Odor managements were divided from air pollution prevention law because of sensory, temporary, partial, and distributive characteristics. Therefore, odor prevention law and odor analysis method were published for malodor management in Feb. 2004, and Feb. 2005, respectively. In this study, we considered problems of odor prevention law and odor analysis method according to their enforcement, and then we suggested an alternative idea. In the odor prevention law, we thought over odor emission point, application of emission standard, and requirement of odor analysis organization. And also, we considered odor analysis methods such as sampling time, judgment procedure of dilution ratio values of the threshold limit for complex odor, field blank for aldehydes analysis, display of valid figure.
