Pollen and Mold

During the business week, the Southwest Ohio Air Quality Agency measures the daily levels of naturally occurring airborne pollutants: pollens and molds. These counts are expressed in spores per cubic meter of air for mold levels and grains per cubic meter of air for pollen levels. Residents can also call the Air Quality Pollen and Mold Hotline at 513-946-7753. The hotline is updated each day at 10:00 a.m. with pollen and mold counts of the previous 24-hour period.
