CDPH Lead Inspector/Assessor California State Practice Exam

Which age group is primarily at risk for lead poisoning?

1. Adults over 65 years

2. Children under 6 years

3. School-aged children

4. Pregnant women

The correct answer is: Children under 6 years

The age group primarily at risk for lead poisoning is children under 6 years. This vulnerability is due to several factors: young children's developing bodies and brains are particularly susceptible to the harmful effects of lead. During this critical growth phase, even low levels of lead exposure can lead to significant developmental issues, impacting cognitive abilities, growth, and overall health. Additionally, young children are more likely to be exposed to lead due to behaviors such as hand-to-mouth activity, where they may ingest lead dust or chips from deteriorating lead-based paint or contaminated soil. Their tendency to explore their environment without the caution that older children or adults might exercise further increases their risk. While adults over 65 years, school-aged children, and pregnant women can also be at risk for lead exposure or poisoning, the most critical focus in public health efforts has historically been on children under 6, given the severe consequences of lead toxicity on their health and development. Thus, this age group is prioritized for lead screening and prevention efforts.
