Avaliação da qualidade do ar por meio da utilização de Liquens

Abstract

In order to contribute to the discussion about the analysis and monitoring of air quality, the work sought to understand the relationship between lichens as bioindicators of environmental quality. From the selection of a Conservation Unit in the state of Santa Catarina, we identified the species of lichens found in a subtropical climate, analyzed the absence and presence of the species and discussed the relationship with the environment in question with the objective of to verify if the species found make it possible to understand and indicate the quality of the air. Once the classification of the lichens used as bioindicators of environmental quality was performed, analysis of photosynthetic pigment was applied, which made it possible to identify levels of chlorophyll and pheophytin in the bioindicators. The results pointed to a situation of good air quality in the study area and the research contributes with information related to the parameters of analysis of environmental degradation. In addition, an important contribution is added to the area of Biogeography with a focus on lichenology, bringing the species collected, identified and recording the existence in the study area and in the research region as bioindicators of environmental quality.
