Zinc Carbonate: Chemical Water Contaminants: Medicinal Use and Potential Health Risks and Cleanup
Zinc Carbonate Zinc Carbonate has the formula ZnCO3 and is an inorganic substance. It is a white solid that is water-insoluble. Smithsonite is a mineral that can be found in nature. It's made by adding potassium bicarbonate to cold zinc sulphate solutions. It transforms to a basic z inc spar (Zn5(CO3)2(OH)6) when heated. The structure of z inc spar is similar to that of calcium carbonate. Zinc is octahedral, and each carbonate is bound to six Zn centres, resulting in three-coordinate oxygen atoms. Medicinal Use Highly insoluble zinc oxide and Zinc Carbonate are applied freely to irritated skin in the form of powder, calamine lotion, and other products. Antiseptic, astringent, and caustic characteristics of zinc chloride, sulphate, and acetate have all been used. The difficulty of local control, not systemic effects, limits their utility. An oral dose of 1000 or 2000 mg of zinc sulphate in a glass of water has been used as an emetic. This amount purposely...
