Temporal variations in airborne Alternaria and Cladosporium spores and the effect of meteorological factors: three years study from a metropolis on the West Anatolian coast
摘要
Investigating airborne fungal spore concentrations and the effects of meteorological variables on them, as well as evaluating potential source areas that contribute to spore concentrations, is critically important for managing agricultural damage caused by these spores and improving the quality of life of individuals affected by spore-related allergies. In this study, the atmospheric concentrations of Alternaria and Cladosporium spores and the meteorological factors influencing these concentrations were investigated over a three-year period (2020–2022) in İzmir, a metropolitan city located on the western coast of Anatolia. Spore samples were collected throughout the study period using a volumetric spore trap (Lanzoni VPPS 2010). Correlation analyses revealed that daily average temperature and daily average wind speed showed the strongest significant associations with spore concentrations. Moreover, wind direction had a significant effect on spore concentrations. Winds originating from the northern parts of the city, where grasslands and agricultural areas are more prevalent, were particularly associated with higher spore concentrations. This study is the first multi-year spore monitoring research to report the atmospheric concentrations of Alternaria and Cladosporium spores in the city of İzmir, and it also highlights the importance of meteorological variables and emission sources in the seasonal dynamics of these fungal spores.
