A Little Background on Lead
Lead (Pb) is a heavy metal that occurs naturally in the Earth's crust. It is soft, malleable, and has a low melting point, making it useful for a variety of applications. Lead has been used for thousands of years in pipes, paint, batteries, and ammunition due to its durability and resistance to corrosion.
However, lead is also highly toxic to humans and animals, particularly affecting the nervous system, kidneys, and blood production. Lead exposure can occur through contaminated water, soil, air, or products like old paint and leaded gasoline (which has been largely phased out in many countries). Children are especially vulnerable to lead poisoning, which can cause developmental and cognitive issues.
