Abstract

The article presents the results of determining the chemical composition of moss in the East Kazakhstan region. The following research stages were carried out: harvesting plant materials; methods of taking samples of the studied material for analysis; determination of the concentration of elements by inductively coupled plasma mass spectrometry (ICP-MS). Developed methods for dry and wet ashing bioindicator. The results of the analysis of moss obtained by ICP-MS and the method of instrumental neutron activation analysis (INAA) are compared. The reliability of the results of the analysis by the method of additives and photometric determination of the concentration of elements was determined.

KEYWORDS: moss-bioindicator, heavy metals, East Kazakhstan region, inductively coupled plasma mass spectrometry (ICP-MS), reference materials, microwave decomposition, dry and wet ashing.
