Abstract

Fungi are eukaryotic, achlorophyllous and heterotrophic organisms, which have simpler structures, belonging to the Fungi Kingdom. They differ in size, structure, habitat, etc. The fungi regularly present in the air, called anemophiles, are responsible for a multitude of allergic processes, in addition to causing various material damages. The control of these organisms in the air of certain environments is essential to guarantee the well-being and health of everyone who works and/or frequents a place. In places with an artificial ventilation system, this control becomes even more essential, since the lack of hygiene of these systems can trigger health problems in the occupants, a situation recognized in 1982 by the World Health Organization as Sick Building Syndrome. Based on these facts, this work aims to analyze the air quality of existing cinemas in the ABC Paulista region, considering that these places are the work environment of hundreds of people and one of the main leisure areas for citizens. The collections were carried out by the method of exposure of Agar Sabouraud plates, open, during the period of exhibition of the film. After this time, the plates were closed and incubated at 37°C for approximately seven days. Next, the structures of the fungus were fixed on adhesive tape, mounted on a glass slide for observation under a microscope and, with the aid of scientific bibliography, the identification at the genus level of the airborne fungi found was carried out. The presence of fungi of the genus Penicillium, Chrysosporium and Aspergillus was observed, all with representatives of medical importance. It is considered, therefore, that although there is a smaller growth than expected and there is in fact no microbiological contamination inside the establishment, it may be a trigger for Sick Building Syndromes.
