What is lead?

Lead is a type of metal. Although it forms in ore in small amounts deep underground, lead is abundant and easy to mine.

Lead used to be a common ingredient in many consumer products in the United States, from gasoline and paint to cosmetics and pipes. But it’s highly toxic, so it’s now regulated to minimize or eliminate the amount of lead people are exposed to. Despite regulation, lead is still problematic in certain communities and workplaces.
