Utilization of Construction Waste to Improve Soil Properties on the Thermally Active Dump Ema

Diplomová práce se zaměřuje na možnost využití směsného stavebního odpadu ke zlepšování vlastností půdy na termicky aktivních odvalech důlní hlušiny Ema a Heřmanice. Byly sledovány fyzikálně-chemické parametry a zkoumána biodostupnost vybraných rizikových kovů. Pro zjišťování biodostupnost byla použita sekvenční extrakční analýza BCR.The diploma thesis focuses on the possibility of using mixed construction waste to improve soil properties on thermally active tailings of the Ema and Heřmanice tailings. Physico-chemical parameters were monitored, and the bioavailability of selected hazardous metals was investigated. BCR sequence extraction analysis was used to determine bioavailability.546 - Katedra environmentálního inženýrstvívýborn

Assessment of the Influence of Mine Waters on Surface Water Quality in Ostrava-Karvina Region

The study deals with the evaluation of the effects of mining water on surface water quality in the Ostrava-Karvina region.The rivers were monitored from March 2019 to February 2021and results were evaluated according to Government Regulation No. 401/2015 Coll.Mine waters are primarily loaded with dissolved substances, namely chlorides. Among others, the study focuses on parameters like temperature, pH, conductivity, sulphates, suspended solids, iron, manganese and radioactivity.The influence of mine water outlets was proven in the study, namelytheinfluence of Jeremenko Water Pit on the monitored area of Ostravice River and the influence of Karvinský Potok tributary on the monitored area of Olše River. The Orlovská stružka did not have such a demonstrable effect on the monitored area of Odra River as the aforementioned outlets on other rivers

Bioavailability of Hazardous Metals at the Ema Dump

Bakalářská práce je zaměřena na problematiku biodostupnosti vybraných rizikových kovů v lokalitě odvalu důlní hlušiny Ema, který se nachází v Ostravsko-karvinském revíru. Sledovanými rizikovými kovy byl nikl, železo, kobalt, mangan a zinek. Koncentrace jednotlivých kovů ve vzorcích půdy z dané oblasti byla stanovována sekvenční extrakční analýzou BCR.This thesis is focused on the issue of bioavailability of selected hazardous metals at the Ema dump, which is located in Ostrava-Karviná district. The monitored hazardous metals were nickel, iron, cobalt, manganese and zinc. The concentration of individual metals in soil samples from the selected area was determined by sequence extraction analysis BCR.546 - Katedra environmentálního inženýrstvívýborn

Evaluation of the Effect of De-icing Materials on Soil Quality in Selected Areas of the Moravian-Silesian Region

This study focuses on the evaluation of the influence of sodium chloride on soil quality in selected locations in the Moravian-Silesian Region. A pilot study was performed in which soil samples were collected at distances of 5 m, 10 m and 20 m perpendicular to the road. The soil samples were analyzed in laboratories to demonstrate the occurrence and possible influence of de-icing material on soil and environmental quality in the vicinity of roads
