Influence of Diphenyloxide Disulfonate Surfactants on Biodegradation of Hydrocarbons

by

Rouse J. D., Osamu Hirata and Kenji Furukawa

General

Testing was conducted with anionic diphenyloxide disulfonate (DPDS) surfactants (C12 and C16 alkyl moieties) with naphthalene in aqueous systems and phenanthrene in soil systems to investigate the influence of these surfactants on biodegradation of hydrocarbons. A potential for enhancement in the...

The ways to prevent formation of water-soluble fluorine compounds when producing phosphate fertilizers

by

Molchanov P.A., Denanov G.A., Podobna Y.Y. and Korniychuk T.K.

General

Natural phosphate raw materials contain up to 3.5% of fluorine. In reprocessing natural phosphate raw material 30 - 100 % of fluorine emits into the environment as toxic compounds. The acid is used for decomposing the carbon dioxides that are contained in raw materials. The way and technology of...

Setting priorities for wildfires suppression policy in Greece, using a relation between yearly burned areas and recovery time

by

Hadjibiros K.

General

In the Mediterranean region, fire is a natural factor, which contributes in the shaping of landscape and the preservation of a high degree of biodiversity. However, often repeated burning has negative impacts on the forested landscapes. When the processes of natural or artificial regeneration are...

Using GAC to Control THMs in drinking water, an experimental study at the Athens Water Works and an economic evaluation of the method

by

Koumenides K., Lekkas D.F. and Xylourgidis N.

General

An experimental study has been carried out in an attempt to verify the efficiency of GAC (granular activated carbon) in removing THMs (trihalomethanes), and in particular CHCl3, CHCl2Br, CHClBr2 and CHBr3 from drinking water. The experiments have been conducted at a pilot scale filtering plant that...

Determination of Heavy Metals in Wet Deposition of Athens

by

Kanellopoulou Helen

General

The concentrations of ten industrial metals (Pb, Cd, Ni, As, Cr, Zn, Fe, Cu, Al and Mn) in 20 samples of rainwater collected at the station of Athens University Campus (AUC) during the cold period 1/10/97 - 31/3/98 were determined. In general, low concentrations were observed. The Spearman...

Water demand and supply analysis using a spatial decision support system

by

Manoli E., Arampatzis G., Pissias Ev., Xenos D. and Assimacopoulos D.

General

A prototype Spatial Decision Support System for the evaluation of water demand and supply management schemes is presented. The water basin is topologically mapped to a network of spatial objects representing the physical entities and their connections. Several GIS functions, which include data input...
