DAQ Keeps You Up-To-Date on Pollen and Mold Counts in Delaware


Air Quality Monitoring Mold Spores & Pollen Graphic

Every year during allergy season (March 1 - October 31) the Division of Air Quality (DAQ) collects and reports pollen and mold counts three days a week. The report includes a color-coded rating chart that shows the level of hay fever and asthma symptoms that may be related to pollen exposures.

How's it done?
The mold and pollen sample collector is located on the roof of the DAQ offices at Grantham Lane, just south of the City of New Castle. Samples are collected on Sunday, Tuesday and Thursday. Then, on Monday, Wednesday and Friday mornings, a laboratory technician with DAQ goes onto the roof of the building, collects the sample, takes it back to the DAQ Lab, and determines the count by looking through a microscope.

Once the count is completed, the lab technician posts the information in two places:

The National Allergy Bureau (NAB) is the section of the American Academy of Allergy, Asthma and Immunology’s Aeroallergen Network that is responsible for reporting current pollen and mold spore levels to the public.
