“…The Pb concentration was lowest in forage peanut roots showing a significant increase in Pb translocation to the leaves (Figure 3). This finding is contrary to those reported by Santos et al (2012) and Romeh et al (2016) who reported higher amounts of lead in roots than in shoots.…”

This work evaluated the potential of lead (Pb) phytoextraction by forage peanut, Arachis pintoi, cultivated on an Oxisol and a Gleysol. The samples of these soils received Pb as lead acetate heptahydrate (Pb(C2H3O2)2.7H2O) at rates of 0, 150 and 300 mg kg -1 . The plants were cultivated in pots filled with Pb contaminated soil, and 105 days after planting were collected to determine shoot and root dry matter. Lead contents in soil and plant samples were determined using an atomic absorption spectrophotometer. Lead did not affect shoot dry matter yield in both soil classes, but linearly reduced root dry matter. The highest Pb concentration in the plant was detected in the A. pintoi shoot. This species is not a Pb accumulator but may be considered Pb tolerant and is indicated for revegetation programs in Pb-polluted soils.

“…Accordingly, the ranges of background toxicity of small elements in plants are Pb 30-300 mg kg -1 and Zn 100-400 mg kg -1 (Nadgórska- Socha et al 2013a, b;Kabata-Pendias and Pendias 2001). It was also noted that certain species, such as P. major, have the potential for soil phytostabilisation (Romeh and Khamis 2016).…”

The aim of the study was to determine the state of the environment in Sosnowiec (southern Poland) based on the ratio of air pollution tolerance index (APTI) and the determination of concentrations of selected metals in soil and plant material. The study was conducted in ten stands: five of them were identified as 'polluted' and five as 'clean' stands. The metal content was evaluated by the atomic absorption method. For APTI calculation, analysis of total chlorophyll concentration and relative water content, the pH of the extract from the leaves was used. Analysis of the bioaccumulation of metals in the leaves revealed excessive concentrations of Pb (32.4 mg kg -1 ) and Zn (129.78 mg kg) at the KWK (coal mine) and Las (forest) stands. Higher capacity accumulation of Pb and Fe was characteristic for Plantago lanceolata. The permitted content of Pb (762.6 mg kg -1 ) in the soil samples collected at the Cedler stand was exceeded. Elevated levels, higher than the permissible concentration of Cd, were documented in soil samples from most stands within the city. In soil samples collected at the Cedler stand, Cd concentration was almost 15 times higher than acceptable for soil (4 mg kg -1 ). Based on the scope of the APTI 4.4-9.42 index obtained for the studied species, they should be considered sensitive plants. All selected species can be used as bioindicators for environmental pollution.

“…Mentha aquatica retained Cd in the root system and limit Cd translocation from root to shoot. High BCF values could be attributed to the high levels of heavy metal accumulated in roots (Romeh et al 2016). In F. subpinnata, both BCF and TF higher than one showed this plant could be appropriate for Cd phytoextraction objectives.…”

“…Phytoremediation efficiency can be measured by BCF and TF. Plants with BCF > 1 and TF < 1 have the potential for phytostabilization (Romeh et al 2016;Hesami et al 2018), while plants with BCF > 1 and TF > 1 (Ladislas et al 2012;Mahdavian et al 2017) are potentially suitable for phytoextraction. Hence, M. aquatica with BCF higher than E. caucasicum and F. subpinnata could be a successful plant for phytostabilization of Cd.…”

Potential of Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. for phytoremediation of Cd-contaminated soil

In three-pot experiments, the uptake and translocation potential of cadmium (Cd) by Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. was evaluated in different Cd concentrations including 0 (control), 5, 10, 15 and 20 mg Cd kg-1 dried soil. Plants accumulated Cd in their roots and shoots without toxicity symptoms. Enhancement of Cd concentration greatly decreased plant biomass. Bioconcentration factor (BCF) and translocation factor (TF) in F. subpinnata were higher than one that indicated higher efficiency of this plant for phytoextraction of Cd from soil. The efficiency of plants in uptake and translocation of Cd depends on species, biomass production, Cd concentration in biomass and soil. Cadmium concentration in M. aquatica root was higher than shoot. Mentha aquatica with higher BCF and lower TF than one can be suitable for phytostabilization of Cd. Also, uptake index and BCF for M. aquatica showed better phytoremediation potential in comparison with E. caucasicum and F. subpinnata.
