Abstract

This study investigated exposures to oil mist obtained from an cutting oil manufacture shop and 5 machining shops and also analysis of some oils. The results were that geometric average concentrations of oil mist were $0.29 mg/m^3$, which was less than current $TLV(5mg/m^3$) in Korea. The proper case of either type of system will ensure that atmospheric concentrations of oil mist in machine shops will be within the TLV. It should be remembered, however, that this TLV was established before there was any suggestion that in the inhalable of oil mist might rarely be carcinogenic, and so it seems prudent to keep atmospheric content as low as possible. The analysis of insoluble cutting oils with GC-MSD showed that considerable suspected PAHs were contained. But soluble cutting oil(KSM-W2) didn't almost contain PAHs.
