“… 10 Artemisia species and especially Abronia fragrans growing on contaminated soils are able to accumulate Zn, Cd, and Cu in their aboveground parts without displaying any toxicity symptoms. 41 The HM accumulation in plants depends on their biological (species) characteristics and on external natural and anthropogenic factors. 11 Thus, the qualitative characterization of HM-induced inhibition of plants based on external signs seems insufficient, due to the presence of evolutionarily developed mechanisms of adaptation to adverse environmental conditions.…”

A study on Artemisia austriaca of two anthropogenically heavy metal-polluted impact zones of the Rostov region, namely Lake Atamanskoye and Novocherkasskaya Power Station, was conducted. The influence of soil pollution on the Pb, Zn, and Cu accumulation in various organs of A. austriaca , which is widespread in the studied territories, was established. An extremely high level of Zn content (3051 mg/kg) was observed in the soils of the impact zone of Lake Atamanskoe, as well as an excess over the maximum permissible level for Pb and Cu (32 and 132 mg/kg accordingly). The distribution coefficient (DC) of heavy metal translocation showed the highest mobility of Zn (DC ≥ 1 in 9 out of 11 sites) and the smallest of Pb (DC ≥ 1 in 4 out of 11 sites) in plants of the Novocherkasskaya Power Station impact zone. The zone of increased pollution around Lake Atamanskoye was 1.5 km, which was much smaller than the Novocherkasskaya Power Station zone of high pollution (5 km). However, vehicle emissions accumulated in the soil over the past decades had a greater effect on the Pb translocation than atmospheric emissions of the enterprise.

“…HMs could not be biodegraded, and exist in the environment indefinitely, and may threaten human health by entering the food chain ( Kanwar et al, 2020 ). Some of these HMs (such as Cd, Pb, and Hg) are not essential, whereas others (such as Fe, Mn, Cu, Mo, and Zn) are essential micronutrients for plant growth but excessive concentrations affect the plant development ( Alirzayeva et al, 2017 ). Concurrent occurrence of cadmium (Cd) and copper (Cu) stresses has been shown to be more detrimental to crop production.…”

“…They are known to accumulate to alarming levels in food chain through the soil contamination 5 . Some of these (like Cd, Pb, and Hg) are not necessary, while others (like Cu, Fe, Mn, Zn, and Mo) act as essential micronutrients for plant growth, and excess concentrations affect plant development as well as wide range of physiological and biochemical processes 6 . Phytoremediation is the use of plants (with or without the associated microorganism) for the treatment of notorious contaminants.…”

Up till now, despite of well-developed ornamental market, very little information is available on Petunia hybrida L. tolerance against heavy metals (HMs), which can contribute in both beautification of urban dwellings, as well as potential in phytoremediation. Therefore, hydroponic study was conducted to check the effects of Cd, Cr, Cu, Ni and Pb individually (50 and 100 μM) and with co-application of EDTA (2.5 mM) in Hoagland’s nutrient solution. Results indicated higher uptake of Cd, Cr, Ni and Pb in above ground parts, and Cu in roots, further the co-application of EDTA enhanced HMs uptake in P. hybrida L. This uptake accompanied changes in biochemical stress indicators, included significantly higher MDA, H2O2 contents and electrolyte leakage with reduced chlorophyll a, chlorophyll b, total chlorophyll and carotenoid content. Upon exposure to HMs increased antioxidant enzyme activities (CAT, POX, GST, APX, and SOD) were noted. Though selected HMs can be removed by using P. hybrida L., the findings of current study indicated that the direct exposure of P. hybrida L. to Cd, Cr, Cu, Ni and Pb damaged the plant’s aesthetics, and to use P. hybrida L. for beautification of urban landscape or phytoremediation, appropriate soil modification should be included.
