ODOR THRESHOLD TABLE FOR CHEMICALS

This is a respiratory protection guide from 3M Corporation that contains a table of odor thresholds.  These start on page 15 of the enclosed PDF document.  An odor threshold is the lowest airborne concentration that can be detected by a population of individuals.  While odor thresholds can serve as useful warning properties, they must be used cautiously because olfactory perception varies among individuals.  Moreover, as the table indicates, some odor threshold concentrations are above their respective Occupational Exposure Limits.   For assistance in interpreting these data, contact your Division's Industrial Hygiene representative.
