The purpose of this study is to evaluate analytical method for the measurement of carbonyl compounds and to apply method to the measurement of indoor and outdoor concentrations of these compounds at public facilities. For sampling, 2.4-dinitrophenylhydrazine (DNPH) coated DNPH-Silica cartridges were uwed in this study. DNPH reacts with carbonyl compounds and forms carbonyl hydrazone, The carbonyl hydarzone was eluted from the cartridge with acetonitrile and analyzed by reverse-phase HPLC with UV detection. Possible interference caused by ozone during sampling was eliminated by using KI trap commected in series with the DNPH-Silica cartridge. A number of experimental studies were undertaken to evaluate and validate the analytical method, including collection efficiency, recovery, repeatability, lower limits of detection, and effect of ozone. Indoor and outdoor measurements of carbonyl compounds were simultaneously carried out at 14 public facilities located in Taegu city and Kyungsan city from June to July, 1995. Except for one or two sites, the indoor concentrations were found to be higher than the outdoor concentrations for carbonyl compounds. And the concentrations of carbonyl compounds measured in the morning and afternoon were showed higher than the concentrations measured in the evening.
