Heavy metals are metallic chemical elements that have a high density and are toxic at low concentrations. This group of elements includes substances such as lead, mercury, cadmium, arsenic, and chromium, among others. Heavy metals are commonly found in the environment as a result of human activities such as industrial processes, mining, and agriculture. They can accumulate in soil, water, and air, posing a significant risk to human health and the environment. Research in the area of heavy metals focuses on understanding the sources, distribution, and behavior of these elements in the environment, as well as their effects on living organisms. This includes studying the mechanisms of heavy metal toxicity, bioaccumulation, and biomagnification in food chains. Researchers also investigate methods for detecting and monitoring heavy metal contamination, as well as developing strategies for remediation and mitigation of heavy metal pollution. Overall, research in this area aims to protect human health and the environment from the harmful effects of heavy metal exposure.
