Which sampling criterion relates to lead in paint chips?

• A. Paint Chip Sampling Criteria
• B. Soil Sampling Criteria
• C. Dust Sampling Criteria
• D. Air Sampling Criteria

Answer: (C)

Lead hazards from painted surfaces are best understood by looking at the dust that comes from those surfaces. When paint chips and flaking paint shed particles, they become part of indoor dust. Measuring lead in this dust provides a practical and reliable indication of exposure risk to occupants, especially children who may ingest settled dust. Dust sampling (often using wipe samples on floors and window sills) captures the actual contamination people can be exposed to, not just the presence of lead pigment in a chip. Testing paint chips themselves could tell you whether the chips contain lead, but it doesn’t reflect how much lead people are exposed to through dust generated by those chips. Soil sampling is more about outdoor contamination and is less directly tied to interior exposure from chipped paint. Air sampling looks at airborne particles, which is less typical for routine residential lead hazard assessment unless there’s a specific high-emission situation. So, the sampling criterion that relates to lead in paint chips in this context is dust sampling criteria.
