초록
Over the last 10 years, about 200 chemical accidents have occurred. The frequency of chemical leak accidentshas particularly increased since the 2012 accident of hydrogen fluoride gas leakage. When a chemicalaccident happens, the released gas-phase substances are more likely diffused into the air, which subsequentlymight cause serious damage to the health of local residents and the environment. To make a quick responseto such a chemical accident, it is significantly important to promptly analyze the accident-causing substances. In this study, a cross analysis was performed using PTR-TOF-MS and GC-MS to identify accident-inducingsubstances generated in the reaction process with brominated epoxy resin and acrylic acid. As a result of thetwo analyses, acrylic acid was not found to induce a chemical accident, whereas aromatic hydrocarbons and2-bromophenol were both identified as accident-causing substances. Given that rapid analysis is essential fora prompt response to chemical accidents, the cross analysis using two or more techniques may be useful toquickly identify accident-causing substances.
