High quantities of spores from meadow and wood mushrooms (basidiospores) are usually carried in the air on October.

Currently, the amount of these spores in the air is rather limited.

Some of these spores may cause respiratory allergy.


Good to know:

  • For Cladosporium 3.000 spores per m³ are sufficient to induce respiratory problems in sensitized persons. For Alternaria 500 spores per m³ are enough.
  • Pine trees produce huge quantities of pollen grains that may be observed as a yellow deposit on different outdoor surfaces (cars, garden furnitures, etc.). This pollen does not cause allergies.
