Which element is associated with Minamata disease (mercury poisoning)?

• A. Mercury
• B. Lead
• C. Cadmium
• D. Arsenic

Answer: (A)

Minamata disease is classic mercury poisoning. It arose from industrial discharge containing methylmercury into water, which bioaccumulated in fish and shellfish people ate. Methylmercury is a powerful neurotoxin, especially dangerous for developing fetuses, leading to severe neurological effects in infants and speech, motor, and sensory impairments in adults. While other heavy metals like lead, cadmium, and arsenic cause their own distinct toxicities, the illness named Minamata disease is specifically tied to mercury exposure.
