Grasses are still  in bloom. On Thursday, the concentration reached 9 grains/m³ air in Brussels. The critical threshold of 50 grains/m³ has not been exceeded. Hayfever sufferers have to continue to take their precautions. Other herbaceous plants such as sorrels, docks and plantain are also in bloom.  The first mugwort (Artemisia) pollen grains were also collected. At the moment the air contains important quantities of allergenic fungal spores (Cladosporium).
