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. The drum slowly rotates one turn over the course of seven days while collecting particles. The tape is removed after one week, cut into day-length sections, and these sections are mounted on a microscope slide with fuchsine -stained gelatine. The fuchsine selectively stains plant material magenta, making the pollen easy to differentiate from bycatch when analysed under a light microscope.

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. Atmospheric particulate matter PM are microscopic solid or liquid matter suspended in the air.

Spring means flower buds and blooming trees — and if you're one of the millions of people who have seasonal allergies, it also means sneezing, congestion, a runny nose and other bothersome symptoms. Seasonal allergies — also called hay fever and allergic rhinitis — can make you miserable. But before you settle for plastic flowers and artificial turf, try these simple strategies to keep seasonal allergies under control. Seasonal allergy signs and symptoms can flare up when there's a lot of pollen in the air. These steps can help you reduce your exposure:. There's no miracle product that can eliminate all allergens from the air in your home, but these suggestions may help:. Rinsing your nasal passages with saline solution nasal irrigation is a quick, inexpensive and effective way to relieve nasal congestion. Rinsing directly flushes out mucus and allergens from your nose. Saline solutions can be purchased ready-made or as kits to add to water.
