Lead is a metal that occurs naturally in the earth's crust, but human activity — mining, burning fossil fuels and manufacturing — has caused it to become more widespread. Lead was also once a key ingredient in paint and gasoline and is still used in batteries, solder, pipes, pottery, roofing materials and some cosmetics.
Lead in paint-Lead-based paint is still on walls and woodwork in many older homes and apartments. Most lead poisoning in children results from eating lead-based paint chips.
Water pipes and imported canned goods-Lead pipes, brass plumbing fixtures and copper pipes soldered with lead can release lead particles into tap water. Although lead solder in food cans is banned in the United States, it's still used in some countries.
Lead can also sometimes be found in:
Soil. Lead particles that settle on the soil from leaded gasoline or paint can last for years. Lead-contaminated soil is still a major problem around highways and in some urban settings. Soil close to walls of older houses may contain lead.
Water. Copper plumbing soldered with lead is a source of contamination of household drinking water.
Household dust. Household dust can contain lead from lead paint chips or from contaminated soil brought in from outside.
Pottery. Glazes found on some ceramics, china and porcelain can contain lead that may leach into food.
Toys. Lead is sometimes found in toys and other products produced abroad.
Traditional cosmetics. Kohl is a traditional cosmetic, often used as eyeliner. Testing of various samples of kohl has revealed high levels of lead.
