This work deals with the study and selection of suitable bioindicators for the assessment and detection of environmental contamination by platinum metals. Lichen (Xanthoria parietina), moss (Pleurozium schreberi) and needle (Pinus nigra) were tested as bioindicators. After optimization of the analytical procedures for decomposition, pretreatment, preconcentration and determination of platinum and palladium, platinum metals contamination in areas with high car traffic was determined by the original species technique. The contamination of the environment was determined depending on the distance from the source of pollution and also the sorption capacity of these individual biomaterials was tested. A higher content of platinum metals was found in lichen samples, then in moss and the lowest concentrations were found in the needles. The platinum and palladium concentrations ranged from units to tens in ng.g-1 and the high bioavailability of palladium was confirmed.The most appropriate bioindicator was lichen and can be recommended to monitor the content of bioavailable forms of these elements in the environment. There was no confirmation of the massive spread of these pollutants over longer distances, the highest concentration values being found in the immediate vicinity of the road. In particular, the increasing concentrations of these metals have been confirmed in the environment, as well as in biomatrics.
