ABSTRACT
Heavy metal contamination is an issue related to regions of intensified industry. Heavy metal–polluted groundwater is a genuine worry in most nations. The effect of heavy metals on aquatic organisms is due to the development of contamination from different diffuse or point sources, which frequently combine in unforeseen ways in the ecosystem. Heavy metals enter plant, animal, and human tissues through breathing, diet, and manual handling. Some heavy metals are also potent carcinogens and have a tendency to accumulate in biological systems. Heavy metals have harmful consequences for soil microorganisms, consequently resulting in change to various qualities, population size, and general action of the soil microbial groups. Heavy metal contaminants in aquatic systems stimulate the creation of reactive oxygen species, which can harm fish and other oceanic life. The raised level of heavy metals in the groundwater represents a considerable hazard to users of nearby resources and possibly to the common habitat.
