Pollen and Mold

During pollen and mold season, the Southwest Ohio Air Quality Agency measures the daily levels of naturally occurring airborne pollutants: pollens and molds. These counts are expressed in grains per cubic meter of air for pollen levels and spores per cubic meter of air for mold levels.
