The article presents the research results dealing with influence of such natural minerals as flint and shungite in relation to following water parameters pH, TDS, conductivity, cations (NH4+, K+, Na+, Mg2+, Sr2+, Ba2+, Ca2+) anions (Cl−, SO42−, NO3−, F−, СО32−). It was found that crushed added more significantly increases hydrogen index if compared sedimentation. Simultaneously total mineraliza...

The physical state of the tropospheric aerosol is largely unknown despite its importance for cloud formation and for the aerosol’s radiative properties. Here we use detailed microphysical laboratory measurements to perform a systematic global modelling study of the physical state of the H2SO4/NH3/H2O aerosol, which constitutes an important class of aerosols in the free troposphere. The Aerosol ...

The synthesis and crystal structures of three heteroleptic complexes Zn(II) Cd(II) with pyridine ligands (ethyl nicotinate (EtNic), N,N-diethylnicotinamide (DiEtNA), 2-amino-5-picoline (2Ampic) are presented. complex [Zn(EtNic)2Cl2] (1) showed a distorted tetrahedral coordination geometry two EtNic ligand units chloride ions as monodentate ligands. Complexes [Zn(DiEtNA)(H2O)4(SO4)]·H2O (2) [Cd(...

The mineral surface structure and ions’ interaction were of significant interest to understanding dissolution reaction. In this study, X-ray photoemission spectroscopy combined with ICP emission spectrometer was used investigate the influence leaching reaction conditions 8 M dilute sulfuric acid 12 concentrated on chemical composition, (valence) state ion distribution Columbite-(Fe) (FeNb2O6). ...

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...

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,...
