Lead in its pure form has a metallic gray color, but when freshly cut it can have a slight hint of blue.
Lead was first discovered in the Middle East (Asia Minor) between 7,000 and 6,500 BCE based on metallic lead beads discovered by archeologists. These metallic lead beads also represent some of the first examples of metal smelting.

You know that wooden pencil that you think contains lead? Guess what, it doesn’t, it contains graphite.
Lead is very poisonous to humans and when inhaled or swallowed it will affect every part of the human body.
The Flint water crisis is the most notorious case of lead in drinking water. Flint, a city in Michigan didn’t apply corrosion inhibitors to the water they sourced from the Flint River. This allowed lead from aging pipes to leach into the water supply and expose more than 100,000 residents to high levels of lead.
