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.

Pollen and mold counting has concluded for 2019 and will resume in February 2020.
