what unit is pollen measured in
From Wikipedia, the free encyclopedia. Pollen count is the measurement of the number of grains of pollen in a cubic meter of air. The higher the number, the more people will suffer if they are allergic to a particular pollen (hay fever). Usually, the counts are announced for specific plants such as grass, ash, or olive.These are tailored to what is usually a common plant in the area being measured.ne method of taking the sample uses a silicone grease-covered rod that is rotated in the air to collect the pollen. The rod is rotated periodically during the collection period to gather samples through an entire 24-hour day.
