Abstract
A study of exposures of metal machining shop workers to inhalable and total oil mist aerosols produced by metalworking fluids was conducted. The purpose of the study was to examine associations between total and inhalable oil mist exposures. The study group consisted of 23 workers employed in a metal machining factory where they used severely, refined nonaqueous (straight) cutting fluids while lathe cutting metal rod stock. Breathing zone samples were collected simultaneously using a 37 millimeter closed face cassette (37mm sampler) and an Institute of Occupational Medicine (IOM) aerosol sampler. The 37mm sampler collected total oil mist samples and the IOM sampler collected inhalable samples. The amounts of oil mist collected by the samplers were determined gravimetrically. Associations between the inhalable oil mist exposures (EIOM) and the total oil mist exposure (E37) were examined by logistic regression analysis. Values of the S-coefficient, defined as the ratio of the EIOM to the E37, were computed. The mean value of the S-coefficient for all 23 pairs of measurements was 2.96+/-0.60, which indicated that the inhalable oil mist exposures were significantly higher than those regarded as representing the total oil mist exposures. The authors conclude that the IOM sampler consistently collects more oil mist aerosol than the 37mm sampler. This finding is consistent with the results of studies conducted in other industrial environments.
