Lead, a toxic metal found in the Earth’s crust, has contaminated the planet through mining, smelting, manufacturing, and recycling.
Despite known dangers, some countries still use leaded paint and aviation fuel.
Over 75% of lead is used in vehicle batteries, while traces persist in paints, glassware, toys, and cosmetics.
Lead pipes and solder also contaminate drinking water.
Children suffer irreversible brain and nerve damage, while adults face organ and reproductive risks.
In 2021, lead exposure caused 1.5 million deaths—half among children under five.
