Líquenes como bioindicadores de poluição atmosférica

Abstract

Numa altura em que existem os mais variados equipamentos tecnológicos de avaliação da qualidade do ar recorrer a um organismo vivo para esse efeito não parece uma grande inovação a não ser que traga algum tipo de vantagem adicional, como seja permitir avaliar os efeitos da contaminação para além dos valores instantâneos obtidos por medições químicas. Os líquenes são seres vivos com características particulares, as hifas do fungo absorvem água diretamente da atmosfera, e por isso são particularmente sensíveis à poluição ambiental tornando-se um recurso a que qualquer pessoa pode recorrer para ter uma ideia da qualidade do ar que respira. Foi isso que tentámos fazer neste trabalho, identificar e comparar os líquenes de três locais, determinar a espécie a que pertencem e inferir sobre a qualidade do ar do local de onde os recolhemos, relativamente à quantidade de SO2 presente.
