This study was conducted to investigate the composition, detection rate, and exposure concentration of the airborne organic solvents from the working environmental measurements of total 4181 different type of workplace in 3280 workshops in which organic solvents are used. The results are as follows : 1. For all workplaces except washing, the detection rate of toluene and benzene were 80% and 20%, respectively. 2. The number of detection of aromatic hydrocarbon and ketone were ranged 1.41-2.39 and 0.62-0.90 per a sample in all workplaces except that showed 1.01 in washing. 3. The mean of detection frequency was $3.3{pm}2.5$ in all workplaces and there was no significant difference among that of each workplaces. 4. The airborne concentrations of methyl methacrylate, ethyl alcohol, methyl alcohol, and ethyl ether were $43.5{pm}47.0{;}ppm,{;}22.5{pm}51.0{;},{;}19.8{pm}57.6{;}ppm,{;}19.8{pm}40.14{;}ppm, respectively. And those of cellosolve, methyl cellosolve acetate, and N,N-dimethyl formamide were $4.1{pm}4.5$ ppm, $4.0{pm}18.5{;}ppm$, and $5.6{pm}7.7{;}ppm$, respectively and exceeded the occupational exposure limits enforced by Ministry of Labor in Korea. As the above results, it is suggested that the components of organic solvents should be indentified to efficient management, of working environment and conducted the engineering control for the workplaces using the hazardous materials.
