Specific target organ system toxicity - repeated exposure: No effects known.

Specific target organ system toxicity - single exposure: No effects known.

Aspiration hazard: No effects known.

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.

Rhenium compounds may be irritating to the eyes and respiratory tract.

Subacute to chronic toxicity: No effects known.

Additional toxicological information: To the best of our knowledge the acute and chronic toxicity of this

substance is not fully known.
