EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by ingestion.

Effects of short-term exposure
Ingestion could cause effects on the gastrointestinal tract and nervous system. Ingestion could cause hair loss. Ingestion of large amounts could cause death. The effects may be delayed. Medical observation is indicated. See Notes.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction): 0.02 mg/m³, as TWA; (skin)

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately.

NOTES
The symptoms of neurological disorders do not become manifest until after a few days. Depending on the degree of exposure, periodic medical examination is suggested. Thallium metal is usually kept under mineral oil or an argon atmosphere. Thallium salts may have different toxicological properties. See ICSCs 0336 and 1221.
