Pollen
We use the National Allergy Bureay (NAB) scale. The scale translates pollen grain concentrations to the levels above, for trees, grass and weed. Individual exposure limits will vary, some people may be more or less sensitive to different pollen types. None No pollen, plant is outside flowering season. Low Low levels of pollen. Moderate Moderate levels of pollen. High High levels of pollen. Very high Very high levels of pollen. How do we determine the levels?
