“…For many decades, Kazakhstan has developed a predominantly raw material system of nature management with huge man-made loads on the environment. Environmental protection is one of the most important tasks in any state's development [BELOZUBOVA, ZUBKOVA 2021]. Environmental problems are aggravated by the complex radiation environment.…”

The article deals with the problems of induction of the anatomical and morphological structure of plants of different life forms under the conditions of a long-term chronic action of ionising radiation on the territory of the Northern nuclear power plant. Currently, the study and assessment of the radioecological situation on the territory of the former Semipalatinsk nuclear test site, taking into account the ecological state of natural plant and animal populations, is of particular importance. The study of the reaction of living organisms, be it plants or animals, to different doses of chronic ionising radiation makes it possible to assess and diagnose the state of environmental quality, and these organisms themselves can serve as bioindicators of pollution. On the territory of the Semipalatinsk test site, at the experimental site "Balapan", 3 sections with meadow type of soil were studied: polluted section no. 1 -the northwestern shore of Lake Chagan, polluted section no. 2 -the north-eastern shore of Lake Chagan, and control section no. 3. For structural analysis, the study recorded the vegetative organs of plant species with an increased radiation background. It was found that when the EDR (exposure dose rate) of gamma radiation increases and the plant growth is stimulated. In the conditions of radioactive contamination, with an increase in the activity of alpha, beta and gamma radiation, plants response and changes occur in the internal structure of their vegetative organs. Such adaptive features arise under the influence of a complex of environmental factors, including radiation pollution.

The paper considers the features of arsenic (As) accumulation in the steppe soils of the Samara region (Russia) and its four specially protected natural areas. It has been established that As is one of the most toxic elements and belongs to the first hazard class. The work uses quantitative indicators of As content in the upper humus horizon of steppe soils of the Samara region (in the period from 1991 to 2005). The data on the accumulation and distribution of As in virgin soils of the studied protected areas, obtained in 2023, are analyzed. A relatively high level of As content in the studied soils has been established. The reasons for the active accumulation of As in virgin soils of the steppes are substantiated. It is suggested that the increased content of As in the humus horizon of soils may affect the phytodiversity of virgin steppes.
