Development and validation of a novel analytical protocol for the simultaneous determination of organic micropollutants in biota specimens by GC-APCI-QToF MS.

Orfanioti A., Gkotsis G., Nika M., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

During the last decades, overwhelming evidence has shown that various xenobiotic compounds have been released into the environment, due to anthropogenic activities. The term “Persistent Organic Pollutants (POPs)” has been established for organic chemicals that are resistant to degradation,...Read more

Assessment of the pH-effect on the toxicity, uptake & biotransformation of Fluoxetine in Zebrafish (Danio rerio) embryos by LC-ESI-QTOFMS

Panagopoulou E., Tzepkinli V., Damalas D., Aalizadeh R., Schweizer M., Schulze P., Kohler H., Von der Ohe P., Triebskorn R., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

Over the recent decades, there is great interest from the scientific community in emerging contaminants, such as pharmaceuticals. Previous studies have demonstrated that they are ubiquitous in aquatic ecosystems, mainly due to insufficient removal by wastewater treatment plants (WWTPs). In light of...Read more

Investigation of the influence of environmentally relevant pH values in the toxicity of the b-blocker Metoprolol in zebrafish (Danio Rerio) embryos through toxicokinetic approaches (uptake, bioaccumulation, and biotransformation)

Tzepkinli V., Panagopoulou E., Damalas D., Aalizadeh R., Schweizer M., Hebel J., Kohler H., Von der Ohe P., Triebskorn R., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

Recently, the release of emerging contaminants into the aquatic ecosystems has become an issue of concern among scientists since some of them are frequently detected in the environment at levels that may cause harm. One of the main categories of emerging contaminants is the human and veterinary...Read more

Start-up of full-scale UASB - verftical flow constructed wetland for domestic wastewater treatment

(Corresponding) Malamis S., Statiris E., Seintos T., Koukoura A., Mamais D., Noutsopoulos C., Masi F., Rizzo A., Bresciani R.

Topic:

Wastewater treatment

This work examined the start-up of a full-scale upflow anaerobic sludge blanket (UASB) - vertical flow constructed wetland (CW) for domestic wastewater treatment. The UASB reactors were inoculated with sludge originating from an industrial anaerobic reactor and the start-up period due to the slow...Read more

Selenate uptake by Chlamydomonas reinhardtii Algal Cells, its Transformation and its Effect on Membrane Lipid Profiles

Zkeri E., Mavrakis E., Panagou G., Grafanaki S., (Corresponding) Pergantis S., Lydakis-Simantiris N.

Topic:

Heavy metals in the environment

While selenium (Se) has been demonstrated to be essential for the optimal growth of freshwater microalgae Chlamydomonas reinhardtii [1], exposure to elevated concentrations of selenite (Se[IV]) or selenate (Se[VI]), the two major aqueous forms of Se, induce cell toxicity[2]. In this study,...Read more

Water quality monitoring in the Dnieper River Basin using advanced analytical methodologies

Diamanti K., Nika M., Alygizakis N., Kostakis M., Koupa A., Oswald P., Cirka L., Slobodnik J., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

The Dnieper River Basin is the main freshwater resource for Ukraine. Despite being used as source for drinking water, its water quality does not always meet the environmental standards. The basin is highly affected by regional and transboundary (from western Russia and Belarus) anthropogenic...Read more

Analysis of the extreme water phenomenon (hydrological drought) in the small river basins in NE Romania

(Corresponding) PAVELUC L., GROZAVU A., HUTANU E., MIHU-PINTILIE A.

Topic:

Hydrology and water resources

This paper presents an analysis of one of the climatic dangers experienced in recent times is the high intensity of the drought phenomenon on small rivers in NE Romania that affects society and ecosystems. As a case study, it is intended to identify statistically significant trends in the minimum...Read more

Disinfection byproducts and related compounds in the coastal zone: a preliminary compilation

Alexandropoulou S., (Corresponding) Nikolaou A., Vagi M.

Topic:

Marine environment and coastal management

Disinfection byproducts (DBPs) are formed whenever disinfectant ingredients contact organic matter. Due to widespread increase in production and use of disinfectants and antiseptics, the presence of their ingredients in coastal environments is increasing. However, very limited scientific literature...Read more
