Heavy metals refers to a group of dense metallic elements in the periodic table. These elements have higher atomic weights and densities compared to other metals. Examples include lead, mercury, and cadmium.
Heavy metals often exhibit toxic properties and can have adverse effects on the environment and living organisms due to their persistence and potential for bioaccumulation.
They are a concern in areas such as pollution, environmental chemistry, and industrial processes where their presence may pose risks to human health and ecosystems.
