There is almost no more allergenic pollen present in the air.
High densities of spores of mushrooms from meadows and forest (Basidiomycetes) are present in the air. Some of them might cause respiratory allergy.
Good to know:
- Indiviual sensitivity may vary a lot. It is reported in literature that 3000 spores of Cladosporium per m³ are enough to induce allergy symptoms to sensitized persons.
