What else do we need to know besides lead paint concentration?

• A. Condition of paint; various exposure pathways; likely sources of exposure; future plans for dwelling
• B. Color of paint
• C. Age of the occupants
• D. Exterior cleanliness

Answer: (A)

Lead exposure risk comes from more than just how much lead is in the paint. To assess the real hazard, you need to know the condition of the painted surfaces—are they intact or deteriorating, peeling, or chipping? Deteriorated paint can generate dust and chips that people may ingest or inhale, especially children. You also have to map out exposure pathways—how lead could reach people in the home. This includes inhaling lead-containing dust, ingesting dust or soil, and any activities that could disturb paint and create new exposure routes, such as sanding or remodeling. Consider likely sources of exposure inside and around the dwelling—where lead dust could originate (peeling paint on walls, windows, doors, or deteriorated finishes; lead-contaminated soil from outdoor areas; dust tracked in from outside). Finally, future plans for the dwelling matter—renovations, remodeling, or changes in occupancy that could disturb painted surfaces or increase contact with lead-containing dust or chips. All of this provides a fuller picture of risk than concentration alone, which is why this option is the best choice. The other factors listed (paint color, occupants’ age, exterior cleanliness) don’t by themselves inform the exposure risk in the same comprehensive way.
