DESIGN OPTIMIZATION OF A POLYMERIC NANOFILTRATION MEMBRANE FOR OLIVE MILL WASTEWATER VALORIZATION PLUS PURIFICATION

(Corresponding) Pulido J.

Topic:

Water and wastewater reuse

The core of the present work was to model and optimize an environmentally friendly nanofiltration (NF) treatment process for two-phase olive mill wastewater (OMW) valorization throughout concentration and recovery of its phenolic fraction and the obtention of a purified permeate stream. A factorial...Read more

Topic:

General

Overwhelming evidence over many decades has shown that many organic compounds have been released in the environment due to anthropogenic activities. The term “chemicals of emerging concern (CEC)” has been established for chemicals, which are not subjected to marketing restrictions and regulatory...Read more

Investigation of the presence of organic micropollutants in biota specimens from the Antarctica ecosystem using state-of-the-art wide-scope target and suspect HRMS methodologies.

Gkotsis G., Nika M., Vasilatos K., Orfanioti A., Athanasopoulou A., Alygizakis N., Oswald P., Slobodnik J., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

The contamination of the aquatic ecosystem with organic micropollutants due to anthropogenic activities, over the last decades, is a well-known issue. Due to the frequent detection of these chemicals in various environmental compartments, they are considered as potential threats to the aquatic...Read more

Development of a novel GC-APCI-QTOFMS methodology for the determination of more than 300 organic compounds in Asopos river water samples

Panagopoulou E., Nika M., Damalas D., Koulis G., (Corresponding) Thomaidis N.

Topic:

General

The site of interest of this study is Asopos river which is located in Sterea Ellada, north of Athens, and passes through areas where 20% of total Greece industrial production takes place. The extensive installation of industries in the area near the river, and the uncontrolled disposal of...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

Screening thousands of emerging contaminants in Asopos river basin by UPLC-QToF-MS

Nikolopoulou V., Nika M., Aalizadeh R., Alygizakis N., (Corresponding) Thomaidis N.

Topic:

General

Monitoring activities over several decades have revealed the ubiquitous presence of organic contaminants in environmental compartments. Asopos river basin, located in Sterea Ellada, has been the focus of many environmental studies over the last decades, mainly due to its geomorphology and the...Read more
