Pb

Pb is the chemical symbol for lead, a heavy metal traditionally used in products like paint, pipes, and gasoline. It’s known for its durability and low cost but can be toxic to humans and animals if ingested or inhaled as dust or fumes. Lead exposure can cause health problems, especially in children, affecting brain development and causing other neurological and health issues. Due to these risks, many countries have regulations limiting lead use. While modern applications have decreased, lead remains in some older infrastructure and products, so handling and disposal require caution.
