Area of Science:

  • Pediatrics
  • Environmental Health
  • Toxicology

Background:

  • Lead intoxication poses significant risks to young children's development.
  • Mandatory lead screening in Massachusetts identifies a notable number of infants with elevated lead levels.

Purpose of the Study:

  • To analyze the characteristics and sources of lead intoxication in infants under 12 months.
  • To compare infant lead exposure origins with those in older children (18-30 months).

Main Methods:

  • Retrospective review of 50 infants (≤12 months) in a lead referral program.
  • Comparison with 47 toddlers (18-30 months) from the same program.
  • Analysis of lead levels, erythrocyte protoporphyrin, and identified exposure sources.

Main Results:

  • Infants presented with a mean peak lead level of 39.0 µg/dL.
  • Common infant exposure sources included household renovation (20), paint chips (10), and contaminated water (9).
  • Toddlers primarily ingested paint chips (41) or were exposed during renovation (2).

Conclusions:

  • Infant lead intoxication is prevalent and stems from different sources than in toddlers.
  • Environmental factors like renovation and contaminated water are key infant exposure routes.
  • Understanding these distinct origins is vital for targeted prevention strategies in infants.
