[CEST2019_00911] Detection of cyanobacterial toxins and oligopeptides from the Polemidia Dam in Cyprus
by Keliri E.,Antoniou M.G., Edwards C., Mazur Marzec H.

Cyanobacterial harmful algal blooms are becoming more spatially persistent worldwide. The formation and release, through cell-death and/or excretion, of bioactive metabolites (cyanotoxins) is comprising a reoccurring concern to environmental protection agencies. Cyanotoxins can negatively impact mammalian health in various ways by causing cytotoxicity, hepatotoxicity, and neurotoxicity. Besides conventional toxins some genera can produce an array of oligopeptides characterized as microginin, cyanopeptolins, and aeruginosins.

[CEST2019_00524] Fast and comprehensive analysis of major use antibiotics by UHPLC-High Resolution and High Mass Accuracy hybrid Linear Ion-Trap-Orbitrap Mass Spectrometry
by Kalampoka M., Boti V., Sakkas V., Albanis T.

In this study, antibiotics of multiple classes (sulfonamides, quinolones, penicillins, macrolides, tetracyclines, pyrimidines) were selected to be accurately detected with modern chromatographic systems based on hybrid mass analyzers. For that purpose 13 antibiotics of major use were separated and detected with ultra-high performance liquid chromatography (UHPLC) high-resolution LTQ/Orbitrap mass spectrometry.

[CEST2019_00968] Biological activity of flufenamic acid and synthesized derivatives (PFCs) that may occur in the environment
by Šilha D., Šilarová P., Weidlich T.

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 negative effect on humans and the entire ecosystem. PFCs include, for example, flufenamic acid (antipyretic). The aim of the study is to verify the biological activity of flufenamic acid and derivatives prepared from this initial compound by organic synthesis.

[CEST2019_00974] Determination of Emerging Contaminants in Surface Water Resources of EYDAP following wide-scope Target and Non-Target Screening
by Nikolopoulou V.I., Nika M.C., Aalizadeh R., Miskaki P., Kaloudis T., Deftereos N.T., Avagianos C., Thomaidis N.S.

The aim of the study was to perform extended monitoring of emerging contaminants in the water samples from three reservoirs of drinking water of EYDAP, Evinos, Mornos and Marathonas. Solid-Phase Extraction (SPE) by mixed-mode sorbent was used during the sample preparation to ensure the extraction of compounds with a wide range of physicochemical properties and very low limits of detection.

[CEST2019_00979] Influence of pH on the toxicity, uptake and biotransformation potential of citalopram in zebrafish (Danio rerio) embryos
by Damalas D.E., Panagopoulou E., Aalizadeh R., Schweızer M., Heıd C., Köhler H., Ohë P.V.D., Triebskorn R., Thomaidis N.S.

The contamination of the aquatic environment has raised concerns in the scientific community and regulatory authorities. Given the large number of xenobiotics, for most of them there is a striking deficit in the literature concerning their adverse effects on aquatic organisms. Citalopram (CTR) is a worldwide highly consumed antidepressant which has demonstrated incomplete removal by conventional wastewater treatment, hence resulting in the contamination of aquatic ecosystems. Consequently, it is urgent to evaluate its potentially toxic effects on aquatic organisms.

[CEST2019_00088] Occurrence and spatiotemporal variability of sunscreen agents along the polish part of the Baltic Sea coast
by Astel A., Stec M., Astel K.

UV-filters accumulate in tissues of aquatic organisms and induce negative effects on fertility and reproduction. Since they are “new emerging pollutants” general monitoring programs are rare and mainly conducted in touristic places, where high temperatures are recorded throughout the year (Spain, the Gulf of Mexico, the Mediterranean coast). This study is focused on benzophenones and derivatives of camphor.

[CEST2019_00290] Triclosan occurrence in European Sewage Treatment Plants and risk assessment for the European rivers
by Thomaidi V.S., Matsoukas C., Stasinakis A.S.

The purpose of this study was to estimate the environmental risk associated with the existence of triclosan (TCS) released from municipal wastewater in the European rivers. A literature review was held to record the concentration levels of TCS in effluents of European Sewage Treatment Plants (STPs), while toxicity data was collected for aquatic organisms (algae, Daphnia magna and fish). Risk assessment was based on both Risk Quotient (RQ) methodology and Monte Carlo simulation.
