Itai-Itai disease is due to the toxicity of

  • A.Lead
  • B.Cadmium
  • C.Strontium
  • D.Tin

Answer: B

Itai-itai disease is due to Cadmium.

Itai-itai ('it hurts, it hurts') disease broke out in the Jinzu river basin of Japan, where mining waste polluted rice fields with cadmium. Long exposure softened the bones and damaged the kidneys, causing severe pain and fractures.

Lead poisoning causes plumbism and nerve damage, and mercury, not tin or strontium, caused Japan's other famous disease, Minamata disease.
