Heavy metal accumulation in plants is a critical aspect of phytoremediation strategies aimed at mitigating environmental pollution. A study was conducted in which we investigated the heavy metal accumulation in Sudan grass ((Sorghum bicolor (L.) Moench × Sorghum sudanense (Piper) cultivated in a contaminated area located in Lovász-zug. We monitored metal accumulation in the roots, stems and leaves to assess their remediation potential. Through analysis, we identified notable variations in the accumulation capacity of different metals within the plant organs with time. Based on the results obtained, our study concluded Sudan Grass as a tolerant plant species in soils with low to moderate levels of contamination. The main depository organ of Sudan grass is the root. It can be effectively utilized to phytoremediate heavy metal contaminated soils through extraction, stabilization and transfer processes in the plant organs. The findings prospects Sudan grass as a promising candidate for phytoremediation.
