What can be a long-term effect of untreated lead poisoning in children?

The long-term effect of untreated lead poisoning in children primarily involves neurological damage. Lead exposure can disrupt normal brain development, resulting in significant cognitive impairments, behavioral issues, and decreased academic performance. It particularly affects areas of the brain responsible for processing information, memory, and concentration, leading to lasting adverse effects on a child's ability to learn and interact socially.

While the other options might suggest positive outcomes, they are inaccurate representations of the consequences of lead poisoning. Enhanced cognitive function, reduced risk of infections, and improved physical growth do not align with the detrimental impacts of lead exposure, which is known to hinder development and lead to health problems later in life. This understanding highlights the critical importance of prevention and early identification of lead exposure in children to support their overall development and well-being.
