“…The processes and dynamics of heavy metals between soil-to-plant and trophic transfer to food chains are reported widely (Briffa et al, 2020;Liang et al, 2016;Mahmood and Malik, 2014;Nica et al, 2012;Orisakwe et al, 2012). These heavy metals find their sinks through consumption by human beings and other living organisms (animals, ranging from aquatic to terrestrial) from plants along the food chain (Ali et al, 2019a,b;Nica et al, 2012;Wahab et al, 2012).…”

This study assessed and classified the phytoremediation potentials of selected plant species around gold mining areas in restoring the environments contaminated by heavy metals. The geographic focuses of the study were the Golden Pride Gold Mine (GPGM) and Geita Gold Mine (GGM) in Tanzania. The shoots and roots of plant species surrounding the mining areas and the samples of associated soils were collected and analysed for total concentrations of lead (Pb), chromium (Cr), cadmium (Cd), copper (Cu), arsenic (As), manganese (Mn) and nickel (Ni) using Atomic Absorption Spectrophotometer (AAS) and UV-VIS spectrophotometry. Results indicated that the soils from study areas were loamy textured and slightly acid (pH 6.1-6.5), soil organic carbon and organic matter were low (0.6-2.0%), total nitrogen was very low (<0.10%), phosphorous ranged from low (6-12 mg kg À1 soil) to high (13-25 mg kg À1 soil), and cation exchange capacity ranged from low (6.0-12.0 cmol (þ) kg À1 soil) to medium (12.1-25.0 cmol (þ) kg À1 soil). In assessing heavy metals using plant parts, the roots of giant rats-tail grass (Sporobolus pyramidalis) accumulated highest Pb (757.78 μg g À1 ), Creeping Blepharis (Blepharis maderaspatensis) the Cd (158.11 μg g À1 ), lantana (Lantana camara) the As (68.61 μg g À1 ), and leuceana (Leucaena leucocephala) accumulated higher Mn (2734.61 μg g À1 ) and Ni (4464.33 μg g À1 ). In shoots, L. leucocephala accumulated higher Cr (1276.67 μg g À1 ) and higher Cu (2744.44 μg g À1 ) in L. camara. Although S. pyramidalis, M. repens, L. camara, B. maderaspatensis and L. leucocephala are likely to pose hazards to herbivores (grazing animals) while entering the food chain, they are still potential hyperaccumulators thus can be used to decontaminate metalliferous affected soils. Blepharis maderaspatensis has never been reported anywhere as Pb, Cd, Cu, Mn and Ni uptake plant hence this can be regarded as a new finding.

“…In contrast to our findings, Jung (2008) found that there were positive correlations in Pb concentrations between the soil and in the plant organs of six crop plant species. Further, by increasing soil concentrations Liang et al (2016) demonstrated increasing Pb concentrations in plants. We demonstrated significant positive correlations in Cr concentrations between the soil and the roots of C. album.…”

Remediation with plants is a technology used to decrease soil or water contamination. In this study we assessed the remediation potential of two weed species (Chenopodium album and Tripleurospermum inodorum) in a moderately metal-contaminated area. Metal concentrations were studied in roots, stems and leaves, in order to assess correlations in metal concentrations between those in soil and plants. Furthermore, we calculated bioaccumulation factor (BAF), bioconcentration factor (BCF) and translocation factor (TF) values to study the accumulation of metals from soil to plants and translocation within plants. We found correlation in metal concentrations between soil and plants. The metal accumulation potential was low in both species, indicating low BAF and BCF values. In contrast, high TF values were found for Mn, Ni, Sr, Zn, Ba, Fe, Cu and Pb in C. album, and for Fe, Mn, Ni, Zn and Sr in T. inodorum. Our results demonstrated that the potential of C. album and T. inodorum might be limited in phytoextraction processes; however, when accumulated, metals are successfully transported to aboveground plant organs. Thus, to achieve the efficient remediation of metal-contaminated soils, removal of the aboveground plant organs is recommended, by which soil disturbance can also be avoided.

“…Eredményeinkkel ellentétben Galfati et al (2011) rokon fajoknál a talajjal összevetve szignifikáns pozitív korrelációt igazoltak a Cd, Cu, Ni és Zn kapcsán. Tizenhárom növényfajt, köztük a fehér libatopot vizsgálva Liang et al (2016) eredményeinkkel ellentétben szintén szignifikáns pozitív korrelációt tapasztaltak a Cd, Cu, Pb és Zn esetében. A Cr vizsgálatakor Samantaray et al (2001) szignifikáns pozitív korrelációt találtak a talaj és négy fafaj fémkoncentrációja között.…”
