Birch pollen and antigens were collected on sampling tape of the Burkard Seven-day-recording Pollen and Spore Trap before, during and after the pollen season. The antigens were then transferred to a polyvinylidene difluoride (PVDF) membrane. For dete

Long term observations of atmospheric pollen offer the possibility of studying patterns in fluctuations in the airborne pollen presence. In this study, birch pollen measured at five monitoring stations in Europe with records of 18 to 30 years, have b

To determine the variation of antigenic water soluble proteins in white birch ( Betula pendula ) pollen, extracts of pollen from different sides of individual trees were analyzed by i

The present paper describes a vast dustfall with snow in northern Fennoscandia, 10 March 1991. The area affected by dust deposition was at least 320,000 km2. and the particulate mass received amounted to between 50 and 200 mgm−2. The total amounts

Under favourable conditions, a considerable amount of long-distance transported pollen can be deposited far from its place of origin. In Fennoscandia, in most cases, such situations occur when there is a strong southerly air circulation from South-Eu

Birch pollen concentrations recorded by volumetric sampling for a three year period on the rural Baltic island, Gotland, are presented and compared with the birch pollen records for the same period in Stockholm. Since the incidence of birch pollen al

By means of regression analysis the Cladosporium and Alternaria spore counts for 1980–89 for Stockholm are explored and modelled at 6-hour intervals in order to find the relationship between spore presence and climate for the same time periods. Six

An example of the potential importance of air masses as carriers of aero-allergens from distant source areas is provided. Considerable amount ofBetula pollen is relatively often transported to Fennoscandia before the local birch flowering period, mai
