Microbial community dynamics in a permeable reactive barrier using real-time PCR technique
© Aristotle University of Thessaloniki (6/2009)
This study was conducted with the application of polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), and real-time quantitative polymerase chain reaction (real-time PCR) molecular biotechnology for monitoring the permeable reactive barrier (PRB) in the relation with BTEX (benzene, toluene, ethylbenzene, and p-xylene) decomposition efficiency and the distribution of microbial community.

Determination of pesticide residues in river water of Aliakmonas in the region of Imathia (N. Greece) by means of solid phase extraction disks and gas chromatography

A solid-phase extraction (SPE) method was applied to an extended monitoring survey of selective pesticides for a period of 12 months in water of Aliakmonas River (in region of Imathia). The aim was to determine their concentrations and seasonal variations.

R.E.MO.S. network in lignite mines in Western Macedonia, Greece. Assessment of the results for the year 2008

Lake Kastoria is a very important aquatic ecosystem, situated in the Region of Western Macedonia, Greece. A six years monthly monitoring program (2002-2008) in five Sampling Stations in the Lake area is operating by the Municipality of Kastoria.

An analytical method for determination of haloacetamides in chlorinated water
© Aristotle University of Thessaloniki (6/2009)
Chlorination by-products (CBPs) are produced after chlorine reaction with organic matter that is naturally present in water. Haloacetamides are CBPs that contain nitrogen, an element that is present in precursors known as humic acids. Haloacetamides are among the less studied world wide CBPs and the most polar organic compounds.

Disinfection by-products in chlorinated drinking waters in Volos area, central Greece
© Aristotle University of Thessaloniki (6/2009)
The occurrence of trihalomethanes (THMs) and haloacetic acids (HAAs) in chlorinated drinking water at different points of the water distribution systems of Volos region (east coast of central Greece) was examined for a period of two years. Determination of THMs was performed after liquid-liquid extraction with pentane and quantification by gas chromatography with electron capture detection (ECD).

Treatment and control of industrial waste water effluents containing hexavalent chromium

In this work the method for the treatment of industrial waste waters effluents containing hexavalent chromium in three companies during process of treating metal surface with chromic acid is described.

Evaluation of the trophic state of Ziros lake, NW Greece
© Aristotle University of Thessaloniki (6/2009)
Lake eutrophication has been a major problem for decades. It involves a change in lake status from a macrophyte-dominated clear water state to a phytoplankton-dominated turbid state, with detrimental effects to the ecosystem. The eutrophication process in lakes can be evaluated by determining the limiting nutrients and by calculating trophic state indices.

Treatability studies for an organized industrial district (OID) effluent in Bursa, Turkiye for agricultural irrigation purposes
© Aristotle University of Thessaloniki (6/2009)
The reusability of the effluent from the wastewater treatment plant of an organized industrial district in the northwest of Turkiye was investigated in this study. Chemical precipitation and ion exchange methods were used to obtain a water reusable for agricultural irrigation purposes.

Formation of THMs during typical dissolved organic nitrogen alanine chlorination in drinking water
© Aristotle University of Thessaloniki (6/2009)
Owing to its low cost, chlorine is globally the most used chemical oxidant for drinking water disinfection. However, there is an unintended consequence of disinfection, the generation of chemical disinfection byproducts (DBPs), especially trihalomethanes (THMs). Dissolved organic nitrogen (DON) as the important precursor of DBPs is of current concern. As alanine (Ala) occurs in much source water, we studied formation pathways for THMs during chlorination of model alanine.
