“…These findings are supported by other studies [58,59], which demonstrate that chromium can be permanently bound by living cells in plant roots, leading to low chromium content in aboveground parts of the plants. Similarly to this study, extreme concentrations of Cr, Ni, and Cu have been found in agricultural soils in Qatar [60] and other soils in different land-use types, that are affected by human activities, including roadside, urban and industrial areas [61].The higher concentrations of Cr and Ni found in the roots of plants in the agricultural land (POZ08) could be attributed to the application of fertilizers, which can contain heavy metals such as chromium and nickel. Several studies have reported the occurrence of heavy metals in fertilizers, and their potential impacts on soil quality and crop productivity [62][63][64].…”

Effective biomonitoring strategies are essential for identifying and assessing the sources and levels of contamination of heavy metal pollutants in urban areas, given their negative impacts on human health and the environment. This study aimed to assess the potential of common weed, Trifolium pratense as a bioindicator of heavy metal contamination in various land uses in urban areas, with a focus on Cd, Cu, Cr, Ni, and Pb. The results have shown that Cr and Ni had high bioconcentration factor (BCF) values in most sites, in comparison with Cu, Cd and Pb. Contamination factor (CF) values varied across all sites. The industrial area and old town sites had the highest translocation factor (TF) values for Cr and Ni, indicating greater transport of these metals from roots to aerial parts of plants. Differences between heavy metals (HMs) according to land use were observed; especially, Pb and Cu were more concentrated in soils than other heavy metals in industrial areas. Overall, these findings suggest that Trifolium pratense is a promising bioindicator for heavy metal contamination in various land uses in urban areas, making it a potentially valuable tool for monitoring heavy metal pollution in cities of the northern hemisphere.
