Results indicated that mining soils and organic amendments significantly affected plant growth and yield parameters and potentially toxic elements’ content in spinach. becomes one of the foremost waste utilization and disposal practices, soil is increasingly being seen as a major source of metal(loid)s reaching food chain, largely through plant uptake and animal transfer. Heavy metal buildup in soils is of concern in agricultural production due to the adverse effects on food safety and marketability, crop growth due to phytotoxicity, and environmental health of soil organisms. grown at high iron concentration in nutrient solution. Metal contamination issues are becoming more and more common, in India and elsewhere, with many documented cases of metal toxicity in, mining industries, foundries, smelters, coal-burning power plants, and, agriculture. At vegetative stages, high. This condensed chro-, matin is hypermethylated, leading to silencing of, putative anti-oncogenic gene expression, thus, driving treated cells to a carcinogenic state (, et al.

The term “heavy metals”, refers to any metallic element that has a rela-, tively high density and is toxic or poisonous, even at low concentration (Lenntech Water, metals” in a general collective term, which, applies to the group of metals and metalloids, five times or more, are greater than water, of the heavy metals are the most influencing, factors compared to their density. effect on growth yield and content of Cd, Pb in barley. biological and medical aspects.
