In the urban area there is a growing human population and fixed and movile sources of pollutants.
Epiphytyc lichens as sentinels for heavy metal pollution at forest ecosystems central Italy. Up to date, between 17, and 20 thousand variants have been identified, including 1, lichenicholous fungi.

A new scale for the interpretation of lichen biodiversity values in the Tyrrenian side of Italy. By means of bioindiccadores analysis, using the biotypes as units, we found that the biotypes “Yoshimuriella”, “Usnea apothecia “, “Usnea pigmented “, “Parmotrema soredia “, “Lobariella apothecia “, lquens green “, “Psiloparmelia”, and “Hypotrachyna soredia ” were statistically indicative of the conserved forest, whereas the biotypes “Hypotrachyna isidia “, “Usnea pendulous “, “Parmotrema isidia ” and “Heterodermia apothecia ” were representative of the disturbed forest.

EVALUACIÓN DE LOS LÍQUENES COMO BIOINDICADORES DE LA CONTAMI by eden sierralta on Prezi
A retrospective study using epiphytic lichens as biomonitors of air quality: In this regard, bioindicadoree is estimated that a significant number of substances will be discovered in the coming years, taking into consideration that only a low proportion has been analyzed from available lqunees sources. Also, these organisms present antitumor action inhibiting different types of cancer. The lichen specimens sampled, in the disturbed and in the conserved forest, corresponded to 54 species, with the genera Parmotrema specimens, 5 speciesUsnea specimens, 7 speciesHypotrachyna 79 specimens, 7 speciesPhyllopsora 63 specimens, 2 speciesand Sticta 49 samples, 6 species most representative.

Bioondicadores results would indicate homogeneity in the air in the study areas, even though the areas chosen have remarkable differences in ground use urban area vs. Air lqueenes monitoring on the Tongass Nacional Forest. Likewise, they are used in the field of cosmetics and in pharmaceutical preparations.
The urban area was compared against two control areas with no pollution sources. We sampled 32 “encenillo” trees Weinmannia tomentosa16 in each fragment, using three subsamples per tree at three height levels, for a total of 32 samples trees and 96 subsamples.

Kluwer Academic Publishers, Netherlandspp. A large quantity of natural products and biomolecules have been isolated and characterized from plants, lichens, fungi and sea organisms; in particular, more than thousand secondary metabolites have been extracted from plants.
Ediciones Omega, Barcelona, pp. With regard to their medicinal use, lichens are used in the treatment of pulmonary tuberculosis and as vermicide. Users should refer to the original published version of the material for the full abstract.
