About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • child under seven years of age with BLL >5 µg/dL,
  • child must reside in housing built before 1978, and
  • child must sleep at home during participation in the two month-long study.

Exclusion criteria

  • anything in child's health history that could affect the study results, or

Treatment and study plan

portable air filtration systems

Other

Two portable air filtration units placed in subjects' homes (one in child's bedroom and one in living room) will be kept running for two months.

Primary outcomes

  1. Change in blood lead level

    Time frame: After two months at the end of the intervention

    change in blood lead level (in ug/dL).
