This project is based on the study of lichen in the region of Benavente y los Valles, pointing out the correlation betwee.
n lichen and the quality of the air in different regions.
The biological indicators of pollution or bio-indicators are based on the analysis of the sensitivity presented by some species of living beings to determine atmospheric gaseous pollutants, which effects allow us to identify the presence and observe the evolution of the atmospheric pollution.
The lichens are symbiotic associations between an algae, a yeast and a fungus. These interactions originate a stable thallus with a specific structure and physiology. makes these living beings excellent bio-indicators, (the best ones regarding the quality of the air).
