摘要

研究区域选择在奥尔库什地区原洗选厂废弃物、浮选废弃物排土场和露天矿非硫化物锌铅矿污染严重的地区。采用XRD、SEM/EDS等方法对植物根表面和根际的亚显微相进行了研究。研究了亚显微金属化相的形态及其赋存方式。通过能谱分析，确定了其结构中Zn、Pb、Fe、Mn、Cd等物相和矿物团聚体。洗选厂和露天开采地区的土壤受到各种矿物复合物的污染。不稳定的铁、铅、钙硫酸盐的出现表明这些废物仍具有强烈的地球化学活性。

Forms of heavy metals (Zn, Pb, Cd) occuring in rhizospheres from the areas of former and contemporary Zn-Pb ore mining

: The research areas were selected in the regions heavily polluted by wastes from the former washing plant, flotation waste dump and by non-sulphide Zn-Pb ores from open pit mining in the Olkusz region. The submicroscopic phases occurring in the surface of plant roots and in the rhizospheres were investigated by XRD and SEM/EDS methods. Morphology of submicroscopic metalliferous phases and their manner of occurrence were the subject of study. The analysis of EDS spectra enabled to identify phases and mineral aggregates including Zn, Pb, Fe, Mn, Cd in their structure. The soils from the washing plant and areas of open pit exploitation are contaminated by diverse complexes of minerals. The occurrence of unstable Fe, Pb, Ca sulphates indicate that these wastes are still intensively geochemically active.

期刊介绍： Mining Scince. Scientific Papers of the Department Geoengineering, Mining and Geology of the Wroclaw University of Technology. The journal publishes original papers on mining and geology, geo-engineering and the related issues. The journal is devoted to the following topics: fundamental research in mining, underground and open-cast mining technologies, blasting technology, design and construction of mines, geomechanics and geotechnical engineering, mine ventilation, fluid mechanics and its application in mining, mining machinery and condition monitoring, mineral processing, environmental protection and waste utilization. The journal also accepts papers concerns geoengineering which is a sciences covering mining construction, geotechnical engineering, GIS, and earth sciences.
