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...
Fourier Analysis of the mean monthly Nox Concentration in the Athens basin
General
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...
Regression Analysis and urban air quality forecasting: an application for the city of Athens
General
Air pollution forecasts in major urban areas are becoming a problem concerning the day to day environmental management for city authorities. This paper describes the development of an application to forecast the peak ozone levels with the aid of meteorological and air quality variables, in the...
Water saving and yield increase of sugar beet with subsurface drip irrigation
General
This study was conducted to evaluate the surface and subsurface drip irrigation (SDI) application effects on sugar beet crop performance, under two levels (100% and 80%) of water application depth. The experimental design was a split plot with four replications. Laterals were set every second crop...
