Which factor is NOT listed as part of what to know besides lead concentration?

• A. Condition of paint; various exposure pathways; likely sources of exposure; future plans for dwelling
• B. Year the building was constructed
• C. Presence of asbestos
• D. Previous renovations

Answer: (D)

When evaluating lead hazards, you look beyond the numeric lead concentration to understand how people might be exposed in the home. This includes the current condition of painted surfaces (is the paint chipped or dusty?), the routes through which lead could reach occupants (dust, soil, ingestion), and the likely sources of exposure (areas where lead paint is present and disturbed). You also consider future plans for the dwelling, since renovations or changes in use can affect exposure risk and the steps needed to mitigate it. The option about past renovations isn’t part of that information set in this context, so it doesn’t fit with what you need to know besides the lead level. The other factors help you gauge actual risk and plan appropriate actions based on how the home is used and what condition the surfaces are in.
