Abstract

Ambient concentrations of halogenated compounds have been analyzed every two hours using the "Medusa" cryogenic pre-concentration system with gas chromatograph and mass selective detector (GC-MSD) at Gosan (Jeju Island, Korea) from Nov. 2007. Our analysis results identified country based emission ratios and correlation patterns among measured species. The emissions of these compounds in East Asia estimated by interspecies correlation method account for over ~30% of global emissions, and emphasize the importance of atmospheric measurement in this region.
