Metal pollution refers to the presence of toxic metals in the environment, typically as a result of human activities such as mining, industrial processes, and improper disposal of waste. These metals can accumulate in soil, water, and air, posing a threat to human health and the environment. Research in this area typically focuses on understanding the sources, distribution, and effects of metal pollution, as well as developing strategies for remediation and prevention. This may involve studying the bioavailability and toxicity of metals, monitoring metal concentrations in different environmental compartments, and developing innovative technologies for metal removal and treatment. Metal pollution is a major environmental concern worldwide, and research in this area is essential for protecting ecosystems and human health.
