“…It has been found that the amount of chlorophyll pigments is also related to the physiology of stress. In response to an increase in ROS caused by the influence of BaP, a dose-dependent increase in the concentration of carotenoids occurred [ 15 ]. In the present study, the decrease in total chlorophyll did not have a clear pattern, but general trends were observed toward a decrease in the level of photosynthetic activity due to the accumulation of ROS products in the chloroplasts [ 16 ].…”

Benzo[a]pyrene (BaP) is noted as one of the main cancer-causing pollutants in human beings and may damage the development of crop plants. The present work was designed to explore more insights into the toxic effects of BaP on Solanum lycopersicum L. at various doses (20, 40, and 60 MPC) spiked in Haplic Chernozem. A dose-dependent response in phytotoxicity were noted, especially in the biomass of the roots and shoots, at doses of 40 and 60 MPC BaP and the accumulation of BaP in S. lycopersicum tissues. Physiological and biochemical response indices were severely damaged based on applied doses of BaP. During the histochemical analysis of the localization of superoxide in the leaves of S. lycopersicum, formazan spots were detected in the area near the leaf’s veins. The results of a significant increase in malondialdehyde (MDA) from 2.7 to 5.1 times, proline 1.12- to 2.62-folds, however, a decrease in catalase (CAT) activity was recorded by 1.8 to 1.1 times. The activity of superoxide dismutase (SOD) increased from 1.4 to 2, peroxidase (PRX) from 2.3 to 5.25, ascorbate peroxidase (APOX) by 5.8 to 11.5, glutathione peroxidase (GP) from 3.8 to 7 times, respectively. The structure of the tissues of the roots and leaves of S. lycopersicum in the variants with BaP changed depending on the dose: it increased the intercellular space, cortical layer, and the epidermis, and the structure of the leaf tissues became looser.

“…This is especially pronounced for the carcinogen of the first hazard class BaP. Artificial soil contamination of Haplic Chernozem by BaP in the amount of 20 ng g −1 led to disorientation in the root architecture in spring barley (Poaceae family), which subsequently led to losses in yield and quality of the cultivated crop [61].…”

Based on 10 years of environmental monitoring located around the emission zone of an electricity supplier, the main regularities have been studied for the content of heavy metals (HMs), such as Pb, Cd, Zn, Cu, Ni, Mn, and Cr, and 16 priority polycyclic aromatic hydrocarbons (PAHs) in the soils of agricultural landscapes and their accumulation in Triticum aestivum. It has been shown that one of the most significant factors for the pollutants accumulation in soils and plants was the prevailing wind direction on the territory and atmospheric transfer of the dust particles of the enterprise with adsorbed pollutants. As the content of pollutants in the soil increased, their accumulation in Triticum aestivum increased with each season to a level exceeding maximum permissible concentrations (MPC), especially for Pb, Cd, and benzo[a]pyrene (BaP). The unambiguous influx of pollutants from the soil into the roots and further into the aboveground organs of the plant was typical only for Mn, Cr, and BaP, and the accumulation of other studied pollutants can be explained by their foliar influx. It has been established that Triticum aestivum was a more tolerant plant with respect to heavy metals pollution than PAHs.

“…Regardless of the noticeable changes in the morphometric characteristics of plants, the BaP concentration at the level even 20 ng g −1 in the soil showed changes at the ultrastructural level of cellular-subcellular organization. At a concentration of 200-400 ng g −1 BaP in the soil, multiple changes were noted in the vacuole, cytoplasm, nucleus, and mitochondria (Fedorenko et al 2021). The disorganization of the nucleus, mitochondria, and chloroplasts were also observed in the mangrove plant tissues grown on fuel oil or oil polluted medium (Naidoo 2016;Naidoo and Naidoo 2017).…”

“…In the Netherlands, the sum of 10 PAHs concentrations, including BaP, should not exceed 1000 ng g −1 (VROM 1994) and 300 ng g −1 according to Swedish standards (Brezet 2000). However, plant dysfunction begins when they grow in soil contaminated with as little as 20 ng g −1 BaP (Fedorenko et al 2021).…”

Hyperspectral imaging is a newly developed approach to estimate the current state of the plants and to develop the methods of soil and plant ecological state improvement under the effect of different sources. The study was devoted to the novel approach of hyperspectral imaging application in the case of persistent organic pollutants (POP) uptake by plants. Hordeum vulgare L. was used as a test plant and grown on the soil artificially contaminated by benzo[a]pyrene (BaP) in the doses of 20, 100, 200, 400, and 800 ng g −1 , which corresponds to 1, 5, 10, 20, and 40 maximum permissible concentrations (MPC) and correlates with the level of soil pollution near industrial facilities in the Rostov Region (Russian Federation). It was analyzed a group of indexes responsible for plants stress, consists of broadband greenness group, narrowband greenness group, light use efficiency group, and leaf pigments group. Benzo[a]pyrene had a stronger effect on the efficiency of the photosynthesis process than on the content of chlorophylls. In the phase of active adaptation to stress in H. vulgare, the content of photosynthetic pigments was increased. The proposed method for selecting spectral profiles by cutting off profiles that do not belong to a plant, based on the NDVI value can be effectively used for the estimation of the plants stress under the BaP contamination and for future perspectives in the most suitable way for the application of the plant's growth stimulants.
