Cometabolic biotransformation of organic micropollutants under aerobic heterotrophic conditions

(Corresponding) Kennes-Veiga D., Vogler B., Fenner K., Carballa M., Lema J.

Topic:

Emerging pollutants

The role that heterotrophs present in activated sludge play in the removal of organic micropollutants (OMPs) has not been clearly elucidated despite their increasing relevance in the conception of novel wastewater treatment plant technologies. OMPs are often present in wastewaters at concentrations...Read more

The role of microbiological community on organic micropollutants biotransformation in anoxic conditions

(Corresponding) Martinez-Quintela M., Balboa S., Suárez S., Omil F.

Topic:

Emerging pollutants

Information about the biotransformation of organic micropollutants (OMPs) in biological systems is currently scarce, particularly in anoxic environments. A lab-scale reactor was set up to elucidate which is the biological mechanism driving OMPs biotransformation in heterotrophic denitrifying...Read more

Determination of 56 perfluoroalkyl acids and precursors in top predators and their prey from Northern Europe by LC-MS/MS

Androulakakis A., Alygizakis N., Gkotsis G., Nika M., Nikolopoulou V., Bizani E., Chadwick E., Cincinelli A., Claßen D., Danielsson S., Dekker R., Duke G., Glowacka N., Jansman H., Krone O., Martellini T., Movalli P., Persson S., Roos A., O'Rourk E., Siebert U., Treu G., van den Brink N., Walker L., Slobodnik J., (Corresponding) Thomaidis N.

Topic:

Emerging pollutants

Per- and polyfluoroalkyl substances (PFAS) are a class of emerging substances that have proved to be persistent and highly bioaccumulative. They are widely used in industrial and consumer applications and are known for their long-distance migration and toxicity. In this study, 65 recent specimens...Read more

Assessing the performance of green nano Zero Valent Iron in column experiments for the removal of NSAIDs from water

(Corresponding) Panagou I., Kalli M., Noutsopoulos C., Mamais D., Koumaki E., Malamis S.

Topic:

Emerging pollutants

The existence of emerging contaminants in the aquatic environment is globally a major concern. Among them, non-steroidal anti-inflammatory drugs (NSAIDs) are a vast category of pharmaceuticals that are widely consumed and cannot be completely removed in typical wastewater treatment systems, thus...Read more

Detection of Aflatoxin M1 in milk using Mach-Zehnder optoelectronic immunosensors

(Corresponding) Angelopoulou M., Kourti D., Misiakos K., Economou A., Petrou P., Kakabakos S.

Topic:

Emerging pollutants

Aflatoxin M1 (AFM1) is excreted in milk of animals after ingestion of food contaminated with Aflatoxin B1 (AFB1). AFM1 has been considered as group I carcinogen since 2002, so the consumption of even low concentrations of AFM1 pose a major threat for human health. In this work, a silicon-based...Read more
