자동차 정비업소에서의 석면섬유 및 총분진 농도

다국어 초록 (Multilingual Abstract)

We collected total 45 samples of asbestos fibers and total dust concentration by 2
personal sampling and 1 area sampling method from 5 auto repair shops in Asan city for 3
days. The results are as below. Asbestos fibers in the air of 30 samples from auto repair
shops by mixed cellulose esters (MCE) filters were  ×   fiber/cc. It is very low, so it
is not reach to the standard of permission of indoor air quality which is 0.01 fiber/cc. In 17
of 30 samples, asbestos was detected, but they are lower than quantitative limit. According
to sampling media, total dust concentration collected by MCE filters (140.3㎍/㎥) is
significantly higher than PVC filters (95.7㎍/㎥), but it is much lower than the occupational
exposure limit which is 1st class of dust (2,000㎍/㎥), and there is no difference on
number of repairing and number of exchange of brake lining. According to the result, the
concentration of asbestos fibers and total dust in auto repair shops are much lower than
standard of permission. They are lower than quantitative limit, so it is considered that
there are no brake linings or brake pads which have asbestos have been repaired.
