Poleg vrtičkarskih območij se na vodovarstvenih območjih v Ljubljani in okolici, pojavljajo zasebni zelenjavni vrtovi. Z vidika varstva okolja je tovrstno ‘kmetijstvo v malem’ oziroma ljubiteljsko ...vrtnarstvo zanimivo zaradi nenamernega obremenjevanja okolja. Prispevek povzema rezultate diplomskega dela, v katerem smo rezultate terenskega dela povezali z dostopnimi meritvami fi tofarmacevtskih sredstev in rastlinskih hranil v tleh in pridelkih ter tako pridobili natančnejšo sliko o problematičnosti tovrstnega vrtnarstva.
Ljubljansko polje is a juncture of numerous human activities. The source of drinking water for about 300,000 residents, it holds one of the most important bodies of groundwater in the country. ...Unfortunately, the influences of urbanization, agriculture and industry that threaten and burden it are reflected in the quality and quantity of the groundwater.
The modern way of life requires the exploitation of natural resources, which leads to a significant deterioration of the environment and can even endanger human health.The basic hypothesis is that ...the population of Slovenia in general is still too inadequately informed and insufficiently environmentally educated and aware about water as a natural resource to have the motivation and capability to actively participate in the protection of water as a natural resource.Most people support environmental protection in principle, especially declaratively, since this is a socially approved action. However, when faced with restrictions that would interfere with their way of life by limiting their activities or increasing their expenses, their enthusiasm decreases rapidly. And the closer we get to actions we could define as “environmentally active,” the fewer people are actually prepared to protect the environment. Possibly a fifth of the population can be defined as people who favour environmental protection and consider it a value for which they themselves are willing to do something.The survey showed that level of education is very significant relative to people’s response to environmental problems and that the more educated are more environmentally friendly.
Using a sample of 900 persons from the urban area of Ljubljansko polje and the suburban area of iski vrsaj, we tried to determine how much local residents knew about the protection zones for drinking ...water resources. We employed a survey questionnaire and the drawing of cognitive maps. A little fewer than half of the people are aware they live in water protection zones. The proportions of those who are aware of the protection zones in Ljubljansko polje (two fifths) and in Iski vrsaj (two thirds) differ considerably. Only 280 persons, just under one third of those surveyed, drew the boundaries of the protection zones on the attached map. In Ljubljansko polje, the greatest concentration of drawn protection zones was a little north of the oldest and largest pumping station at Klece. The second largest condensation occurred in Iski vrsaj in the immediate vicinity of the Brest pumping station.
The permeation of water into groundwater in an urban environment is considerably differ-ent than that in an untransformed landscape. Built-up and open surfaces have very different proportions of ...impermeable surfaces. Due to urban land use on Ljubljansko polje, the loss of permeating precipitation water is more than 0.5m3/s or 190 mm of precipitation.
Ljubljansko polje aquifer is one of the biggest and most important aquifers in Slovenia. In general it is an unconfinedaquifer, but locally, on the SW part, layers with low hydraulic conductivity ...appear and on those areas perchedaquifers are formed. Based on lithological data from boreholes (emphasizing hydraulic conductivity of lithologicalunits) and use of geostatistical method Sequential Indicator Simulation (SIS) hydrogeological model of westernpart of Ljubljansko polje was made. In the model layers with hydraulic conductivity K < 10-6 m/s and area largerthan 0.07 km2 were defined as potential areas of perched aquifers. The majority of them are located on the foothillsof Šišenski and Grajski hrib.
The attention of numerous researches has been recently focused on the determination of pharmaceuticals and other persistent chemicals in the environment. The substances enter groundwater either ...thorough direct discharge or indirectly (through surface or waste water). Pharmaceuticals in groundwater can be regarded as artificial tracers that enable the evaluation of general anthropogenic influence on the environment and identification of the most vulnerable areas of aquifers.The article presents the properties of distribution of caffeine, carbamazepine and propyphenazone in the area of Ljubljansko polje and Ljubljansko barje. Ljubljansko polje and Barje are important drinking water resources. These pollutants are indicators of sewage system efficiency,however,in urban areas without sewage they indicate the aquifer’s ability of natural attenuation.
