To the Question of Ecological Purity of Lichens Samples Used as Bioactive Raw Material for Biotechnological Processing

Smagulova A.Sh., Anshakova V.V. 

Because the thallus of the lichen genus Cladonia is a valuable raw material for series of biological products used in medicine and food industry, we performed analysis on the content of a number of toxic and biogenic elements and also 137Cs  and  90Sr radionuclides in lichen samples taken from different areas of the Republic of Sakha (Yakutia). It is shown that in the lichens gathering locations (for subsequent biotechnological processing) the content of toxic heavy metals and radionuclides is tens times below the maximum allowable concentration for these elements in foods.


Key words: lichen thalli, heavy metals, radionuclides.
