Pollen count

A pollen count is a measurement of the number of pollen grains in a given volume of air. Pollen counts, and forecasts of pollen conditions, are routinely produced and reported to the public because high aerial pollen concentration is associated with increased rates of allergic reaction for those with conditions such as hay fever and asthma. The pollen counted are usually identified to family ; particularly families with hyperallergenic pollen e. Thunderstorm asthma events as well as mild winters with warmer days lead to increases in pollen counts, [1] while colder winters lead to delayed pollen release. In the UK, the public announcement of the pollen count was popularised by Dr. William Frankland , an immunologist. The National Pollen and Aerobiology Research Unit became the world's first pollen forecasting service in According to a study by Leonard Bielory, M. One method for sampling pollen from the air is the Burkard trap, also known as the seven-day volumetric spore trap, [3] [4] which works by facing towards the wind and drawing in air using a pump. The pollen particles drawn in by the pump are then stuck to a silicone grease -coated tape that is attached to a rotating drum.

It is a number on a scale from 1 to , where a low value green colors means good air quality and a high value red colors means bad air quality. CAQI colour-coding is used in all air pollution forecast panels of the meteogram to indicate the level of pollution. For the pollen forecast there are no official guidelines for color-coding, as pollen are not part of the Air Quality Index forecast. Therefore, measurements along roads will show higher values than forecast here. The second panel shows the forecast of particles PM and desert dust for Spain.

Pollen is essential to the survival of the planet, but it can also be an extreme irritant to the more than 67 million Americans who suffer from pollen allergies. Just how irritating pollen is going to be on any given day is estimated by a pollen count which measures how much pollen is in the air. It is expressed in grains of pollen per cubic meter over a 24 hour period. We have embedded pollen count, mold count, and air quality index numbers in your local AllerVie clinic page. You can also access the pollen count from the American Academy of Allergy, Asthma, and Immunology website , as well as subscribe to notification emails every time the pollen count has been updated. Pollen and mold levels are determined by the National Allergy Bureau and have been translated into these four levels based on the counts for the majority of days and the averages over the years. A low pollen count means that only people who are extremely sensitive to pollen and mold will have allergy symptoms. A very high pollen count means that almost everyone who has an allergy to molds and pollen will experience symptoms.
