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

Characterization of Natural Organic Matter and Disinfection By-products Formed After Chemical Disinfection of Water

(Corresponding) Postigo C., (Corresponding) Andersson A., Mourad H., Bastviken D., Gonsior M., Schmitt-Kopplin P., Gago-Ferrero P., Ahrens L., Ahrens L., Wiberg K.
Topic: 
Emerging pollutants
Chemical disinfection of water has been commonly applied to protect public health from waterborne infectious diseases. Chemical disinfectants are strong oxidants that react with the building blocks or alter the metabolism of pathogenic organisms, killing them as the final consequence. These...Read more

Detection of cyanobacterial toxins and oligopeptides from the Polemidia Dam in Cyprus

(Corresponding) Keliri E., Antoniou M., Edwards C., Mazur-Marzec H.
Topic: 
Emerging pollutants
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...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
