Identifying lead hazards in the home is the first step in assessing the risk of lead exposure. The most common sources of lead in older homes are lead-based paint and lead-contaminated dust and soil. Homes built before 1978 are more likely to have lead-based paint, which can deteriorate over time and create lead dust. Lead-contaminated soil can come from sources such as nearby industrial sites, highways, and lead-based paint that has chipped off of homes.
The CDC recommends that homeowners and renters visually inspect their homes for deteriorated paint, dust, and soil. They also recommend hiring a professional to conduct a lead inspection if the home was built before 1978 and has not been previously inspected. A lead inspection will identify the presence of lead-based paint and lead hazards in the home.
Testing for Lead in Environmental Samples
Testing for lead in environmental samples is the second step in assessing the risk of lead exposure. The most common way to test for lead exposure is through a blood lead test. A blood lead test measures the amount of lead in the bloodstream and is the most reliable way to determine if a person has been exposed to lead.
Environmental samples, such as dust and soil, can also be tested for lead. The EPA recommends testing for lead in soil if the home is located near a lead-emitting industry, a major highway, or a lead-contaminated site. Dust can also be tested for lead, especially in areas where children play or spend a lot of time.
In conclusion, identifying lead hazards in the home and testing for lead in environmental samples are important steps in assessing the risk of lead exposure. Homeowners and renters should take steps to protect their families from lead exposure by visually inspecting their homes, hiring a professional to conduct a lead inspection, and testing for lead in environmental samples.
