| Abstract: | Although the perception of odorous contaminants cannot be precisely described, certain basic facts about human olfaction are known. With known facts or principles, it is possible to investigate odorous contaminants for air pollution control purposes. Odor remains, however, a very intangible commodity. Odorous contaminant investigations must be tailored to the individual problem or locality. Consequently, methods herein described were designed for individuals who have a working knowledge of either odor or air pollution problems. Background references are available for workers who are not familiar with either field.1-8 This method will describe generalized facts concerning odors as well as subjective and objective methods for measuring odorous contaminants in the field. The use of specific portions of the method depends upon each individual investigation. |
