Antimony poisoning, harmful effects upon body tissues and functions of ingesting or inhaling certain compounds of antimony. Such poisoning resembles arsenic poisoning.

Is antimony harmful to humans?

It has also been listed as a possible human carcinogen by the International Agency for Research on Cancer. Breathing air contaminated with antimony can cause eye and lung irritation, heart and lung damage, stomach pains, diarrhea, vomiting, and stomach ulcers.

Respiratory effects, such as inflammation of the lungs, chronic bronchitis, and chronic emphysema, are the primary effects noted from chronic (long-term) exposure to antimony in humans via inhalation.
