The effect of incorporating biosolids on soil quality after cotton crop management
(Corresponding) Giannakopoulos E., Makrygianni E., Evangelou E., Salachas G.
Topic:
New solutions for a better and sustainable agriculture
pilot sewage sludge (also known as “biosolids”, BS) application of 7,000 kg/ha (dry weight) was performed in the area of Lamia prefecture, central Greece, in two fields cultivated with Cotton. BS was very rich in organic matter (75%) and had high concentrations of nutrients, with all heavy metals...Read more

Can mixed oxides act as efficient photocatalysts for the elimination of organic water pollutants?
(Corresponding) Favier L., Sescu A., (Corresponding) HARJA M., Siamer S., Lutic D.
Topic:
Advanced oxidation processes
New mixed-metal oxides containing zinc and lanthanum were prepared by coprecipitation. The synthesized nanocomposites were calcined, and characterized by scanning electron microscopy (SEM), X-ray diffraction, FT-IR, BET and DR analysis. The calcined sample showed a higher crystalinity, confirmed by...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
Membrane Aerated Biofilm Reactor: A Correlation between Biofilm Thickness and Removal of Pharmaceuticals and Endocrinal Disruptor Compounds
(Corresponding) Sanchez-Huerta C., Fortunato L., Leiknes T., Hong P.
Topic:
Wastewater treatment
Removal of thirteen pharmaceuticals and endocrinal disruptor compounds via membrane aerated biofilm reactor was tested. MABR system demonstrated good management of nitrogenous nutrients. An increase in biofilm thickness enhanced the removal of analgesics, hormones, and disinfectants.
Low temperature conversion of methanol to higher hydrocarbons and hydrogen using a non-thermal plasma
(Corresponding) Dahiru U., Zhang K., Harvey A.
Topic:
Environmental odour, monitoring and control
In recent years, the emission of volatile organic compounds (VOCs) from chemical manufacturing plants, agricultural practises, and indoor sources has attracted public concern, as these emissions have a negative effect on both human health and the environment. VOCs are precursor for the formation of...Read more
Hydrogen and organic acids production from mesophilic and thermophilic dark fermentation of sugarcane vinasse without buffers
(Corresponding) Ribeiro J., Mota T., Oliveira V., Zaiat M.
Topic:
Wastewater treatment
The main objective of this study was to evaluate the valorization of vinasse dark fermentation (DF) through bioH2 and value-added metabolites production without buffers in two similar Upflow Anaerobic Sludge Blanket (UASB) reactors under mesophilic (U30) and thermophilic (U55) conditions. An...Read more

Quality evaluation of composts in the Greek market
(Corresponding) GYPARAKIS S., MARAGKAKI A., MANIOS T.
Topic:
Biowaste
In recent years, many composting products of various organic residues have been placed on the Greek market. Some of the benefits of composting, in addition to protecting the environment, are saving money, reducing wastes, improving soil quality and further complying with EU environmental rules...Read more
Sustainable treatment of air pollutants by moving bed biofilm reactor (MBBR) coupled with algae photobioreactor (APBR)
Pahunang R., (Corresponding) Zarra T., Oliva G., Senatore V., Belgiorno V., Ballesteros F., (Corresponding) Naddeo V.
Topic:
Environmental odour, monitoring and control
The presence of high concentrations of VOCs in the atmosphere can lead to negative consequences for humans and the environment. The treatment of these compounds is thus necessary before their release into the atmosphere. In the study, an advanced moving bed biofilm reactor (MBBR) coupled with an...Read more
Investigation of the presence of organic micropollutants in biota specimens from the Antarctica ecosystem using state-of-the-art wide-scope target and suspect HRMS methodologies.
Gkotsis G., Nika M., Vasilatos K., Orfanioti A., Athanasopoulou A., Alygizakis N., Oswald P., Slobodnik J., (Corresponding) Thomaidis N.
Topic:
Emerging pollutants
The contamination of the aquatic ecosystem with organic micropollutants due to anthropogenic activities, over the last decades, is a well-known issue. Due to the frequent detection of these chemicals in various environmental compartments, they are considered as potential threats to the aquatic...Read more

Development and validation of a novel analytical protocol for the simultaneous determination of organic micropollutants in biota specimens by GC-APCI-QToF MS.
Orfanioti A., Gkotsis G., Nika M., (Corresponding) Thomaidis N.
Topic:
Emerging pollutants
During the last decades, overwhelming evidence has shown that various xenobiotic compounds have been released into the environment, due to anthropogenic activities. The term “Persistent Organic Pollutants (POPs)” has been established for organic chemicals that are resistant to degradation,...Read more
