“…The use of the chelating effect of PCs is exemplified by the determination of Al localization in plant tissues by complexing to morin as the fluorochrome with subsequent detection by confocal laser microscopy [ 230 , 231 ]. This technique complements histochemical assays, where chelating dyes are used, and metal localization is examined by light microscopy [ 232 ] or visible reflectance and tristimulus colorimetry [ 233 ]. Tannic acid can be employed as a natural chelator for labile iron imaging in the prevention and treatment of iron-associated cancer or other iron-overload disorders [ 234 ]; Speciation of elements in plants: To establish the chemical forms of metals in which they are bound to plant chelators, the general analytical approaches of metallomics can be employed, along with a set of specific methods based on the structural peculiarities of these bioligands.…”

Plant adaptive strategies have been shaped during evolutionary development in the constant interaction with a plethora of environmental factors, including the presence of metals/metalloids in the environment. Among adaptive reactions against either the excess of trace elements or toxic doses of non-essential elements, their complexation with molecular endogenous ligands, including phenolics, has received increasing attention. Currently, the complexation of phenolics with metal(loid)s is a topic of intensive studies in different scientific fields. In spite of the numerous studies on their chelating capacity, the systemic analysis of phenolics as plant ligands has not been performed yet. Such a systematizing can be performed based on the modern approach of metallomics as an integral biometal science, which in turn has been differentiated into subgroups according to the nature of the bioligands. In this regard, the present review summarizes phenolics–metal(loid)s’ interactions using the metallomic approach. Experimental results on the chelating activity of representative compounds from different phenolic subgroups in vitro and in vivo are systematized. General properties of phenolic ligands and specific properties of anthocyanins are revealed. The novel concept of metallophenolomics is proposed, as a ligand-oriented subgroup of metallomics, which is an integrated approach to study phenolics–metal(loid)s’ complexations. The research subjects of metallophenolomics are outlined according to the methodology of metallomic studies, including mission-oriented biometal sciences (environmental sciences, food sciences and nutrition, medicine, cosmetology, coloration technologies, chemical sciences, material sciences, solar cell sciences). Metallophenolomics opens new prospects to unite multidisciplinary investigations of phenolic–metal(loid) interactions.

“…The full (diffuse and mirror) reflectance spectra of finely dispersed coal powders were obtained in the range of 400-830 nm using a Specord M40 spectrophotometer (Carl Zeiss, Jena), equipped with an integrating sphere for reflectance measurements according to a recommendation from [7]. The diffuse reflection coefficient of white light (R dif ) from the leveled surface of the coal powders was measured at 10 points by a pre-calibrated Reflectance Meter (ISO 2469: 1994).…”

This paper reports determining the grayscale intensity of macerals in the coal lump polished sections oriented along and across the layering of three main groups of sub-bituminous, high volatile bituminous, low volatile bituminous coals. All measurements have been performed in white, red, yellow, green, blue light. The influence of all selected factors and most of their combinations on grayscale intensity is reliable; the most pronounced effects are established for the optical filter color and the maceral type. Comparative analysis of the grayscale intensity data array with the spectra of full reflectance in the visible region and the coefficient of diffuse reflection in the white light of fine powders of the same samples has been carried out. Green light yields a very dark image of vitrinite and liptinite with the grayscale intensity approaching zero. In two of the six samples, the reflectance level of inertinite in yellow light is significantly higher than the grayscale intensity of white light. This anomaly is associated with a hypsochromic shift in the inertinite maximum absorption. The approach used is an alternative method for quantifying the relative changes in reflectivity and position of the diffuse spectral minimum without applying a microspectrometer.

“…Деякі властивості хелаторів установлено на прикладі фенольних сполук (Fedenko, 2000). За токсичної дії металів та металоїдів спостерігається переважна тенденція до підвищеного накопичення фенольних сполук як компонентів антиоксидантної системи захисту, що забезпечує баланс між продукуванням і детоксикацією АФК у рослинах (Fedenko et al, 2020). Дозова залежність цього процесу має характер періодичної параметри якої визначаються природою іона металу та його фітотоксичністю (Fedenko, Struzhko, 2009).…”

The negative consequences of various types of military activity on physical disturbances and chemical pollution of the environment are systematized. Factors of chemical pollution include potentially toxic elements, energetic compounds (explosives, fuels) and chemical warfare agents. According to the systematization of the available data on the long-term impact of military exercises and military actions on the territories of different countries on soil pollution, metal compounds dominate among potentially toxic elements, and organic pollutants dominate among energetic compounds. The combination of physical violations with multicomponent chemical pollution creates a specificity of the negative impact of the consequences of military activity on the natural environment compared to other anthropogenic factors. The following directions of research into the problem were noted: detection, distribution and ecotoxicology of chemical pollutants in natural environments, impact on biodiversity and vegetation dynamics, phytoremediation to reduce the level of chemical pollution, ecological and physiological factors of plant tolerance, degradation and detoxification of organic pollutants in plants. The tolerance of plants to the residues of explosive substances of various classes occurs due to the general pathways of biochemical transformation, which ensure the detoxification of organic xenobiotics. Taking into account the current state of the problem, literary data on the directions of research into the impact of military actions in Ukraine on the environment and the transformation of vegetation are summarized. Among these areas, the following were noted: assessment of damage caused by armed aggression to the natural environment; environmental monitoring of combat action; analysis of pollution of the natural environment; transformation of vegetation. Destructions of the natural environment as a result of combat action led to significant changes in vegetation, which are associated with ruderalization and adventization. The role of ruderal (including invasive) plants common in the flora of Ukraine under conditions of chemical pollution of habitats is analyzed. Increased tolerance of invasive plant species to high levels of metals and organic pollutants can be used for phytoremediation of disturbed areas, but will create a competitive advantage for more intensive spread compared to native species and new risks to phytodiversity.
