The most abundant transition metal in the human body and arguably the most consequential metal in biology. Iron sits at the center of a paradox that drives pathology across virtually every disease domain: organisms need it for oxygen transport, energy metabolism, DNA sy…

An essential macromineral required as a cofactor for over 300 enzymatic reactions in the body, including energy metabolism, protein synthesis, DNA/RNA stability, and neuromuscular function. Magnesium is not a heavy metal or trace element but is frequently measured along…
Mercury is the most toxic heavy metal with no known biological function. Its organic form -- methylmercury (MeHg) -- is the primary concern for dietary exposure via fish consumption. Mercury's toxicity centers on thiol group binding, glutathione depletion, and blood-bra…
A transition metal occupying a central position in this wiki's evidence base. Nickel is toxic and carcinogenic to humans, yet an essential cofactor for pathogen virulence enzymes. It is the most frequent contact allergen worldwide and drives a wide spectrum of systemic …
An essential trace element that is primarily protective in its biological roles. Unlike most metals in this wiki, selenium's toxicological significance lies more in the consequences of its deficiency than its excess. Selenium is the backbone of the selenoproteome -- a f…
