2. Children and pregnant women

3. Older adults

4. Teenagers

The correct answer is: Children and pregnant women

Children and pregnant women are considered the demographic most at risk for lead poisoning due to several key factors. Children, particularly those under the age of six, are particularly vulnerable because their bodies and brains are still developing. They are more likely to engage in hand-to-mouth activities, which can lead to ingestion of lead dust or chips that may be present in their environment, especially in homes with lead-based paint or contaminated soil. Pregnant women are also at heightened risk as lead exposure can affect fetal development. Lead can cross the placenta, potentially leading to adverse outcomes such as low birth weight, preterm birth, and developmental delays in the child. Additionally, lead exposure can negatively impact the mother's health, compounding risks during pregnancy. Understanding these vulnerabilities is crucial for effective lead poisoning prevention strategies, ensuring that both children and pregnant women are protected from exposure in environments where lead is present.
