Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

Which of the following is true about lead exposure?

1. Lead exposure only occurs from paint

2. Lead can be found in soil and dust

3. Lead is harmless in small amounts

4. Lead exposure has no health effects

The correct answer is: Lead can be found in soil and dust

Lead can indeed be found in soil and dust, making it a significant concern for lead exposure. This is particularly important in urban areas or homes built before 1978, when lead-based paints were commonly used. As paint deteriorates, it can create lead dust or chips that contaminate the surrounding environment. Furthermore, historical uses of lead in various products and activities, such as plumbing, industrial processes, and fuel, indicate that lead can find its way into soil and eroded dust, posing risks to human health, particularly in children who may ingest or inhale lead-contaminated particles. The presence of lead in the environment outside of paint highlights the multifaceted nature of lead exposure risks, extending beyond just paint sources to include dust from renovations, disturbed soil, and old pipes. Understanding this is crucial for risk assessors and public health officials when evaluating lead hazards and implementing protective measures for communities.
