Is pollen considered an air pollutant?

Pollen from grasses, trees, and weeds is the wonderful substance that allow plants to reproduce, but it is also responsible for numerous allergic reactions people experience. Although pollen is found naturally in the air, human activities and choices can increase the amount of pollen in our air, and in turn, can cause people to have more severe allergic reactions. Because human activities can increase the amount of pollen in our air and cause adverse health affects, some people view pollen as an air pollutant.

People commonly treat their allergies by avoiding situations where they might have an attack, by using dehumidifiers and air filters, or by taking medication. But, by becoming familiar with the source of you allergies, you can also begin to make choices that can prevent the severity of your attacks. The number of pollen particles in the air can be measured by performing a "pollen count". Pollen counts tell you the number of pollen grains per cubic meter of air. They can also tell you which tree, grass, or plant the pollen came from. Different plants and trees produce different amounts of pollen and knowing which plants are the largest contributors to your allergies can influence what flowers and trees you and your community chose to plant.
