In this study, sampling and analysis was carried out for 13 compounds, in order to investigate the odorous compound emissions from landfill stacks and surrounding ambient air. These results revealed that concentration of hydrogen sulfide was $0.13{sim}0.66;ppb$ in the ambient air. Also, concentrations of hydrogen sulfide ($151{sim}358;ppm$) were the highest value in odorous sulfur compounds from landfill stacks. In case of VOC, toluene was obtained the highest out of volatile organic compounds. It was found that the concentrations of hydrogen sulfide near the landfill was higher than that inside city such as Seoul although it was located in a rural area. The result was due to the effect of hydrogen sulfide emitted from landfill stacks.
