Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae
Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.
Topic:
Environmental biotechnology and bioenergy
Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Hydro-stratigraphy, Aquifer Characterization and Physiochemical Analysis of District Dera Ghazi Khan Punjab, Pakistan.
(Corresponding) Ullah H., Khalid P., Shah G., Mashwani S., Shafiq W., Din Z.
Topic:
Water treatment
The study area is located in the arid section of Punjab province, Pakistan. The accessibility of freshwater is the main problem in this zone. The area is approximately flat and there are alluvial deposits up to 800 m. Groundwater is not fit for health because of its salinity. Hence, it is essential...Read more

Heavy metals in soil, sediments, and water from Lake Ohrid catchment (Albania)
(Corresponding) Bani A., Shallari S., Duka I.
Topic:
Heavy metals in the environment
Lake Ohrid is located in the Balkan Peninsula in South East Europe and it is shared between Albania and Macedonia. Formed in the tertiary period between 3.5 and 4 million years ago, Lake Ohrid is considered as one of the oldest lakes in the world, with numerous freshwater native and endemic...Read more

Bioleaching of valuable elements from red mud using autochthonous biomass
(Corresponding) Cozzolino A., Cappai G., Cara S., Milia S., Carucci A.
Topic:
Circular economy and industrial symbiosis
Red mud (RM) is the main residue produced by the alkaline extraction of aluminum from bauxite, and it contains valuable metals (e.g., iron, aluminum, titanium, silicon). Aim of this research was to investigate the biologically induced leaching of valuable elements from RM using autochthonous...Read more

Artificial Neural Network (ANNs) for predicting petroleum hydrocarbons from heavy metals contaminated soils around fuel stations
(Corresponding) Bonelli M., Manni A., Saviano G.
Topic:
Environmental data analysis and modelling
Petrol stations are classified as a dangerous source of pollution for the human population due to the toxicity of emissions from evaporated vehicle fuels and fuel spillages. The contaminants released in the environment are mainly complex mixtures of petroleum hydrocarbon compounds (PHCs) and heavy...Read more

The effect of incorporating biosolids on soil quality after cotton crop management
(Corresponding) Giannakopoulos E., Makrygianni E., Evangelou E., Salachas G.
Topic:
New solutions for a better and sustainable agriculture
pilot sewage sludge (also known as “biosolids”, BS) application of 7,000 kg/ha (dry weight) was performed in the area of Lamia prefecture, central Greece, in two fields cultivated with Cotton. BS was very rich in organic matter (75%) and had high concentrations of nutrients, with all heavy metals...Read more

On the geochemistry of Gialova lagoon, SW Peloponnesus, Greece
Papakonstantinou M., Sergiou S., Dimas X., Fakiris E., Christodoulou D., Geraga M., (Corresponding) Papatheodorou G.
Topic:
Heavy metals in the environment
The spatial distribution of lithological characteristics, organic carbon and major / trace elements was studied in the surface sediments of the Gialova lagoon, a shallow water lagoon (<1.0 m) which is located at southwestern Peloponnesus (Greece). The sediment samples were collected on the basis...Read more
AliCy as Extractant to Remove Iron from Copper-Free Extreme AMD for Further Extraction of Zinc
Nobahar A., Melka A., Neves L., Carlier J., (Corresponding) Costa M.
Topic:
Wastewater treatment
A previous work showed that copper can be specifically extracted from acid mine drainage (AMD) classified as high-acid and extreme-metals (pH 1.19, ~63 g/L Fe, ~6.5 g/L Al, ~5.3 g/L Cu, ~1.9 g/L Zn and ~0.1 g/L Mn), using 30% (v/v) Acorga M5640 in Shell GTL (a kerosene like solvent) as extractant...Read more
