Subacute to chronic toxicity:
Barium compounds may cause severe gastroenteritis, including abdominal pain, vomiting and diarrhea, tremors, faintness, paralysis of the arms and legs, and slow
or irregular heartbeat. Severe cases may produce collapse and death due to respiratory failure. Soluble barium compounds are more likely to cause these effects
than insoluble compounds. Inhalation of fumes may cause sore throat, coughing, labored breathing, and irritation of the respiratory tract as well as the above
symptoms.
Subacute to chronic toxicity: No effects known.
Subacute to chronic toxicity:
Exposure to nitrites may cause nausea, vomiting, cyanosis, and collapse into a coma. Small doses cause a fall in blood pressure, rapid pulse, muscle weakness,
headache and visual disturbances.
Additional toxicological information: To the best of our knowledge the acute and chronic toxicity of this substance is not fully known.
