Temporal variability of disinfection by-products concentration in urban public water system
General
The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major...
Effect of calcium cyanamide on pathogenic escherichia coli during mesophilic composting and impact on composting process
General
The objective of the study was to determine the effect of CaCN2 on pathogenic E. coli as an antimicrobial agent and its impact on composting progress as an amendment in dairy cow manure based mixtures composted at laboratory scale. The changes in physical parameters, chemical parameters and...
Overview of the Temporal Variation of PM10 Mass Concentrations in the two Major Cities in Greece: Athens and Thessaloniki
General
Literature reports have indicated that Particulate Matter (PM) concentrations in the atmosphere over the major urban centres of Greece are high compared to other European cities of the same size. The great majority of these reports are based on measurements that have been conducted over a limited...
Medical geochemical investigations in taking precautionary measures against diseases. Protection and human health
General
A considerable number of diseases are directly related to environmental impact. Toxic metals such as Hg, Pb, Cd, and As may damage significantly the human health when they exceed certain levels in the body. For example specific precautions should be taken for the diet of pregnant women and the...
Hydrochemical Characteristics and Groundwater Quality in the Island of Lesvos, Greece
General
The hydrochemical characteristics of groundwater in the island of Lesvos, Greece, were studied based on chemical analyses of groundwater samples collected from 30 locations covering all the island’s major aquifers hosted in different lithological formations. The Plagioclase dissolution was found to...
Assessment of heavy metal contamination in soil and wheat (Triticum Aestivum L.) plant around the Corlu–Cerkezkoy highway in Thrace region
General
Pollution caused by traffic activities is increasingly becoming a great threat to human health in the region of Thrace in north-west of Turkey. Thirty six soil and plant samples were collected from the vicinity of Çorlu–Çerkezköy Highway. The samples were taken at distances of, 1, 25, 50, 100, 250...
Effect of Temperature on Fenton oxidation of young landfill leachate: Kinetic Assessment and Sludge Properties
General
Treatment of young landfill leachate, collected from municipal solid waste site of city of Konya, was investigated by using the Fenton process. The leachate itself showed the characteristics of pH 7.25, COD 38.2 g L-1 and BOD5 22 g L-1. Ratio of BOD5 to COD with 0.58 indicates that leachate can be...
Environmental Improvement of Alexandria’s Wastewater Treatment Plants Using Life Cycle Assessment Approach
General
Improving the treatment efficiency of a primary wastewater treatment plant(WWTP),in Alexandria, Egypt,was studied.In order to improve the treatment efficiency of the plant, different improving scenarios were proposed and evaluated. The improvement scenarios are: scenario 1,use of engineered wetland...
Natural organic matter fractionation along the treatment of water for human consumption
General
The main objective of this study was to characterize the organic matter present in raw water and along the treatment process, as well as its seasonal variation. A natural organic matter fractionation approach has been applied to Lever water treatment plant located in Douro River, in Oporto (Portugal...
Competitive effects of herbaceous species on water potential and growth of quercus ithaburensis ssp. Macrolepis seedlings
General
A noticeable decline of Quercus ithaburensis ssp. Macrolepis, a typical mediterranean species, has been recorded in the past few decades throughout Greece. The triggers were mostly human influences and specifically illegal cuttings, wildfires, and overgrazing. Regeneration and future management of...
Solar assisted photo fenton for cost effective degradation of textile effluents in comparison to AOPS
General
Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD...
Changing mediterranean environment: irrefutable evidence from pre-industrial, unpublicised scenes contemporary with a mission (1786-1787) in the Levant
General
This paper provides an introduction to one hundred thirty one, pre-industrial, unpublicised Mediterranean scenes kept in Oxford, which constitute valuable evidence of changing environment. The largely unknown and unpublished paintings witness environmental wilderness and the cultural landscapes of...
Regional climate change scenarios for Greece: future temperature and precipitation projections form ensembles of RCMs
General
The potential regional future changes in seasonal (winter and summer) temperature and precipitation are assessed for the greater area of Greece over the 21st century, under A2, A1B and B2 future emission scenarios of IPCC. Totally twenty-two simulations from various regional climate models (RCMs)...
Development of a regional model for hydropower potential in western Greece
General
A regional model was developed in the present study for the determination of the flow duration curve at ungaged catchments, in western and northwestern Greece, which is a hydrologically homogenous region. A flow duration curve indicates the water availability at a site and is important for the...
Neural network estimation of the scour cone geometry around outlet in the pressure flushing
General
When flushing carry out as pressure condition, a scour cone is performed around the outlet. As the flow around the outlet in the pressure flushing is three dimensional, therefore that it is difficult to establish a general empirical model to provide accurate estimation for scour cone volume and...
Thermal comfort estimation in relation to different orientation in mountainous regions in Greece by using artificial neural networks
General
This study focuses on the estimation of thermal comfort conditions in a high alt. site (1455 m) in Apodotia (MA), Greece, by using the MLP neural network model. This estimation is based on the air temperature (t) and relative humidity (f) data of the middle (1078-1163 m) and of the low altitude...
Ammonia removal from fertilizer plant effluents by a coupled electrostatic shielding based electrodialysis / electrodeionization process
General
Electrically and ionically conducting graphite powder beds interposed between the anode and cathode inside an electrolytic setup are used as intermediate bipolar electrodes. The beds cause electric field discontinuity by eliminating the applied electric field locally within their mass and act as...
