Lead in drinking water can result in which health effect?

• A. Prostate cancer
• B. Impaired mental function in children
• C. Stomach and intestinal disorders
• D. Reduced white blood count

Answer: (B)

Lead exposure from drinking water primarily threatens children's brain development. Lead is a powerful neurotoxin, and in developing minds it can disrupt how nerve cells grow, form connections, and communicate. Even low levels of exposure in early life are linked to lower IQ, attention difficulties, learning problems, and behavior issues that can last for years. That strong and well-documented impact on cognitive and behavioral development makes impaired mental function in children the most relevant health effect of lead in drinking water. Stomach and intestinal issues can occur with very high, acute ingestions of lead, but the typical public health concern with drinking water is the neurodevelopmental risk in kids, not GI symptoms. Prostate cancer isn’t a recognized direct outcome of lead exposure from drinking water, and while lead can contribute to anemia by affecting red blood cell production, a reduced white blood cell count isn’t the hallmark effect.
