Abstract

Heavy metals are used in a wide range of industries, agriculture, food processing, and domestic applications. Metals are unusual among industrial and environmental contaminants in that they are not generated or damaged by humans, but rather transported and changed into a variety of goods. The purpose of this review study is to look at the varied effects of heavy metals on aquatic organisms. Polluted locations that receive effluents from industrial, agricultural, municipal, and household garbage. Fe > Zn > Cu > Mn > Cd > Pb > Cr > Ni > Hg > As were the metals in order of abundance. The majority of research concluded that important metals (Zn, Fe, Mn , and Cu,) are abundant in aquatic species, whereas non-essential metals are few. Fish and aquatic creatures are utilized as bio-monitoring species in heavy metal contamination, according to this review. Such research, both in relations of human health and the assessment of metal contamination in aquatic environments, should be ongoing.
