Lead is a naturally occurring metal. It has been used for thousands of years for a wide variety of purposes, including as a paint additive. There are three reasons why lead has been used in paint. The first reason is that lead is very resistant to corrosive substances like acid. The second reason is that lead, when combined with other materials to form compounds, produces vibrant and lasting paint colors. The third reason is leads abundance. Its extensive availability makes it a much cheaper alternative than other substances that have similar properties. Despite its useful properties, lead is a potent narrow toxin that has severe and permanent damaging effects on the human body. Even a single chip of lead containing paint can contain enough lead to cause serious health problems.
