What is a common material tested for lead in residential buildings?

• A. Glass
• B. Wood
• C. Plastic
• D. Concrete

Answer: (B)

In residential buildings, wood is a common material tested for lead because it often serves as a substrate for paint products that may contain lead. Historically, lead-based paints were widely used in homes, particularly those built before 1978 when the U.S. banned their use for residential properties due to health concerns associated with lead exposure. Testing wood for lead is crucial, especially in locations where layers of paint may have deteriorated, creating lead dust or chips that pose a risk to inhabitants, particularly children. The other materials listed, such as glass, plastic, and concrete, are less commonly associated with lead exposure related to paint. While lead can be found in some industrial applications involving glass and in certain cement mixtures, these are not the typical sources of lead contamination in residential settings under scrutiny for lead paint risk assessment.
