Which statement is NOT listed as a reason wipe sampling is recommended?

• A. It is relatively simple and cheap.
• B. Yields more accurate results than any other method.
• C. It has been correlated with children's blood lead levels in studies.
• D. Current standards are based on wipe sampling.

Answer: (B)

Wipe sampling is recommended because it provides a practical, low-cost way to assess surface lead contamination that is closely tied to real exposure. It’s relatively simple and inexpensive to perform, making it feasible for routine use. Studies have shown that wipe lead levels correlate with children’s blood lead levels, which supports using this method as a proxy for potential health risk. Standards and regulatory guidelines are also built around wipe sampling, reinforcing its role in the monitoring framework. The statement that wipe sampling yields more accurate results than any other method is not listed because no single method is deemed universally the most accurate; wipe sampling offers practicality and a proven link to exposure, while other methods may be better suited for different objectives or contexts.
