“…Branzini and Zubillaga reported that Pb, Cu, and Cr had a higher affinity for the reactive solid phases in carbonate soils than Ni, Zn, and Cd. The active role of amorphous Al silicates and interaction between organic matter (compost) and clays results in the formation of organo‐clays, which improve the adsorbing capacity of soils and also increase the metals competition …”

“…Nanoparticles of Al 2 O 3 are considered efficient in removing Cd, Zn, and other PTEs from wastewater and soil solutions due to their high specific surface area and surface area to volume ratio. It was concluded that PO 4 was the most efficient among the three ligands for increasing Zn and Cd adsorption by forming stable, insoluble mineral metal‐phosphate and thus reducing their mobility …”

Contamination of soil and water with potentially toxic elements (PTEs) has become a global environmental concern that could pose potential risks to human health and agriculture. The major anthropogenic sources of PTEs contamination include coal combustion processes, leather tanning operations, mining, smelting activities, and use of sewage water for irrigation. Scattered studies are available in the literature that determines the sources, bioavailability, and potential hazards due to PTEs contamination to crop plants and, ultimately, to human beings. This article reviews how solid‐ and solution‐phase chemistry of soil and existing plant species influence the bioavailability of PTEs to cereal and legume plants, along with the mechanisms involved in the uptake and accumulation. This article also describes the phytotoxic effects of PTEs and strategies to overcome these toxic effects by identifying highly tolerant cereals and legumes. Moreover, this article also summarizes recent advances in the field application and discusses perspectives to reduce PTEs accumulation in cereal and legume crops.

“…The TF value >1 indicates that the plant can translocate the heavy metals absorbed by the plant roots the plant shoots. The translocation factor is determined based on the ratio of the concentration of metal in the plant shoots to the concentration of metal in the roots (Branzini and Zubillaga, 2013).…”

This study aimed to determine the types of hyperaccumulator plants that can absorb the heavy metal content of Pb, Cu, Cd, Cr based on the values of bioaccumulation factors (BAF) and translocation factors (TF). Results of the analysis showed that BAF value of the hanjuang plant (Cordyline fruicosa), for heavy metal Pb was 0.369; Cu 0.442; Cd 0.055; Cr 0.078 and TF value for heavy metal Pb 1.572; Cu 0.964; Cd 0.108; Cr 1.358. Croton plant (Codiaeum variegatum), had a BAF value of Pb 0.021; Cu 0.060; Cd 0.000; Cr 0.003 and TF value of Pb 3.638; Cu 0.000; Cd 0.000; Cr 1.399. Sansevieria plant (Sansevieria trifasciata) had a BAF value of Pb 0.090; Cu 0.036; Cd 0.015; Cr 0.002 and TF value of Pb 0.410; Cu 0.334; Cd 0.222; Cr 0.726. Sunflower plant (Helianthus annuus) had a BAF value of Pb 0.022; Cu 0.094; Cd 0.308; Cr 0.001 and TF value of Pb 1.930; Cu 0.399; Cd 1.383; Cr 1.361. Based on a comparison of BAF values, hanjuang plant was the best hyperaccumulator plant capable of accumulating Pb, Cu, Cr with a phytoextraction mechanism and accumulating Cd with a phytostabilization mechanism. At the same time, sunflower a hyperaccumulator plant with the best translocation factor where the roots of sunflower plants absorbed Pb, Cu, Cd, Cr, which were then translocated to the stems and leaves optimally through a phytoextraction mechanism.

“…Ideally, a good phytoextractor should have a TF > 1. It means that the plant is translocating the pollutant into the aerial part and hence is liberating the roots and rhizomes for more pollutant to be absorbed [1,[38][39][40]. However, Baker [41] proposed an additional category apart from the one mentioned above, that is an "Indicator" category, which is when uptake and transport of metals to the shoots are regulated so that internal concentration reflects external levels.…”

The Valsequillo reservoir is a Ramsar wetland due to its importance as a point of convergence of migratory waterfowl. It is located in Central Mexico and is currently endangered by the constant spill of municipal and industrial discharges from Puebla city. On this context, we evaluated thirteen potential toxic metals (PTMs) in water, Water hyacinth (E. crassipes) plants and sediments at this site. A combined number of 31 samples were collected from the study area. The degree/extent of metal contamination in sediments was assessed through different geochemical indexes, namely: Geoaccumulation index (Igeo), Enrichment Factor (EF) and Potential Ecological Risk Index (PERI). The ability of Water hyacinth plants residues as a phytodepurator in the Ramsar site was tested in terms of the bioaccumulation factor (BF) and the translocation factor (TF). The results concerning sediments showed that Pb, Cu and Hg pose a threat to the aquatic environment since Igeo and EF indicate sediments ranging from moderately contaminated to contaminated. Moreover, PERI pointed out Hg as the main contributor to the ecological risk in sediments, especially in the part of the reservoir covered by E. crassipes. Water hyacinth plants displayed good capacity to absorb PTMs from the water, since the content of Co, Zn, As, Ni, Cu, Pb, Ti, Cr, Ba, Mo and V in the total plant was (all values in mg/kg of dry weight) 21 ± 9, 408 ± 300, 12 ± 6, 93 ± 21, 93 ± 69, 53 ± 29, 1067 ± 643, 78 ± 55, 362 ± 39, 14 ± 0.6 and 96 ± 35, respectively. Metal content in sediments resembles to that of E. crassipes; especially in the roots, suggesting a constant deposition of plants at the bottom of the reservoir, which contributes to the eutrophication of the water. The present work encourages the need for a sustainable management of Water hyacinth plants in the Ramsar site, since they represent a plague and a natural phyto-depurator at the same time.
