Which organization developed standards addressing the collection, preparation, and analysis of paint samples for lead determination?

• A. National Institute of Standards and Technology (NIST)
• B. American Society of Testing Materials (ASTM)
• C. World Health Organization (WHO)
• D. Environmental Protection Agency (EPA)

Answer: (D)

Standards for collecting, preparing, and analyzing paint samples for lead determination come from the Environmental Protection Agency because these procedures are part of how the U.S. regulates and mitigates lead-based paint hazards. The EPA publishes methods and guidelines, such as those in SW-846, that specify how to sample painted surfaces (where to collect chips, how many samples, avoiding contamination), how to prepare those samples for analysis (drying, grinding, digestion), and how to analyze them for lead content (field methods like XRF and laboratory methods like ICP-OES or AAS). These standards also include QA/QC, chain-of-custody, and interpretation criteria used to decide whether a surface exceeds regulatory limits and requires action. While NIST provides measurement standards and ASTM offers many testing standards, the EPA is the agency that directly develops and enforces lead-in-paint sampling and analysis protocols in the U.S. and is the best fit for this context.
