doctor screening child for lead poisoningChildhood 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.

What data are available?

Maine tracks the following measures associated with childhood lead poisoning:

  • Lead Poisoning
  • Blood Lead Testing (screening)
  • Risk Factors (pre-1950 housing and poverty)

Lead Poisoning

These displays present information on the estimated number and percent of children with a confirmed blood lead test ≥5 μg/dL. Under Maine law, lead poisoning is defined as a blood lead level of 5 μg/dL or higher. Estimated numbers and percents are calculated from total number of children with confirmed blood lead test ≥5 μg/dL plus 38% of children with unconfirmed tests 5-<10 μg/dL. The conversion factor of 38% is based on the historically observed percent of unconfirmed test results of 5-<10 μg/dL that have a confirmatory venous test result ≥5 μg/dL.
