This paper presents a methodology of evaluating management options for dredged sediments on the basis of an array of characterization tests and gives an example application for the sediments of Piraeus port. A conceptual model is proposed to guide selection among three management options. The model...

Polycyclic Aromatic Hydrocarbons (PAHs) are one of the major categories of pollutants entering the marine environment and finally accumulating in the sediments. Their occurrence raises major concerns for human health, especially during coastal activities (bathing waters, aquaculture, etc), having...

Saltscapes are landscapes with a long lasting salt-making activity, thus embedded with a blend of salt-related characteristics that marked them physically, ecologically, economically, and culturally. This study, based on a broad survey, focuses on the changing atlas of saltmaking business and the...

The Ninth International Symposium on Salt (www.worldsalt2009.com) organized by China National Salt Industry Corporation, China Salt Association and many other salt organizations of the world was held in the Beijing International Convention Center on the 4-7 September 2009. It is the ninth in a...

The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages...

Furrow irrigation is used for row crops. S.C.S., based on a great number of field experiments, under different circumstances and soil families, has developed design equations for furrow irrigation. These equations have been used for steady flow rate or for flow rate with one reduction when the water...

Pollution levels in an urban street-canyon area are determined numerically as part of the European research project OSCAR using the ADREA-HF code. Aim of the modeling is twofold: (i) to investigate the flow-field and carbon monoxide (CO) concentrations in the area and (ii) compare with measurements...

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...
