On the evidence of the earlier research findings, as well as the full-scale and lab-scale test data of 2019–2020, this article describes the ecological situation at Kara-Keche lignite field being developed by five mining companies in the Jumgal district of the Naryn Region in the Kyrgyz Republic. It is found that the field development proceeds with insufficient adherence to legal documents and has a considerable adverse influence on the environment and water bodies. Many large-volume refuse dumps have no isolation from natural water bodies, which ends with acute pollution of the latter. Contam ...More
Рассмотрены актуальные геоэкологические проблемы, связанные с деятельностью горнодобывающих предприятий Кыргызской Республики. Авторами сделан вывод, что почти все горнодобывающие предприятия оказывают опасное экологическое воздействие на окружающую среду. Необходимо уделять пристальное внимание не только хвостохранилищам, но и отвалам пустых пород, так как они могут иметь громадные объемы и служить опасными источниками химического загрязнения вод в течение длительного времени после закрытия предприятий. -

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
