Abstract There are numerous barium compounds the toxicity of which is largely a function of their solubility. For this reason, barium oxide, nitrate and chloride are the most toxic. Barium salts are used in a variety of industrial applications. Barium sulfate, which is insoluble, is still occasionally used as a contrasting agent in radiology. Soluble barium salts are rapidly absorbed and eliminated. They are toxic for the heart and the nervous system. In cases of acute poisoning, digestive disorders are observed, but heart disorders are the most frequent, including harmful effects on excitability and conduction, aggravated by hypokalaemia that is a characteristic of barium poisoning. Oral administration of magnesium sulfate enables the precipitation of soluble barium salts.
