Sampling Strategies of Microplastic in Stormwater Runoff from Separate Drainage Systems

(Corresponding) Abusafia A., Scheid C., Meurer M., Altmann K., Braun U., Bannick C., Dittmer U., Steinmetz H.

Topic:

Emerging pollutants

The occurrence of microplastic in terrestrial and water environments can be traced back to anthropogenic activities. Urban drainage systems play a role in transporting microplastic from urban sources into receiving waters or soils. The analysis (including sampling, sample preparation and detection...Read more

Biodiesel Properties from Chlorella sorokiniana Bio-Oil Cultivated Heterotrophically with Industrial By-Products

Kokkalis A., Kasiteropoulou D., Papadopoulou A., Metsoviti M., Mpesios A., Gougoulias N., Spiliotis X., (Corresponding) Papapolymerou G.

Topic:

Environmental biotechnology and bioenergy

The fatty acid (FA) distribution of bio-oil derived from Chlorella sorokiniana and the biodiesel basic properties were examined. C. sorokiniana was cultivated heterotrophically in two growth media: a) glycerol and inorganic salts (GLIN) and b) glycerol and anaerobic digestrate (GLAD). The...Read more

AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc

Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.

Topic:

Wastewater treatment

A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...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

Quantifying and mapping urban trees' decay severity using thermal and spatial indices: implications for tree hazard assessment and management

(Corresponding) Zevgolis Y., Troumbis A.

Topic:

Disaster risk reduction and management

Wood decay, a crucial factor in tree stability, is an internal long-term interaction between fungi and tree that leads to the disruption of energy flow, temperature abnormalities on the tree's surface, and possible tree mortality, especially when the decay extent is close to the threshold of...Read more

Non-destructive diagnostics for estimating fungal infection in resin-tapped and non-tapped pine trees

(Corresponding) Zevgolis Y., Zannetos S., Sazeides C., Fyllas N., Troumbis A.

Topic:

Biodibersity conservation

In pine stands systematic harvesting of forest products, such as resin extraction, are known to affect trees’ vitality and consequently their response to fungal diseases. The latter constitutes a serious threat for standing vigorous trees, thus early warning signals and short diagnosis time of...Read more

Support Structure Suitability for Offshore Wind Farms Development in Greece based on a Sustainable Site-Selection Framework

(Corresponding) Spyridonidou S., Vagiona D.

Topic:

Energy technologies and sustainability

Site-selection and spatial planning form a crucial step toward the successful development of Offshore Wind Farms (OWFs). Deployment of wind turbines in different water depths has raised the issue of selection of the most suitable support structures. In this work, a well-structured site-selection...Read more

Monitoring illicit stimulant drug use in Cyprus during the COVID-19 lockdown by UPLC-MS/MS

Psichoudaki M., Trapali A., Hapeshi E., Karaolia P., Savvidou M., Mina C., Michael C., (Corresponding) Fatta-Kassinos D.

Topic:

Wastewater-based epidemiology to monitor covid-19 outbreak: present and future diagnostic methods to be in your radar

The occurrence and spread of the novel corona virus SARS-CoV-2 at the end of 2019, has led WHO to announce the outbreak of a pandemic. Restriction measures were taken from authorities globally, in order to impede its spread. In Cyprus, a strict lockdown period was implemented on the 24th March of...Read more

"Plastisphere - the holistic approach and numerical description of microplastics surfaces"

(Corresponding) Dąbrowska A.

Topic:

Case studies of macro- and microplastics pollution in coastal waters and rivers

The aim of this research is to discuss the current state-of-art, basic data and the methodology for the quantitative and qualitative physical and chemical characterisation of the marine microplastics (MMs; polymer debris < 5 mm) and the Plastisphere. In particular, the surface of synthetic...Read more

Topic:

Solid waste management

This work presents the development of magnetic carbon nanotubes (MCNTs) from plastic solid waste (PSW). For this purpose, diverse catalytic nanoparticles based on Fe, Ni and Al were prepared by impregnation of alumina or co-precipitation of Ni, Fe and Al nitrate salts with NH4OH, followed by...Read more
