Pollenmonotoring in Denmark

Asthma and Allergy Association

The Pollen monitoring in Denmark is rooted and done by the Asthma and Allergy Association. Asthma and Allergy Association, Denmark is a private member/patient organisation with a democratic structure. It was founded in 1971 and consisted of local organisations up until 2010. In 2010 the structure of the organisation changed to single nationwide organization instead of a federation of local associations.

Asthma and Allergy Association initiates patients' activities in the community; such as group travels combined with lectures in asthma, patient to patient knowledge sharing and evening meetings with lectures within the topic of allergy and asthma.

The main office employs 20 professionals within biology, chemistry, doctors in medicine and nurses. Furthermore a whole department is devoted to communication and members' administration.

Funding is through private funds, partnerships and public grants from National Board of Health i.e. supporting our major patient counselling service and the pollen monitoring network.

Pollen monitoring network

History

In 1977, the Danish Aerobiological group of the Danish Asthma and Allergy Association started registration of pollen and spores in Denmark.

The first pollen trap was placed at the Danish Meteorological Institute in Copenhagen. In 1979 another trap was placed at the hospital in Viborg - Jutland. They are both placed approximately 15 meters above ground. Those two traps have been running continuously. Our database contains data from up to 43 taxa from 15 pollen stations, but continuous data is only available from Copenhagen and Viborg. 

All traps in the network are Burkard 7-days recording volumetric spore traps. Identification and counting of pollen are done according to standard methods.

Until 1986 most of the work was done voluntarily and was funded by private investors. In 1986 the pollen registration network obtained governmental founding through the National Board of Health and has since been professionalized by the Asthma and Allergy Association in collaboration with the Danish Meteorological Institute (DMI).

Today we collaborate with the danish met office (DMI) and National Environmental Research Institute (NERI), University of Aarhus on issues of weather, pollen forecast and development of dynamic models for pollen prognosis on local and regional scale.

We also collaborate on research projects with NERI and Department of Environmental and Occupational Medicine, University of Aarhus. The aim is to provide knowledge and better information to allergy suffers on pollen, air pollution and allergy.

Pollen information

The daily pollen count of the six most important pollen types and two spore types are published. This is alder, hazel, elm, birch, grasses, and mugwort, and spores from Alternaria and Cladosporium.

Since 1981 pollen forecasts for birch, grasses and mugwort has been prepared and also communicated to the public. The scores are relatively high as in a normal season 70-80% of the pollen forecasts are correct.

Pollen prognoses are an automatic product launched on the internet in summer 2005. It gives much more detailed information on the expected pollen concentration of birch, grass and mugwort in Denmark for every six hour up to two days ahead.

Communication to the public is done by e.g. free e-mail service, applications for mobile phone and Iphone, Internet pages, written and visual medias.
