What is lead?

Lead is a naturally occurring metal in the environment. Lead can be found in the air, soil, water, and inside our homes.

Lead-based paint and lead dust are the main sources of lead poisoning. Homes built before 1978 are likely to have lead-based paint.

Other sources could include soil, drinking water, toys and jewelry, workplace and hobby hazards, aluminum or glazed ceramic cookware, imported spices, and traditional home remedies and cosmetics. Learn more about common sources of lead.
