Adsorptive Removal of Marbofloxacin from Milk using Activated Carbons.

GE X., WU Z., KUNZ W., Barge A., (Corresponding) Giancarlo C.

Topic:

Water and wastewater treatment and reuse

The present study aims to remove the residual marbofloxacin (MBX) from milk with activated carbons (ACs) in batch and flow systems to meet the maximum residue limits (MRLs, 0.075 µg mL-1). Different types (granular and powder) and amounts of ACs were studied. In batch mode, 50 mg of commercial...Read more

Biological activity of flufenamic acid and synthesized derivates (PFCs) that may occur in the environment

(Corresponding) Šilha D., Šilarová P., Weidlich T.

Topic:

Emerging pollutants

Polyfluorinated compounds (PFCs) are used in the field of pharmaceuticals, pesticides, impregnating agents, etc. These are predominantly compounds that are difficult to degradate in the environment, and therefore are highly persistent. Many these compounds are known to have toxic effects and thus a...Read more

Influence of antibiotics on Arcobacter-like cells and their biofilm formation

(Corresponding) Šilha D., Švarcova K., Hofmeisterová L.

Topic:

Antibiotic resistanse

Arcobacters belong to Gram-negative bacteria, the rod cells can be slightly curved into the shape or spiral. Their growth is typical in a microaerophilic environment, but some species are able to grow under aerobic or anaerobic conditions. The purpose of this study was to test the in vitro effect...Read more

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

Electromagnetic radiation including G5 frequencies, health effects summary and policy recommendations

(Corresponding) Stein Y.

Topic:

General

5G millimeter wave technology offers advantages: "smart" homes, "smart" cities and autonomic automobiles. The price: a rise of 30-100% in exposure to electromagnetic radiation near citizens' homes and higher exposure levels inside homes. Scientists have declared current...Read more

Determination of more than 2,400 emerging contaminants in apex predators and their prey from European Specimen Banks and Natural History Museums by novel and complementary High Resolution Mass Spectrometry Techniques

Gkotsis G., Alygizakis N., Cincinelli A., Dekker R., Duke G., Glowacka N., Knopf B., Koschorreck J., Martellini T., Movalli P., Nika M., Nikolopoulou V., Rüdel H., Shore R., (Corresponding) Thomaidis N., Treu G., Slobodnik J.

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
