Current status of the metal pollution of the environment of Greece - a review
General
ABSTRACT Pollution from metals and metalloids of the environment of Greece seemed to attract many researchers and elemental pollutants in air, soil and water have been determined and studied systematically during the last decade. The most recent of these studies, concerning the last five years (2003...
Use of selected advanced oxidation processes (AOPs) for wastewater treatment - a mini review
General
Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater...
Flux enhancement by air dispersion in cross-flow microfiltration of a colloidal system through spiral wound module
General
Enhancement of the permeate flux due to reduction of cake layer resistance by air-liquid twophase flow in a cross flow spiral wound microfiltration membrane has been investigated. Experiments were carried out with two different suspension systems, namely baker’s yeast suspension with a dry mass...
Ultrafine particles (UFP) and health effects. Dangerous. Like no other PM? Review and analysis
General
The goal of the current review is to present and analyze the known information proposed and discussed the last few years about UFP and their possible health effects. It includes references from 1992 to 2008. It also includes references from some fundamental studies in the 1970's and 1980's. The...
Integrated urban water modelling using Aquacycle model
General
The traditional approach to urban water management is primarily based on a supply-oriented approach, where water follows a one-way path from supply to a single use, treatment and then discharged to the environment. The wide acknowledgement of the need to shift towards more sustainable practices has...
Assessment of clustering algorithms in discriminating eutrophic levels in coastal waters
General
Cluster analysis has been used widely as a tool for assessing eutrophic trends in coastal waters. The efficiency of clustering in discriminating between oligotrophic, mesotrophic and eutropic sites, depends on the variables used, the distance measure and the clustering algorithm applied. In the...
Removal of COD from Oil Recovery Industry Wastewater by the Advanced Oxidation Processes(AOP) Based on H2O2
General
The combinations of H2O2/Fe+2, UV/H2O2/Fe+2 and UV/H2O2 process were investigated on treatment of oil recovery industry wastewater. Treatment of oil recovery industry wastewater, a typical high pollution strength industrial wastewater (chemical oxygen deman (COD): 21000 mg l-1, biological oxygen...
CO2 control by means of the increased penetration of diesel passenger cars in Finland
General
One efficient way to control the CO2 emissions from the transport sector is the replacement of gasoline passenger cars by Diesel ones, which emit less CO2. This can be more effective in Finland, where the Diesel penetration is only 13.6%, which is very low compared to the other member countries of...
Do the maxima of air pollutants coincide with the incedence of childhood asthma in Athens, Greece?
General
In the present study an assessment of the influence of the ambient air pollution on the incidence of the Childhood Asthma Admissions (CAA) is attempted by using cross spectrum analysis. The medical data concern the hospital registries of the three main Children’s Hospitals of Athens for the 14-year...
Enhancement of photocatalytic activity of TiO2 nanoparticles by silver doping: photodeposition versus liquid impregnation methods
General
Silver doped TiO2 nanoparticles have been prepared by liquid impregnation (LI) and photodeposition (PD) methods and characterized by surface analytical methods such as scanning electron micrographs (SEM) and X-ray diffraction (XRD). The photocatalytic activity of silver doped TiO2 was tested by...
