Methods of analysis
Each station collects pollen and fungal spores 24h/24h with a “Burkard Volumetric Spore Sampler” unit. The upper part of the sampler rotates, driven by the wind vane. Air is sucked into the sampler through a calibrated slit and is captured on a prepared adhesive tape at a set rate corresponding to the human respiration rate (10 l per minute).
The sampler is located on a roof. This allows to obtain mean data, representative for an area of 20 to 30 km around the station.
