ST. PETERSBURG, Fla. (AP) - Pollen: It's on your car, in the air and especially in your sinuses.
From Florida to Texas to Colorado, 2010 is shaping up to be a monster of an allergy season. The words "pollen" and "allergy" are among the top 10 trending topics on Twitter in several U.S. cities.
Everywhere, it seems, is covered in a fine yellow dust that irritates our lives.
Oak trees are the culprit in many places in the southeast.
The trees produce 3,000 to 6,000 pollen particles per cubic meter; it only takes 10 particles to trigger an allergic reaction.
