Impact of nuclear energy objects on lake environment: Lake Druksiai case

The impact of a nuclear power plant on the environment consists basically of the thermal load,radioactive and chemical waste produced during its operation. Lake Druksiai – the cooling basin of the only Nuclear Power Plant in Lithuania (INPP) has been exposed to severe anthropogenic pressures since 1984 when the first unit (out of two) was put into operation.

It was a combination of thermal releases and chemical contamination which leads to local disturbances of ecological equilibrium, changes of trophic status, and changes in the species structure of lake ecosystem. Traces of radionuclides originating from the INPP were found in the surface water of Druksiai Lake as well. Until now, the non-radioactive factors of impact to the lake ecosystem were more evident than radioactive contamination within 25 years of operation of NPP.

Überschnittene Großlochbohrung als Bodenaustauschverfahren bei der Sanierung ökologischer Altlasten
© wvgw Wirtschafts- und Verlagsgesellschaft Gas und Wasser mbH (3/2016)
Der Austausch kontaminierten Bodens in der grundwassergesättigten Zone stellt hohe Ansprüche an den Tiefbau sowie den Arbeits- und Immissionsschutz. In den letzten Jahren werden zunehmend überschnittene Großlochbohrungen als Sanierungsverfahren angewendet, da diese kleinräumigen Verfahren bis in größere Tiefen anwendbar sind, ohne umfangreiche Verbauarbeiten oder Grundwasserabsenkungen vornehmen zu müssen. Anhand einer erfolgreichen Anwendung dieser Sanierungsmethode auf dem Grundstück einer ehemaligen chemischen Reinigung in Berlin werden Planung und Ausführung dieser Methode erläutert.

The FOOTPRINT software tools: Pesticide risk assessment and management in the EU at different spatial scales
© Aristotle University of Thessaloniki (6/2009)
In the EU-project FOOTPRINT three pesticide risk assessment and management tools were developed, for use at different spatial scales. The three FOOTPRINT tools share the same underlying science, based on the consistent identification of environmental characteristics driving the fate of agriculturally applied pesticides and their interpretation to parameterise state of the art modelling applications thus providing an integrated solution to pesticide risk assessment and management in the EU.

Analysis of the regional-scale influence of agricultural ecosystem parameters on zinc concentrations of soil and rice grains using regression methods
© Aristotle University of Thessaloniki (6/2009)
We investigated the influence of various metrical and categorical parameters characterizing soil, climate, parent material, physiography and agricultural management on soil and rice grain Zn concentrations in two provinces of Central Iran. Total soil Zn was found to be a function of parent material, physiographic unit, crop rotation system, total soil P concentration and soil clay content. Except for soil CaCO3 and OC the parameters considered in our analysis, however, had no strong effect on grain Zn concentrations. The analysis showed that generally available information such as basic soil properties, parent material and crop rotation system can be very helpful in predicting the Zn status of agricultural soils on a regional scale, while it helped much less in predicting grain Zn concentrations in rice.

Lead fractionation in soil as affected by organic and inorganic amendments
© Aristotle University of Thessaloniki (6/2009)
The Pb fractionation in the sewage sludge and cow manure before and after removal of organic carbon, reducible Fe, iron oxide and Pb(NO3)2 salt was determined by a sequential extraction method. Despite cow manure and sewage sludge had high level of organic carbon (54 and 31%, respectively), most of the Pb in these amendments was found in the inorganic (oxide) fraction.

Soil carbon sequestration affected by cultivation of poor pastures in arid regions of Central Iran
© Aristotle University of Thessaloniki (6/2009)
Soil carbon sequestration through changes in land use and management is one of the important strategies to mitigate the global greenhouse effect. This study was conducted to estimate the rate of soils carbon sequestration in land use changes from poor pastures (PP) to wheat fields (WF) and poor pastures to alfalfa fields (AF) occurring in Abarkooh plain, Central Iran.
