catalase, metal tailings, plants, mine, Trepča https://unilib.phaidrabg.rs/o:3418 doi:10.5937/sustfor2081053 ISSN: 1821-1046 The environment of Northern Kosovo and Metohija has been remarkablyinfluenced for a long time by the huge metallurgical complex “Trepča”. The technologicalprocess of ore exploitation and processing in the Mining and Metallurgical ChemicalCompany “Trepča” has resulted in a large amount of discharged material, deposited onmetal tailings that are mostly located in inappropriate areas, partially covered withvegetation, mostly consisted of several invasive plants. The activity of the enzyme catalase was investigated in plant species collected from abandoned metal tailings “Žitkovac” andcompared with the same plant species from the environment from the vicinity of Niš city.Measurements of enzyme activity were carried out in the underground and above-groundparts of plant species Artemisia vulgaris, Cichorium intybus, Erigeron canadensis, Robinia pseudoacacia, Medicago sativa, Teucrium chamaedrys, Plantago lanceolata, Rumex acetosella, Tanacetum vulgare and Euphorbia cyparissias using gasometric method. Theresults have indicated that an increase of catalase activity in tested plants from the metaltailings is possibly a consequence of stress caused by specific environmental conditions. info:eu-repo/semantics/article eng application/pdf 673732 bytes Institute of Forestry, Belgrade 2022 Marković, Marija S.
