This study is to characterize and compare the short and long-term efficacy of full lead-paint abatement and less costly Repair and Maintenance (R&M) interventions for reducing lead in settled house dust (PbD) and children's blood. This research is important because dusts and residential paints are major sources of exposure in U.S. children, particularly those living in houses with deteriorating paint and elevated PbD levels. The R&M approach may provide a practical and cost-effective means of reducing exposure for future generations of children who will continue to occupy lead-painted housing. In this study, three levels of R&M interventions are being tested in 75 older dwellings, with 15 modern and 15 previously abated dwellings serving as controls. EPA funding is anticipated to measure lead in dust, soil, water, and children's blood over a 2-year period of followup. This paper describes the design and status of this ongoing study as of March, 1994.
