11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Irritating effect.
Sensitization: No sensitizing 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.
