Lead

Lead is a bluish-grey, soft, malleable, and heavy metal with a low melting point. It has been used by humans for thousands of years, primarily for making pipes, batteries, and ammunition. Today, it is still widely used in the construction industry, as well as in the production of electronic devices and car batteries.

​

Although lead has many useful properties, it is also highly toxic to humans and animals when ingested or inhaled. Lead poisoning can cause a range of health problems, including developmental delays, neurological damage, and even death. As a result, the use of lead has been regulated and reduced in many countries in recent years, with efforts focused on finding safer alternatives.
