PSD Track 1: Session III- Lead Exposure and Remediation

Childhood Lead Exposure Pathways

Using data collected from 345 homes (429 children) in Michigan from 2017–2021, NCHH explored routes of childhood lead exposure using repeated measures pathways models. Data collected included lead in blood, paint, dust, soil, water, and other housing, demographic, and behavioral metrics. This presentation will present insights from the findings as well as observations about exposure pathways from research by NCHH and other sources.

Evaluating the Long-Term Effectiveness of Residential Lead Remediation

Session

Description: Despite efforts to mitigate lead exposures, children continue to be exposed to lead; these exposures result in adverse health outcomes over the life course. Because there is no safe blood lead level, residential lead remediation is an effective primary and secondary prevention approach for lead poisoning. However, the long-term effectiveness of residential lead remediation has not been described. We present preliminary data to assess the long-term effectiveness of residential lead remediation and share some of the experiences recruiting homes into the study. Fifty- six homes were enrolled into the study and a lead risk assessment conducted. Based on the risk assessment reports, we characterized homes as being lead safe or lead unsafe. The preliminary data show that homes remediated more than 13 years ago are lead unsafe.
