Persistently high levels of birch pollen!

With the exception of Friday, when rain is forecast, intensive pollen counts are also expected in Burgenland during the second half of the week.

The main culprit for the current pollution is the pollen of the birch. Many plants are currently in full bloom and therefore ensure high to very high pollen concentrations in the ambient air.

In addition to birch, other members of the birch family such as hornbeam or hop hornbeam are also ready to flower and can cause additional stress through cross-reactions, as the allergens of these plants are structurally very similar to those of birch.

The ash pollen season has already passed its peak in Burgenland. Only low to moderate pollen concentrations are therefore to be expected in the ambient air.

In urban areas, parks or avenues can sometimes already be affected by the plane tree can occur. However, it will be some time before large-scale flowering begins.

In some thermally favoured locations, the first grasses are already flowering. These are very localised occurrences that can currently only cause minor pollution in the immediate vicinity. The forecast data for the grass pollen season currently indicates that the grasses will be ready to flower at the beginning of May. These data are still subject to major uncertainties at the beginning of the season and will become more precise over time.

In addition to the pollen types mentioned above maple, yew, oak,poplar, sour grasses, and cypress plants are represented in the pollen spectrum. However, they only have a very low allergenic potential.
