Investigation of the composition of moss, which is a natural bioindicator, for air monitoring in the east Kazakhstan region
Keywords:
Moss-bioindicator, heavy metals, east kazakhstan region, inductively coupled plasma mass spectrometry (icp-ms), reference materials, microwave decomposition method, dry and wet ashingAbstract
Here are 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 the ICP-MS method and the instrumental neutron activation analysis (INAA) method 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
