The exposure level to various organic solvents for 330 workers in 7 domestic paint factories was evaluated by using a gas chromatograph. As a result of the investigation, twenty-five types of organic solvent were detected in the working environment. The most common organic solvent was toluene(97.0%), and followed by m-Xylene(68.2%), MIBK(59.7%), p-Xylene(52.15%), MEK(48.8%) and o-Xylene(46.1%). The mean concentration was the highest in methanol(18.236 ppm) and methyl ethyl ketone(10.565 ppm), 1.1.1-trichloroethane(8.952 ppm) and ethyl acetate(8.179 ppm). The concentration of toluene was 6.540 ppm.

The purpose of this work was to document the conditions regarding organic solvent exposure to the workers in paint industry. Air concentrations of organic solvents were measured by passive personal samplers and analyzed by a gas chromatography. Urine samples for hippuric test were also taken from 330 workers who have worked at seven domestic factories for more than two years. Amongst 25 organic elements detected in the indoor environment of working places, toluene was the most common element, and methanol showed the highest mean concentration(18.2ppm). A few elements including methylethyl ketone and toluene partially exceeded the Korean Permissible Exposure Limit. A lack of environmental facilities such as exhaust ventilation, automatic cleaning system, and personal safety devices at present work plaus brings about various occupational diseases.
