A uniform air pollution index for the U.S. is proposed. The index was developed from ten criteria identified in a survey of all the air pollution indices currently in use in the U.S. and Canada. The proposed index, named the Pollutant Standards Index (PSI), was designed to overcome the objections that some air pollution control agencies have raised about existing indices. PSI is a segmented linear function based on the National Ambient Air Quality Standards and Federal Episode Criteria. It is a maximum type index, reporting only the highest numerical value of all the sub-index values for each pollutant.
