Plants were selected for industries subject to hazardous air pollutants (HAPs) fugitive emissions reduction, and the concentrations of 33 types of specific air pollutants were measured at stacks equipped with prevention facilities. The dominant HAPs emitted from the plant were identified, and air emissions were calculated based on the measurement information. In addition, carcinogenic and non-carcinogenic toxicity information was applied as weight to air emissions to identify important substances subject to management. These results were compared with air emissions information of pollutant release and transfer registers (PRTR). 30 types of specific air pollutants were detected in 77 stacks at a total of 35 plants. It was confirmed that only information on 25 types of specific air pollutants is provided for air emissions from PRTR in the same industry. In particular, in this study, information on the emissions of hydrogen cyanide and propylene oxide, which have the highest concentration and the largest amount of air emissions, are not included in the PRTR of the relevant industry, so there may be omissions regarding HAPs in terms of air emissions data. It was confirmed that there was a change in priority when the emission ranking calculated in this study reflected toxicity information. Potential carcinogenic substances are hydrazine, ethylene oxide, Be, Cd, acrylonitrile, and Ni, and non-carcinogenic substances are benzo[a]pyrene, Cd, hydrogen cyanide, and Be, Ni, hydrazine, and Pb were evaluated as important emissions in that order. It is believed that if more measurement data is supplemented in the future, it will be possible to more rationally select priority management target substances at plants emitting HAPs.
