고상호,임태숙 한국환경분석학회 2019 환경분석과 독성보건 Vol.22 No.4
In this study, methods of extraction, purification, and instrumental analysis are validated for 16 types of polycyclic aromatic hydrocarbons (PAHs) defined by the United States Environmental Protection Agency (US EPA), to analyze their occurrence during cooking in residential environments. Accelerated solvent extraction (ASE), which is more efficient than other extraction methods, are used and the recovery rate of gaseous samples (excluding NaP) and particulate samples was 80-110% with a relative standard deviation (RSD) of 0.6-19.8%. The purification method was compared with the column and the cartridge purification, with recovery rates of 80-110% and 60-100%, respectively. Through this process, a high recovery rate of the 16 substances was confirmed by the column purification method after ASE. The rate was 78-102% (RSD: 0.3-10%) for the gas samples and 73.7-101.7% (RSD: 0.7-20%) for particulate samples, respectively. The recovery rate of the analytical method used in this study was 66.6-80.2% (RSD: 4.7-8.3%) in the gas phase samples and 72.5-97% (RSD: 5.1-10.1%) in the particulate samples. As a result, it seems reasonable to apply the analytical method proposed in this study to real sample analyses.
