Abstract

Airborne pollen is the cause of common, plant-group-specific allergies. The aim of this study was to assess the spatial and seasonal variations of airborne pollen concentrations in the city of Szczecin in north-western Poland. Daily monitoring of the concentrations of airborne pollen from sorrels (Rumex spp.), plantains (Plantago spp.), nettles (Urtica spp.), and goosefoots (Chenopodiaceae) was carried out using volumetric and gravimetric methods over the four-year period from 2000 through 2003. A pollen season was defined as the period in which 95 % of the total annual pollen catch occurred. The longest overall pollen season was recorded in 2000. The maximum total annual catch of Plantago and Urtica pollen occurred in 2001, of Chenopodiaceae pollen in 2002, and of Rumex pollen in 2003. The Urtica pollen season started in late July and lasted 61-83 days. The Rumex pollen season started in May and lasted 80-139 days. The Plantago pollen season started in May or June and lasted 82-124 days. The Chenopodiaceae pollen season started in June or July and lasted 82-98 days, but pollen concentrations were low even at the maxima. The comparison of pollen concentrations from four city districts of Szczecin shows that Rumex pollen was most abundant at the city centre in Śródmieście district, while Plantago, Urtica and Chenopodiaceae pollen was most abundant in Zelechowa, a village-and-garden district. In general, pollen concentrations were significantly correlated with maximum daily air temperature and relative humidity, but only the Rumex pollen concentration was significantly correlated with precipitation.
