Heavy metal contamination has become a worldwide ecological issue, attracting substantial public attention, largely due to the growing health and environmental issues. Their numerous commercial, residential, rural, health, and technical uses have contributed to their broad environmental dissemination. The following analysis addresses the findings of the various authors past work on Pollution of heavy metals in Buriganga River, together with heavy metals source and its effect of on plant, human and environment all over the world. Concentrations of 8 heavy metals in Buriganga River water and dregs are explored in the analysis to evaluate their levels and compare them with other major Bangladesh rivers. Indiscriminate disposal and redemption of toxic waste into rivers contribute to environmental pollution that might be viewed as a potential source of impendence to the biotic community. Although certain are important, a significant number of trace elements might be noxious to all embodied soul at a severe level because of the advancement of complex mixes inside the cell. Introduction to heavy metals is related to mental hindrance, kidney harm, numerous maladies, and even mortality in occurrences of extremely high exposure.
