The physico-mechanical, chemical and mineralogical characteristics of volcanic glass (perlite) from the Mariovo region (Macedonia) as well changes that occur during its thermal treatment were investigated to demonstrate utilization for industrial use.The native perlite was characterized by analysis, X-ray powder diffraction (XRPD), infrared (IR) spectroscopy, analysis (TGA/DTA), scanning electron microscopy (SEM-EDX), transmission (TEM), solid-state NMR.The examination suggests represents an...
Although North Macedonia covers only 0.7 % of the Earth's surface, it contains 3 world's mineral deposits (Jovanovski et al. 2018). Both historical and recent mining operations in country have left extensive waste deposits, particularly from focused on exploration antimony (Sb), arsenic (As), chromium (Cr), copper (Cu), lead (Pb), zinc (Zn) thallium (Tl). Over past six years, we intensively studied mineralogy geochemistry two abandoned Lojane, a former Sb-As-Cr mine, Allchar, Tl-As-Sb-Au...
The Demir Kapija ophiolitic complex in southern Macedonia–FYROM (Former Yugoslav Republic of Macedonia) represents the southernmost exposure Tethyan Eastern Vardar unit Mediterranean. It consists a mafic volcanic sequence (pillow basalts, sheeted dyke diabases and gabbros) that was subsequently intruded by island arc magmas with without adakitic affinity. is characterized slightly increased ratios large ion lithophile elements to high field strength (LILE/HFSE), flat rare earth element (REE)...
In the Lojane area (North Macedonia) ores of Sb (stibnite), As (realgar), and Cr (chromite) were mined processed in a metallurgical plant until 1979.Over one million tons flotation tailings containing As, Sb, other hazardous substances are located an open dump site for waste created by mine.The is completely unprotected, its orange color reflects very high concentration arsenic (fine-grained realgar superficially altered to pararealgar).In order better understand weathering behavior these...
Secondary minerals could be effective scavengers of toxic arsenic (As) and thallium (Tl). In environments polluted by mining, these elements are abundant both in acid rock/mine drainage scenarios, as well carbonate-buffered environments. this study we have investigated the behavior As Tl during weathering mine waste dumps an associated technosol sample from Crven Dol locality (Allchar Tl–As–Sb–Au deposit, North Macedonia) contaminated with up to 142 g kg−1 18 Tl, making it As- Tl-extreme...
As part of a survey on concentrations radon, thoron and their decay products in different indoor environments the Balkan region involving international collaboration, measurements were performed 43 schools from 5 municipalities Republic Macedonia. The time-integrated radon gas (CRn CTn) measured by CR-39 (placed chambers with diffusion barriers), whereas equilibrium equivalent (EERC EETC) using direct radon-thoron progeny sensors consisting LR-115 nuclear track detectors. detectors deployed...
The authors present the results of a year-long survey indoor radon concentration levels in FYR Macedonia. A total number 437 dwellings eight statistical regions were subject to measurements by using CR-39 track detectors. annual mean each measuring site was estimated from four individual with 3 months duration. period December 2008 2009. distribution nearly log-normal. arithmetic and geometric values value be 105 ± 84 84*/1.9 Bq m(-3), respectively. effective dose due exposure 2.1*/1.9 mSv y(-1).
Abstract The waning stage(s) of the Tethyan ocean(s) in Balkans are not well understood. Controversy centres on origin and life‐span Cretaceous Sava Zone, which is allegedly a remnant last oceanic domain Balkan Peninsula, defining youngest suture between Eurasia‐ Adria‐derived plates. In order to investigate what extent Late‐Cretaceous volcanism within Zone consistent with this model we present new age data together trace‐element Sr–Nd–Pb isotope for Klepa basaltic lavas from central...
The laterite Ni-smelting operations at Vozarci, Republic North Macedonia have produced large amounts of smelting wastes dumped in the close vicinity smelter. We examined phase composition and chemistry various types slags (electric furnace slags, converter slag, magnetic slag) with special focus on phases containing potentially toxic elements terms their mineralogy, chemical composition, responses to weathering. Electric contain between 35 47 wt.% SiO2, 21–40 Fe2O3, 13–23 MgO; are Fe-rich...
ABSTRACT The Allchar mineral mine is one of the oldest arsenic–antimony mines in Republic North Macedonia. a well-known reservoir worldwide purest source thallium-bearing mineral, lorandite (TlAsS2). current study evaluated bacterial and fungal diversity three As- Tl-contaminated sites mine. We used combination high-throughput sequencing bioinformatic analyses. Trace metal content was detected using inductively coupled plasma optical emission spectrometry. Our analysis showed presence 25...
To improve the ability of rice husk to purify colored wastewater, effluent from alkaline scouring cotton yarn was used immediately after (without cooling and additionally added chemicals) in order remove non-cellulosic silicon-lignin shield husk’s surface.

The skin is exposed to numerous particulate and gaseous air pollutants. ones that need particular attention are the particles adhere surface, which can later cause direct damage. This study aimed characterize pollution (AP) adhered human by using scanning electron microscopy (SEM) combined with X-ray dispersive energy spectrometry (EDX).Tape stripping was performed from six healthy volunteers urban AP collect stratum corneum samples cheeks forehead. were analysed SEM equipped EDX system a...
The use of FflR spectroscopy to distinguish between some geologically im portant carbonate minerals (calcite -CitCD), aragonite -CaCD), siderite -FeCD.I , magnesite -MgCD) and dolomite -CaMg(CD.1h) originating from Macedonia detect mineral impurities in them is considered.11 was shown that the series studied isomorphous c~lcite type an ideal test case for evaluating fluence corresponding cation upon band frequencies or v), V2 v~ modes their ini'rared spectra, It enables calcite carbonates...
The Rzanovo deposit lies within the western ophiolite belt of Vardar zone. Its main geological units are discussed in terms their mineralogy, petrology and petrological evolution. Minerals observed include: magnetite, hematite, clinochlore, talc, sepiolite, magnesioriebeckite, lizardite, dolomite, phlogopite, stilpnomelane, quartz, albite, pyrite, maghemite, pyrrhotine, digenite millerite. Some minerals had non-distinct morphologies ambiguous characteristics, preventing identification on...
We present a method for the estimation of annual radon concentration based on short-term (three months) measurements. The study involves results from two independent sets indoor measurements performed in 16 cities Republic Macedonia. first data set contains winter and obtained during National survey 2010 second, only measured 2013. Both pertain to same have been applying methodology ground floor dwellings. appeared be consistent dispersion was low. Linear regression analysis revealed high...
<p> The kinetics of manganese adsorption onto natural zeolite (clinoptilolite) were studied with respect to initial metal ion concentration and adsorbent mass. In order select the main rate-determining step in overall uptake mechanism, a series experiments performed under batch conditions from single solutions. Data obtained kinetic are interpreted terms Pseudo-second model, Weber Morris model proposed by Furusawa Smith.</p><p> is reasonably fast. It means that first 20 min...
Abstract The paper deals with the recent survey of indoor radon (Rn) results in schools, where paired CR-39 detectors were simultaneously exposed to different long-term periods, i.e., one detector was during whole year and other period school duration. To be able compare obtained, for its analysis, relative bias U tests used. It found that there are no systematic differences between results, which points exposure summer vacations did not affect estimated average annual concentration....
