Hypersaline environments pose a number of ecological and metabolic challenges to the organisms that live in them. Primary producers, such as halotolerant species of the green microalgal genus Dunaliella, are no exception. In this paper we focus on the problems posed to the acquisition and metabolism...

Radiocaesium is an isotope that can enter the food chain after having been absorbed by plants from soil. Our ability to predict the consequences of an accidental release of 137Cs depends mainly on the level of understanding of the mechanisms involved in 137Cs interactions with different components...

The understanding of marine eutrophication in semi enclosed areas due to agricultural runoff, assumes a more integrated approach taking into account the agricultural watershed, seasonal patterns of soil nutrients, rates of erosion and vegetation types. In the present case study in the Gulf of Geras...

Undoubtedly, sun is the cleanest energy source. Specific systems are needed however for the collection and transformation of solar energy and the manufacturing processes of such systems, as well as the production of the raw materials required, are associated with impacts to the environment. As a...

In this paper an Environmental Impact Assessment Multicriteria Decision Analysis System for irrigation projects (EIAMDAS) used as a comprehensive tool that enables comparison between irrigation project alternatives is presented. The comparison is based upon all relevant aspects of the surrounding...

The ENVIRON model estimates environmental impacts (positive, negative) from the introduction and use of Advanced Communications (AC); Information Society Technologies (IST) in industrial, commercial and business sectors in Greece. The model estimates effects on output, employment, income...

Life cycle assessment (LCA) is a technique for holistic environmental assessments of products and processes. The unique feature of this methodology is its focus on the entire life cycle of a product, from raw material extraction to final disposition. In order to assess the role of LCA in...

The use of organic manures as amendments to improve soil organic matter level and long term soil fertility and productivity is gaining importance. The disposal of the great quantity of organic wastes produced by the municipal, agricultural and agroindustrial activities, is causing energetic...

3,4-dichloroaniline (3,4-DCA) is a hardly biodegradable and hydrolysable compound, characterized as a persistent pollutant for water, soil and sediment and highly toxic for living organisms. In this work, the impact of different micrometeorological conditions on uptake of 3,4-DCA was investigated in...

This study concerns a protected area in northern Greece and examines how local people’s occupation influences their perception of environmental impacts and their views and information about the area. The target groups were local residents that (a) were employed in the primary sector, (b) were...

Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO2, NO, and NO2 from “sweet” natural gas while “sour” gas emits SO2 in addition; incomplete combustion...

One of the main environmental impacts of pig farms are the swine odours emitted from the various stages of the process. The main cause of odour emissions from pig farms are the anaerobic processes in manure. Numerous factors affect odour emissions such as diet, manure management and manure age. The...

In this paper, three-dimensional numerical simulations are used to simulate the wind flow structure over coal stockpiles of a real configuration of a power plant. Two configurations are tested for various wind directions: the first one without representing the buildings and the second one with the...

Numerous methods have been developed for the quantitative assessment of eutrophication: statistical techniques, simulation models and water quality indicators are the most widely used techniques to assess trophic levels. All these methods share a common goal: to evaluate the environmental impact due...

The multiple objectives optimization in water resources planning consists in trading multiple and conflicting objectives, forming a complex and dynamic process. In the last four decades multiobjective decisions based on fuzzy sets have been evolved and considerable research spawned into the...

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 (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...

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...

The EU Directives and legislation by worldwide environmental authorities impose constantly lower levels for the airborne pollutant emissions of internal combustion engines towards the goal of zero emission vehicles. During the last decade, engine manufacturers, refiners and fuel companies invest...

Urban air quality nowadays is one of the major environmental issues, due to its impact to various health problems, caused by the daily exposure of the population in dangerous air pollutants. The highest levels of air pollutants are usually observed in street canyons, emitted by urban traffic. To...

The assessment of the applicability and suitability of potential measures and instruments is crucial in the strategic planning of water resources management. This paper presents a methodology founded on scenario analysis for assessing potentially applicable water management options in a regional...

This paper presents a step-by-step methodological approach for the development and evaluation of strategies for water deficient regions. The primary focus of the approach followed was the mitigation of water stress, while applying the principles of Integrated Water Resources Management and the EU...

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the...
