Synthesis of Fe3O4/Carbon Quantum Dots Hybrid for Efficient Removal of Congo Red Dye from Aqueous Solution
(Corresponding) Zourou A., Axarli V., Falara P., Ntziouni A., Kordatos K.
Topic:
Water treatment
During the past decades, the release of toxic pollutants into aquatic environment has continuously increased due to rapid industrialization and civilization. The presence of organic dyes, such as Congo Red (CR), can be dangerous to both human and aquatic life. Therefore, their removal is an...Read more

Citizens' awareness and education for tackling microplastic contamination in freshwater ecosystems
(Corresponding) Rodrigues C., Ribeiro A., Silva N., Silva A., Gravato C., Ribeiro C.
Topic:
Case studies of macro- and microplastics pollution in coastal waters and rivers
Microplastics (MPs) are ubiquitous and persistent contaminants, particularly in river sediments reaching high abundances with potential to impair ecosystem functions and services of great importance to humankind. Thus, monitoring programmes and public awareness are pivotal to implement mitigation...Read more
Pedestrian preferences of urban design features in city squares of Athens, Greece
(Corresponding) Pantavou K., Koletsis I., Lykoudis S., Tsiros I.
Topic:
Environmental data analysis and modelling
Public open spaces improve the quality of life in cities and form places for community gatherings and outdoor activities. This study examines the preference of pedestrians for the design features of urban squares. Field surveys on the perception of environmental stimuli were conducted in five...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
Hydrogen production in a microbial electrolysis cell: the influence of operational parameters
(Corresponding) ANTONOPOULOU G., APOSTOLOPOULOS I., BAMPOS G., BEBELIS S., LYBERATOS G.
Topic:
Environmental biotechnology and bioenergy
In the present study two identical two-chamber microbial electrolysis cells (MECs), fed with an acetate synthetic medium, were used for hydrogen production, using different anodic materials, i.e. commercial carbon fiber paper (CP) and graphite granules (GG). The effects of the applied voltage (i.e...Read more
Quantitative target screening and soil bioavailability assessment as tools to assess risks associated with wastewater reuse for irrigation
Beretsou V., Nika M., Manoli K., Lundy L., Thomaidis N., Revitt M., (Corresponding) Fatta-Kassinos D.
Topic:
Emerging pollutants
Multi-residue analysis of various classes of contaminants of emerging concern (CECs) present in wastewater, along with improvements in analytical methodologies, may allow for future application of promising wastewater tracers, thus providing wastewater treatment plant (WWTP) operators and...Read more
Keywords:
contaminants of emerging concern, metabolites, transformation products, high-resolution mass spectrometry, risk assessment, wastewater reuse
Photoluminescence spectroscopy on commercially available plastic products
(Corresponding) Konde S., Brackmann S., Hüppe F., Koch M.
Topic:
Case studies of macro- and microplastics pollution in coastal waters and rivers
Commercially available plastic products are produced for specific applications. They represent polymeric compounds, i.e. base materials mixed with various types of additives such as pigments. The identification of the plastic type is the key goal in microplastics analysis but also the key process...Read more
Validation of ENVI-met microscale model with in-situ measurements in warm thermal conditions across Athens area
Koletsis I., Tseliou A., Lykoudis S., Tsiros I., Lagouvardos K., Psiloglou B., Founda D., (Corresponding) Pantavou K.
Topic:
Environmental data analysis and modelling
Validation is critical for quantifying accuracy, errors and limitations of models’ results. This study examines the ability of ENVI-met model to simulate thermal conditions in high spatial resolution. Field measurements from 11 central sites (squares and parks) across the greater area of Athens,...Read more

Can the seasonal variability affect the BMP of fruit and vegetable waste?
(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic:
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...Read more
