Lead-based hazards are most concerning for which population?

• A. Infants and young children
• B. Adults
• C. Pets
• D. Elderly

Answer: (A)

Lead exposure affects developing nervous systems much more in young children than in adults. Infants and toddlers are especially vulnerable because their bodies absorb lead more efficiently relative to their size, and their behaviors—hand-to-mouth activity and playing close to dust and soil—increase their chances of ingesting lead found in old paint, contaminated soil, or household dust. Even low levels of exposure can cause lasting harm, including cognitive deficits, lower IQ, learning and behavioral problems, speech and language delays, and growth issues. While adults can suffer health effects from lead too, the impact on young children is far more severe and has lifelong consequences, which is why they are the population of greatest concern.
