Technogenic impact assessment on the environment of Pavlodar region using GIS technologies

Abstract

Pavlodar region is the largest industrial center of Kazakhstan. There are three cities with developed industries in the region: Pavlodar, Ekibastuz, and Aksu. A diversified industrial complex has developed in the region, which is focused on the production of electricity, alumina, oil products, mechanical engineering, the food industry, and building materials. The consequences of the rapid development of industry in the Pavlodar region were the highest rate of emissions of pollutants into the atmosphere in the Republic of Kazakhstan. According to the observations of environmentalists, the state of the atmospheric air in the region has deteriorated since the 1990s. Air pollution in industrial cities has a detrimental effect not only on human life, but also on animals, plants, and microorganisms, and also damages the economy of the region. Enormous damage to the waters of the Irtysh is caused by the enterprises of Pavlodar, as well as many enterprises of the East Kazakhstan region, the territory of which flows through most of the Irtysh River. Another no less significant environmental problem is the chemical pollution of the city of Pavlodar with mercury, associated with the Pavlodar chemical plant. Thus, one of the main tasks of the region is to improve the environmental situation.

Spatial Distribution of PM2.5 and Pm10 Pollutants in Residential Area of Pavlodar, Kazakhstan

“…The results of the analysis of the air quality correlate with the conclusions published in the Information bulletin on the state of the environment of the Republic of Kazakhstan for September 2023 (Kazhydromet, 2003) that the level of air pollution in Pavlodar is increased. The results of the study are also consistent with previously published works (Kakabayev et al, 2023;Lukyanets et al, 2023). For example, the annual average level of PM2.5 exceeds the WHO recommended limit (10 µg m -3 , (WHO, 2006)) in six out of seven monitoring stations.…”

“…Thus, Tatayeva et al (Tatayeva & Burumbayeva, 2014) analyzes air pollution in Pavlodar and other cities in Kazakhstan, highlighting the impact of pollutants on lung cancer incidence. Kakabayev et al (Kakabayev et al, 2023) discusses the consequences of industrial development in Pavlodar, including high emissions of pollutants into the atmosphere and the need to improve the environmental situation. Mardenov et al (Mardenov et al, 2014) focuses on the atmospheric air condition in Ekibastuz, a city in Pavlodar region, emphasizing the negative influence of power engineering and metallurgic industry on air quality.…”

Digital Visualization of Environmental Risk Indicators in the Territory of the Urban Industrial Zone

“…The northern industrial zone of Pavlodar City is a pronounced example of an urbanized and industrial-developed territory [55,56]. It is a multisectoral complex devoted to the production of electricity and fuel-based energy, oil refining, the production of chemicals and construction materials, machine building, and light and food industries [57,58]. It also contains mercury-storing ponds, used earlier for the electrochemical production of Kaustik soda with a liquid mercury cathode.…”
