The purpose of this study was to assess the ambient level of Polynuclear aromatic hydrocarbons(PAHs), oil mist of the metalworking fluids(MWFs), especially in heat treat industry and non heat treat industry. And we assessed the relationship of the pattern of exposed PAHs with oil mist during survey day. The study population of heat treat industries contained 98 workers, non-heat treat industry contained 40 workers. Persona samples were taken for ambient monitoring of PAHs and oil mist. PAHs was to analyze the relationship of airborne oil mist. The geometric mean of airborne total PAHs was 3.44 ㎍/㎥ in heat treat industry and 0.13 ㎍/㎥ in non heat treat industry, Pyrene and Benzo(a)pyrene was detected from heat treat industry and Naphthalene in heat treat industry was significantly detected higher than in non heat treat industry. The geometric mean of airborne oil mist was 0.19 mg/㎥ in heat treat industry and 0.70 mg/m3 in non-heat treat industry. The correlation between oil mist and total PAHs was shown below, total PAHs in workers of non heat treat industry and heat treat industry were not significantly correlated with oil mist.
