Natural presence of hexavalent chromium in spring waters of South-West Mountain Vermion, Greece
STAMOS A., SAMIOTIS G., PEKRIDIS G., TSIOPTSIAS C., (Corresponding) AMANATIDOU E.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
Hexavalent chromium in water occurs as oxoanions that are toxic for plants and animals. Furthermore, they are soluble and extremely mobile under environmental conditions. Chromium in its other common oxidative state (Cr+3) is less toxic and in general immobile. Chromium is found in nature mainly in...Read more
Origin of Cr in alluvial sediments and ultramafic rocks in Sultanate of Oman. Magnetic fractionation and sunlight effect.
(Corresponding) Moraetis D., Al-Suhai S., Pracejus B., Pyrgaki K., Argyraki A., Dermatas D.
Topic:
Soil and groundwater contamination and remediation
The present study attempts to identify the sources of Cr(VI) in a coastal alluvial fan soil and soil from a chromite mine. In addition investigates the effect of photochemically oxidized organic matter in the Cr(VI) mobilization in soil. The alluvial bulk soil samples contain several evidence of...Read more
Synthesis and characterization of nanomagnetite for environmental applications
(Corresponding) Mystrioti C., Papassiopi N., Xenidis A.
Topic:
Environmental applications of nanomaterials
Μagnetite (Fe3O4) in nanoscale has been very attractive due to its unique properties which make it ideal for a wide range of applications. Nanomagnetite can be applied as drug delivery medium, as catalyst and as efficient adsorbent and reducing agent for water treatment. In this study, magnetite...Read more

Catalytic reduction of Cr(VI) using recovered Silicon from end-of-life photovoltaic panels as a catalyst
Pavlopoulos C., Kyriakopoulou V., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
As installed photovoltaic panels (PVP) approach their end of life, the need for a sustainable recovery plan becomes imperative. This work aims to reuse Silicon from End-of-Life PVP as a potential catalyst/photocatalyst for wastewater treatment. PVPs were pretreated thermally (550°C for 30 min). The...Read more
In-situ bioremediation of groundwater polluted with Cr(VI) under anaerobic conditions
Galani A., Anastopoulou P., Noutsopoulos C., (Corresponding) Mamais D.
Topic:
Soil and groundwater contamination and remediation
The natural capacity of several microbes to reduce Cr(VI) to Cr(III) has been considered of much interest in order to remediate soil and groundwater polluted with Cr(VI). The objective of this work is to evaluate the enhancement of the activity of indigenous Cr(VI) reducing bacteria by the addition...Read more
Chromium VI bioremediation from Tannery Effluent and contaminated soil using Tamarindus indica leaves extract-immobilized nanoparticles
(Corresponding) Babangida S., Aliyu M., Abdullahi S.
Topic:
Heavy metals in the environment
The potential for application of bioreduction of Cr(VI) as an alternative to chemical remediation strategy has been highlighted in several works of literature. The objective of the study was to determine Cr(VI) reduction capacity of nanoparticles-encapsulated Tamarindus indica methanolic leaves...Read more

Year-round assessment of water pollutants in five Greek rivers
(Corresponding) Lymperopoulou T., Zarkaliou A., Papadopoulou K., Lyberatos G.
Topic:
River systems in diverse climates and environments
Globally, an estimated 80% of industrial and municipal wastewater is discharged into the environment without any prior treatment, with adverse effects on human health and the ecosystem. The current study was conducted for a year-round assessment of water pollutants in five Greek rivers (Glafkos,...Read more
