Mercury exposure is classically associated with Pink disease.

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

Answer: (A)

Pink disease, also known as acrodynia, is a pediatric mercurial poisoning syndrome. It is classically linked to mercury exposure because chronic mercury exposure in children—historically from calomel-containing teething powders or other mercury-bearing preparations—produces a distinctive presentation: irritability, excessive sweating, tachycardia, photophobia, swelling and pink discoloration of the cheeks (hence the name), and later peeling of the skin. This strong association with mercury sets it apart from other metals, whose toxic effects present differently (for example, lead with anemia and Burton lines on the gums, cadmium with kidney damage, arsenic with GI symptoms). So the correct association is mercury exposure.
