Heavy metal pollution continues to be a serious problem in the environment due to uncontrolled pesticide use, mining, foundry operations, smelting, fossil fuel burning and sewage sludge dumping. Mercury, lead, chromium, cadmium, copper and other heavy metals are non-biodegradable and remain in the environment in regions where human activity is prevalent. Heavy metal contamination is a serious hazard to all biota in the ecosystem because of its devastating consequences and their accumulation in soil and water has significant implications for food safety and security, the growth of plants and the survival of soil microorganisms that play significant roles in sustaining agricultural crop production. Even at low doses, these metals are toxic and can affect the food chain, posing serious public health risks. Hence, the purpose of this study is to present a concise but detailed potential source and impacts of heavy metals on the biotic segment of the ecosystems with a view to understanding and building long-term strategies for reducing their pollution and protecting public health.
