Risk assessment of oil spill accidents
Hazardous Substances and Risk Analysis
The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts. This was achieved via the effective cooperation between the National Technical University of Athens (NTUA) and the Bogazici University (BU) within...
Integrated management of karstic waters – A case study of the Zlatibor mountain massif, Serbia
Water Resources Management
The Zlatibor mountain massif has significantly changed for the past 20 years due to the development of tourism, which has resulted in an increase in water consumption and environmental threats. This area abounds in considerable surface and groundwater resources, which are not utilised adequately...
Environmental impact assessment of a METRO infrastructure facility construction by modelling water and soil pollution
Environmental Management and Policies
The construction of large infrastructure projects such as highways, railroads, landfills, airports, harbours offers great social-economic opportunities for the development of a region; it is also mainly responsible for the deterioration of natural environment in the greater areas where these...
Using a market-type allocation system to confront water scarcity: an inter-district approach in Greece
Water Resources Management
This study examines the implication of a market-based system to allocate water regionally in one of the most intensively irrigated areas of Greece. The proposed approach combines elements from administrative allocation and tradable water rights in order to assess several water supply scenarios under...
Adsorption kinetics of Direct Black 38 on nitrogen-doped TiO2
Water and Wastewater Treatment
In this work, three samples of nitrogen-doped TiO 2 prepared at different calcination temperatures (400, 450 and 500 °C) were applied for the adsorption of Direct Black 38. Kinetic studies about the adsorption of Direct Black 38 on nitrogen-doped TiO 2 were performed under different initial dye...
Effect of soil scarification on natural regeneration of mature scots pine (Pinus sylvestris) stands in Greece
Ecosystems and Natural Resources Management
The natural regeneration of Scots pine stands at the Sarakatsana location in the Pieria Mountains improved considerably after the removal of the dense ground vegetation followed mechanical soil scarification. The experimental design consisted of replications on scarified and non-scarified soil. The...
Iron and steel slag: An alternative source of raw materials for porcelain ceramics
Solid Waste Management
Iron and steel industry generates substantial amount of inorganic solid wastes namely blast furnace (BF), Linz-Donawitz (LD) slag from the metallurgical process and fly ash from thermal power plant which creates environmental pollution when dumped in open land. In this investigation, BF and LD slag...
Preliminary study of the effect of using biosorbents on the pollution of the treated water
Water and Wastewater Treatment
Several adsorbents have been tried out by researchers to remove different pollutants from wastewater. However, the adverse effect of these biosorbents on the treated water and the possibility of leaching new pollutants to the treated water have not been investigated. A batch technique was employed...
