Abstract
In the present work, the greatest interest and concern about the indoor air quality arises due to the tendency of increasingly occluded buildings, due to the control of air conditioning, noise, and for aesthetic reasons. Therefore, the sick buildings syndrome (SED) emerges, which associates with the relation between cause and effect of indoor air quality conditions, characterized by poor air renewal which allows the accumulation of pollutants inside those spaces being these chemicals and microbiological pollutants, capable of foment adverse effects to the health of the occupants. In this context, the objective of this research is to investigate the air quality of six indoor environments in an education institution - Instituto Federal do Espírito Santo – IFES – Campus Vitória and critically analyze the main Brazilian legislation in the topic – ANVISA Resolution No. 9 of 2003. For the characterization of indoor air, temperature, relative humidity and bioaerosols (fungi suspended in the air) were sampled and quantified, and the results were confronted with the maximum values allowed by the resolution. The analysis of fungal growth and the concentration of bioaerosols in the environments and their use conditions. The parameter analyzed, bioaerosols, no result was higher than the recommended by the resolution. The critical analysis of the legislation indicated some defaults and shortcomings in the requirements, such as the as the inexistence of exhibition limits to pollutant in short or in long period, the lack of microbiological parameters for concentration of bacteria in the air, and the lack of recommendations for monitoring growth of fungi in Petri plate. Thus, from the responses achieved, improvement proposals were made for the environments, the ventilation system and in the resolution in order to improve the internal air quality and therefore, to ensure the well-being and comfort to the occupants.
