The content of Fe, Mn, Al, Zn, Ni, Cu, Pb, Cr, Cd and Hg in higher aquatic plants, moss, charophyta and green filamentous algae was determined using inductively coupled plasma emission spectrometry. A comparative assessment of metal accumulation was conducted. Plants growing within the heat-affected zone of Gusinoozersk State Regional Power Plant, especially filamentous algae, contained the largest amount of metals, which indicates the higher pollution of water and sediments and intensification of metabolic processes and their accumulation in plants. It was shown that aquatic plants of Lake Gusinoe accumulated most of the studied metals in volumes greater than in other cooling reservoir of Siberia. Thus, this research provides one of the important steps for the development of regional environmental standards and environmental risk assessments.

Slag Waste

In the context of restrictions due to the sanctions imposed, a key factor in the country's development is the development of new Russian high-tech materials and their production technologies. The study of ash and slag waste from the Kemerovo State District Power Plant was carried out in this work using the methods of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). It has been established that matrix elements make up the predominant share of ash and slag waste. Rare and rare earth elements in terms of their content are classified as trace elements, however, some of them either have commercial values, or are close to it.

In power plant, coal ash obtained by combustion is mixed with river water and transported to the dump. Sequential extraction was used in order to assess pollution caused by leaching of elements during ash transport through the pipeline and in the storage (cassettes). A total of 80 samples of filter ash as well as the ash from active (currently filled) and passive (previously filled) cassettes were studied. Samples were extracted with distilled water, ammonium acetate, ammonium oxalate/oxalic acid, acidic solution of hydrogen-peroxide, and a hydrochloric acid. Concentrations of the several elements (Al, As, Cd, Co, Cu, Cr, Fe, Ba, Ca, Mg, Ni, Pb, and Zn) in all extracts were determined by inductively coupled plasma atomic emission spectrometry. Pattern recognition method was carried out in order to provide better understanding of the nature of distribution of elements according to their origins. Results indicate possible leaching of As, Ca, Cd, Cu, Zn, and Pb. Among these elements As, Cd, and Pb are toxicologically the most important but they were not present in the first two phases with the exception of As. The leaching could be destructive and cause negative effects on plants, water pollution, and damage to some life forms.

Limited liability partnership (LLP) KAZZINC - one of the largest industrial enterprises of East Kazakhstan region. From Kazzinc to the Irtysh water flow should be in the following order: river Filippovka, Quiet, Ulba and the Irtysh. Semey (former Semipalatinsk) is a large city on the Irtysh, the water of which is taken by "SemeyVodokanal" [1]. In the laboratory we investigated the possibility of using filamentous algae (of ulothrix, Spirogyra, cladophora) as biological monitoring in the waters of the Semipalatinsk region. Since the main products of "Kazzinc" LLP are metals such as zinc, cadmium, lead and copper, in the laboratory of elemental analysis of the branch of "Institute of Radiation safety and ecology" of National nuclear center of the Republic of Kazakhstan the absorption capacity of filamentous algae is determined in relation to zinc, copper, cadmium, iron and lead, as well as the residual concentration of heavy metals in the test water. In idle test identifies such elements as Be, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Cd, Cs, Pb, and U. The concentrations of these elements were determined by inductively coupled plasma mass spectrometry (ICP - MS) on the Agilent 7700x instrument and atomic emission spectrometry (NPP - ISP) on the iCAP 6300 Duo.
