What is a long-term health effect of welding fumes overexposure?

• A. Siderosis (iron deposits in lung)
• B. Dizziness
• C. Nausea
• D. Temporary numbness

Answer: (A)

Inhaling welding fumes over a long period leads to deposition of metal particles in the lungs, especially iron oxide from iron-containing fumes. This accumulation results in siderosis, a condition reflecting chronic exposure where iron deposits can appear in lung tissue and on imaging. That makes siderosis the characteristic long-term health effect of welding fume overexposure. The other symptoms—dizziness, nausea, and temporary numbness—are more typical of short-term, immediate reactions to fumes (acute exposure) rather than lasting lung changes.
