title: Dissolution of silicic acid from dusts of kaolin, mica and talc and its relation to their hemolytic activity. -- an in vitro study.
abstract: Hemolysis induced by native kaolin dust was found to run parallel to the amount of silicic acid dissolved from it. Native mica and talc dusts were hemolytic only to a small extent and the silicic acid dissolution from these dusts was also smaller in comparison to that of native kaolin. The proportionality between hemolysis and the amount of dissolved silicic acid was not consistently observed in the case of acid, alkali and water treated kaolin, mica and talc dusts.
