About Pollen Levels

LOW: Pollen levels between 0 and 4.0 tend to affect very few individuals among the allergy-suffering public.

MEDIUM: Pollen levels between 4.1 and 8.0 will likely cause symptoms for many individuals who suffer from allergies to the predominant pollen types of the season.

HIGH: Pollen levels between 8.1 and 12.0 tend to affect most individuals who suffer from the pollen types of the season. Symptoms may become more severe during days with high pollen levels.

About Mold Levels

Absent:	0	These definitions are from the American Academy of Allergy Asthma & Immunology and allow comparison between sites across the country.They are based on ecological measurements, not health effects. However, assuming dose/response relationships are the same across the country, the definitions are probably more appropriate than a definition based on local numbers. This does mean that, for some stations, some categories will never be high.
Low:	1 - 6499
Moderate:	6500 - 12999
High:	13000 - 49999
Very High:	>50000

If the count falls within this category:	Allergy sufferers who are allergic to these pollens or molds may experience symptoms of hay fever or asthma.
Absent	No symptoms.
Low	Only individuals extremely sensitive to these pollens and molds will experience symptoms.
Moderate	Many individuals sensitive to these pollens and molds will experience symptoms.
High	Most individuals with any sensitivity to these pollens and molds will experience symptoms.
Very High	Almost all individuals with any sensitivity at all to these pollens and molds will experience symptoms. Extremely sensitive people could have severe symptoms.
