Cobalt- and copper-modified coal fly ash nanozeolites for environmental protection applications
(Corresponding) Boycheva S., Marinov I., Lazarova H., Zgureva D., Václavíková M., Popova M.
Topic:
Nanomaterials in the environmnents applications and effects
Fly ash zeolites (FAZ) are promising materials for adsorbents, ion-exchangers and catalysts. FAZ usually possess a mixed micro-mesoporous structure that facilitates mass transport phenomena through their framework. Due to the transfer of iron spinel oxides and many metal species from the raw...Read more
Statistical modeling of meteorological conditions and air pollution over Athens, Greece
(Corresponding) DELIGIORGI D., PHILIPPOPOULOS K., DIAMANTI A.
Topic:
Air pollution
The importance of meteorological parameters and topography in determining the air pollution levels in a specific area is well established. The aim of this study is to model the association between air pollution levels and meteorological parameters for a single site in Athens, Greece. The...Read more

A DPSIR approach to selected Cr(VI) impacted groundwater bodies within Attica and Eastern Sterea Ellada River Basin Districts
(Corresponding) Pyrgaki K., Argyraki A., Kelepertzis E., Botsou F., Megremi I., Karavoltsos S., Mpouras A., Dassenakis M., Hatzaki M., Dermatas D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) analytical framework in combination with Geographical Information Systems was applied to selected Cr(VI) impacted groundwater bodies. For the characterization of “state”, 157 samples including field blanks were collected...Read more
Influence of Varying Concentration of Toluene in a Soil Biofilter with Water Content Control
Badilla D.
Topic:
Air pollution
Contaminant concentration affects rate of removal of air contaminant in biofiltration. In this study, extent of degradation rate at varying concentrations of toluene (from 50 to 700 ppm) as the air contaminant in terms of elimination capacity (EC) was measured in a soil biofilter with water content...Read more

Long-term impact of use of treated wastewater on accumulation of metals in soil.
(Corresponding) Elsergany M., KARKAIN R., DIAMADAPOULOS E., Moussa M.
Topic:
Water and wastewater reuse
The aim of this paper is to assess the environmental risks associated with the wastewater reuse with respect to six metals; cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) in the city of Dubai. Treated Sewage Effluent (TSE) is used for landscape irrigation. Samples of...Read more

Dioxin-Like Polychlorinated Biphenyls at Dilijan Landfills (Republic of Armenia)
(Corresponding) Aleksandryan A., KHACHATRYAN A., Bunyatyan Y.
Topic:
Emerging pollutants
Polychlorinated biphenyls (PCBs) are substances of wide distribution, high toxicity, persistence, and ability to long-distance migration. They are characterized by unique properties: temperature stability; high boiling point; non-combustibility; resistance to chemical and physical influences; high...Read more
Isolation and identification of microorganisms that can biodegrade organic compounds which are present in olive mill waste.
(Corresponding) Antwnopoulou P., Vyrides I., Stasinakis A.
Topic:
Wastewater treatment
Isolation of microorganisms that can biodegrade organic compounds which are present in olive mill waste and more specifically microorganisms that can survive at high phenol concentrations was studied in the Environmental Engineering Laboratory for three months in the Department of Environmental...Read more
The possibility of recycling of multilayer packaging waste: Reducing Environmental impacts
(Corresponding) Mumladze T., ŠLEINIŪTĖ A., Denafas G.
Topic:
Solid waste management
Multilayer Packaging Waste (MPW) represents the largest fraction of packaging waste and is mainly composed of multiple plastic films laminated with Al foil. Most produced multilayer film is based on the different polymers, such as: polyester (PET), polypropylene (PP), and polyethylene (PE) as main...Read more
The comparison of sediment quality in the rivers the Eastern Slovakia by Potential ecological risk index
(Corresponding) Singovszka E., Balintova M.
Topic:
Heavy metals in the environment
The current pollution of sedimentary environment is very serious and exceeds load capacity limit and it is influenced by other external factors such as climate, hydrodynamic conditions, pH, salinity, Eh, temperature and other. This influences can cause the heavy metals are re-released from the...Read more
