DOAS (Differential Optical Absorbance Spectrometry) has been designated as one of the instrumental analyses for the continuous and real time measurement of ammonia and styrene under the newly established Korean Offensive Odor Prevention Law. However, cases of odor monitoring using DOAS are very limited, as questions have been raised relating to its reliability, mainly for ambient monitoring. This paper primarily focused on the advantages and limitations of DOAS for the measurements of ammonia and styrene, with a review of the theoretical and field intercomparison studies, to address its suitability, particularly for odor monitoring purposes. However, this instrumental technique was found to be useful for real time continuous measurements of concentrations over a few ppbv, for both ammonia and styrene, and was also found to be sensitive enough for odor monitoring purposes over vast multi industrial complex regions.
