“…A number of restoring technologies including biological and physico-chemical processes are available to reduce petroleum hydrocarbon concentrations in the environment (Sannino and Piccolo, 2013). Significant attention has been given to bioremediation, that mainly relies on the use of organisms with specific metabolic abilities in order to remove or minimize the toxic effect of organic and inorganic pollutants (de Almeida et al, 2017).…”

“…The amphiphilic nature of humic acids determines the formation of micelle-like structures. This property of HAs in neutral and acidic conditions determines the protective properties of soil organic matter, binding pollutants and preventing their entry into adjacent environments (Sannino and Piccolo, 2013). The composition of soil organic matter and its properties cause intense interest of scientists (Sbih et al, 2012;Hristov and Filcheva, 2017;Shahin and Khater, 2020).…”

The organic matter of the soil and humus are heterogeneous in composition. That is why the nature of soil organic matter has not yet been fully understood and causes many discussions. The purpose of this work is to study the identification features of humus in the process of peat's transformation. The results of a fiveyear experiment studying the processes of organic matter transformation in organic-mineral substrate based on peat growing coniferous seedlings in greenhouses are presented. In the dynamics of the group and fractional composition of humus for several years the biochemical essence of the humification process is revealed. To extract specific humic substances from the organogenic substrate, we used the method of fractioning humus into groups and fractions, which is a stepwise sequential extraction using solutions of sodium hydroxide and sulfuric acid. It was found that the organic matter of the substrate passes through three stages of transformation: hydrolysis of organic products → initial transformation → humification of lignin structures. There is a significant change in the ratio of the three main groups of humus in favor of humic acids at the third stage. In general, the system is tends to its most stable state: aromatic structures are copolymerized, the core of humic substances is densified, and humus gradually "matures".

Natural organic matter (NOM) plays a critical role in regulating the transport and the fate of organic contaminants in the environment. NMR spectroscopy is a powerful technique for the investigation of the sorption and binding mechanisms between NOM and pollutants, as well as their mutual chemical transformations. Despite NMR relatively low sensibility but due to its wide versatility to investigating samples in the liquid, gel, and solid phases, NMR application to environmental NOM-pollutants relations enables the achievement of specific and complementary molecular information. This report is a brief outline of the potentialities of the different NMR techniques and pulse sequences to elucidate the interactions between NOM and organic pollutants, with and without their labeling with nuclei that enhance NMR sensitivity.
