It has been established that the main pollutant is dust containing elevated concentrations of heavy metal compounds, which is removed from the surface of tailings dumps by air flows. The spatial and temporal patterns of the distribution of the pollutants in the atmospheric air are revealed. It has been experimentally proved that contamination of the air basin with heavy metal compounds, sulfate ion aerosols, and dust is extremely high.

It was shown that the OHC rate of natural waters was not an indicator of water pollution unlike with industrial wastewater. It was emphasized that this indicator of natural water determines the background concentration of organohalogen compounds, which was not a constant value, since it was caused by many biotic and abiotic factors.","PeriodicalId":11462,"journal":{"name":"Ecology and Industry of Russia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49600939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
