Characteristics of the precipitation pattern are determined for Thessaly region in central Greece by using the Principal Component Analysis (PCA). Mean monthly precipitation data from 75 meteorological stations are used covering a 35 year period (1960-1994). The first two principal components (PCs)...

Zinc oxide nanocrystals were prepared by precipitation method using ZnSO4.7H2O and NaOH as raw materials. The prepared ZnO nanocrystals were characterized by powder X-ray diffraction (XRD). Primary objective was to focus on the influence of inorganic oxidants, metal ions and anions on photocatalytic...

Recent oil tanker accidents in the sea are very serious, not only since they pollute the environment but also because they release heavy oil. The preparation of activated carbon from agricultural waste increases economic return and reduces pollution. On carbonized fibers, sorption capacity for...

Treatability by the electro-coagulation (EC) and electro-Fenton (EF) methods have been applied to the tannery wastewater from an organized industrial region consisting mostly of tannery plants and compared with each other in this study. Iron plates were used as the anode and cathode. Electrical...

Drainage management problems are usually very hard to simulate due to the uncertainty of the hydraulic parameters involved. Fuzzy analysis is one of the available tools that can be used for such problems, involving uncertain data. A fuzzy analysis approach usually involves the consideration of...

During recent years special attention has been paid to various environmental impacts from aircraft emissions. The effects become more important considering the present situation in the air traffic sector and future expectations for higher air travel demands. In this paper the evolution of aircraft...

Energy use in Greek Industry, fuel mix changes and contribution of major sectors from 1960 to 2004 are presented and analysed. Energy related air pollutant emissions are estimated and presented too. Energy use in Industry has shown a growing trend. Residual fuel oil was the predominant energy form...

An experiment was conducted in a greenhouse located in Agrinion, Greece, in order to study the effect of the treated municipal wastewater (TMWW) on the soil heavy metal interactions, in comparison to ordinary well irrigation water, denoted as control. The ultimate aim was the establishment of sound...

Sites co-contaminated with organic and metal pollutants are common and considered to be a more complex problem, as the two components often have a synergistic effect on cytotoxicity. This study investigated the dissipation mechnisms for pyrene in cadmium co-contaminated soil in which maize (ZEA MAYS...

In this paper, we report the joint use of FTIR spectroscopy and two dimensional correlation analysis (2DCORR) applied to the identification of the aggregation pathways of natural organic matter (i.e. humic substance) extracted from marine sediments and in the second case of study, to the comparison...
