The negative effect of higher temperatures on the solubility of calcium sulfate (13.08 mmol/dm3 at95°C vs. 15.43 mmol/dm3 at 40°C) was utilized. In several repeated cycles, calcium sulfate component was progressively dissolvedin water at room temperature and then precipitated at 100°C, using the same liquid phase throughout the experiment. Therefore,phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant, and the mass balance forthe experiment was calculated. Elemental, XRD and SEM-EDS analyses were performed on raw phosphogypsum, purified gypsumand insoluble residue. The whiteness of raw phosphogypsum and purified gypsum were determined and compared. The main objectiveof the study was to investigate the nature of insoluble impurities, in order to define and optimize the methods for their removalduring a potential industrial processing of phosphogypsum.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44295894","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}

The samples of forest soils from the Moravian-Silesian Beskydy Mountains (the Czech Republic) were used foridentification of emissions sources of particles with magnetic ordering. Magnetic susceptibility was measured at bulk samples ofgrain size class under 2 mm. Microanalysis using electron microscope with an energy dispersive X-ray spectrometer was used forthe determination of particles in the magnetic fraction. The samples of dust from the sintering plant of the Iron Works in the townof Třinec were analysed. The values of magnetic susceptibility of forest soils in the Třinec region are increased. In the relatively nearvicinity of the industrial area, the average value for Javorový Mount was 7.90×10-6 m3/kg, for Ostrý Mount it was 6.69×10-6 m3/kg. It was proved that they were higher than the average values from the Beskydy Mountains (4.64×10-6 m3/kg). The concentrationsof lead and magnetic susceptibility in soils showed significant correlation dependence (rs = 0.85). The iron and steel industryrepresent the primary source of the pollution load in forest soils of the studied area. Statistically, significant dependences betweenthe organic matter content and the lead and zinc concentrations as well as between the magnetic susceptibility values and the ironconcentrations in forest soils were found. It was confirmed that the airborne particles are deposited on vegetation and accumulatedin the organic horizon of forest soils.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46668324","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}

Th e aim of the study was to characterize the composition of bacterial population in environment with high concentration of iron and sulfur compounds represented by neutral mine drainage water of Elizabeth’s shaft , Slovinky (Slovakia). Th e pH value of drainage water decreased from 7.1 to 6.5 during the years 2008–2014. Direct microscopic observations, cultivation methods, and 454 pyrosequencing of the 16S rRNA gene amplicons were used to examine the bacterial population. Microscopic observations identifi ed iron–oxidizing Proteobacteria of the genera Gallionella and Leptothrix which occurrence was not changed during the years 2008–2014. Using 454 pyrosequencing, there were identifi ed members of 204 bacterial genera that belonged to 25 phyla. Proteobacteria (69.55%), followed by Chlorofl exi (10.31%) and Actinobacteria (4.24%) dominated the bacterial community. Genera Azotobacter (24.52%) and Pseudomonas (14.15%), followed by iron–oxidizing Proteobacteria Dechloromonas (11%) and Methyloversatilis (8.53%) were most abundant within bacterial community. Typical sulfur bacteria were detected with lower frequency, e.g., Desulfobacteraceae (0.25%), Desulfovibrionaceae (0.16%), or Desulfobulbaceae (0.11%). Our data indicate that the composition of bacterial community of the Elizabeth’s shaft drainage water refl ects observed neutral pH, high level of iron and sulfur ions in this aquatic habitat.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43006282","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}

These problems are primarily related to the release of bacterially produced hydrogen sulphide from wastewater to the atmosphere during sewage transports that dissolves in the condensate on the sewer crown. In the event sulphur-oxidizing bacteria oxidize the dissolved hydrogen sulphide and other sulphur compounds to sulphuric acid, which corrodes the concrete. The concrete gradually expands causing cracks and ruptures, loss of strength and overall decay of concrete. The paper is focused on the investigation of the concrete specimens surface biodegradation study. From the viewpoint of concrete materials biodeterioration, mainly the bacteria sulphurand sulphide-oxidising bacteria and sulphate-reducing bacteria are important and interesting. The role of bacteria mentioned above has been linked to the generation of the biogenic sulphuric acid resulting in corrosion process by dissolution of calcium containing minerals from the concrete matrices. The penetration of the corrosion was manifested by structural changes of concrete samples. The surface structure changes were by stereomicroscopy and atomic force microscopy (AFM) investigated.","PeriodicalId":79497,"journal":{"name":"Immunotechnology : an international journal of immunological engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42027575","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}
