Prediction of the formation of low-molecular components, particles, and condensed phases during thermal destruction of oil-contaminated soil

Kubat KEMELOV | Zarlık MAYMEKOV

In this study, thermodynamic modelling of the process of thermal destruction of oil-contaminated soil of Ozenmunaigas JSC, which includes compounds such as carbon, silicon, aluminum, iron, calcium, magnesium, sodium, potassium, chromium, phosphorus, manganese, copper, titanium, molybdenum, nickel, vanadium, and water, was carried out. The physicochemical and thermodynamic parameters of the complex system were calculated at P0.1 MPa, T598-3000 K. The concentration distribution of components, particles, and condensed phases in the gas phase has been established. In the process of thermal destruc ...More

Ecological Assessment of Technogenically Disturbed Soils of the Mountain Ecosystems of Kyrgyz Republic Based on the TRIAD Method

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Aygül USUBALİYEVA | Ciyde TOKPAEVA

Comprehensive studies of soil contamination were performed in the area of settlement Kichi-Kemin (Kyrgyz Republic). Soils of the Kyrgyz Republic are exposed to waste (tailings) of many industrial enterprises of the mining industry not far from the village of A k-Tuz, located 145 km from the capital of Kyrgyz Republic, Bishkek, at an altitude of 2300 m above sea level. It is noted that 4.17 million tons of radioactive waste from one of the enterprises were once disposed of at four tailings in the Kichi-Kemin Valley. The main waste elements are radioactive thorium, heavy metals such as cadmium, ...More

A Comparison of Various Ecological Indexes for Environmental Assessment of Vulnerable Mountain Ecosystems

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Gülbübü KURMANBEKOVA | Ciyde TOKPAEVA

The aim of this work was to compare various ecological indexes to assess the state of urbanized ecosystems of the Issyk-Kul region in the Kyrgyz Republic. Soil samples were analyzed for Pb, Zn, Fe, Cu and Cd using AAS. Heavy metal contamination status was assessed using indexes for enrichment factor, geo accumulation, contamination factor, degree of contamination, pollution load, potential ecological risk and integrated risk using the Triad approach. Results show marked variations of heavy metal concentrations within the study area. The concentrations of heavy metals in soils of Issyk-Kul had ...More
