Which age group has the highest incidence of lead poisoning?

The highest incidence of lead poisoning occurs in toddlers primarily due to their developmental stage and behavior. Toddlers are typically more curious and exploratory, which leads them to engage in activities such as putting objects in their mouths, increasing the likelihood of lead exposure from contaminated surfaces or materials. Additionally, their bodies absorb lead more readily than those of older children and adults, making them more vulnerable to its harmful effects.

In homes built before 1978, when lead-based paints were commonly used, young children may touch surfaces and inadvertently ingest lead dust or chips. Given the importance of this developmental phase in terms of growth and brain development, even low levels of lead exposure can have significant impacts on cognitive and physical development, reinforcing the focus on toddlers as the most susceptible age group for lead poisoning.
