Heavy metal is a term given to a division of metals and metalloids that are differentiated by high atomic weight and specific density, five times higher to water or greater than 4000 kg/m³ (Hashim et al. 2011; Kura et al. 2018). Heavy metals are toxic even at deficient concentrations and harmful to human health (Madhav et al. 2020). The following heavy metals are addressed as geogenic pollutants in this chapter.
