Extended suspect screening to identify organic micropollutants and their transformation products as potential markers of wastewater contamination in riverine and coastal ecosystems

ČELIĆ M., JAEN A., BRICEÑO-GUEVARA S., RODRIGUEZ-MOZAZ S., (Corresponding) GROS M., PETROVIĆ M.
Topic: 
Emerging pollutants
In this study, a comprehensive suspect screening of organic micropollutants (MPs), and some of their transformation products (TPs) and metabolites, was performed in waste, river and coastal waters from the Ebro Delta region (Catalonia, Spain). For this purpose, an automated suspect screening...Read more

Screening of polar pesticides in groundwater in Hebei Province, China

Huang Y., (Corresponding) Rao Z., GUO X., YANG Z., LIU C., SHI Z.
Topic: 
Soil and groundwater contamination and remediation
As a big agricultural country,China has a relatively high pesticide usage in unit area , which is three times higher than developed countries. About 80% of pesticides directly enter the soil and the water through leaching or surface runoff during the usage of pesticides. In particular, some of the...Read more

A nine-year study on the temporal changes of licit and illicit drug use patterns as revealed from the chemical analysis of influent wastewater from the wastewater treatment plant of Athens

Galani K., Alygizakis N., Borova V., (Corresponding) Thomaidis N.
Topic: 
Emerging pollutants
Daily flow-proportional composite influent wastewater was collected from the Wastewater Treatment Plant (WWTP) in Athens during a nine-year sampling campaign (2010-2019). Analytes in influent wastewater are markers of the consumption and the exposure of the chemicals in the population. Wastewater...Read more

NORMAN Non-target screening (NTS) prioritisation scheme for ranking thousands of contaminants of emerging concern in effluent wastewater collected from Europe

(Corresponding) Alygizakis N., Dulio V., Von der Ohe P., Slobodnik J., Thomaidis N.
Topic: 
Emerging pollutants
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...Read more

Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS

(Corresponding) Rao Z., liang m., Liu L., Gong J., Zhu T.
Topic: 
Emerging pollutants
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...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

Untargeted screening analysis for mycosporines and mycosporine-like amino-acids in algae by mass spectrometry

(Corresponding) Parailloux M., Godin S., C.M. Fernandes S., Lobinski R.
Topic: 
Environmental biotechnology and bioenergy
Mycosporines and mycosporine-like amino acids have been described as natural sunscreens and antioxidant compounds presenting a great potential for health and cosmetic applications. Herein, an untargeted screening approach for mycosporines and mycosporine-like amino acids (MAAs) was developed by the...Read more

Evaluation of the human exposure to a broad spectrum of organic chemicals and the potential use of sewage sludge to prioritize hazardous substances

(Corresponding) Gil-Solsona R., Nika M., Alygizakis N., Bustamante M., Villanueva C., Foraster M., Gómez-Roig M., Llurba-Olive E., Sunyer J., Dadvand P., Thomaidis N., (Corresponding) Gago-Ferrero P.
Topic: 
Environmental exposures and human health
Chemicals are part of our daily lives, and we are exposed to multiple chemicals through multiple pathways. Relevant scientific evidence contributing to regulation of hazardous chemicals requires a holistic approach to assess simultaneous exposure to multiple compounds. In this sense, recent...Read more

Development of a non-target screening workflow for the evaluation of micropollutants fate during oxidation processes

(Corresponding) Huynh N., Le Roux J., Guyot J., Moilleron R.
Topic: 
Emerging pollutants
Non-target screening (NTS) is of great interest for environmental monitoring because it enables the screening of numerous pollutants, including unknown products. However, methods to identify unknowns are still time-consuming and only deal with a limited portion of the signal. The objective of this...Read more
