One year of pollen monitoring in an urban network, perugia, central Italy

Abstract

Pollen monitoring at three locations in the area of Perugia is reported for the period November 1988-October 1989. A meteorological station which automatically provided data (temperature, precipitation, relative humidity, direction and velocity of wind), was located beside each trap. The study was correlated with a phonological investigation in urban and rural areas surrounding the traps in order to test the validity of using the results as indicators in a monitoring network. The aerobiological data of the three monitoring stations allows the following conclusions: 1) no notable differences were recorded during the principal period of pollination considering the flowering trends of the local anemophilous flora are taking into account, 2) from a quantitative point of view, values from Central Perugia and West Perugia were higher than those from East Perugia, 3) from a qualitative point of view, the station located in the old city area was characterized by a significant presence of Urticaceae pollen, while pollen of the Gramineae was prevalent in the two stations located in the recently built areas. © 1991 Taylor & Francis Group, LLC.
