Exploring the Synergistic Effects of Heavy Metal contaminants on Aquatic Organisms
Abstract: Human activities have a profound effect on aquatic habitats by altering water and sediment quality, which in turn impacts resident organisms. These changes are primarily caused by pollutants from agricultural, industrial, and health-related sources. Industrial effluents, often containing hazardous heavy metals such as chromium, manganese, and lead, are a major source of environmental toxicity. The discharge of these pollutants makes water unsafe for drinking, irrigation, and industrial uses, necessitating effective …
