In this study, ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) stereo imagery was analysed in combination with Global Positioning System (GPS) data and field observations, using Geographical Information Systems (GIS) techniques to examine the potential of satellite remote...

The results of a research study about the groundwater quality in western Thessaly, that took place during the period 2001-2002, are presented in this paper. The study included two samplings during May and August of 2002. In May the water table is at high level while at the end of the summer the...

A pilot-plant study was carried out with the water supply to Athens water works filtered through a granular activated carbon (GAC) filter- adsorber. The objective of this study was to evaluate the performance of GAC for the removal from drinking water of the two main groups of disinfection by...

Results of a monitoring project for the water quality of three important rivers of western Greece (Acheloos, Louros and Acherontas) are presented in this paper. The results include the concentrations as well as the temporal and spatial distributions of nitrates, nitrites, phosphates, ammonia and...

The levels and the distribution of metals, hydrocarbons and organochlorine compounds were studied in mussels (Mytilus galloprovincialis) and surface sediments collected from Thermaikos gulf in March 1999. Hydrocarbon values were indicative of moderate pollution, whereas in some cases clear evidence...

A Web-node has been created in order to address the specific needs of the small and medium enterprises (SMEs) of three important economic areas in the Mediterranean region, the food, textile and hotel sectors. The node provides important information on the market structure in the relevant sectors...

In this paper a review of most recent practices in the field of Risk analysis are presented. Then the available data for oil spill incidents in the area of Crete covering the period 1995-1999 are analysed and discussed in detail. Risk analysis tables are produced in order to formulate the spatial...

Over the last decades intensified agricultural production is applied in the northern coastal part of Korinthos Prefecture (Peloponnese, Greece). An aquifer system occurs in the recent basin deposits, which consists of unconsolidated material, namely sands, pebbles and fine clay to silty sand...

The present paper examines a small and deep (53 m) salty lake, as well as the adjacent harbor of Aghios Nikolaos (Crete). The survey was carried out in 1996. Physicochemical parameters indicated that the main characteristics of the system are the inflow of karstic water from underwater springs...

Recently, environmental issues have become a priority in the agenda of ASEAN countries due to the serious impacts of environmental degradation. Similar to other countries, ASEAN countries have their own strengths and weaknesses in environmental protection, which depend on their policies and law...

A risk-based decision analysis methodology is presented, that can be used as a water policy tool in the design of economic incentive instruments, under conditions of uncertainty. A contaminated groundwater resource system with unknown hydrogeological parameters is used as a case study. The polluter...

A model and spreadsheet-based numeric approximation for computing risk-based soil cleanup level to be protective of petroleum-contaminated soil to an indoor air exposure pathway is presented. The algorithm incorporates traditional equilibrium partitioning equations (3 or 4-phase) for the...

Accumulation of airborne pollutants in vegetation is an important initial step in the uptake process of the terrestrial food web, providing direct and indirect routes by which biota and, eventually, humans are exposed to chemicals. A set of algorithms for estimating atmospheric pollutant...

In the Mediterranean region, fire is a natural factor, which contributes in the shaping of landscape and the preservation of a high degree of biodiversity. However, often repeated burning has negative impacts on the forested landscapes. When the processes of natural or artificial regeneration are...

The sustainable management of water resources often requires the identification of wastewater as a valued source of water. Although the benefits of wastewater reuse and reclamation have increased significantly in Europe because of the advances in effectiveness of wastewater treatment and...

In the present work, Fourier Analysis is applied to the mean monthly NOx concentrations of the period 1989-1999, for a network of 7 stations. Treating NO and NO2 as a single primary pollutant, we succeeded the assessment of NOx concentrations. The main causes of NOx emissions in urban areas are the...

It is well known that the toxicokinetics (i.e. absorption, distribution, metabolism and excretion) of mercury is highly dependent on the form of mercury to which a receptor has been exposed. The aim of this paper is to summarize the available health effects information for mercury and mercury...

The paper presents some interesting results of metal speciation studies employing Anodic Stripping Voltammetry (ASV) applied in a dynamic natural system such as the brakish – marine interface formed between the polluted waters discharged by the Koumoundouros lake and the marine ones of the Gulf of...

Soil-contamination from toxic explosive residues at military bases throughout the world, is a major environmental concern. A strong candidate for TNT soil-contamination within Greece, is the military base/airport of Maleme in Crete. While soil sampling was in progress new routes of trace analysis...

The soil adsorption behaviour of atrazine and its photodegradation intermediate 4,6-diamino-2-chloro-1,3,5- s-triazine (I), was evaluated by measuring partition coefficients on five representative European topsoils using classical batch experiments. From this study, (I) appears to be less...

The work deals with coal combustion in a pilot-plant fluidised bed (7 cm i.d.) under atmospheric conditions. The aims are to capture and analyse qualitatively as well as quantitatively the volatile polycyclic hydrocarbons emitted by using coal as energy source under various combustion conditions...

Chlorination of drinking water leads to the formation of a variety of Disinfection By-Products (DBPs) that may have adverse health effects on humans. Research on this subject has been continued and new epidemiological and toxicological studies have been conducted. This review summarizes factors...

The photocatalytic degradation of protocatechuic acid, a biorecalcitrant polyphenolic compound typically found in olive processing and wine distillery waste waters, has been investigated in aqueous heterogeneous solutions containing semiconductor powders (TiO2, ZnO) as photocatalysts, both in the...

An experiment was conducted in a greenhouse located in Agrinion, Greece, in order to study the effect of the treated municipal wastewater (TMWW) on the soil heavy metal interactions, in comparison to ordinary well irrigation water, denoted as control. The ultimate aim was the establishment of sound...

During recent years special attention has been paid to various environmental impacts from aircraft emissions. The effects become more important considering the present situation in the air traffic sector and future expectations for higher air travel demands. In this paper the evolution of aircraft...
