[Heavy metals in the mammalian body with special reference to zinc and its methods of detection].

In this study the presence of heavy metals in mammals with special regard of the zinc have been investigated. The methods of the detection of zinc were described too. The current methods for investigating heavy metals ( dithizon -, sulfid -silver- and fluorescence-method) are compared. The use of these methods is discussed. The occurrence of the heavy metals in tissues of various species is demonstrated. Metabolic functions of heavy metals are explained. The important role of zinc-ions in the storage of hormones and other substances as well as the importance of cobaltous-ions for the degranulation of mast cells are referred too.
