The results of a biomonitoring surveys carried on in Palermo using theaccumulation of heavy metals in lichens, thalli of Xanthoria s.l. as indicators of airpollution are reported in this work. Beginning from the data of 38 simple sites shedon Palermo’s territory, has been developed a study of the air pollution in the centreof the town, the target of this work is to know the existing relationship between theconcentration of heavy metals study area and the possible pollution sources asindustry, shipyards, vehicles etc.In order to recuperate most information of the territory, the development of thiswork has been carried on with a new technology for the data management: the GIS(Geographical Information System). With this software has been possible to createa general georeferencing database with the data of the air pollution in the studiedareas, an important function of this instrument is the possibility to overlappingtheme with different information (geographical, geologic, climatic, ecological, etc)on same topographic map. With this function is possible to know new and moreinformation on the investigation area and the interaction of different aspects of theterritory.For the interpretation of the data, two-dimensional zone maps were drawn usingthe GIS program ArcView 8.3 (ESRI- Environmental Systems Research Institute,Inc.-), that with a specific extension (3D ANALYST) transforms discrete data into acontinuous distributional model.
