Long-term exposure to lead in drinking water can lead to developmental issues in children. What are these issues?

• A. Increased risk of obesity
• B. Delays in physical or mental development
• C. Impaired vision
• D. Reduced immune function

Answer: (B)

Long-term exposure to lead in drinking water is particularly concerning for children as it can result in significant delays in both physical and mental development. Lead is a neurotoxin, and when ingested, it affects the development of the brain and nervous system in young children. This exposure can lead to various developmental disorders, including learning difficulties, decreased IQ, and behavioral issues. Since a child's brain is still developing, even low levels of lead can have lasting effects that hinder their overall development, manifesting in difficulties with attention, memory, and academic achievement. While other choices mention serious health issues, the specific developmental problems associated with lead exposure in children are best captured by the concern over delays in physical and mental development.
