|If the count falls within this category:||Some people may experience an allergic reaction to the pollens and molds to the extent listed.|
|Low||Only individuals extremely sensitive to the pollens and molds will experience symptoms|
|Medium||Many individuals sensitive to these pollens and molds will experience problems|
|High||Most individuals with any sensitivity to these pollens and molds will experience symptoms|
|Very High||Almost all individuals with sensitivity at all to these pollens and molds will experience symptoms. Extremely sensitive people could have severe symptoms.|
* These mold levels were determined based on outdoor exposure to natural occurring spores in the environment and should not be applied to indoor exposure which may represent an entirely different spectrum of spore types.
These levels and the corresponding ranges are based entirely on ecological measurement, not health effects. Because the data were from all certified counting stations, the ranges allow comparisons between sites across the country and may be more appropriate than a range based on local numbers. This does not mean that, for some stations, some categories will never be high. Because of this, a few stations have determined the ranges for their own locations and do not use these national ranges.
