The article presents the results of a research on the occurrence and concentration of pesticides in the groundwater of the Dravsko polje aquifer in the period from 2013 to 2015. Based on the results, ...the evaluation of spatial distribution of pesticides in groundwater and the relation to land use was performed. In different hydrogeological periods, 76 groundwater samples were collected at 19 different locations. 15 pesticides with their metabolites in groundwater were identified. Despite the prohibition of use, atrazine and its degradation product desethylatrazine still remain the most commonly detected pesticides in groundwater. They are followed by metolachlor, desethylterbutylazine and terbutylazine. The pesticides alachlor, dimetamide, metazachlor and terbutrin were not detected. The analysis of detected pesticides by land use indicates higher values in areas with intensive agricultural activity. In the northern part of the Dravsko polje, where the city of Maribor is located, pesticide concentrations are lower. Increased pesticide values occur in the southern part of the Dravsko polje, which coincides with more intensive agricultural land use of the area. The coefficient of degradation product / primary pesticide ratio (DAR and DTA/ TBA) was used to estimate the "age" of contamination from atrazine and terbutilazine. Surprising is the high incidence of atrazine, which may result from old burdens, slow decomposition and hydrogeological conditions, or the use of atrazine after the enactment of the ban
Članek temelji na skrbni analizi tako znanih kot tudi doslej neupoštevanih arhivskih virov in prinaša več izvirnih in doslej spregledanih dejstev o Veliki Marijini bratovščini na Dravskem polju, ...Marijini bratovščini v kapeli Žalostne Matere Božje v Celju in njuni združitvi. Avtorici je uspelo ugotoviti, da so bili grofje Celjski člani dravskopoljske bratovščine, da je bila prestižna kapela, ki so jo v Celju zgradili grofje Celjski, bratovščinska in da je bil proces združitve celjske in konjiške bratovščine v teku najverjetneje že v 15. stoletju. Najpomembnejšo vzpodbudo za odločitev, da tudi celjska kapela postane bratovščinska, bi lahko predstavljala kapela sv. Jurija pri avguštinskem samostanu na Dunaju, s katero so bili grofje Celjski tesno povezani.
The purpose of this article is to showcase opportunities for local communities to demonstrate self-sufficiency with respect to natural resources (gravel and sand) in the east of Slovenia. Limitations ...put in place for the exploitation of mineral resources by applicable regulations in the light of groundwater protection were analysed particularly in the context of mining undertaken in an area of shallow alluvium with a shallow groundwater table. It is essential that land disturbance (from mining activity) complies with the environmental limitations imposed by both EU and Slovenian law. The study highlights the factors directly indicating the inadequacy of the applicable regulations in Slovenia in relation to mining in areas of shallow groundwater; those limitations put in place the exploitation of mineral resources as unlawful works. This article outlines how such limitations negatively affect local communities’ self-sufficiency and the region with natural resources, specifically mineral resources. To this end, when selecting which alluvial plain to test, we focused on the area of the Drava and Ptuj Plain (Dravsko polje and Ptujsko polje) in Slovenia. The Drava River flows through the area in question across this alluvial plain. The artificially regulated power canal of the Zlatoličje hydroelectric power plant runs parallel to the river. Pursuant to environmental regulations, mineral resources can be exploited in these areas only up to two metres above the highest groundwater level. This criterion makes it almost impossible to pursue the additional exploitation of mineral resources in this area, as well as similar areas in the catchment area of the Danube River in Slovenia. We believe that in terms of the shared use of physical space it is necessary to change this limitation and link it directly to the percentage of exploited physical space and the application of relevant extraction technologies, which do not pollute groundwater either directly or indirectly. We also believe that the criterion put in place does not withstand expert judgment as the requirement for excavation to cease up to two metres above the highest groundwater level was not defined by means of the scientific method. The article analyses inconsistencies and puts forward measures for the ongoing eco-friendly and economically sustainable exploitation of mineral resources. As an alternative, we thus suggest implementing the EU Regulation via an act that would set out the necessary limitations, based on expert starting points arising from cartographic bases under consideration of the tetrahedral consensus-seeking methodology.
