Chronic poisoning due to lead is known as :

  • A.Plumbism
  • B.Hydrargyrism
  • C.Ptyalism
  • D.Arsenicosis

Answer: A

Chronic lead poisoning is called plumbism.

The name comes from the Latin plumbum, lead. Chronic lead poisoning, also called saturnism, causes a blue line on the gums (Burton's line), colic, anaemia with basophilic stippling of red cells, wrist drop and foot drop, and encephalopathy, especially in children.

The other terms belong to other conditions. Hydrargyrism is chronic mercury poisoning (from hydrargyrum), ptyalism is excessive salivation, a sign of mercury poisoning, and arsenicosis is chronic arsenic poisoning.
