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