Envenenamento seguido de morte de pessoas que ingeriram um sulfato de bário preparado em laboratório farmacêutico (em exames de Raios X), foram vítimas de produto contendo alguma porcentagem de carbonato de bário como contaminante. Tratamento por equilíbrio químico dos dados de solubilidade dos precipitados nas condições de acidez estomacal mostrou que a presença do carbonato de bário causa um aumento de solubilidade de 19200 vezes em íons de bário, em comparação com a esperada pelo sulfato de bário puro.Downloads
