Hydrodynamic and water quality modelling of Southern Evoikos Gulf, Greece

by

Stamou A.I., Noutsopoulos C., Pipilis K.G., Gavalaki E. and Andreadakis A.

General

A mathematical model is presented, consisting of a two-layer, finite difference hydrodynamic submodel and a compartmental water quality sub-model. The model is calibrated with field data. Then, it is applied to Southern Evoikos Gulf, an open coastal water body of particular ecological significance...

Modeling of Anaerobic Digestion - A Review

by

Lyberatos G. and Skiadas I.V.

General

Anaerobic digesters often exhibit significant stability problems, that may be avoided only through appropriate control strategies. Such strategies require, in general, the development of appropriate mathematical models, which adequately portray the key processes that take place. This paper reviews...

Relation between air pollution episodes and discomfort index in the greater Athens area, Greece

by

Paliatsos Ath. and Nastos P.

General

An attempt is made for a first general study of the relation between high/very high concentrations of nitrogen dioxide and ozone with the discomfort index (DI) values. The nitrogen dioxide data of «Patision» station and ozone data of «Liosia» and «Marousi» station have been analysed. The relation...

Winter Southern wind flow and air pollution episodes over Athens, Greece

by

Kassomenos P.A., Lykoudis S. and Kallos G.

General

The greater area comprising the Attica peninsula and the Saronic Gulf is greatly influenced by various local circulation types. During winter months, moderately high air pollutants concentrations are observed when the prevailing condition is either stagnant or a weak southern flow. The case studied...

Organic by-products of Drinking Water Chlorination

by

Nikolaou N., Kostopoulou M. and Lekkas T.D.

General

Chlorination of drinking water leads to the formation of a variety of Disinfection By-Products (DBPs) that may have adverse health effects on humans. Research on this subject has been continued and new epidemiological and toxicological studies have been conducted. This review summarizes factors...

Analysis of the 11-year Record (1987-1997) of Air Pollution measurements in Athens, Greece. Part I: Primary air pollutants

by

Kalabokas P.D., Viras L.G. and Repapis C.C.

General

A climatological analysis of atmospheric concentrations of primary air pollutants in Athens, Greece, is presented for the 11-year period 1987-1997, since the automated local air pollution network operating by the Ministry of Environment started to record all conventional pollutants. The...

Analysis of the 11-year Record (1987-1997) of Air Pollution measurements in Athens, Greece. Part II: Photochemical air pollutants

by

Kalabokas P.D., Viras L.G. and Repapis C.C.

General

This paper deals with the analysis of atmospheric concentrations of secondary photochemical air pollutants in Athens for the 11-year period 1987-1997. Photochemical pollution, which seems to be the most serious air pollution problem in Athens, is originating mainly from the transformation of car...

Modeling atmospheric aerosol using thermodynamic arguments - A Review

by

Pilinis Chr.

Air pollution and health

Atmospheric aerosols have been implicated in human health effects, visibility reduction in urban and regional areas, acidic deposition, and altering the earth’s radiation balance. A major goal of scientific research for the last fifteen years has been the development of the necessary models, using...

Air-vegetation-soil partitioning of toxic chemicals in environmental simulation modeling

by

Tsiros I.X., Ambrose R.B. and Chronopoulou-Sereli A.

General

Accumulation of airborne pollutants in vegetation is an important initial step in the uptake process of the terrestrial food web, providing direct and indirect routes by which biota and, eventually, humans are exposed to chemicals. A set of algorithms for estimating atmospheric pollutant...

Production of low aromatics and low sulfur diesel in a hydrodesulfurization (HDS) pilot plant unit

by

Lappas A.A., Budisteanu R., Drakaki K. and Vasalos I.A.

General

The present work investigates the hydrotreating process of a diesel in order to achieve lower sulphur and aromatics content. The entire work was performed in a Hydrodesulphurization (HDS) pilot plant unit located in Chemical Process Engineering Research Institute (CPERI). For the tests, a commercial...
