Knowledge about trends in environmental pollution is of great importance for understanding temporal changes in exposure and functioning of ecosystems; moreover, this knowledge is essential also for reliable assessment of effectiveness of different mitigation measures done on dispersed as well as on point emission sources. Annual rings and bark pockets of trees may be a useful tool for retrospective determination of trends in environmental pollution and for detection of predominant emission sources in a given period of time; however, this potential has not been adequately used in Slovenia so far. Therefore, the main goals of the proposed project are as follows: (i) selection of the most suitable tree species for historical biomonitoring of environmental pollution with heavy metals; (ii) determination of above mentioned temporal trends in four areas of Slovenia (the Šalek Valley, the Upper Meža Valley, Zasavje region and Kočevsko region, respectively); (iii) determination of predominant emission sources in the given period of time; (iv) evaluation of effectiveness of some measures done on big emission sources in study areas; (v) comparison of historical trends among four areas of Slovenia, area with an important natural emissions of heavy metals due to volcano activity (Etna mountain, Sicily), and boreal area of northern Norway as a typical control region, respectively. A proposed research project has an important scientific as well as applicative value, since it will significantly contribute to: (a) development of a bioindication as a basic research field; (b) new scientific findings on changes in environmental pollution and ecosystem burdening in Slovenia; (c) evaluation of effectiveness of some measures orientated toward reducing emissions of different hazardous substances.
