The problem of metal-induced toxicity is proliferating with an increase in industrialization and urbanization. The buildup of metals results in severe environmental deterioration and harmful impacts on plant growth. In this study, we investigated the potential of two ornamental plants, Catharanthus roseus (L.) G.Don and Celosia argentea L., to tolerate and accumulate Ni, Cr, Cd, Pb, and Cu. These ornamental plants were grown in Hoagland’s nutrient solution containing metal loads (50 µM and 100 µM) alone and in combination with a synthetic chelator, ethylenediaminetetraacetic acid (EDTA) (2.5 mM). Plant growth and metal tolerance varied in both plant species for Ni, Cr, Cd, Pb, and Cu. C. roseus growth was better in treatments without EDTA, particularly in Ni, Cr, and Pb treatments, and Pb content increased in all parts of the plant. In contrast, Cd content decreased with EDTA addition. In C. argentea, the addition of EDTA resulted in improved plant biomass at both doses of Cu. In contrast, plant biomass reduced significantly in the case of Ni. In C. argentea, without EDTA, root length in Cd and Cu treatments was significantly lower than the control and other treatments. However, the addition of EDTA resulted in improved growth at both doses for Pb and Cu. Metal accumulation in C. argentea enhanced significantly with EDTA addition at both doses of Cu and Cd. Hence, it can be concluded that EDTA addition resulted in improved growth and better metal uptake than treatments without EDTA. Metal accumulation increased with EDTA addition compared to treatments without EDTA, particularly for Pb in C. roseus and Cu and Cd in C. argentea. Based on the present results, C. roseus showed a better ability to phytostabilize Cu, Cd, and Ni, while C. argentea worked better for Ni, Cd, Cu, and Pb.

“…The main sources of pollution in such environments are combustion products originating from traffic, city heating plants, individual furnaces, industry, construction activities, and also the inadequate storage of industrial and municipal waste [3,4]. Pollutants reach the soil through wet and dry deposition, and their further fate depends on a number of physical, chemical, and biological factors [5,6]. One of the most important groups of pollutants in the urban environment are potentially toxic elements (PTEs), which are persistent and not subjected to biodegradation; this is why they accumulate in the surface layer of the soil, from where they can easily reach the food chain [1,4,6,7].…”

“…Lead can disrupt the nervous and immune systems and can cause anaemia, nephropathy, and gastrointestinal problems, while Cr exposure can lead to skin lesions, peripheral vascular diseases, and lung, skin, and liver cancer [1,2,7,11]. On the other hand, low concentrations of some PTEs (Cu, Fe, Mn, Ni, and Zn) are necessary for some basic physiological functions [6]; however, long-term exposure to high doses of Cu, Cr and Zn can adversely affect fertility, liver function, and cholesterol levels [12].…”

“…With this in mind, it is clear that examining the impact of PTEs on the environment and human health is necessary for each individual urban setting. Although PTEs are known to be harmful, even in small amounts, due to their longer residence time, toxicity, persistence, bioavailability and ubiquitous nature, scientists agree that these properties, as well as biogeogenic distribution, depend not only on their total content, but also on their chemical speciation in the soil and other factors related to the physical and chemical characteristics of the soil [3,6]. Therefore, from the point of view of environmental protection and the preservation of human health, it is far more important to determine patterns of element speciation in the soil rather than their total concentrations [15,16].…”

The primary focus of this research was the chemical fractionation of potentially toxic elements (PTEs) and their presence in several industrialised cities in Serbia. Furthermore, their origin, contamination levels, and environmental and human health risks were assessed. The results indicated that the examined soils were characterised by slightly higher Cu, Ni, Pb, and Zn levels than those set by European and national regulations. These elevated Cu, Pb, and Zn concentrations were caused by intensive traffic and proximity to industry, whereas the higher Ni levels were a result of the specific geological substrate of the soil in the study area. The environmental risk was found to be low and there was no enrichment/contamination of the soil with these elements, except in the case of Pb, for which moderate to significant enrichment was found. Lead also poses a potential non-carcinogenic risk to children through ingestion and requires special attention due to the fact that a significant proportion of this element was present in the tested soil samples in a potentially available form. Analysis of the health risks showed that children are more at risk than adults from contaminants and that ingestion is the riskiest exposure route. The carcinogenic risk was within the acceptable limits.
