Character

Another dimension of odor is its character, or what the odor smells like. ASTM publication DS 61 (Dravnieks 1985) presents character profiles for 180 chemicals using a 146 descriptor scale. The scale uses terms such as fishy, nutty, moldy, rancid, sewer, and ammonia. This dimension is useful in air pollution control for describing the source or process responsible for community odors because different odor characters are associated with various processes and industries. Table 5.26.1 provides a short list of the industrial odor character descriptions.
