Potential health effects

Target Organs: skin, eyes, mucous membranes, upper respiratory system, gastrointestinal (GI) tract

Principle Routes of Exposure

inhalation, ingestion Acute Effects Inhalation: The dust may be discomforting to the upper respiratory tract. Persons with impaired respiratory function, airway diseases, and conditions such as emphysema or chronic bronchitis may incur further disability if excessive concentrations of particulate are inhaled. Eye: The material is moderately discomforting to the eyes and is capable of causing a mild, temporary redness of the conjunctiva (similar to wind-burn), temporary impairment of vision and/or other transient eye damage/ulceration. Skin: The material is moderately discomforting to the skin. Solution of material in moisture on the skin or in perspiration may increase irritant effects. Open cuts, abraded or irritated skin should not be exposed to this material. Ingestion: The material is moderately discomforting to the gastrointestinal tract and may be harmful if swallowed in large quantity. Copyright © 2006 by Genium Group, Inc.

Ingestion can cause irritation of the gastrointestinal tract and purging. Diarrhea may occur from ingestion of large quantities. In treatment of cyanide poisoning, 12.5 gm. has been injected intravenously without ill-effect. Thiosulfate salts are poorly absorbed from the alimentary tract and as a consequence act as an osmotic cathartic. Absorbed thiosulfates are remarkably inert and are distributed in extracellular fluids where they may cause osmotic disturbances. Carcinogenicity NTP - Not listed; IARC - Not listed;
