CDPH Lead Inspector/Assessor California State Practice Exam

What is typically not analyzed as part of a risk assessment?

1. Soil

2. Water

3. Air

4. Dust

The correct answer is: Air

In the context of lead risk assessments, air quality is typically not a primary focus of analysis. Risk assessments are designed to evaluate potential exposure to lead hazards in environments where people live, work, or spend significant time. The primary concern is the exposure to lead in materials that are more densely concentrated and likely to be encountered directly, such as paint, dust, soil, and sometimes water. Dust is a significant aspect of risk assessments because it can contain lead particles from deteriorating lead-based paint or contaminated soil. Similarly, soil is analyzed for lead contamination, especially in areas near old structures or in urban settings where leaded gasoline was once prevalent. Water quality is also assessed, particularly in homes with lead plumbing or where the water supply may be contaminated by lead sources. While air quality is important in overall environmental health assessments, the presence of lead in the air is typically lower and less direct when compared to other mediums. Therefore, it does not form a core part of lead risk assessment protocols focusing on direct exposure pathways.
