Элементный Состав Твердой Фазы Снегового Покрова Малых Населенных Пунктов (На Примере Села Долонь Восточно-Казахстанской Области, Республика Казахстан)

Background: Thermal power facilities using coal are in the first place in terms of emissions. From the burning of coal, about 2,100 tons/year of copper (Cu) falls to the Earth's surface annually. Prolonged inhalation intake of Cu into the human body as part of solid particles of atmospheric air from coal-fired boilers leads to accumulation of trace elements in tissues, the development of hyperelementosis. Aim: to identify the level of Cu accumulation in the hair of the population of the administrative center of the Altai Republic in relation to the content of trace elements in solid particles of snow cover. Methods: In 122 residents permanently residing in Gorno-Altaysk, the Cu content in the hair was determined in compliance with the necessary exclusion criteria. In the districts of 10 coal-fired boiler houses of the city, snow samples were taken for analysis for the content of Cu in snow water and solid snow particles. The concentration of Cu in the studied samples was determined by atomic absorption method (Kvant-2, Russia). The Mann - Whitney criterion and Spearman correlation coefficient were used for statistical analysis. Results: the Cu content in the hair of the examined does not depend on gender (U = 1741; p = 0.580), at the age of 4-21 years, the Cu concentration decreases (U = 29; p = 0.05). The concentration of Cu in the hair of residents of Gorno-Altaysk, compared with other regions of the world, corresponds to low values (10.0 mg / kg), hypo- (7.5 mg / kg 31.9%) is more common among the population than hyperelementosis (25 mg / kg - 5.7%). The Cu content in meltwater from all snow intakes in the areas of coal-fired boilers (0.019-0.049 mg / l) does not exceed the permissible concentration (MPC 0.1 mg / l). In the solid phases of snow from 10 samples (19.37-67.42 mg/kg), only three (56.4-67.2 mg/ kg) showed a slight excess of MPC (55 mg/ kg). No correlation was found between the concentration of Cu in the hair of the population and the content of trace elements in solid particles of snow. Conclusions: The assumption about the accumulation of Cu in the hair of the population of Gorno-Altaysk in elevated concentrations, inhalation intake of trace elements from coal boilers was not confirmed in this study.

Studies on thermal power plant areas with respect to chemical composition of particulate matter deposited in snow cover are limited. This study aims to monitor (2014–2022) particulate load and trace elements associated with the particulate matter distributed around (0.5-4.5 km) the coal-fired thermal power plant in Karaganda. In this study, snow cover was used as an effective scavenger of atmospheric pollutants. Using instrumental neutron activation analysis and atomic absorption spectrometry, the content of 26 elements and Hg, respectively, was determined in the particulate phase of snow. The results showed that particulate load varied from 26 to 1751, with mean of 427 and a background of 47 mg m-2 d-1. Anthropogenic impact caused a significant increase in content of U, Hg, Ta, Zn, Na, Cr, Co, Sr, Rb, Cs, Sc, Ca, Fe, Nd, Ba (2–30 times) in the samples compared to the background. Metal-bearing phases of Zn, Ba, As, U-Ta-Nb were detected through scanning electron microscope. The highest levels of particulate load (169–1032 mg m-2 d-1) and element contents in the samples were localized up to 0.7 km from the thermal power plant. The changes of particulate load and element composition of snow deposits during the monitoring period were connected with temperature, modernization of dust-collecting equipment, composition of coal and fly ash, long-range transport of emissions from other industries. The element content and metal-bearing phases in the particulate phase of snow can be used as markers for identifying emission sources from coal combustion.
