This study indicates that infrared spectroscopy can be a useful analytical tool in the analysis of the decomposition of gases of sanitary landfills. The presence of NH3 gas or N2O gas, depending on the condition of the soil, would be difficult to ascertain quickly by other conventional means and with such simple sampling procedures. Further, simultaneous qualitative and quantitative analysis may be performed on a sample. The availability of commercial portable gas analyzers permits on site analysis for the decomposition gases of sanitary landfills.
