Abstract

Currently there are few studies related with the characterization of biological components present in particulate matter, whereas these can take a direct relationship with the outbreak of respiratory diseases and may also be linked to changes in climate processes. Airborne fungi are those that have their conidia or spores transported by the air, being, the main ones, basidiomycetes , ascomycetes , zygomycetes and deuteromycete . In addition to being linked within the scope epidemiological the bioaerosols can also operate in climatic processes, such as the development of ice nuclei (ice nuclei ). However few studies have been conducted involving characterization of bioaerosols in the atmosphere of São Paulo thus requiring a greater depth in the subject . Among the various methods which exist to quantify the total fungal biomass present in the atmosphere there isn't a method ideal for all situations. The aim of this work is to characterize the types of fungal atmosphere of metropolitan São Paulo, with measurements made in two places : in University City and the Pico do Jaraguá. The goal is to do a balance with the mass of particulate matter measured: by correlating the number of bioaerosols with mass and composition of particulate matter, assessing weather conditions and performing a trajectory analysis of air masses between the collection sites. To collect the material will be used the equipment Recording Burkard (Burkard Manufacturing Co., Rickmansworth , United Kingdom) operating at 10 L / min, the samples will be collected for periods of 24 hours daily and counts performed according to Rogers et al, 2001. The results will help in the characterization of airborne fungi in the atmosphere of São Paulo, allowing them to determine their seasonal and area variation, in addition to enabling the identification of species that is not possible in culture media.
