Abstract

RAMOS, Roberto  and  MEZA, Víctor. Occurrence of Cladosporium in the atmosphere of the Plaza San Martín (Lima, Peru) and their relationship to some meteorological factors. Ecol. apl. [online]. 2018, vol.17, n.1, pp.39-43. ISSN 1726-2216.  http://dx.doi.org/10.21704/rea.v17i1.1171.

The objective of this study was to detect the allergenic fungus Cladosporium in the atmosphere of the Plaza San Martín of Lima (Perú) and to analyze the influence of the meteorological variables on its concentration. Air sampling was performed using a one-stage Andersen type volumetric impact equipment. Cladosporium conidia are present in the atmosphere of Plaza San Martín throughout the study period, however, the highest concentrations were observed in the months of March and September. A positive statistical correlation was found between the concentration of Cladosporium conidia and the wind speed and UV index. The effect of the air temperature showed a weak positive correlation on the concentration of Cladosporium, however, the relative humidity presented a negative correlation. Identification of climatic factors favoring the release of conidia may improve current methods of allergy prevention, early detection of plant infections or respiratory diseases in humans.

Keywords : bioaerosol; conidia; airborne; spore; allergy; meteorological factors.
