the prevailing wind. Rainwater falling from the slate roofing was collected four times with a 1.05-m rainwater pipe on a rainy day at the 20 farmhouses, filtered with a MCE filter, and analyzed with a phase contrast microscope.
Results: The geometric mean of the number of asbestos fibers in the air of farmhouses with slate roofing was 0.11 fiber/L, and no samples exceeded the recommended standard of 10 fiber/L. As a result of multiple regression analysis, a factor which gave a significant influence to the asbestos fiber content in the air was the gross area of slate roofing at the target farmhouses. The number of asbestos fibers included in rainwater collected per 1 m2 of slate roofing was 1,753 fiber/L∙m2. As a result of multiple regression analysis, the number of asbestos fibers contained in rainwater per 1 m2 of slate showed a significantly higher tendency as the year of slate roofing installation at the target farmhouses receded.
Conclusions: It was confirmed for the first time in Korea that asbestos from asbestos cement slate roofing scatters into the air.
