Analysis of hydrochemical time series

(Corresponding) Kolarec B., Žeravica A.

Topic:

Soil and groundwater contamination and remediation

Agricultural activity of spreading fertilizers may, in case they are washed away to an aquifer, result in a groundwater contamination. There was a research conducted in Croatia on the lower part of the Danube-Sava canal which is occupied by extensive agricultural production to measure the...Read more

Identification and Quantification of Microplastic in Sewage systems by TED-GC-MS

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

Topic:

Microplastics in the marine environment

Over the last years, the number of publications reporting the amount of microplastic (MP) all over the world increased rapidly. But harmonised sampling, sample preparation and analysis strategies are missing. Commonly used methods are very time consuming and not comparable to each other. Hence,...Read more

Multivariate Analysis of Large µ-FTIR Data Sets in Search of Microplastics

(Corresponding) Wander L., Vianello A., Vollertsen J., Braun U., Paul A.

Topic:

Microplastics in the marine environment

µ-FTIR spectroscopy is a widely used technique in microplastics research. It allows to simultaneously characterize the material of the small particles, fibers or fragments, and to specify their size distribution and shape. Modern detectors offer the possibility to perform two-dimensional imaging of...Read more

Assessment of water quality of Asopos River in central Greece using multivariate analysis

Tsadilas C., Tzouvalekas M., (Corresponding) Evangelou E., Papadopoulos S., Papadoulis A., Petsoulas C., Tsitouras A., Grypari P., Smyrnis T.

Topic:

Lakes, rivers, estuaries and ecosystem health

The main objective of this study was to assess the quality of water from five monitoring stations in Asopos River (central Greece), and evaluate the main factors that affect the river water quality. Fifty one biochemical parameters measured both in situ and in the laboratory three times a year for...Read more

Evaluating production and utilisation pathways of a coupled Anaerobic Digestion (AD) and Gasification/Pyrolysis system using Life Cycle Analysis (LCA).

(Corresponding) Curry R., Cromie T., Somerville G.

Topic:

Life cycle analysis (lca)

Life Cycle Analysis modelling has been applied to an operational Anaerobic Digestion (AD) plant, (utilising Cattle Slurry/Grass Silage), currently producing biogas for electricity and heat production, with digestate going to land-spreading. The aim of the research was to evaluate the environmental...Read more

(Corresponding) López-Serna R., García D., Bolado S., Jiménez J., Lai F., Golovko O., Ahrens L., Wiberg K., Gago-Ferrero P., Muñoz R.

Topic:

Emerging pollutants

This work identified transformation products (TPs) from 5 antibiotics and 1 analgesic, namely enrofloxacin, marbofloxacin, danofloxacin, amoxicillin, penicillin G and dexamethasone, respectively, present in spiked real piggery wastewater (PWW) before and after two different treatments in two open...Read more

Life cycle assessment of the use of biomass as energy source in Northern Greece

Dounavis A., Karamanos L., Lekkas D., (Corresponding) Klontza E.

Topic:

Life cycle analysis (lca)

Decrease of fossil fuel consumption in the energy sector is an important step towards more sustainable energy production.
