Abstract
Los líquenes son bioindicadores de la contaminación atmosférica ya que poseen diversos
mecanismos que les permiten absorber el agua y diferentes nutrientes de la atmósfera que
están mezclados con diversos contaminante.
La aplicación de biondicadores para percibir la contaminación atmosférica tiene varios
beneficios como son la fácil aplicación, los resultados rápidos y debido a que son
organismos relativamente longevos pueden permanecer expuestos a diferentes
contaminantes por largos periodos facilitando la obtención de información acumulativa,
completa y diferenciada gracias a su capacidad de respuesta frente a las perturbaciones del
medio.
Mediante la presente investigación se pretendió crear protocolos de manejo y empleo de
líquenes como bioindicadores para detectar la contaminación atmosférica, para la
obtención de resultados rápidos y la posibilidad de proporcionar información acumulativa,
integrada y discriminada gracias a su capacidad de respuesta frente a las alteraciones del
medio, a partir de la presencia – ausencia de líquenes en los árboles de cada una de las
áreas de estudio, esto permitirá sugerir nuevas alternativas de monitoreo de calidad de aire
con costos más bajos y de fácil interpretación.
Lichens are bioindicators of air pollution and the various mechanisms that allow them to absorb water and different nutrients from the atmosphere that are mixed with various pollutants. The application of bionics to perceive air pollution has several benefits such as easy application, rapid results and because they are relatively long organisms they can remain affected to different pollutants for long periods that facilitate obtaining cumulative, complete and differentiated information thanks to its ability to respond to environmental disturbances. Through this research, it was intended to create protocols for the management and use of lichens as bioindicators to detect air pollution, to obtain rapid results and the possibility of providing cumulative, integrated and discriminated information thanks to their ability to respond to alterations in the medium, from the presence - absence of lichens in the trees of each of the study areas, this allows us to suggest new alternatives for air quality monitoring with lower costs and easy interpretation.
