Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What percentage of elevated blood lead levels can be found in private housing?

1. 50%

2. 83%

3. 67%

4. 75%

The correct answer is: 83%

The correct choice indicates that 83% of elevated blood lead levels can be found in private housing, highlighting a significant relationship between older residential units and lead exposure. This statistic reflects findings that many homes, particularly those built before lead-based paint was banned in 1978, often harbor lead hazards. In the context of lead exposure risks, it's crucial to understand that elevated blood lead levels are primarily associated with exposure pathways found in older homes, where deteriorating paint, lead dust, and contaminated soil may be present. The statistic emphasizes the importance of inspecting and remediating lead hazards in residential environments to protect public health, especially among vulnerable populations such as children. The other options reflect lower percentages, which do not align with the substantial body of research illustrating the prevalence of lead exposure in residential settings, thus underscoring the importance of awareness and proactive measures in private housing contexts.
