Removal of hexavalent chromium from electroplating wastewater by electrocoagulation with iron electrodes
General
The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial...
Under climatic change, soil microbial community and variables relating to N-cycle are modulated by changes in the upper limit temperature
General
The effect of temperature increase and more specifically its upper and low level correlates on soil microbial biomass, activity and N-cycle variables was studied in a Mediterranean shrubland. Experimental manipulation succeeded in establishing three treatments which, in comparison with the monthly...
Plant biomonitoring: impact of urban environment on seasonal dynamics of storage substances and chlorophylls of Oleander
General
In the present study seasonal changes of chlorophyll content and storage substances related to the metabolic response of the widespread, evergreen plant oleander (Nerium oleander) to air pollution were investigated. Mature leaves of oleander shrubs, grown at five sites of differing levels of air...
Application of sludge, organic solid wastes and yard trimmings in aerobic compost piles
General
The effects of different mixture ratios of sewage sludge (SS), organic fraction of municipal solid waste (OFMSW) and yard trimmings (YT) on the performance of composting process were investigated in this study. The high water content and the proper carbon/nitrogen ratio make sludge ideal for this...
Temporal and spatial scales of lake processes. Part 1: physical and ecological scales, non-dimensional parameters and flow regimes
General
Scaling concepts, related to basic physical transport and mixing processes and other ecological aspects in lakes, are reviewed in an ecohydrodynamic perspective; the length and time scales as well as the non-dimensional parameters governing the various flow regimes and relevant to these processes...
Temporal and spatial scales of lake processes. Part 2: interaction of physical and ecological scales and application of scaling concepts to greek lakes
General
The temporal and spatial scaling concepts related to basic physical and ecological lake processes and the associated non-dimensional parameters that govern the various flow regimes, developed in lakes and reviewed in Part 1 of our companion paper (Papadimitrakis, 2011), are applied to lakes Pamvotis...
Dehalogenation of polychlorinated biphenyls (PCB) by nucleofile reactants at the presence of ionic liquids and under application of microwaves
General
Laboratory-scale experiments were performed in order to examine the effect of microwave field on the effectiveness of KPEG method (nucleophilic substitution of the chlorine atoms in a molecule of PCBs by alkaline polyethylene glycol PEG) in the removal of PCBs from highly contaminated mineral oils...
An environmental health information system - assessment of the situation in Greece
General
Presented are the results, with emphasis on the situation in Greece, of the ENHIS-2 project “Establishment of Environment and Health Information System Supporting Policy Making”. The information system is based on a set of Environmental Health Indicators developed and updated by the project...
Adsorption capacity of GAC pilot filter-adsorber and postfilter- adsorber for individual THMs from drinking water, Athens
General
Trihalomethanes are a major class of chlorination by-products in drinking water. They are formed when chlorine reacts with bromide (Br-) and natural organic matter (NOM) in source waters. Toxicology studies have shown all THMs to be carcinogenic or to cause adverse reproductive or developmental...
Environmental sensitivity index mapping of Lagos shorelines
General
Environmental Sensitivity Index (ESI) mapping of Atlas Cove, Lagos, Nigeria was carried out with the objective of producing an Environmental Analysis Index map of the shorelines. The study integrated methodologies developed by National Oceanic and Atmospheric Administration (NOAA) and Nigerian Oil...
