Lead in Soil
Lead-contaminated soil continues to be a hazardous source of lead exposure for young children in the United States. Deposits from leaded gasoline, exterior lead-based paint, and industrial sources have contributed to increased levels of lead in the soil. This is especially common in urban areas and homes built before 1978.
How children may be exposed

- Children can be exposed to lead in soil by swallowing or breathing in lead-contaminated soil while playing.
- Lead-contaminated soil particles can also be brought inside as lead dust or on shoes, clothing, or pets.
- Young children tend to put their hands, which may be contaminated with lead dust from soil, into their mouths.
- Some young children eat soil (this is called pica). Children may also be exposed to lead by eating fruits and vegetables grown in or near lead-contaminated soil.
Get your child tested for lead exposure
If you think that your child has been exposed to lead in soil contact your child’s health care provider. Most children who are exposed to lead have no symptoms. The best way to tell if your child has been exposed is with a blood lead test. Your health care provider can help you decide whether a blood lead test is needed and can also recommend appropriate follow-up actions if your child has been exposed. As levels of lead in the blood increase, adverse effects from lead may also increase.
Reduce or eliminate exposure to lead in soil
- Take off shoes when entering the house to prevent bringing lead-contaminated soil in from outside.
- Prevent children from playing in bare soil. If possible, provide them with sandboxes. Cover sandboxes when not in use to prevent cats from using it as a litter box.
- Plant grass on areas of bare soil or cover the soil with grass seed, mulch, or wood chips, if possible. Until the bare soil is covered, move play areas away from bare soil and away from the sides of the house.
- Do not grow fruits or vegetables in lead-contaminated soil. Using a container garden is a good alternative.
Risk from lead in artificial turf
The risk for harmful lead exposure is low from new fields with elevated lead levels in their turf fibers. This is because the turf fibers are still intact and the lead is unlikely to be available for harmful exposures to occur. As the turf ages and weathers, lead is released in dust that could then be ingested or inhaled, and the risk for harmful exposure increases. If exposures do occur, CDC currently does not know how much lead the body will absorb.
Some artificial turf playing fields may also contain potentially unhealthy levels of lead dust. Artificial turf made of nylon or nylon/polyethylene blend fibers contains levels of lead that pose a potential public health concern. Tests of artificial turf fields made with only polyethylene fibers showed that these fields contained very low levels of lead.
Fields that are old, that are used frequently, and that are exposed to the weather break down into dust as the turf fibers are worn or show signs of weathering, including fibers that are abraded, faded or broken. These factors should be considered when evaluating the potential for harmful lead exposures from a given field.
