摘要: Abstract The emission concentrations of several chlorofluorocarbons (CFCs) were measured from a municipal waste treatment facility (located in Seoul, Republic Korea) to investigate the characteristics CFCs urban environment. To this end, total five (CFC-10, CFC-11, CFC-20, CFC-30, and CFC-113) analyzed by thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) method. results study indicate that formation CFC-11 (8.21 ± 1.68 ppb spring) CFC-20 (3.92 ± 3.93 ppb proceeded very actively within facility. Moreover, CFC-113 was also found relatively high (3.34 ± 1.31 ppb Unlike other CFCs, CFC-10 observed mainly at ambient (and reference) locations one point inside In conclusion, emissions some important are prominent process, as they either frequently or abundantly both winter spring. It is further indicated certain (like CFC-30) subject highly significant seasonal variations.
