• Abstract:

  Green areas are key factors when it comes to quality of life and air quality, besides the aesthetic quality that brings to the city, offers better quality physical and mental health of the population, so using bioindicators in these areas as a source of instrument for air quality is of due importance. This paper presents an analysis of the Napoleão Moreira da Silva Square (Maringá - PR), specifically the lichens present on the tree trunks, as a bioindicator of air quality, making a comparison of the years 2006 and 2018. The Helmut Troppmair methodology was used, in which the quantification of the lichens makes it possible to infer the quality of the air at that location. The data obtained were studied both in the form of sectors, one representing each street, and in the square in general. Thus, it was possible to observe that the pollution presented differences in the sectors with greater presence of lichens in 2006, but in the general average, the data in relation to the classification proposed by Troppmair remained the same.
