“…In plants of Lathyrus maritimus, the concentration of metals also did not exceed phytotoxic values. Under these conditions, in addition to wind, a negative effect on plant growth and development can be a deficit of mobile forms of nitrogen, phosphorus and potassium compounds in foredune soils, low availability of humus and physical clay, as well as an increased amount of chlorides and sharp temperature difference in soil [15].…”

The article explores how location affected the dynamics of accumulation of ascorbic acid (AC) and oxidized forms of AC—dehydroascorbic acid (DAA) and diketogulonic acid (DKGA) in beach pea during ontogenetic development. Our analysis focuses on research of the ecological and geochemical conditions growing of the plant on the Curonian Spit. The level of hydrogen peroxide and the activity of enzymes that break it down were analyzed. Antioxidant activity and the total concentration of phenolics were evaluated in the leaves of beach pea on the leeward and windward sides of the foredune. It was established that the level of AC, DAA, and DKGA was higher in the plants growing on the windward side of the foredune. A higher concentration of peroxy compounds, which stimulate the biosynthesis of antioxidant enzymes (catalase, ascorbate peroxidase), polyphenols, and other low molecular antioxidants (AOA) was observed in the leaves of these plants. The plants on the windward side enter phenological stages one or two weeks later than their counterparts on the leeward side of the foredune do. There was a generally negative correlation between the temperature of the soil and the accumulation of ascorbate system acids in the leaves of the studied plants (r = −0.46/(−0.68), p < 0.05). The accumulation of low molecular antioxidants and enzymes in beach pea suggests their adaptation to the adverse conditions of the windward side of the foredune.

“…Urbanized territories are under strong technogenic pressure and all natural components of the urban ecosystem undergo a number of changes and acquire features that distinguish them from their natural counterparts. This leads to deterioration in environmental quality (Chupakhina et al, 2017;Maslennikov, 2020). In the Russian Federation, monitoring studies Science and Management Volume 16 Number 4, June 2021: 21-36 are being conducted in many cities to assess the ecological status of natural components in the urban ecosystem.…”

“…In each functional zone, plant and soil samples were taken from three sites. Soil samples were collected from the topsoil at a depth of 0-10 cm, using the envelope method (Chupakhina et al, 2017;Maslennikov, 2020). In the study areas, we established permanent research sites with an area of 100 m 2 .…”

“…Plant leaves were dried to a constant weight and ground to powder in a quartz mortar. The content of Zn in averaged samples was determined and expressed in μg/g of dry weight (Chupakhina et al, 2017;Maslennikov, 2020). "Averaged" means that combined plant material was collected from six to nine individual plants at each of the three experimental sites in a functional zone under study.…”

“…A strong technogenic impact was manifested not only in the soil, but also in the vegetation of the city. Plants are one of the most sensitive indicators of technogenic pollution of the urban environment and are the first line of protection from precipitation deposition, including metalcontaining aerosols (Chupakhina et al, 2017;Maslennikov, 2020).…”

The study aims to determine zinc accumulation in urban soil and in common urban landscape species of woodlands, bushes and herbaceous plants (22 species). Maximum metal concentration was observed in the soil of landscapes of industrial-utility and in residential multistore areas with increased transport load (125.7-154.7 mg/kg -1 ). Zinc (Zn) content of plant leaves in urban areas depended on its concentration in soil (r = 0.86-0.99, p<0.05) and the vegetation period. The minimum Zn content in plant leaves was observed at the beginning of the growing season (May), and later with increasing age and leaf blade area, the metal concentration increased, reaching a maximum in October. The highest rates of metal bioaccumulation were found in Syringa vulgaris (1.24 %), Rosa rugosa (1.17 %) and Populus nigra (1.1 %). These species will be useful for phytoremediation of areas moderately polluted with Zn. A decrease in Zn BAC and an increase in its concentration in the soil were identified in the majority of plant species. Plant species capable of limiting the entry of Zn from the environment were also identified.
