At DMI (Danish Meteorological Institute)
og AAD ()
you can find a lot of info about pollen.
Pollen from plants are collected continouesly in Lyngby (on the roof of DMI) and in Viborg (at the regional hospital). Spores from a couple of fungi are also collected at DMI. Once daily - usually around 12 am - pollen collected during the last 24 hours are taken out. The pollen are counted at AAD through a quite complicated prceedure. The result is published daily by DMI and AAD at around 4 pm.
Quite many plants have preferred the wind to take care of their pollination to bees and other insects. It is a characteristic for these plant's pollen what they are very small (about 2.5 to 250 micrometer; 10-6; 1/1,000,000 meter) and are produced in very large quantities. The spreading viries considerably between the individual species from under 1 kilometer to several hundred kilometers. The pollen from birch are believed under certain circumstances to be able to travel up to 3,000 kilometer.

Ragweed is quite seldom in Danmark. It is a socalled "Invasive specie" and Naturstyrelsen (Danish Nature Agency)
recommends that it when found is exterminated (put into the dust bin). It is more allergenic than mugwort and has a longer season.
Quite a number of mould fungi can be found both out- and in-doors, where they break down plants etc. They prefer / need high humidity to thrive. Their spores can cause allergy. Two of them are Altenaria and Cladosporium. Their level of spores is shown daily as part of the pollencount for Copenhagen (København).
The description "dasmp-stained" is often related to Altenaria.
The most frequent fungi within the group called "mould".
