Question

Metal fume fever is a delayed type of disease with flu-like symptoms. It has been associated with exposure to all of the following EXCEPT:

A) Magnesium oxide fumes
B) Nascent zinc oxide fumes
C) Zinc oxide fumes
D) Thorium oxide fumes

Answer 1

Thorium oxide fumes have not been associated with metal fume fever, which is usually caused by exposure to metal oxide fumes from metals like zinc and magnesium.

Step-by-step explanation:

Metal fume fever is an illness that typically results from inhalation of certain metal oxide fumes. The disease is characterized by a delayed reaction leading to flu-like symptoms. Of the options provided—Magnesium oxide fumes (A), Nascent zinc oxide fumes (B), Zinc oxide fumes (C), and Thorium oxide fumes (D)—the one that has not been associated with metal fume fever is D) Thorium oxide fumes.

Metal fume fever typically occurs due to exposure to metal oxide fumes from metals like zinc, magnesium, and cadmium. Thorium oxide, however, is not commonly associated with the flu-like symptoms of metal fume fever.
