The emission characteristics of VOCs (volatile organic components) from industrial waste treatment facilities classified by Korea standard industry classification code (902) have been studied. The sampling was performed by using 3M OVM (organic vapor monitor) #3500 at 7 industrial waste treatment workplaces classified into 3 different kinds of 5 digits SICC (standard industry classification code) during from July to September 2004 in Sihwa Banwolindustry complex at Kyunggi province, Korea. The EPA 8020/8240 Aromatic Volatile Mix (10 chemicals, each 100μg/mL) was used as standard chemicals for quantitative analysis with a gas chromatography. Toluene was observed as a major emission component, with the concentration ranging from 0.5ppm to 14.0ppm. The order of emission concentration was toluene, styrene, ethylenebenzene and m,p-xylene. Another analyzed components, benzene, chlorobenzene, and dichlorobenzene, showed very low concentration compared to that of the toluene. The highest emission concentration was observed in SICC 90222 industry. The emission fingerprints of 3 different SICC showed different patterns according to their sampling sites and treatment characteristics.

The purpose of this study is to estimate the effect of sunlight on the measurement results of the tube type of NO2 passive sampler. Total 252 samples; seven duplicates, two sites with different concentration level, and nine days concerning to both exposure to sunlight and screened passive samplers with aluminium foil, were measured and analyzed. Relative standard deviation(%) of measurement data in this study was calculated as less than 10%, and it meant that even the simplest passive sampler showed comparatively high precision. The average concentration values of the screened passive samplers were turned out to be 22.4%∼25.5% higher than that of the passive samplers which were exposed to sunlight. Consequently, the sunlight was found to be the most important meteorological factor to affect the measurement for the tube type of passive samplers.
