Abstract
Volcanic hazard is ignored in natural hazard studies in Romania because no active volcano is known on its territory. However, the
2010 eruption of Eyjafjallajökull volcano in Iceland and its consequences on air traffic safety across Europe and the whole
northern hemisphere dramatically demonstrated that volcanic hazard in a certain area, such as a country, is not necessarily related
to the presence of active volcanoes in the same territory. Therefore, target-focused approa... Autori: Alexandru Szakács ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26146
INFLUENCE OF TOTAL PRECIPITATION AND AIR TEMPERATURE ON THE COMPOSITION OF MUNICIPAL LANDFILL LEACHATE

Abstract
Municipal waste landfill leachate results in different stages of waste stabilization and has a negative impact on the environment.
When implementing a new policy on waste handling, monitoring landfill leachate should be carried out under conditions of a
modern solid waste landfill. The paper discusses the quality of leachate observed in old and recently built landfills in Vilnius -
the capital city of Lithuania. The landfills are situated at a distance of 20 kilometres fro... Autori: Kristina Baziene ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26151
