RECLEAN Pilot Study

This is an exposure assessment pilot study tailored for families of construction workers living with a child. The investigators will compare home dust metal levels and resident's blood metal levels before and after an educational and environmental intervention. A baseline and a post intervention period assessment will be conducted with home and car lead inspections and risk assessments with collection of dust, urine, blood and toenail samples and a survey. Objectives of this research are to: 1. To characterize pre-intervention home exposures to lead and other metals in households with one construction worker inhabitant living with a child, by assessing household members' biospecimens and home dust metal levels. 2. To develop and evaluate customized home interventions (including environmental and educational approaches) to reduce metals exposure in three tiers of intervention. 3. To characterize home exposures to lead and other metals post intervention and determine adapted behaviors and whether the degree of metals exposure reduction (including take home exposures) in the households depends on the level of intervention.
