The sorption coefficient, K(OC), of phenanthrene (PHE) has been reported to vary with different types of organic matter, leading to uncertainties in predicting the environmental behavior of PHE. Among the studies that relate organic matter properties to their sorption characteristics, physical conformation of organic matter is often neglected. In this work, organic matter samples of different p...

Using a wide range of modern mineralogical and physicochemical methods, representative collection human bones from seven burial grounds the Vychegda Permians 11th–14th centuries was studied. The microstructure bones, their chemical normative-mineral composition, content microelements, nanoporosity organo-mineral composite, composition properties bioanatite bone collagen were analyzed. Fundament...

Both microbially produced enzymes and mineral surfaces can be considered catalysts of chemical transformation in soils and other geological environments such as sediments and subsurface aquifers. While both are important direct agents of organic matter (OM) remineralization and transformation, mineral surfaces can also act as “heterogeneous co-catalysts,” influencing the kinetic properties of b...

The aim of this study was to produce mulch by combining natural mineral and organic substances in order to reach soil stabilization and improve soil physical and mechanical properties in Koopal area. The effects of organic mulch (at 3 levels of O1: combination of 1% sugarcane bagasse biochar+0.5% gum Arabic+0.5% gelatin; O2: combination of 3% sugarcane bagasse biochar+1% gum Arabic+1% gelatin; ...

The elemental composition and structure of humic acids in the soddy-podzolic heavy loamy soil Cis-Urals were studied during long-term application organic, mineral organo-mineral fertilizers under conditions a stationary experiment. Mineral contributed to formation with increased content aliphatic components, ratio H : C = 1.45 high degree oxidation (ω 0.41). low nitrogen (from 2.0 2.6 at.%), va...
