20.500.12556/DiRROS-14771 The environmental impact of historical Pb-Zn mining waste deposits in Slovenia Mining waste deposits (MWDs) represent significant and constant pollution source for the environment worldwide, thus it is very important to identify and diminish their environmental impacts. The aim of this study was to determine long-term environmental impacts and their temporal variations of MWDs in Pb–Zn mining districts in Slovenia and assess stability of potentially harmful element (PHE)-bearing phases in stream water. The results showed that investigated MWDs are important source of PHEs in stream sediments and that PHEs mostly occur as fine-grained and liberated PHE-bearing ore minerals. MWDs have generally stronger impact on sediments of smaller streams draining MWDs and main streams close to their confluences, however, fine-grained PHE-bearing material is transported along major watercourses over long distances causing regional pollution. Main ore minerals are mostly soluble in stream water. However, measured PHE leaching potential of MWDs is negligible. PHE levels in stream waters are thus low, demonstrating that drainage of MWDs predominantly contributes to PHE pollution in solid particulate form. Possible long-term remediation solution that would reduce environmental impact is recovery of metals from fine grain size fractions of MWDs, which could become an effective practice in sustainable management of historical MWDs. However, further studies of MWDs’ secondary resource potential, processing technology and evaluation of environmental aspects of extraction are needed. metals stream sediment stream water characterisation mineral solubility true false true Elsevier Angleški jezik Ni določen Delo ni kategorizirano 2022-03-03 13:06:27 2022-03-03 13:46:13 2022-08-20 03:37:47 0000-00-00 00:00:00 2022 0 0 18 str. vol. 308 2022 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 504.5 0301-4797 10.1016/j.jenvman.2022.114580 99235331 1-s2.0-S0301479722001530-main.pdf 1-s2.0-S0301479722001530-main.pdf 1 B50BF885CA5529D8A4D853A885F812AD aac82235b4a548cba7a23aeb1b81b42107093514423a03a2ab8a0be76fbd5290 d36da158-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=19033 Geološki zavod Slovenije 0 0 0
