New pillared clays for the removal of pollutants from wastewater by treatment with oxidation processes
(Corresponding) Kalmakhanova M., Massalimova B., Diaz de Tuesta J., Gomes H.
Topic:
Advanced oxidation processes
The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents that makes necessary the development of new (and/or improvement of the existing) treatment methods and catalytic materials. In this sense, the use of...Read more
Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...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

The presence of organochlorinated pesticides in the marine environment of the Mediterranean Sea: A Systematic Review
TZOURTZOUKLI H., PETSAS A., (Corresponding) VAGI M.
Topic:
Marine environment and coastal management
Plant protection products, also known as pesticides, are chemical compounds that are used for the protcection of plants against pests, weeds and diseases which affect the quantinty and quality of agricultural products. The present study is a systematic review of the scientific literature regarding...Read more
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
