Reference ranges:

Overall, Trees, Grasses and Weeds all use the same values (grains per cubic metres of air)

Overall count is the daily average of pollen grains per cubic metres of air (trees plus grasses plus weeds).

In partnership with the the UCT Lung Institute's Allergy and Immunology Unit.

As the pollen problem worsens, precise and expanded monitoring becomes even more essential.
