“…The following approach employs soil electro-kinetic remediation, which is successful in low-permeability soil and creates an electric field gradient on both sides of the electro-lytic tank containing the contaminated soil (Kamari, 2011;Sabatini and Knox, 1992). Another method includes cleaning contaminated soil with specific chemicals to remove HMs complexes and dissolved iron from solid-phase particles (Su, 2014;El-Nagar and Abdel-Halim, 2021;Wu et al, 2023;Mukherjee et al, 2021;Islam et al, 2022a;Mathur et al, 2022;Sharma et al, 2021;Sodhi et al, 2022). The last approach is clay mineral fixing and adsorption, such as zeolite, bentonite, etc.…”

Heavy metals (HMs) are harmful and lethal at negligible levels and non-biodegradable in the typical ecosystem and constitutes animal, human and environmental hazards. They are divided into toxic metals like Lead, Cadmium, Arsenic, etc. and essential elements like copper, zinc, manganese, iron, nickel and chromium. Additionally, could be categorized into two groups based on the natural and anthropogenic sources releasing origins. Population and industrial expansion led to food contamination with HMs. Poisonous metals can be transferred from irrigation water to agricultural soils, agricultural operations, air pollution, animal feed, and packaging materials. Toxic metals are non-biodegradable, non-thermos degradable, and exceedingly stable in the ecosystem; as a result, they quickly build in various foods. Metal pollution of many foods, including agricultural commodities, and animal protein sources such as fish, milk, meat, and eggs, poses a hazard to food safety and security. Toxic metal pollution of irrigation water, agricultural soils, plants, and animals result in their integration into the food chain, posing a health hazard to humans. Most metals are harmful to animals and humans and accumulate in several organs like the skeleton, hepatic tissue, spleen, and renal tissues. Metals have a deleterious impact on the production of plants and animals. As a result, several remediation strategies have become necessary to limit the hazardous HMs pathway into the food chain and the human body. Metal nanoparticles are employed in beneficial applications, although they are associated with specific hazards.
