Which sampling method is used to assess lead-based paint hazards?

• A. Air sampling
• B. Paint chip sample
• C. Soil sampling
• D. Water sampling

Answer: (B)

The key idea is to directly determine whether the painted surfaces themselves contain lead. Collecting paint chips from suspect surfaces and analyzing them for lead content shows if the paint layer is hazardous. Air sampling, soil sampling, and water sampling each assess other exposure pathways or environmental contamination, not whether the paint on the surfaces contains lead. Paint chip sampling provides the specific evidence needed to confirm lead-based paint hazards in the painted surfaces.
