Soil Contamination in Forest and Industrial Regions of Bulgaria

A comprehensive analysis of soil contamination in Bulgaria's forest and industrial regions reveals significant accumulation of heavy metals, particularly in Pirin National Park, Central Balkan National Park, Bulgarka Natural Park, and Strandzha Natural Park. The study, spanning 1988 to 2015, highlights severe soil acidification and eutrophication, with notable levels of heavy metal contamination detected in pasture grasses and medicinal plants. Industrial areas also show elevated heavy metal concentrations in tree leaves, assessed using ICP Forests criteria. This research underscores the environmental impact of industrial activities on pristine ecosystems, including UNESCO World Heritage Sites like Pirin National Park.
