The concentrations of major volatile organic compounds (VOCs) were measured using a passive sampler in the leather industries, Shihwa and Banwol industrial complex. The leather industries were classified into four groups in raw materials and main product. The concentrations of total VOCs measured in process for ${ulcorner}$ manufacture of reconstituted leather and special treated leather${lrcorner}$was highest. The main VOCs measured in the leather industries was found to be toluene with a average concentration of 1,200 ppb. The major group selected in the leather industries was divided into three groups by the fingerprint analysis and the principal component analysis. The major VOCs in the groups classified by fingerprint analysis were found to be dependent on the characteristics of raw materials and main products.
