The radionuclides content in the leaves of the Asteraceae family plants

Abstract

Background. The study of natural and artificial radionuclides behavior is becoming increasingly important due to their extraction and redistribution with minerals, nuclear testing and industrial, radiation accidents and disasters [1]. Materials and methods. The studies were carried out on the basis of the Ecology Department of the Institute of Natural Sciences and Pharmacy of the Mari State University. The objects of the study were the leaves of common tansy (Tanacetum vulgare L.), common yarrow (Achillea millefolium L.), common dandelion (Taraxacum officinale, Wigg. s. L.), coltsfoot (Tussilago farfara, L.), common mugwort (Artemisia vulgaris L.), collected in the Republic of Mari El (urban-type settlement Sovetsky, Yoshkar-Ola city) and in the Khanty-Mansiysk Autonomous Okrug – Yugra (Langepas city). It was studied the accumulation and distribution of radionuclides of natural and technogenic origin. Results. During the study, it was found that the highest content of 137Cs present in the leaves of plants growing on the territory of Yoshkar-Ola. The maximum amount of 137Cs was found in the leaves of common tansy. The largest amount of 90Sr was found in leaves of dandelion officinalis and wormwood, growing in Sovetsky. A high content of 40K was found in the leaves of wormwood and tansy, growing on the territory of Sovetsky and in coltsfoot growing in Langepas. Conclusions. Based on the results of study, it found that natural and technogenic radionuclides are actively accumulated in plants of the Asteraceae family.
