AB  - This study reports the contents and sources of Cu, Hg, Cr, Ni, Co, Zn, Pb, Cd, As, and B pollution in soil samples from Srem in the province of Vojvodina (Republic of Serbia). They are collected in the vicinity of local industrial facilities. The main objective of this study is evaluating the impact of the industrial facilities on the eventual contamination of soils used mostly for agricultural manufacturing. This paper describes the implementation of the combination of methods to estimate the ecological status and determine potential ecological risk. This study applies sequential extraction, pollution indices, comparison with the guidelines, and statistical analysis. Other soil parameters, such as organic matter content, pH, and clay content were measured to evaluate their influence on the trace element content. The investigated soil samples exhibited the raised contents of Ni, Hg, and Cu. Elevated contents of toxic elements observed in localities accommodated within an impact zone affected by industrial complexes, indicating a correlation between the contamination of surrounding soil and potential impact on plants. The most mobile elements are Hg, Cd, and B, while Cr is the least mobile and potential least bioavailable. The results indicate Cr and Ni content increase marking the presence of bedrock, notably in the area of underlying ultramafic rocks and the surface zones influenced by diluvial-proluvial and alluvial processes. The second source of Cr and Ni in the soils of Srem is industrial activities such as leather, cement industry, as well as the metal processing factory.

AB  - Five typical bauxite samples from three ore deposits from the wider area of Grebnik Mt. (Metohija, Serbia) were examined with the optical microscopic, X-ray powder diffraction (XRPD) and chemical methods. The occurrences in bauxites were studied and described and the presence of major minerals was determined: diaspore, boehmite and hematite; minor minerals: quartz, goethite, rutile, kaolinite and hydro-hematite; as well as anatase, brookite, magnetite and chromite, which occur only sporadically. According to the quantity of main Al-bearers, three types of bauxite ore were recognized: diaspore, boehmite and boehmite-diaspore. Unit cell dimensions of major minerals were determined, mostly with values within reference data. However, all of the studied hematites have smaller a0 and V0 values, most probably due to the substitution of Fe3+ by Al3+. All samples are further classified as iron-rich and ferritic bauxites. It was found that there were changes in origin conditions between major Al-hydroxides minerals and hematite, as well as between the diaspore and boehmite. Determined chemical compositions put this raw material into high-quality raw materials for obtaining the electro corundum and alumina. The synthesis of the obtained data indicate that Grebnik’s bauxites have some unique characteristics, more or less different from most of the World’s known bauxite ore deposits.
AB  - Пет типичних узорака боксита из три рудна лежишта са ширег подручја планине Гребник (Метохија, Србија) су проучавани оптичко микроскопским, рендгенском дифракцијом праха (XRPD) и хемијским методама. Проучаване су и описане појаве у бокситима и утврђено је присуство главних минерала: дијаспора, бемита и хематита; минорних минерала: кварца, гетита, рутила, каолинита и хидрохематита; као и анатаса, брукита, магнетита и хромита, који се јављају само спорадично. Према количини главних носилаца алуминијума, утврђена су три типа руде боксита: дијаспорски, бемитски и бемитско-дијаспорски. Израчунате су
димензије јединичних ћелија главних минерала, углавном са вредностима које су у оквиру литературних података. Међутим, сви проучавани хематити имају мање вредности a0 и V0
, највероватније услед замењивања Fe3+ са Al3+. Сви узорци су даље класификовани као гвожђем-богати и феритични боксити. Утврђено је да су се догодиле промене у условима постанка између главних минерала Al-хидроксида и хематита, као и између дија -
спора и бемита. Одређени хемијски састави стављају ову сировину у високо-квалитетне сировине за добијање електро корунда и глинице. Синтеза добијених података указује на то да Гребнички боксити имају неке јединствене карактеристике, које се мање или више разликују од већине светски познатих лежишта руде боксита.

AB  - Powder diffraction patterns were indiced and there were determined qualitative, semiquantitative compositions of the mineral raw material, “baked” mineral raw material and brick. There were established changes of the mineral compositions, mineral transformations and precrystallizations at different temperatures. There were calculated and compared unit cell dimensions of the kyanite, corundum, rutile, andalusite, sillimanite and mullite. At corundum and rutile they are mostly unchangeable and in the range of the standard error. Sillimanite and mullite have in the brick samples ao-axis bigger and bo-axis smaller than in the “baked” mineral raw material samples, while co-axis and volume-Vo remained almost constant. That indicate to the partially thermal expansion in the ao-axis direction against bo-axis and to the increase of the Al2O3 content in the mullite's structure from the brick at respect to the mullite from the “baked” mineral raw material. 
Regard to the literature datas, smaller unit cell dimensions has kyanite, corundum and mullite, bigger andalusite and sillimanite, while rutile has approximatively equal. The most quantity mineral in the samples of the “baked” mineral raw material and brick is mullite, which indicate to their excellent characteristics and usage. At basis of the mineral composition in the “baked” mineral raw material and brick samples it was estimated Al2O3 content of about 60%.
