[Study of pollen of allergologic significance in the urban atmosphere of Parma in the years 1983-1984].

From 1983 to 1984 pollen air samples from Parma's urban atmosphere were collected weekly by means of a Burkard recording volumetric spore trap. Data regarding a few of the meteorologic variables were also collected at the same time: temperature, insulation, water precipitation, humidity and wind speed. Some of the more allergenic pollens and their concentration/m3 air were determined from the collected samples: Graminea, Urticaceae, Fagaceae, Salicaceae and Betulaceae. Looking at the results from the period of study, it can be seen that Graminea and Urticaceae were the most represented in comparison with the other families. Graminea was most represented in May 1983, in June 1984 and during the first week of September 1984; Urticaceae in September 1983, May 1984 and September 1984. These pollen concentrations were also compared to the meteorologic data.
