What we’re studying: The main objective is to better understand the relative risks of deteriorated lead paint among various building components and room types, particularly doors and windows, in older affordable housing. NCHH will work with U.S. lead evaluation firms to compile a master database. This database will be used to analyze lead paint content and deterioration on windows and doors and associated floor dust lead loadings. The primary hypothesis is that in dwellings with floor dust lead levels at or above 10 µg/ft2, the percentage of dwellings with deteriorated door lead paint is significantly higher than the percentage of dwellings with deteriorated window lead paint.
Why it matters: This study will help determine whether a large, high-quality housing lead hazard surveillance database can be assembled to investigate pressing questions about the relationships among the presence of lead-based paint, its concentration and condition, and dust lead levels.
Lead evaluation personnel will transmit de-identified XRF, dust wipe, soil, and dwelling characteristics data for 1,000 dwellings to NCHH. NCHH will review the quality of submitted data, compile a master database, and conduct statistical analyses to test the hypothesis. NCHH will conduct several secondary analyses, such as an analysis or porch paint and dust lead levels to identify porch-related factors likely to indicate lead hazards. As data are available, NCHH will also analyze the cause of paint deterioration (e.g., weathering, friction, occupants, impact, moisture) on different housing components, to see how they affect dust lead levels.
This is a new study. We’ll post resources here as they become available.
