Air quality data for Cleveland, Ohio, for the period of 1967 to 1971 have been collated and subjected to statistical analysis. Total suspended particulate is clearly lognormally distributed, while sulfur dioxide and nitrogen dioxide are reasonably approximated by lognormal distributions. Only sulfur dioxide, in some residential neighborhoods, meets Ohio air quality standards. Air quality has definitely improved in the industrial valley, while in the rest of the city, only sulfur dioxide has shown consistent improvement. A pollution index is introduced which displays directly the degree to which the environmental air conforms to mandated standards.
