Sources of Lead

Childhood Lead Poisoning Prevention Program Logo - click to go to homepageLead in Paint

Lead-based paint is a common source of lead contamination. Lead paint was widely used in homes up until the 1950s and was not banned for residential use until 1978. Lead paint is still found in many older homes today.
Lead paint in poor condition contaminates the home as it falls apart or deteriorates. Lead paint chips and lead dust are created when there is:

  • Chipping, peeling, cracking, or deteriorated lead-based paint

  • Abrasion, scraping, or friction of lead-based paint

  • Disturbance of lead-based paint during maintenance, renovation, or remodeling

Lead in Dust

Lead can contaminate household dust when lead-based paint is deteriorated or disturbed. Lead dust can collect in windowsills, troughs, floors, carpets, furniture, and ventilation filters. It can also get on children's hands, toys, bottles, and pacifier. Frequent house cleaning and hand washing can help prevent children from swallowing or breathing in lead dust.

Lead in Soil

The soil around a house, garage or fence could be contaminated by lead paint or industrial pollution. Lead in soil can be a hazard when children play in bare soil or when people bring soil into the house on their shoes.

Lead in Drinking Water

Lead can enter drinking water when plumbing materials that contain lead corrode. The most common sources of lead in drinking water are lead pipes, faucets, and fixtures. The only way to know whether your tap water contains lead is to have it tested.

  • Abatement and cleanup of residential and commercial buildings, steel structures, or environmental sites

  • Demolition of buildings and structures built before 1978

  • Fabrication of artistic or individual products (e.g., mixing or applying leaded ceramic glaze, glasswork, and stain glass windows)

  • Manufacturing of products containing or coated with lead (e.g., metal equipment parts, batteries, bullets, circuits)

  • Melting of products containing lead (e.g., secondary smelting [scrap metal], incinerators, foundries/casting)

  • Industrial mineral processing activities, such as mining, extraction, or smelting

  • Painting or sanding on industrial equipment and steel structures (e.g., bridges and water towers)

  • Recycling materials (e.g., stripping electronics)

  • Repair, renovation, remodeling, and/or painting of residential and commercial buildings

  • Use of firearms or working at a firing range (e.g., law enforcement, military, private industry, and training)

  • Welding and cutting (small scale melting)

  • Auto repairers (car parts may contain lead)

  • Battery manufacturers (batteries contain lead)

  • Lead miners, refiners, and smelters

Lead in Toys, Jewelry, and Recalled Products

Toys made in other countries and older painted toys passed down through generations are more likely to contain lead paint. Other items that can contain lead include keys, children's jewelry, some imported plastic mini-blinds, and other imported products.

Lead in Glazed Pottery and Ceramics

Lead can be present in some antique or imported glazed ceramics, pottery, and dishware. Avoid using imported pottery, dishware, and ceramics for storing or cooking food and drinks if you don't know if it contains lead. Some imported pottery labeled lead-free may still contain lead.
