pollen count, spring

Dr. Donald Dvorin counts spring pollen at The Asthma Center’s Philadelphia pollen counting station.

Spring pollen season is right around the corner! With warming temperatures, we are only a week or two away from the start of spring pollen, with the first pollen expected from juniper, cedar, maple and elm trees. At the moment, cold evenings are preventing most tree buds from opening and thus holding off the release of pollen. As the weather warms, we will see a surge in pollen as trees across the region start to bloom. Locations further south (e.g. Florida, Carolinas) have already reported high levels of pollen, and as the Philadelphia region warms, we expect to be the next in line.

Local Daily Pollen Counts

At The Asthma Center, we count the local pollen every day and provide that count to the community. We use a pollen counting device called a Burkard Spore Trap Device, which samples the air by trapping pollen and other airborne molecules on a greased slide. Every morning, we remove the slide and examine it under a microscope. Different plant pollens have unique shapes, so we can count how much of each plant pollen is on the slide and use that metric to determine the daily pollen count.

Philadelphia’s Only Certified Pollen/Mold Counting Station

The National Allergy Bureau is a nonprofit organization affiliated with the American Academy of Allergy, Asthma, and Immunology that oversees and certifies pollen/pollen counting stations across the US. The Asthma Center operates the only certified pollen/mold stations in the Delaware Valley, with one location in Philadelphia and the other in South Jersey-Mount Laurel, NJ.
