OSHA PEL: Not Established                                                                                 Animal Toxicity: No Data

ACGIH TLV: Not Established

Effects of Exposure:

Acute: Ingestion: Low toxicity via oral exposure due to poor intestinal absorption.

Skin Contact: None Known

Eye Contact: May cause irritation.

Inhalation: Bromoderma, a bromide rash, often occurs when bromide inhalation or administration is prolonged. This rash is usually found on the face and resembles acne and furunculosis.

Chronic:

Ingestion: None Known                                                                                         Skin Contact: None Known

Eye Contact: None Known                                                                                    Inhalation: None Known

Other: Inorganic bromides may produce depression, emaciation and in severe cases, psychosis and mental deterioration. Rare earth compounds may cause delayed blood clotting leading to hemorrhages.
