What is Lead?

Lead is a highly toxic metal found in small amounts in the earth’s crust. Because of its abundance, low cost, and physical properties, lead and lead compounds have been used in a wide variety of products including paint, ceramics, pipes, solders, gasoline, batteries, and cosmetics. Since 1980, federal and state regulatory standards have helped to minimize or eliminate the amount of lead in consumer products and occupational settings. Today, the most common sources of lead exposure in the United States are lead-based paint in older homes, contaminated soil, household dust and drinking water.

Today at least 4 million households have children living in them that are being exposed to lead. There are approximately half a million U.S. children ages 1-5 with blood lead levels above 10 micrograms per deciliter (µg/dL)


  • CDC lowered the recommended blood lead action level for lead exposure in children to10 µg/dL in 1991.
  • States may have their own levels of concern for adults and children.
  • Most states have reporting systems for lead poisoning.
  • OSHA has set required standards for the amount of lead allowed in workroom air at 50 µg/m3 averaged over an 8-hour workday.
  • EPA has set a standard for lead in the ambient air of 0.15 µg/m3 averaged over a calendar quarter.
  • EPA has established 400 ppm for lead in bare soils in play areas and 1200 ppm for non-play areas for federally funded projects. This may be used as a guidance level elsewhere.
  • EPA’s action level for lead in water delivered to users of public drinking water systems is 15 µg/L. Its goal for lead is zero.
  • FDA has set various action levels regarding lead in food items. Use of lead-soldered food cans is now banned.
  • Today, paint intended for residential use is limited to 0.06% lead content.
