Abstract: Based on systematic data from 1988 to 2015, the main sources of soil contamination in forest and industrial areas of Bulgaria were presented. The processes of soil acidification and eutrophication as well as accumulation of heavy metals in forest and industrial soils were analysed. The content of heavy metals in soils, pasture grasses and medicinal plants from two National Parks--Central Balkan and Pirin, as well as from two Natural Parks--Bulgarka and Strandzha was also reported. Data on heavy metals accumulation in leaves of tree species in some industrial areas of the country were presented as well. Soil and plant contamination with heavy metals were estimated according to the applied criteria of ICP Forests.
