摘要：An outline of odor measurement procedures and odor countermeasures is given. Basic aspects of the sense of smell are: (1) odor intensity, (2) odor character or quality, (3) hedonic tone, and (4) frequency. Odor concentration, which indicates number of dilutions until odorless, is usually used to quantify odor. Japan′s Offensive Odor Control Law provides for sensory testing and measurement of 22 odorous substances. The sensory test known as the Triangular Odor Bag Method is conducted by at least six panelists with normal smell function to measure concentration. The Law defines the Odor Index as ten times the common logarithm of odor concentration. There are two steps to prevent odor emission from industry. First, the cause of the odor is removed. Secondly, deodorant equipment is introduced. Duct work is also important.
