Who is particularly vulnerable to lead exposure?

Children under six years old are particularly vulnerable to lead exposure due to several physiological and developmental factors. During early childhood, their brains and bodies are still developing, making them more susceptible to the neurotoxic effects of lead. This age group has a higher rate of lead absorption compared to adults, as their bodies are still growing and they often engage in behaviors, such as hand-to-mouth activities, that increase the likelihood of ingesting lead dust or paint chips.

Additionally, children tend to have higher exposure levels because they spend more time on the ground and often place toys and other objects in their mouths, which can easily become contaminated with lead. The potential harmful effects of lead exposure during this critical time of development can lead to serious cognitive and behavioral issues that may have lasting impacts into adulthood.

While other groups, such as adults over 65, teenagers, and pregnant women, also face risks related to lead exposure, children under six years are categorized as the most vulnerable because the impacts can be far more detrimental to their developing systems. This is why targeting lead safety and prevention efforts towards younger children is crucial.
