Children are affected differently and more severely by lead exposure from batteries compared to adults due to several physiological and behavioral factors:
- Higher Absorption Rates: Children absorb a larger proportion of ingested lead than adults. Their bodies take in lead more efficiently from the gastrointestinal tract, leading to higher internal doses even if the external exposure level is the same.
- Smaller Body Size and Developing Systems: Because children have smaller bodies, the same amount of lead results in a higher dose relative to body weight. Their developing organs and nervous systems are more vulnerable to lead’s toxic effects, particularly the brain.
- Behavioral Factors: Children are more likely to ingest lead-contaminated dust or soil because of hand-to-mouth behaviors common in infants and toddlers, increasing their exposure risks.
- Neurodevelopmental Impact: Lead exposure in children, including prenatal exposure through maternal transfer, has been linked to significant neurobehavioral development issues. These effects are more profound and long-lasting than in adults, affecting cognition, attention, and behavior.
- Exposure from Lead-Acid Batteries: Informal recycling of used lead-acid batteries (ULABs), often found near homes and schools in low- and middle-income countries, is a major source of lead exposure for children. These activities release lead dust and fumes into the environment, posing a serious risk to children who live or attend school nearby.
In summary, children’s greater lead absorption, smaller body size, developing neurological systems, and behaviors lead to more severe health consequences from lead exposure from batteries than adults experience.
