An innovative green iron-fertilizer, produced biotechnologically, for correcting iron chlorosis of soybean plants grown in calcareous soils
(Corresponding) Soares H.
Topic:
Environmental biotechnology and bioenergy
Iron deficiency is one of the main causes of chlorosis in plants, which leads to the loss in the field crops quality and yield. Iron-deficiency is a worldwide problem, particularly sever in calcareous soils (about 30% of world´s land surface).
The current use of synthetic iron-chelates to prevent...Read more

A practical time discretization methodology for adjusting the dosage profile in photo-Fenton processes
Xiangwei Y., Graells M., (Corresponding) Perez-Moya M.
Topic:
Advanced oxidation processes
Photo-Fenton processes are effective for mineralizaing aqueous solutions containing emergent pollutants. Accordingly, a number of works has been dedicated to determining conditions enhancing their performance (Pouran et al.,2015; Wang et al.,2016).
Despite improvements, solutions are still far...Read more
3D printed lab-scale raceway ponds reactors for photo-Fenton processes
Nasr Esfahani K., Zandi M., Travieso-Rodriguez J., Graells M., (Corresponding) Perez-Moya M.
Topic:
Advanced oxidation processes
Abstract
Raceway pond reactors (RPRs) have been widely used in microalgae mass culture (Acien et al., 2013) and their application for micro pollutant removal in photo-Fenton processes has been recently assessed (Rivas et al., 2015). The main advantages of raceway pond reactors are being low cost...Read more

Harmonization of sampling and chemical analysis for the study of Cr(VI) water contamination in aquifers of eastern Mediterranean and Oman: the CrITERIA project experience
(Corresponding) Argyraki A., Kelepertzis E., Pyrgaki K., Botsou F., Megremi I., Dermatas D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
The CrITERIA project aims to deliver a harmonized data base, to assist water resource management organizations and water users on decision making when coping with water scarcity, climate extreme events and contaminated water. Contamination by Cr(VI) is used as an example of a specific water...Read more

Evaluation of a new millifluidic device for the consistent determination of oil droplet biodegradation kinetics
(Corresponding) Kapellos G., Nagarajan M., Kalogerakis N., Doyle P.
Topic:
Process understanding through innovative sensors and remote sensing
Natural seeps and accidental releases of crude oil in the sea result in swarms of droplets that are carried away by underwater sea currents. The droplets may be created either at the sea surface during the breakup of an oil slick by sea waves, or at the seafloor during the extrusion of crude oil...Read more
The influence of graphene addition on the properties of composite membranes RG / PAN and their potential application
(Corresponding) Fryczkowska B.
Topic:
Nanomaterials in the environmnents applications and effects
PAN is an inexpensive and popular engineering polymer, which is widely used in membrane techniques: ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and pervaporation (PV). It is characterized by good thermal stability, high thermal conductivity, chemical resistance, solubility in...Read more
Interactions between rhizosphere microorganims and spontaneous plant species inhabiting smelter wastelands
(Corresponding) Siebielec S., Siebielec G., Sugier P., Stuczynski T.
Topic:
Soil and groundwater contamination and remediation
Processes of spontaneous vegetation of toxic smelter waste deposits are slow. However permanent plant cover, effectively limiting dispersion of metals, should be based both on introduced grasses and spontaneous species to ensure greater plant diversity and resistance of such ecosystem. The role of...Read more
Co-creating data based on human nose perceptions to study odour nuisance from an oilseed industry
(Corresponding) Teixeira S., Pereira P., Ferreira F.
Topic:
Environmental odour, monitoring and control
Odour nuisance is the second environmental problem with more citizen complaints after noise. This fact and the lack of odour regulation in Portugal led way to develop a bottom-up approach focused on citizens to co-create the analysis. Despite the existence of odour measuring instruments, the human...Read more
New evidence of accelerated elimination of an emergent water pollutant by TiO2 assisted photo-oxidation
(Corresponding) FAVIER L., LASLAU A., SIMION A., SESCU A., HARJA M., RUSU L.
Topic:
Advanced oxidation processes
Over the past few years, the presence of the pharmaceuticals and their metabolites in the aquatic environment has become an important public health issue. These molecules are generally released in the aquatic ecosystem through the effluents of conventional wastewater treatment plants which were not...Read more

Durability of cement mortars and concretes exposed to biological attack as one of the sustainability parameter – a correlation analysis
(Corresponding) Ondrejka Harbulakova V., Estokova A., Smolakova M., Luptakova A.
Topic:
Energy technologies and sustainability
Among the pillars of the sustainability, the aspect of prolongation of life of constructions has to be involved. Focus on sustainability of construction leads to study of durability of building materials. Phenomenon called biocorrosion, existing mainly in concrete sewer systems, agricultural...Read more
