Hazardous Consequences and Management of Heavy Metals in Sewage Sludge: An Overview

Abstract: Natural substances called heavy metals (HMs) can build up in the environment over time and are dangerous even in small amounts, posing a danger to the ecosystem and human health. Certain metals can infiltrate the wastewater treatment system and eventually accumulate in the sludge produced during the treatment process. Due to its interaction with industrial and household effluents, sludge, a by - product of sewage water treatment, is known to contain significant quantities of toxic metals. Sludge can contain HMs from several sources, such as industrial discharges, domestic wastewater, and agricultural runoff. In this review, the presence of HMs in sludge, and several treatment methods, consisting of physical, chemical, and biological processes have been developed, as have the regulations and guidelines controlling their disposal and usage were discussed. The selection of an appropriate treatment procedure, on the other hand, is dependent on the individual features of the sludge and the target metals. Sludge, if not managed properly, may leach HMs into the environment, damaging water, soil, and food crops. Proper HMs management in sludge is critical for reducing environmental and health concerns and promoting long - term sustainability.
