Why track childhood lead poisoning?

Lead has been banned in most consumer goods for decades, but old lead paint is still found in many of Maine's older homes, making it a persistent  health threat. Tracking lead poisoning data and risk factors such as age of housing and poverty levels allow us to identify areas in need of public health interventions and evaluate prevention efforts.
