What are the effects in children due to lead exposure?

• A. Reduced IQ, learning disabilities.
• B. Kidney damage, hypertension.
• C. Toxic accumulation of lead in the body.
• D. Lead-based paint.

Answer: (A)

Lead exposure in children mainly affects the developing brain, causing cognitive and behavioral problems. Even low levels can interfere with brain development, leading to lower IQ scores and learning disabilities, along with attention and behavior issues that can impact school performance. This is why describing reduced IQ and learning disabilities best captures the typical pediatric outcomes of lead exposure.

Kidney damage and hypertension are more commonly associated with chronic exposure in adults, not the primary pediatric outcomes. Toxic accumulation describes how lead builds up in the body, not the effects themselves, and lead-based paint is a source of exposure rather than an effect.
