o:38538 Assessment of cabbage potential for heavy metal phytoremediation on fly ash landfill substrate en ABSTRACT Coal combustion produces large amounts of ash, often deposited in open landfills without vegetation, posing environmental risks. Vegetation stabilizes ash, reduces erosion and pollutant mobility, and provides organic matter. Brassicaceae species, such as cabbage, can absorb heavy metals, making them suitable for phytoremediation. This study evaluated cabbage (“srpski melez”) growth and metal accumulation on a fly ash landfill in spring 2023. Substrate and plant samples were analyzed for pH, organic carbon, total nitrogen, N, P, K, Mn, Ni, Pb, and Zn. Germination and biomass were lower on ash, but metal concentrations in plants remained below phytotoxic thresholds. Cabbage grown on ash can phytostabilize zinc and phytoextract manganese and lead. fly ash landfill, phytoremediation, Brassicaceae, heavy metals 1552099 10.46793/SBT26.015S 2026-04-01T06:57:27.031Z 44 yes 46 Aleksandar Simić University of Belgrade, Faculty of Agriculture, Belgrade, Serbia Gordana Andrejić University of Belgrade, Institute for the Application of Nuclear Energy INEP, Belgrade, Serbia doktor nauka-ekološke nauke person 0000-0002-0000-0097 Đorđe Moravčević University of Belgrade, Faculty of Agriculture, Belgrade, Serbia person Snežana Brajević University of Belgrade, Institute for the Application of Nuclear Energy INEP, Belgrade, Serbia person 0009-0008-7964-8235 application/pdf 260334 https://phaidrabg.bg.ac.rs/o:38538 no yes 21 70 92000001 11A33 11A29 11A2906 4th INTERNATIONAL SYMPOSIUM ON BIOTECHNOLOGY-Proceedings, 2026 15 23 Faculty of Agronomy in Čačak, University of Kragujevac, Serbia 2026
