Soluble barium compounds have [[LD50]] near 10&nbsp;mg/kg (oral rats).  Symptoms include "convulsions... paralysis of the peripheral nerve system ... severe inflammation of the gastrointestinal tract".<ref name="Ullman2005" />{{rp|18}} The insoluble sulfate is nontoxic and is not classified as a [[dangerous goods]] in transport regulations.<ref name="Ullman2005" />{{rp|9}}
