Ecological Assessment of the Current State of Environmental Components on the Territory of the Impact of Ccement Production Industry

Abstract

The monitoring of the environmental components condition, exposed to the influence of the cement production enterprises, was the aim of the conducted research. One of the largest cement production factories in Russia, where the territory of negative impact has a total area of over 300 square kilometers, was the object of the study. The observations of the dust content in atmospheric air, as well as the determination of degradation degree of vegetation in the area of influence of the considered production facility were conducted. Chemical and granulometric composition of the cement dust, which is emitted in atmospheric air, were identified in the laboratory. Mapping model, which indicates the complex ecological welfare of the territory, exposed to the cement production industry, was compiled by the authors on the basis of the data, obtained in conducted research. The mapping model takes into account both the content of dust in near-ground atmosphere, and the extent of its deposition to soil, vegetation and surface water bodies.

Assessment and abatement of the eco-risk caused by mine spoils in the dry subtropical climate

“…The resulting dumps are characterized by several adverse environmental features, such as dusting with a lack of moisture, compaction, and relatively low content of organic substances. The dust blown away from dump sites poses a threat when it (i) enters human respiratory tracts; (ii) absorbs pollutants in the atmospheric air, which subsequently settle in the topsoil layer causing the rise of pollution rate on farmsteads; and (iii) migrates with the water runoff from land surface to water bodies (Moiseenko et al, 2018), affecting urbanized areas (Cheremisina et al, 2017;Hełdak & Bykowa, 2017;Strizhenok & Ivanov, 2017;Tabatabaee Moradi & Nikolaev, 2018). Thus, the annually published Federal Reports on the State and Protection of the Environment in the Russian Federation state that the cement production industry is a major pollution source in a number of cities.…”

Transformation of the chemical properties of soils in the zone of influence of the asphalt concrete plant

“…However, the demand for asphalt mix in the region sometimes exceeds the production capacity of both stationary and mobile asphalt-concrete plants. At the same time, the high cost of transporting raw materials and finished products, as well as the need for a large number of workers, are increasingly forcing industrial enterprises producing construction materials to locate their facilities within settlements or in their immediate vicinity [4]. Polluting components in the form of dust settle on the soil surface, penetrate through the thickness into deeper horizons, leading to a decrease (30-40% coverage) of the projective vegetation cover.…”

Economic effect calculation from new flaxseed solution for road dust suppression during open pit mining in Alexeevsky cement deposit in Mordovia: Case study

“…Mining operations are not only time-consuming but have a side effect connected with utilization of technical waste [5]. Cement production is a process with high load to the environment, especially air [6]. An urgent problem is to enhance energy and ecological efficiency of the mines [7]; [8].…”
