Lead (Pb), this ancient element, has left its mark on various facets of history, from ancient Egyptian cosmetics and Roman Empire water pipes to 20th-century car exhausts. Its low cost, softness, and stability have made it highly appealing to humans. Notably, the addition of tetraethyl lead to gasoline significantly enhanced engine performance, a small tweak that was once celebrated as an industrial marvel.
