LCA as a tool for environmental management: a life cycle inventory case study from the Greek market
General
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...
An environmental database for the status of freshwater in Greece
General
An environmental database has been created, recording water bodies at a national level and assembling relevant data collected by various public services and institutions in charge of water resources management and research in Greece. Data consists of physico-chemical parameters, geomorphological...
ENVIRON: Environmental Impacts from Advanced Communications - Evidence from an Input-Output Theory
General
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...
Hydrochemical and Ecological Quality Assessment of a Mediterranean River System
General
In order to explore the complex interrelations among the factors and processes that determine a rivers’ hydrochemical and biological quality, statistical techniques were applied to a variety of hydrochemical, petrologic, biological, habitat, hydrological and morphologic data from 16 sites of the...
Spatial prediction of two soil properties using topographic information
General
The objective of this study was to determine whether the use of the co-regionalization of the distanceto- river topographic variable with the soil properties topsoil clay and sand can improve their mapping. The interpolation techniques: ordinary kriging, kriging combined with regression (two models)...
Coastal modelling with a GIS bathymetric module
General
A 3D hydrodynamic/pollutant transport model was used to simulate the currents and pollutant transport in coastal areas. The bathymetric and shoreline data was provided to the model via a GIS module that operates in the ArcView GIS environment. The module is efficient and capable of generating...
Sorption-desorption isotherms of dyes from aqueous solutions and wastewaters with different sorbent meterials
General
The ability of activated carbon and different low-cost by-products and waste material as sorbents to remove various reactive dyes from aqueous solutions and wastewaters was investigated. All aqueous dye solutions contained 2,000 mg l-1 NaCl, to mimic real dye wastewater. Batch kinetic and isotherm...
The importance of mercury determination and speciation to the health of the general population
General
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...
On the relation between sea surface and lower temperature over the northern hemisphere
General
In this work the covariability of sea surface and lower troposphere temperatures (SST-AT) is investigated for winter (DJFM) and summer (JJAS), over the whole northern hemisphere, by utilizing monthly anomalies in grid boxes for a 22-year period. Air temperature variations in the lower troposphere...
Degradation of phenol in wastewater using anolyte produced from electrochemical generation of brine solution
General
This paper presents the degradation of phenol in wastewater using anolyte, which is generated from electrochemical activation process. Anolyte consists of reactive ions and free radicals, which contribute to its oxidizing behavior. The optimum conditions, which facilitate a complete degradation of...
