How does exposure to vanadium typically manifest in individuals?

Exposure to vanadium typically manifests in individuals through the characteristic symptom of a green tongue. This appears due to the formation of vanadium compounds that can result in pigmentation changes in the oral cavity, particularly affecting the tongue. The green coloration is a notable clinical finding and serves as an important indicator for identifying vanadium exposure.

In addition to the green tongue, individuals exposed to vanadium may experience other symptoms, but the distinct coloration makes this symptom particularly relevant in industrial hygiene and toxicology contexts. Coughing, dermatitis, and asthma attacks may be associated with other exposures or conditions, but the green tongue is specifically linked to vanadium exposure, highlighting the unique effects it can have on health.
