11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: May cause irritation
on the eye: May cause irritation
Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Cesium compounds may cause hyper-irritability, including spasms,
dizziness, abdominal cramps, vomiting, diarrhea, convulsions and
collapse. Chronic ingestion of cesium has been fatal to laboratory
animals, possibly due to the replacement of potassium. Chronic
exposure also can have blood and neuromuscular effects.
