Application of wood biochar in polluted soils stabilized the toxic metals and enhanced wheat (Triticum aestivum) growth and soil enzymatic activity

Thallium contamination in agricultural soils and associated potential remediation via biochar utilization

“…Specifically, biochar plays a prominent function in limiting Tl leachability and other natural pollution in soils at some point in the adsorption technique. Due to the sufficient pore shape of biochar, Tl can migrate from the outer sphere to the internal sphere of the adsorbent (Wang et al 2018a, b) because it contains a significant number of sorption houses primarily based on its negative surface charge, bulk density, and surface area (Ali et al 2019). For example, the abundance of negatively charged surface sites on biochars because of the presence of functional groups such as carboxyl, hydroxyl, and phenolic (-COO − and -OH − ) can bind Tl cationic as a toxic metal and thereby decrease its mobility in soil (Shaheen et al 2019).…”

Nanoscale Zero-Valent Iron Has Minimum Toxicological Risk on the Germination and Early Growth of Two Grass Species with Potential for Phytostabilization

“…Some of the adverse effects caused by soil contamination can be decreased by chemical stabilization, which implies the addition of materials to soil to decrease the mobility and bioavailability of metallic and metalloid contaminants [1,2]. In past years, engineered nanoparticles (ENP), materials with at least two dimensions between 1 and 100 nm, have played a role in newly developed remediation technologies [3][4][5].…”

“…Hence, species that are tolerant to high contamination levels and, at the same time, present an extensive fasciculated root system, rapid growth and establishment, high longevity, easy maintenance, good adaptation to contamination and below-ground accumulation of metals are the best candidates for phytostabilization [14][15][16]. The selection of the appropriate amendment or combination of amendments is also crucial for the success of the remediation process [1,14,17]. The interactions between the selected amendment and plant species and the subsequent relationship with the target contaminants will condition the restoration process.…”

“…A positive response of these interactions in terms of soil restoration may help phytostabilization to being successfully assisted by the amendment. Therefore, the understanding of such interactions has recently gained substantial attention [1,[18][19][20].…”
