“…Galal et al, (2017) used the vossiacupidata as a phytoremediator forthe remediation of metal from the metal contaminated water bodies [ 144 ]. Saran et al, (2020) investigated the effect of the Helianthus petiolaris plant on the uptake of cadmium and lead metals from metal-pollutedsoil and observedthat it is efficient for less than 50 mg/kg and 1000 mg/kg of cadmium and lead concentration respectively in soil [ 145 ]. Li et al, (2021) investigated the effect of manures and compost fertilizers on halophytic plants for the biosorption of heavy metals ions from agricultural soil and found that fertilizer enhanced the metal extraction efficiency of zinc, copper, cadmium, and lead respectively [ 146 ].…”

“…Based on previous research, the recently described aromatic H. petiolaris was selected [24,25]. The phytomanagement field trial was conducting according to Yang et al (2010) [42], 60 seedlings of H. petiolaris were raised in a greenhouse for a month and then transplanted into the experimental sites.…”

This field study aimed to assess the base line conditions of a long-term polluted shooting range in Argentina polluted with 428 mg kg-1 lead (Pb), to evaluate the establishment and development of Helianthus petiolaris plants and address the efficacy of the phytomanagement strategy through: i) element accumulation in plant tissues; ii) rhizosphere bacterial diversity changes by Illumina Miseq™ and iii) floral water and essential oil yield, composition and element concentration by GC-MS and ICP. After one life cycle growing in the polluted sites, in the roots of Helianthus petiolaris plants Pb concentration was between 195 and 304 mg kg-1 Pb. Only a limited fraction of the Pb was translocated to the aerial parts. The predominance of the genus Serratia in the rhizosphere of Helianthus petiolaris plants cultivated in the polluted sites and the decrees of the essential oil yield were some effects significantly associated with soil Pb concentration. No detectable Pb concentration was found in the floral water and essential oil obtained. Extractable Pb concentration in the soil reduced between 28-45 % after the harvest.

“…The mechanism entails the complexation of metal ions with the roots, or with the cell walls, binding with molecules present in the roots, such as phytochelatins and metallothioneins, and finally sequestering them to root vacuoles [139]. Saran et al [111] studied Helianthus petiolaris to treat soil contaminated with cadmium and lead, and showed that this plant does not interact with the activity of microorganisms already present in the root zone, and is efficient if the soil Cd concentration is lower than 50 mg•kg −1 and the Pb concentration is lower than 1000 mg•kg −1 .…”

Remediation of Metal/Metalloid-Polluted Soils: A Short Review

View full text Add to dashboard Cite

The contamination of soil by heavy metals and metalloids is a worldwide problem due to the accumulation of these compounds in the environment, endangering human health, plants, and animals. Heavy metals and metalloids are normally present in nature, but the rise of industrialization has led to concentrations higher than the admissible ones. They are non-biodegradable and toxic, even at very low concentrations. Residues accumulate in living beings and become dangerous every time they are assimilated and stored faster than they are metabolized. Thus, the potentially harmful effects are due to persistence in the environment, bioaccumulation in the organisms, and toxicity. The severity of the effect depends on the type of heavy metal or metalloid. Indeed, some heavy metals (e.g., Mn, Fe, Co, Ni) at very low concentrations are essential for living organisms, while others (e.g., Cd, Pb, and Hg) are nonessential and are toxic even in trace amounts. It is important to monitor the concentration of heavy metals and metalloids in the environment and adopt methods to remove them. For this purpose, various techniques have been developed over the years: physical remediation (e.g., washing, thermal desorption, solidification), chemical remediation (e.g., adsorption, catalysis, precipitation/solubilization, electrokinetic methods), biological remediation (e.g., biodegradation, phytoremediation, bioventing), and combined remediation (e.g., electrokinetic–microbial remediation; washing–microbial degradation). Some of these are well known and used on a large scale, while others are still at the research level. The main evaluation factors for the choice are contaminated site geology, contamination characteristics, cost, feasibility, and sustainability of the applied process, as well as the technology readiness level. This review aims to give a picture of the main techniques of heavy metal removal, also giving elements to assess their potential hazardousness due to their concentrations.
