Metal fume fever is most strongly associated with inhalation of fumes of which element?

• A. Zinc
• B. Copper
• C. Lead
• D. Mercury

Answer: (A)

Metal fume fever is a transient febrile illness caused by inhaling metal oxide fumes produced when metals are heated, especially zinc-containing metals. The strongest association is with zinc oxide fumes because inhalation of these aerosols triggers an inflammatory, cytokine-driven response in the lungs that produces flu-like symptoms—fever, chills, malaise, cough, and myalgia—after a few hours of exposure and typically resolves within 24–48 hours after exposure ends. This classic link to zinc oxide explains why zinc is the correct choice.

Exposures to other metals can cause respiratory irritation or systemic effects, but they don’t produce the characteristic metal fume fever picture as reliably. Lead exposure leads more often to anemia and neurological or gastrointestinal symptoms, mercury exposure can cause tremor and neurotoxicity, and copper fumes can irritate the airways but are less strongly associated with the specific febrile syndrome seen with zinc oxide.
