Full-text available
This study examines the natural radioactivity in cements and raw materials used in cement production industry with the aim to assess the population exposure to the radiation due to their use in dwellings. The results show that the limestone is the principal contributor for the presence of ²²⁶Ra activity concentration in cements. The contribution of...
Article
The activity concentrations of terrestrial and fallout radionuclides are investigated in soil and sediments from highway stormwater retention ponds. The increased activity of ⁴⁰K, ²³⁸U and ²³²Th in sediment respect to soil samples (approximately 20% higher) is found to be correlated with the erosion of clay minerals. Therefore, it can be a useful f...
Article
This study presents the characteristics of diabase rocks and rock aggregates measured during the preliminary exploratory survey. Diabases are characterized as “high hardness”, very compact rock having low porosity and water absorption, and rock aggregates show high resistance to fragmentation (LA15) making this material suitable for construction. T...

The Naturally Occurring Radioactive Materials (NORMs) that are potentially generated from oil and gas extractions in Albania have been disposed of without regulations for many decades, and therefore, an extensive survey in one of the most productive regions (Vlora-Elbasan) was performed. A total of 52 gamma ray spectrometry measurements of soil, oi...

The feasibility of using certified reference materials for the full energy efficiency calibration of p-type coaxial high-purity germanium detectors for the determination of radioactivity in environmental samples is discussed. The main sources of uncertainty are studied and the contributions to the total uncertainty budget for the most intense gamma...

Kosovo has an area of 10908 km², with a network of 2,005 km road, and around 211300 vehicles in circulation. Most of these vehicles are older than 10 years, and do not meet the air emission technical requirements. Given the technical conditions of vehicles in use, the conditions of the road infrastructure, and the level of use of vehicles in traffi...
Conference Paper
Environmental pollution in Kosova is one of the major issues in the current phase of the development. Reports on the state of the environment warned for an "unacceptable sources of air pollution’’ whereas river and groundwater quality is affected by pollution from untreated waste water from the industry. The main “contributors” of this pollution ar...

Full-text available
To improve kinetic flotation models, many first-order flotation kinetics models with distributions of flotation rate constants were redefined so that they could all be represented by the same set of three model parameters. As a result, the width of the distribution become independent of its mean, and parameters of the model and the curve fitting er...
Article
Sulphide minerals of Pb and Zn (galenite and sphalerite), together with minerals: halcopyrite - Cu2S, pyrites and marcasyte - FeS 2, luzonite - Cu2AsS4, etc., with oxidation-reducing reactions, in contact with air and underground waters from the mines, form acid water by dissolving toxic metals in acid waters, according to the following chemical me...

Abstract: In this work we have determined the concentrations of heavy metals in soil, water and waste after flotation process around the landfill in Kishnica with SAA method at June 2010, after landfill coverage with soil. Also we have compared the concentration of heavy metals in this region, by taking samples in the same sample places were taken...
Article
Abstract: The goal of this work was to analyze the pollution influence of the deposited ash from the complex “New Ferronickel”, with heavy metals in the river Drenica and its influence in the pollution of the soil and sludge near the river. We have analyzed the heavy metals in the storage ash of the complex “New Ferronickel” which produce Ni and Fe...

Abstract: In this work we have determined the concentration of heavy metals in soil, water, sludge and waste after flotation process, in the region of Trepça at Mitrovica town in Kosova. We took samples near the Trepça complex and we have analyzed the concentrations of heavy metals with ICP-OES and AAS, in the June 2010. Soil and waste after flotat...

The Trepça Belt of Pb-Zn-Ag mineralization is located within the NNW-SSE trending Vardar zone. The Beltextends for over 80 km, and supported five mines during the period 1930-2008. It contains a number of the otherPb-Zn occurrences too. The replacement and vein type mineralization is hosted primarily by Mesozoic carbonates,but also occasionally by...

In this paper was presented the result of study of composition and distribution of lead, zinc, as two components of most economic significance in the mineral deposit Perroi i ngjyrosur (Artana) and main element of silver. The study was made in the thickness of ore bodies, within the scope of mineral ores as well as according to vertical depth of th...

The town of Mitrovica is one of the cities with the highest air pollution, in particular with heavy metals. Source of air pollution are industrial dumps generated during metallurgical mining activities, chemical, and finalization of raw materials. In this context are explored the features of air pollution case suspended particles, chemical composit...
