Sobre IBD

La géophagie, une forme de pica, est la consommation de sols argileux, particulièrement répandue chez les femmes enceintes de Lubumbashi. Um estudo efectuado junto de 450 mulheres revelou uma prevalência de 68%, com um consumo maioritário de caulino (81%), proveniente de várias regiões.L’analyse organoleptique a mis en évidence des caractéristiques distinctives des sols consommés, tandis que les examens physico-chimiques ont révélé la présence d’éléments chimiques tels que SiO₂, Al₂O₃, Fe₂O₃, TiO₂ e K₂O, bem como de metais ácidos (As, Cd, Pb, Ni) e substâncias urânicas. A capacidade de troca catiónica variou de 21,4 a 31,0 méq/100 g, e os sólidos eram ácidos de acordo com o seu pH.Este estudo põe em evidência o carácter corrente da geofagia em Lubumbashi, independentemente das condições sociais. Abre perspectivas para a aplicação de métodos de descontaminação, a fim de explorar estas argilas em farmácia, sem perigo para a saúde.
