Research on the ability of urban trees to retain heavy metals. A silvicultural approach.
(Corresponding) Vordoglou M., Samara T., Tsitsoni T.
Topic:
Heavy metals in the environment
The purpose of the present research was to study the ability of urban trees’ leaves to retain heavy metals. Three major heavy traffic streets of Thessaloniki were chosen. Two tree species were studied: Ailanthus altissima (Mill.) Swingle and Catalpa bignonioides Walt. and 360 leaf samples were...Read more

The aim of this paper is to analyse time series that might have an impact on prices of energy commodities. Analysis and econometric modelling reveal which time series are corelated and how. This is input for further modelling of forecasting tool for electricity and gas prices (in near future)...Read more
An initial study of the opinions of car purchasers in Poland: do they choose electric vehicles?
(Corresponding) Bienias K., Kowalska- Pyzalska A., Ramsey D.
Topic:
Urban environment and health
Road transport causes one fifth of the EU's total emissions of carbon dioxide (CO2), which are especially high in cities. A suggested solution to this situation is the introduction of electric vehicles (EV). However, evidence from European countries shows that, the sales of EVs are low in...Read more

Cavitation based Advanced Oxidation Processes for Wastewater Treatment – comparison of hydrodynamic and sonocavitation systems
(Corresponding) Boczkaj G., Gągol M., Fedorov K., Cako E.
Topic:
Advanced oxidation processes
Cavitation based advanced oxidation processes (AOPs), are a promising alternative to currently used wastewater treatment technologies [1-2]. Amplified interest in this “hot” topic results in increased number of research on several aspects relating to formation of cavitation phenomena and its...Read more
A simple and flexible flowsheet process for recycling efficiently and selectively metals from spent fluid cracking catalysts
(Corresponding) Soares H., (Corresponding) Sadeghi M., (Corresponding) Jesus J., (Corresponding) Pinto E., (Corresponding) Almeida A.
Topic:
Solid waste management
Fluid cracking catalysts (FCCs) are used in the oil industry to crack large molecules into smaller hydrocarbons of interest, such as gasoline and other products. Considering the large volume of FCCs waste generated on a yearly basis (about 20 thousand tons of spent FCCs worldwide) as well as its...Read more

Groundwater quality and hydrogeochemical characterization of Khetri copper mining region, India
(Corresponding) Punia A., Siddaiah N., (Corresponding) Bharti R.
Topic:
Soil and groundwater contamination and remediation
The impact of copper mine on groundwater quality in the semi-arid region is evaluated, and also characterized for hydrogeochemical processes. Groundwater samples (post monsoon and pre monsoon) from Khetri copper mine region of Rajasthan, India were studied. In majority of groundwater samples, the...Read more
Interactions between Plants and Rare Earth Oxide Nanoparticles
(Corresponding) Zhang Z.
Topic:
Nanomaterials in the environmnents applications and effects
Rare earth oxide nanoparticles (REO NPs) can be released into the environment from various application routes, but their effects on the ecosystem are still little known. In this study, we exposed cucumber seedlings to suspensions of La2O3 and CeO2 NPs for 14 d. Phytotoxicity of the two REO NPs was...Read more
This paper studies the dynamics of an economy specialized in fisheries facing a rising marine litter problem. We present a dynamic optimization model to explain the mechanism through which marine litter causes inefficiencies in the fishery sector. We study the dynamic properties of the model when...Read more
New generation of patterned membranes for water treatment
Asad A., Sameoto D., (Corresponding) Sadrzadeh M.
Topic:
Water treatment
Membrane technology is an energy-efficient separation process that is expected to dominate the water treatment industry. However, the high vulnerability of membranes to fouling has limited the expansion of sustainable and energy-efficient membrane processes. Surface patterning has been proven to be...Read more
Evaluation of risk and the beneficial effects of synthesized nano silver-based disinfectant on poultry mortality and health
(Corresponding) Kumar I., Bhattacharya J.
Topic:
Nanomaterials in the environmnents applications and effects
This study was evaluated for the potential use of nanosilver (nAg) as a disinfectant and antimicrobial growth promoter supplement for the poultry. The experiments were conducted in the Kangsabati river basin region, in West Medinipur district, West Bengal, India for six months. Two poultry farms...Read more
