In classical aquaponics (coupled aquaponic systems, 1-loop systems) the production of fish in recirculating aquaculture systems (RAS) and plants in hydroponics are combined in a single loop, entailing systemic compromises on the optimal production parameters (e.g. pH). Recently presented decoupled aquaponics (2-loop systems) have been awarded for eliminating major bottlenecks. In a pilot study,...

UraniumIV sulfate in an aqueous solution and the solid state has been investigated with extended X-ray absorption fine structure (EXAFS) and X-ray diffraction (XRD). The coordination polyhedron comprises monodentate sulfate, bidentate sulfate, and water molecules. The coordination modes of sulfate in solution have been determined from the U-S distances with EXAFS. The U-S distance of 3.67 +/- 0...

Abstract. Seasonal to interannual variations in the concentrations of sulfur aerosols (< 2.5 µm diameter; non sea-salt sulfate: NSS-SO42-; anthropogenic Anth-SO42-; biogenic Bio-SO42-; methanesulfonic acid: MSA) Arctic atmosphere were investigated using measurements chemical composition collected at Ny-Ålesund, Svalbard (78.9? N, 11.9? E) from 2015 2019. In all measurement years concentratio...

Anthropogenic activities such as industry, agriculture, and daily life are related to metal pollution of the environment. Places known of the highest impact are fishponds where intensive fish farming is believed to input a significant amount of various elements to water. Additionally, many studies suspect wetland hunting activity of water lead pollution. The present paper aims to check if hunti...

The Bundelkhand region of Central India has been facing increasing severity droughts, water-level depletion and deterioration in water quality. In this perspective, an attempt made for a qualitative evaluation surface groundwater resources belonging to the rural environment understand contaminant’s source probable human health risk due intake available water. samples collected from were analyse...

Ramanathapuram is a drought-prone southern Indian district that was selected for conducting hydrogeochemical study. Groundwater samples from 40 locations were collected during January 2020 (pandemic interdiction according to COVID) and 2021. The properties of the groundwater evaluated compared with drinking water regulations assess their quality. order cation dominance as follows: Na+ > Ca2+...

This study focusses on the evaluation of Euphrates River in Al-Anbar Governorate, through monthly collection water samples for a full year from twelve stations extending Al-Qaiem to Ameria. Because is source residents surrounding areas, therefore, continuous during close periods necessary. Accordingly, 144 were analyzed and their chemical physical properties determined. The results showed that ...

Sulfated titania nanoparticles (SO42-/TiO2 NPs) were synthesized using titanium tetraisopropoxide (TTIP) by the sol-gel method. The structure and morphology of the prepared nanocatalyst was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET) methods as well as Fourier transform infrared (FT-IR) and energy dispersive X-ray (EDX) spectr...
