DETERMINATION OF TOXIC, ESSENTIAL AND RELATIVELY ESSENTIAL ELEMENTS LEVEL IN ALPACA HAIR WITH USING OF DIFFERENT SAMPLING TYPES

Abstract

The method of inductive coupled plasma mass spectrometry (ICP-MS) was used for elemental analysis of alpaca hair. Various methods impact of hair sampling for analysis was evaluated with using deionized water and acetone. Sodium content decrease in the in hair samples washed with deionized water and Mg, Li, V, Ag, Cd, Ba level decrease in samples treated with acetone were found. The results can be explained by sodium attendance in the hair in the form of simple cations that are not bound to any organic compounds by strong bonds, while the results obtained for Mg, Li, V, Ag, Cd, Ba, suggest that the ions of these elements are connected with structural hair formations. Significant differences in the content of other macro- and microelements in alpaca hair treated with deionized water and acetone were not found.
