Lead exposure can cause permanent damage to which organs or systems?

• A. Liver, Pancreas
• B. Heart, Lungs
• C. Brain, Nervous System, Kidneys
• D. Muscles, Bones

Answer: (C)

Leading exposure can permanently damage the brain and nervous system, and the kidneys. Lead is highly toxic to the nervous system, and in children even low levels can cause irreversible cognitive and developmental harm, with lasting effects on learning and behavior. In adults, it can impair memory and concentration and also cause lasting kidney damage from long-term exposure. Because these organs (brain, nervous system, and kidneys) are the primary targets for permanent injury, this option best captures the systems most at risk. The other organ groups may be affected by high exposures, but they are not the ones typically associated with irreversible damage at typical lead exposure levels.
