Photocatalytic elimination of water pollutants using innovative titania thin film heterostructures embedding carbon quantum dots
(Corresponding) Falara P., Zourou A., Ibrahim I., (Corresponding) Kordatos K.
Topic:
Water treatment
Titanium dioxide based photocatalysis is a well-established advanced oxidation process (AOP) that recently has expanded its borders comprising advanced reduction processes (ARPs) as well. To enhance the photocatalytic activity, titania heterostructures embedding semiconductors, or clays, or...Read more
Smart Technologies for the Control of Emerging Contaminants in Ambient Air
(Corresponding) Galang M., Zarra T., Belgiorno V., Naddeo V.
Topic:
Emerging pollutants
Air quality protection and control is an issue of growing interest. The aspects related to the spread of the coronavirus have accentuated this attention. Furthermore, among the emerging contaminants (EC’s) in ambient air, the microplastics (1 – 5 μm) are a great concern arising from anthropogenic...Read more

Interactions between microplastics and organic pollutants: Effects on transport and bioaccumulation: from the lab to the environment
(Corresponding) Picó Y., Campo J., Alfarhan A., El-Sheikh M., Barceló D.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
Microplastics (MPs) have the ability to extract/preconcentrate other contaminants from water samples and could also act as vectors to other environmental compartments. The occurrence and distribution of MPs in different points of Al-Jubail, the most important industrial city, and the second biggest...Read more

Solar photocatalytic degradation of pharmaceutical compounds using ZnSnO3/CB composites
Kouvelis k., Petala A., (Corresponding) Frontistis Z., Kondarides D.
Topic:
Advanced oxidation processes
In this study, the activity of ZnSnO3 as a photocatalyst for the degradation of persistent micro–pollutants under simulated solar irradiation has been assessed. Zinc stannate (ZnSnO3), belongs to the class of ternary oxides and has a reported band gap of 2.4 eV. Due to its narrow band gap can be...Read more
EVALUATION OF THE EFFECTS OF THE COVID-19 RESTRICTIONS MEASURES ON THE AIR QUALITY AS A TOOL TO IMPLEMENT PREVENTION STRATEGIES
Oliva G., (Corresponding) Zarra T., Senatore V., Giaquinto D., Galang M., Belgiorno V., Naddeo V.
Topic:
Air pollution
The World Health Organization (WHO) at the end of January 2020 declared a Public Health Emergency of International Concern (PHEIC). At the end of March 2020, the epidemic turned into the pandemic. The consequent stringent lockdown measures adopted to mitigate the spread of the virus generated huge...Read more

Design of Road-Side Barriers to Mitigate Air Pollution near Roads
(Corresponding) Huertas J., Aguirre J., Lopez O., Lopez C.
Topic:
Air pollution
The effects of using solid barriers on the dispersion of air pollutants emitted from the traffic of vehicles on roads located over flat areas were quantified, aiming to identify the geometry that maximizes the mitigation effect of air pollution near the road at the lowest barrier cost. Toward that...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

Multi-scale high-resolution atmospheric emission inventory for the transport sector
(Corresponding) Lopes D., Augusto B., Rafael S., Graça D., Rosa M., Relvas H., Ferreira J., Reis J., Lopes M.
Topic:
Air pollution
This study aims to develop a multi-scale atmospheric emission inventory for the transport sector with high spatial and temporal resolution using Portugal as a case study. For that, a combination of the traditional method of emissions calculation with an innovative way to gather and process data (...Read more

Pilot scale investigation of an advanced photo-electro-chemical oxidation process for treatment of effluents from pesticides manufacturing plants
(Corresponding) Sarasidis V., Petsi P., Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
This paper reports on the effectiveness of an innovative hybrid advanced oxidation process-scheme aiming to degrade recalcitrant organic compounds in industrial effluents. Following targeted experimental work, a pilot unit was developed/built combining two advanced oxidation processes, based on in-...Read more
Cometabolic removal of ibuprofen, diclofenac and ciprofloxacin driven by glycerol fermentation in an acidogenic biofilm reactor
(Corresponding) Carneiro R., Gomes G., Zaiat M., Santos-Neto Á.
Topic:
Emerging pollutants
The presence of pharmaceuticals in wastewater has increasingly become a public health issue globally due to the potential impacts it can cause on the environment and public health. In this study, we sought to analyze the cometabolic effect of glycerol fermentation on the removal of ibuprofen (IBU...Read more
