title: A study on airborne allergenic pollen content in the atmosphere of Ascoli Piceno.
abstract: The results of 4 years (1981-1984) of monitoring airborne pollen concentration, using a volumetric trap, in the atmosphere of Ascoli Piceno (central Italy) are reported. Pollen production wasn't constant during the studied years, showing in 1982 and 1984 a very high concentration in comparison to 1981 and 1983. This is due to a dry period from April to June in 1982 and from June to July in 1984. We found that the most important allergenic pollen is Gramineae with a principal period of pollination occurring from April to July. After Gramineae, Parietaria plays an allergenic role frequently in association with the pollen of Olea, which is the most important allergenic pollen of all the trees in this area. From August to October we observed the pollination of mugwort, which was found in small quantities but nevertheless an offender in localized cases of pollinosis in Ascoli Piceno.
