A fenntarthatĂł fejlĆdĂ©s nĂ©hĂĄny vilĂĄgmĂ©retƱ gondjĂĄrĂłl = Some global problems of sustainable development
The paper focuses on the effectiveness of the Action Plan accepted at the World Summit on Sustainable Development in Johannesburg. The Action Plan aims at the solution of some of the debated global problems. So far, no worthwhile results can be detected in the winding-up of poverty and starvation. The rich countries usually do not transfer the expected 0.7% of their national income into the relief fund and the solidarity fund is not efficient in its work either. The favourable impacts of globalisation do not prevail in the poor countries because their institutional system is underdeveloped, political insecurity predominates them and there is no sufficient qualified labour force. A modest success of the global energy policy is the coming into force of the Kyoto Protocol. The global energy structure, however, requires more significant changes in favour of the renewable energies â if the aim is to mitigate the scale of climate change
PontszerƱ szennyezĆ forrĂĄsok tĂĄjra gyakorolt hatĂĄsĂĄnak vizsgĂĄlata = Examinations on the effects on landscapes of point-sources of pollution
A talajszennyezĆ forrĂĄsokat MikepĂ©rcs Ă©s Ăjszentmargita telepĂŒlĂ©si folyĂ©konyhulladĂ©k-leĂŒrĂtĆje esetĂ©ben vizsgĂĄltuk. E szennyezĆ forrĂĄsok körĂŒl bĂ©lĂ©scsövezett furatokat lĂ©tesĂtettĂŒnk. A talaj- Ă©s vĂzmintĂĄk alapjĂĄn megĂĄllapĂtottuk, hogy bĂĄr vannak eltĂ©rĂ©sek, ĂĄltalĂĄban hasonlĂł szennyezĂ©si tendenciĂĄk tapasztalhatĂłk. MindkĂ©t helyszĂnen jelentĆs ammĂłnium- Ă©s nitrĂĄt-szennyezĂ©st mutattunk ki, a legjobb szennyezĂ©s-terjedĂ©si indikĂĄtornak pedig, a Na+ bizonyult. A szennyezĂ©s nĂ©hĂĄny szĂĄz mĂ©teres tĂĄvolsĂĄgig volt kimutathatĂł. A pontszerƱ lĂ©gszennyezĆ forrĂĄsok közĂŒl a pĂĄlhĂĄzai perlitbĂĄnya szennyezĆ hatĂĄsĂĄt vizsgĂĄltuk. MegĂĄllapĂtottuk, hogy csak a bĂĄnya nĂ©hĂĄny szĂĄz mĂ©teres körzetĂ©n belĂŒl kell jelentĆsebb porterhelĂ©ssel szĂĄmolnunk. Ebben a zĂłnĂĄban elĆfordultak az egĂ©szsĂ©gĂŒgyi hatĂĄrĂ©rtĂ©ket meghaladĂł ĂŒlepedĆ pormennyisĂ©gek, a bĂĄnyĂĄtĂłl 1 km-nĂ©l tĂĄvolabb viszont mĂĄr nem tapasztaltunk hatĂĄrĂ©rtĂ©k tĂșllĂ©pĂ©st, igaz, a szennyezĆ hatĂĄs mĂ©g 2-3 km tĂĄvolsĂĄgban is egyĂ©rtelmƱen kimutathatĂł volt. MegĂĄllapĂtĂĄst nyert, hogy a meteorolĂłgiai viszonyok jelentĆsen befolyĂĄsoljĂĄk a porszennyezĂ©s alakulĂĄsĂĄt. | We examined the soil-pollutant sources in the case of the communal sewage deposition sites in MikepĂ©rcs and Ăjszentmargita. Around these sources we established boreholes with drill-pipes. According to the water and soil samples we stated that although there are differences, in general, similar tendencies can be discovered. We detected significant ammonium and nitrate pollution in both sites, and we found out that the best indicator for the spreading of the pollution is the Na+. The pollution could be evinced in a few hundred meters from the sources. Of the point-sources of the air-pollution we examined the effects of the perlite-mine in PĂĄlhĂĄza. We found that there is more remarkable dust-load only in a few hundred meter zone around the mine. In this zone the amount of the settling dust exceeded the hygienic limit, farther than 1 km from the mine there were not higher value than the hygenic limit, but it is true that the pollutant effect could be unambiguously pointed at 2-3 km distance as well. It was proved that the weather condition notably influences the dust pollution

INTERRELATION AMONG PRECIPITATION AND ELEMENTCONTENT OF GRAPE VITIS VINIFERA L. CV. KĂKFRANKOS, GROWN IN DIFFERENT TERROIRS
Total nutrient content of soils and quantity of potentially available part
in plants are determined in this study. Main affecting factors of nutrient uptake
might be the geochemical conditions of soils and the applied agro-technological
methods, while the real uptake of plants can be influenced by precipitation and
evaporation conditions beside the rootstock and the used grafted scions. The
element content of grape berries of Vitis vinifera L. KĂ©kfrankos cultivar was
studied in identical rootstocks and scions at different production areas in
Northern Hungary, during two consecutive years with somehow contrasting
natural precipitation. Significant effect of the precipitation was found on the
elements-uptake by the plants in general. Furthermore, it was also found, that the
role of production area becomes increasingly important in grape production and
quality, as well. Higher precipitation resulting greater elemental content and
variability in comparison with the drier years
