危化品

Physical Description | Barium chlorate appears as a white crystalline solid. Forms very flammable mixtures with combustible materials. Mixtures may be ignited by friction and may be explosive if the combustible material is finely divided. Contact with concentrated sulfuric acid solutions may cause fires or explosions. May spontaneously decompose and ignite when mixed with ammonium salt. May explode under prolonged exposure to heat or fire. Used in explosives and pyrotechnics, in dyeing textiles, and to make other chlorates.

Toxicity

ICSC Environmental Data

The substance is harmful to aquatic organisms.

Probable Routes of Human Exposure

... POISONING MAY RESULT WHEN WORKERS ARE EXPOSED TO ATMOSPHERIC CONCN OF THE DUST OF SOL CMPD AS MAY OCCUR DURING GRINDING.

Symptoms

Ingesting excess barium may cause vomiting, abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, numbness around the face, and muscle weakness. High levels may result in changes in heart rhythm or paralysis and possibly death. (L214)

Treatment

Intravenous infusion of potassium often relieves many of the symptoms of barium toxicity. (L214)

Health Effects

The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. (L214)

Adverse Effects

ACGIH Carcinogen - Not Classifiable.

Exposure Routes

Oral (L214); inhalation (L214)

Toxicity Summary

Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. (L214)

Minimum Risk Level

Intermediate Oral: 0.2 mg/kg/day (L134) Chronic Oral: 0.2 mg/kg/day (L134)

Human Toxicity Excerpts

/SIGNS AND SYMPTOMS/ Symptoms are: cyanosis, gastric pain, brachycardia. Death occurs by paralysis of the heart or of the respiratory system.

Carcinogen Classification

No indication of carcinogenicity to humans (not listed by IARC).

Evidence for Carcinogenicity
