AB Parietaria pollen is one of the main causes of hay fever and asthma in the population, presenting a highallergenicity. That is why, in order to inform the population, it is important to determine whether its behaviourpattern is different in different parts of the city.The objective of this study was to analyze and compare the behaviour pattern of the Parietaria pollen typein two different points within the city of Malaga and to analyze the existing correlation between pollenconcentrations and the main meteorological parameters.We used two Hirst-type volumetric pollen traps, one of them installed in the periphery and the other inthe city center, between 2017 and 2019. The samples were mounted and counted following therecommendations of the Spanish Aerobiology Network. To calculate the annual pollen integral, the sumof the mean daily concentrations throughout the year was used. To calculate the intradaily variations, thevalues were accumulated every two hours, expressed as percentages of the daily total. In order to studythe relationships between meteorological parameters and pollen concentrations, Spearman correlationtests have been carried out.The values of the annual pollen integral were always much higher in the centre. Daily mean concentrationsshowed the presence of this pollen type in the atmosphere throughout the year. Regarding the intradaypattern, a more pronounced peak was observed in the city centre, while in the periphery, the distributionis more homogeneous throughout the day. The meteorological parameters play an important role indetermining the daily concentrations in the atmosphere.In the light of these results, we can conclude that it is necessary to install several sampling points withinthe same city, due to its heterogeneity and different land uses, in order to inform the population with agreater precision and, in this way, prevent respiratory allergies.
