The water-soluble Cr(VI) concentrations in cements ranged from 0.2 to 3.2 mg\/kg and represented only 1.8% of the total chromium content. The presence of chromium compounds with both chromium oxidation states of III and VI was detected in the cement samples by X-ray photoelectron spectroscopy (XPS). Leaching tests were performed in a Britton-Robinson buffer to simulate natural conditions and showed increased dissolution of Cr(VI) up to 6 mg\/kg. The highest amount of leached hexavalent chromium was detected after leaching in HCl. The findings revealed that the leaching of chromium from cements was higher by 55\u201380% than that from the cement composites. A minimum concentration was observed for all cement samples when studying the relationship between the soluble Cr(VI) and the cement storage time.<\/jats:p>","DOI":"10.3390\/ijerph15040824","type":"journal-article","created":{"date-parts":[[2018,4,24]],"date-time":"2018-04-24T04:44:48Z","timestamp":1524545088000},"page":"824","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["Study on Cr(VI) Leaching from Cement and Cement Composites"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3094-7476","authenticated-orcid":false,"given":"Adriana","family":"Estokova","sequence":"first","affiliation":[{"name":"Department of Material Engineering, Faculty of Civil Engineering, Institute of Environmental Engineering, Technical University of Kosice, Vysokoskolska 4, Kosice 04200, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lenka","family":"Palascakova","sequence":"additional","affiliation":[{"name":"Department of Material Engineering, Faculty of Civil Engineering, Institute of Environmental Engineering, Technical University of Kosice, Vysokoskolska 4, Kosice 04200, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Kanuchova","sequence":"additional","affiliation":[{"name":"Faculty of Mining, Ecology, Process Control and Geotechnology, Institute of Montaneous Sciences and Environmental Protection, Technical University of Kosice, Park Komenskeho 19, Kosice 04384, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,22]]},"reference":[{"key":"ref_1","unstructured":"Emsley, J.
