Lead
What is Lead?
Lead is a naturally occurring heavy metal found in small amounts within the earth’s crust and used extensively throughout modern industry. Its durability, density, and low melting point made it a common ingredient in older paints, plumbing systems, solder, ceramics, and various consumer products. While useful, lead becomes hazardous when inhaled or ingested—especially in dust or chips from deteriorating lead-based paint—posing significant health risks to children and adults. Understanding where lead may be present is essential for safe renovation, testing, and long-term protection of indoor environments.
