简要总结
The objective of this study is to assess the effectiveness of portable air filtration (PAF) for mitigating lead dust exposures and reducing childhood blood lead levels in older housing.
详细描述
In close collaboration with local health departments, this project will enroll 40 participants who (1) reside in housing built before 1970, and (2) have children under six years of age with blood lead levels (BLL) >5 μg/dL. Specific objectives include (1) assess reduction of Pb dust exposure via the intervention, (2) assess the ability of PAF to reduce childhood BLL indirectly via reductions in Pb dust exposure, and (3) develop evidence-based exposure reduction guidance for wider public use of PAF. The project team will measure Pb levels in (1) suspended dust, (2) floor dust, and (3) children's blood before the start and finish of the two-month-long intervention as well as at the midpoint.
