The impact of ultrasonic-assisted dyeing on ecological parameters
Alenka Ojstršek, Darinka Fakin, 2008, objavljeni znanstveni prispevek na konferenci

Opis: The main contribution of our research was to compare the impact of the conventional dyeing process and the power ultrasonic technique on dye-bath exhaustion and, consequently, on dye-bath effluents during the dyeing of four dissimilar fabrics (cotton, viscose, wool and polyamide) using chemically-different dyestuffs (reactive, direct, acid and 1:1 metal complex) at two concentrations, regarding different operational parameters, in order toestimate the environmental impact of numerous parameters and dyeing systems.The efficiency of various dyeing procedures was verified by measuring on-line absorbance, followed by the calculation of exhaustion rate. After dyeing, the selected pollution parameters were monitored in dye-baths effluents, i.e. pH, total organic carbon (TOC), chemical oxygen demand (COD), and biochemical oxygen demand (BOD5). The obtained results indicated superior exhaustion of dyestuffs during ultrasound assistance in comparison to conventional dyeing, thus causing a reduction in dyeing time and energy consumption. Moreover, the selected pollution parameters were diminished in all the dye-baths effluents after ultrasonic dyeing, thus also enhancing environmental protection.

Slovenian water management and EU - challenge and opportunity
Eugen Petrešin, Srečko Fridl, 2003, izvirni znanstveni članek

Opis: The pollution of rivers, endangered underground water and water springs, hazardous substances in the soil, uncontrolled disposal of large quantities of waste - these and many other problems severely reduce the quality of life and hinder the country's overall development. The majority of surface water courses are excessively polluted (29% fall into the third and fourth water quality class). The pollution is spreading towards river sources. The quality of groundwater has been deteriorating recently. It is evident from the "Strategy for Economic Development" of Slovenia that the approximation to the European Union is the right choice for Slovenia.

Comparison of H2O2/UV, H2O2/O3 and H2O2/Fe2+ processes for the decolorisation of vinylsulphone reactive dyes
Tanja Kurbus, Alenka Majcen Le Marechal, Darinka Brodnjak-Vončina, 2003, izvirni znanstveni članek

Opis: Six vinylsulphone reactive dyes were decolorised using three oxidation processes (H2O2/UV, H2O2/O3 and H2O2/Fe2+). The efficiency of decolorisation was measured by decolorisation time, absorbance, COD and TOC and the three methods of decolorisation are compared.

Application of elemental microanalysis to elucidate the role of spherites in the digestive gland of the helicid snail Chilostoma lefeburiana
Saška Lipovšek Delakorda, Ilse Letofsky-Papst, Tone Novak, Manuela Giovannelli, Ferdinand Hofer, Maria Anna Pabst, 2008, izvirni znanstveni članek

Opis: In this case study we present an application of different analytical electron microscopic methods in biology, to elucidate their usefulness in such investigations. Using analytical electron microscopy, spherites in the digestive gland cells of the helicid snail Chilostoma lefeburiana were examined at three stages: just before the non-feeding period of over-wintering in November, in the middle of over-wintering in February and at its end in March. A detailed characterization of changes in the elemental composition of the spherites was characterized by a combination of transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDXS), electron energy-loss spectroscopy (EELS) and energy filtering TEM (EFTEM). During over-wintering, the spherites passed the following changes. Before over-wintering in November, they consisted of striking concentric layers of electron-dense and electron-lucent zones, while in February and March they showed clear empty zones between materials of different electron density. In November spherites, C, O, Ca, P, Cl, Fe, Si, Na, K, Mg and S were detected, whereas in February ones C, O, N, Cl, Si and S were found and only C, O, N, Si and Cl were detected in March spherites. It is suggested that the elements missing in February and March were used in different physiological processes during over-wintering, like (1) the maintenance of the appropriate elemental composition of the internal environment, (2) accumulation of non-toxic waste materials that cannot be metabolized and (3) avoiding potential intoxication by contamination with toxic metals.

Opis: We describe a GIS-based real-time system for emergency response and management of air pollution accidents in an urban area. The system architecture emphasises the integration of meteorological, chemical and GIS data, dispersion modeling, decision-making and geo-spatial visualization. The threat zones, unsafe areas and safe traffic routes are obtained using an improved Gaussian plume model with a decision-making module and then exported to the Google Earth browser via “kml” file format. Several simulation scenarios were conducted and verified for notable industrial sites in Montenegro using recorded meteorological data. The results demonstrate that emergency response authorities can use the proposed methodology and system as a cost effective and accurate support tool in case of industrial or deliberate air pollution incidents.

Sensing heavy metals using mesoporous-based optical chemical sensors
Špela Korent Urek, Nina Frančič, Matejka Turel, Aleksandra Lobnik, 2013, pregledni znanstveni članek

Opis: Heavymetal pollution is one of the more serious environmental problems; therefore, there is a constant demand for the development of new analytical tools for its monitoring. An optical chemical sensor represents a good alternative to classical instrumental methods.The mesoporous materials used in optical chemical sensorsʼ fabrications have properties such as high porosity, exceptional adsorption capacity, tuneable 3D shape, geometry, and morphology, which enable improved limit of detection, response time, and selectivity properties of optical sensors. In this review, we firstly present the properties of mesoporous materials, provide a brief description of sensing mechanisms, and briefly discuss the importance of continuous monitoring. Recent advances in those mesoporous silica-based optical sensors used for heavy metal detection have been reported and their advantages and limitations also discussed. This review covers publications that have appeared since 2008.

Management of soil as a natural resource in the Savinjska statistical region in Slovenia
Milena Petauer, 2010, pregledni znanstveni članek

Opis: Animals, plants and microorganisms could not exist without soil, because without it life on Earth would not be possible. Thus we should always be concerned with preserving the soil condition. This should be a personal, a municipal, as well as a national concern. Nevertheless, the role of soil is not sufficiently incorporated into the planning of sustainable development of the Savinjska statistical region, therefore more active approaches are needed in the field of soil management and protection (education, research, raising public awareness, soil protection programs, soil related educational excursions, etc.).

Within its more than 600 pages, the monograph features interesting texts written by 31 authors from the European Union and the Russian Federation, edited by dr. Borut Jereb, Darja Kukovič and dr. Daria Meyr. The monograph “Environmental management & audit“ is composed of four books: “Scarcity and Introduction of Environmental Management”, “Management Systems”, “Controlling and Stakeholders”, and “Environmental Assessment” (Featured Articles). These four topics reflect the complexity, heterogeneity and multidisciplinary of the project Tempus RECOAUD. The reader of the monograph gets a comprehensive overview of theoretical perspectives of environmental management and audit in the chosen areas. Furthermore, the monograph also highlights the results of research in the field of environmental management and audit as well as trends and challenges in the development of this field. Providing insight into theoretical and research findings, the monograph will prove useful to both practitioners and researchers in the field of environmental management and audit; it can also be used for study purposes.
