Heavy metal is actually a broad time period made use of to explain a bunch of naturally developing metallic aspects of large molecular weight and density compared to water.[1] At low concentrations, specific heavy metals, like iron, zinc, copper, and manganese, are essential for human survival but may become poisonous agents at larger concentrations.
Mercury: The commonest source of mercury is methylmercury located in fish secondary to air pollution. Mercury is also an occupational hazard for dentists in international locations wherever the creation of amalgam (filling product for cavities), remains permitted.[6]
