Subacute to chronic toxicity:
Tungsten compounds may be irritating to the eyes and respiratory tract. Animal studies suggest that soluble tungsten compounds have the potential for causing adverse health effects involving the gastrointestinal tract and central nervous system. These effects have not been observed in humans. Chronic exposure to tungsten compounds may result in permanent lung damage.
Cesium compounds may cause hyperirritability including spasms. Chronic ingestion of
cesium has been fatal to laboratory animals.
Subacute to chronic toxicity:
No effects known.
