COMPARISON OF AIRBORNE POLLEN COUNT AT 3 MEASURING STATIONS - DAVOS-WOLFGANG, WIESEN GR AND BASEL

During the vegetation period of three years (1991-1993) there have bee n investigations among others at three measuring stations in Switzerla nd: Davos-Wolfgang (1600 m), Wiesen GR (1450 m) and Basel (273 m above sea level). The research concerned the amounts of airborne pollen of the ash, the birch, the grasses and the mugwort. It is obvious that es pecially the amount of grass pollen in Wiesen is much higher than in D avos and nearly equal to the amount in Basel. This was not expected. H owever, the flowering of plants is later in the mountains in lower lyi ng stations. The allergic patients should take this into account when they choose the time and the altitude to go to the mountains.
