Pollen and Mold

Pollen Counting imageDuring the business week, the Southwest Ohio Air Quality Agency measures the 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 business day at 10:00 a.m. with pollen and mold counts of the previous 24-hour period.

Counts will end for the season on November 25, 2015 and will resume in February of 2016.
