[CEST2019_00973] 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
by Gkotsis G., Alygizakis N., Cincinelli A., Dekker R., Duke G., Glowacka N., Knopf B., Koschorreck J., Martellini T., Movalli P., Nika M.C., Nikolopoulou V., Ruedel H., Shore R., Thomaidis N., Treu G., Slobodnik J.

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 monitoring programmes but are candidates for future regulation, due to their frequent detection in environmental samples and their potential hazardous properties (Thomaidis et al, 2012; Gavrilescu et al, 2015; Dulio et al, 2018).

[CEST2019_00975] Wide-scope target analysis of >2,100 emerging contaminants in landfill leachates by LC-QTOFMS and investigation of their potential ecological threat
by Nika M.C., Ntaiou K., Elytis K., Stasinakis A.S., Thomaidi V.S., Gatidoy G., Thomaidis N.

Organic micropollutants are compounds which are normally detected at concentrations up to microgram per liter in the aquatic environment and they are considered to be potential threats to the ecosystem. Some of them have been studied in detail since 1980s and are already included in existing national or international legislative documents, while others are characterized as emerging contaminants (ECs) and no regulations currently require their environmental monitoring.

[CEST2019_00977] Autonontarget: An R Package to Perform Automatic Non-Target Screening
by Aalizadeh R.,Thomaidis N.

Recent advances on Liquid Chromatography-High Resolution Mass Spectrometry (LC-HRMS) has revolutionized identification of new compounds, having various polarity, over various scientific fields especially in the environmental science. The continuous growing of LC-HRMS applications yet increased the “peak inventories”. This is achieved within three main workflows of “Target”, “Suspect” and “Non-target” screening. Although targeted analysis is the best way to confirm the identification of a compound, it is sometime not practical due to limited access to reference standards.

[CEST2019_00939] Wastewater treatment and emerging contaminants removal in electro membrane bioreactor using self-forming dynamic membranes
by Castrogiovanni F., Borea L., Millanar-Marfa J.M.J., Napodano P., Balakrishnan M., Ballesteros F.C.J., Hasan S.W., Belgiorno V., Naddeo V.

In recent years, the technical-scientific community has been paying increasing attention to the presence of emerging contaminants that are intercepted in surface water and wastewater since these compounds could have harmful effects on human health and on environment too.
Conventional wastewater treatment installations represent a source of pollution from emerging contaminants because they are not designed to remove these compounds from the wastewater in their treatment cycle.

[CEST2019_00971] Development of a novel GC-APCI-QTOFMS methodology for the determination of more than 300 organic compounds in Asopos river water samples
by Panagopoulou E.I, Nika M.C., Damalas D., Koulis G., Thomaidis N.S

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 industrial and agricultural wastes into the river, make the water quality of Asopos questionable. The environmental problem of Asopos river basin is known since 1969, due to the detection of high Cr (VI) concentrations in ground and river water samples with potential carcinogenic effects to human health.

[CEST2019_00972] Screening thousands of emerging contaminants in Asopos river basin by UPLC-QToF-MS
by Nikolopoulou V.I., Nika M.C., Aalizadeh R., Alygizakis N., Thomaidis N.S.

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 extensive industrial activities that take place in this territory. The detection of high Cr(VI) concentrations, causing potential carcinogenic effects, have attracted the attention of media and raised the consciousness of the citizens.

[CEST2019_00803] Dioxin-Like Polychlorinated Biphenyls at Dilijan Landfills (Republic of Armenia)
by Aleksandryan A., Khachatryan A., Bunyatyan Y.

Polychlorinated biphenyls (PCBs) are substances of wide distribution, high toxicity, persistence, and ability to long-distance migration. They are characterized by unique properties: temperature stability; high boiling point; non-combustibility; resistance to chemical and physical influences; high dielectric constants.

[CEST2019_00807] Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS
by Liang M., Liu L., Rao Z., Gong J., Zhu T.

Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS. A total of 45 samples were collected. The targets of the investigation involve multiple types of organic pollutants such as Polycyclic aromatic hydrocarbons (PAHs) and their derivatives, phthalates (PAEs), phenols, anilines, polychlorinated naphthalenes (PCNs), polychlorinated biphenyls (PCBs) et al. The results showed that naphthalene, fluoranthene and phthalates are commonly detected compounds. There are 8 categories of organic pollutants detected.

[CEST2019_00683] NORMAN Non-target screening (NTS) prioritisation scheme for ranking thousands of contaminants of emerging concern in effluent wastewater collected from Europe.
by Alygizakis N.A., Dulio V., Von der Ohe P. , Slobodnik J., Thomaidis N.

Prioritisation of contaminants of emerging concern (CECs) remains a challenging task of primary importance for environmental managers and the scientific community as regards the definition of priority actions for pollution prevention & control and for the allocation of resources to address current knowledge gaps. The NORMAN prioritisation scheme combines the traditional risk-based ranking process with the preliminary application of a decision tree, which allows the allocation of substances into six action categories, based on the knowledge gaps and actions needed to fill them, e.g.

[CEST2019_00551] Pharmaceutical residues in hospital and urban wastewaters: Occurrence, removal and potential risk assessment
by Martinaiou P., Trantopoulos E., Kosma C., Albanis T.

The presence of ten pharmaceutical compounds (bupropion, venlafaxine, mirtazapine, sertraline, citalopram, caffeine, triclosan, carbamazepine, diazepam, clozapine) which belong to different treatment categories was studied in one hospital and three urban WWTPs in north and northwestern Greece. The pharmaceuticals have been selected due to their high usage rate but also because of their proven presence in both wastewater treatment plants and the aquatic environment.

[CEST2019_00537] Optimization of fabric phase sorptive extraction for the determination of selected pharmaceuticals in environmental waters
by Jimenez Holgado C., Vourdas N., Stathopoulos V., Sakkas V.

There is a growing public and scientific concern about the possibility of ecosystem and human health effects from pharmaceuticals in environment. Results have shown that several types of environmental waters (drinking water, groundwater, surface water, treated water) were contaminated by the presence of pharmaceutical compounds including psychiatric drugs. For this reason, it is imperative to develop analytical methods of extraction and pre-concentration to allow for subsequent instrumental analysis of these drugs.
