Slag and ash chemistry after high-calcium lignite combustion in a pulverized coal-fired power plant
General
More than 73% of the electrical power requirements of Greece are generated in lignite-fired power plants. Greece is the thirteenth largest coal and the fifth largest lignite producer in the world. The lack of domestic high-rank coals makes necessary to use low quality lignite for power generation in...
Leaching of lead from clinoptilolite at acidic conditions
General
The leachability of Pb2+ from natural greek clinoptilolite was investigated according to the standard procedures TCLP/EPA/RCRA (1311), EPA Methods 1310, 1320 and DIN 38414-S4. Through SEM/EDAX analysis it was shown that lead was uniformly loaded onto the particles subjected to acid treatment...
Marine monitoring along the eastern coastal area of the Island of Lesvos, Greece during 2004 in the Framework of MEDPOL III
General
The present survey was carried out in the framework of MEDPOL Phase III (2004 – 2006), aiming to provide recent information for the long-term monitoring of pollution trends in selected susceptible marine environments along the Mediterranean coastline. Information was collected from a network of four...
Leaching and transport of Zn through soil profiles in a seasonal river of a mining area in SE Spain
General
Metal pollution can have adverse effects on human health but also on environment. Usually, risk is assessed on the basis of the total concentration of a trace metal in soils and sediments. Nevertheless, for checking the short and long-term true environmental impact of a trace element, one of the...
Environmental Impact Assessment and Integrated Water Resources Management
General
Environmental Impact Assessment (EIA) plays an important role in the framework of the efforts aiming at the formulation of a complete water resources management. In our paper this issue is examined in an integrated way. The following issues are particularly examined : the notion of the EIA in...
Assessment of mining soil improvement after construction and demolition wastes amendment additions evaluated by microbiological analysis
General
Major environmental problems in metallic mining areas come from the hazard of metal pollution of surrounding areas. Therefore, an appropriated management of these soils is necessary for minimizing the associated risks. Some properties of mining soils, such as elevated metal concentrations, pH and...
Is the Last Years Abrupt Warming in the National Observatory of Athens Records a Climate Change Manifestation?
General
Instrumental data time series show an average global warming of approximately 0.90C over the last century. Eastern Mediterranean air temperature follows the northern hemisphere (NH) secular trend till 1970s, while the NH warming of the last 30 years is not noticeable in the eastern Mediterranean...
Adsorption of hexavalent uranium on dunite
General
Pollution of the environment with uranium and associated health effects to human have recently become of major concern, particularly due to the use of depleted uranium in armourbreaking bullets. Indeed, uranium in environmentally significant concentrations is found near to uranium mining and...
A Wind-Driven Hydrodynamic and Pollutant Transport Model
General
A program is developed that includes two hydrodynamic models, a 2D depth-averaged (2DH) and a Quasi-3D (Q3D), and a pollutant transport model that uses a 1st order upwinding and a 3rd order QUICKEST numerical schemes. Several tests were performed in two test basins in order to examine the...
Mercury content in garden soils of urban agglomeration
General
The study report the degree of mercury contamination in garden soils of urban agglomeration and local sources of heavy metals emission like traffic and coal combustion. The urban soils have been compared with cultivated rural counterparts, developed on similar parent material. Mercury contents in...
