Estimated Childhood Lead Exposure from Drinking Water in Chicago

The study conducted in Chicago aimed to estimate childhood lead exposure from drinking water, focusing on children under 6 years old. The research utilized machine learning models to predict the risk of lead exposure and identified racial disparities in lead screening and exposure. The results indicated varying levels of lead exposure across different census blocks, with a particular emphasis on the impact on racially minoritized individuals. The study also highlighted the potential health implications of lead exposure, referencing previous research on the cognitive effects of elevated blood lead levels in children. Additionally, the investigation shed light on the prevalence of lead-contaminated drinking water in Chicago and the challenges associated with the removal of lead pipes in the city. The findings underscore the importance of addressing lead exposure in drinking water to safeguard the health and well-being of children, especially in communities facing disparities in screening and exposure rates.
