“…The dandelion leaves contained 6% more zinc and 28% more copper than those of sea buckthorn. It has been reported that the iron level in the leaves of dandelion ranged from 0.16 to 46.2 mg 100 g −1 DM, zinc ranged from 2.14 to 6.93 mg 100 g −1 DM, and copper ranged from 0.50 to 1.82 mg 100 g −1 , depending on the habitat (Giacomino et al 2016), which is consistent with the results of this research. In the study of Popescu et al (2010) where mineral concentrations in plant leaf, fruit, and vegetable material were determined, the highest levels of iron and zinc were found in sea buckthorn leaves.…”

The aim of this study was to determine the chemical composition and antioxidant activity of dandelion [Taraxacum officinale (Weber) ex Wigg.] and sea buckthorn (Hippophae rhamnoides Rousi) leaves grown in Poland (53°20′35″N, 14°58′10″E). Both the leaves of sea buckthorn and common dandelion were found to be a very good source of essential nutrients and elements. The dandelion leaves contained significantly more protein, fat, and crude fibre than those from sea buckthorn. Dandelion leaves also contained more phosphorus, potassium, calcium, iron, and zinc. Although the dandelion leaves were a good source of biologically active substances, sea buckthorn leaves exhibited a significantly higher level of antioxidant activity as measured by ABTS. Dandelion leaves were richer in tocopherols, thiamine, riboflavin, and niacin while the sea buckthorn leaves contained higher levels of L-ascorbic acid.

“…In our study, metal concentrations in plant samples were significantly correlated with the distance to the road, regardless of the plant species considered. Our data showed considerably higher Cr, Ni, Zn concentrations in the direct proximity to the road, when comparing to the figures reported by Kovacik et al [36] for the vicinity of traffic roads in Kosice and by Giacomino et al [38] for Italian province of Cuneo. The data referring to the distance of 300-600 m matched the data reported by Kabata-Pendias and Dudka [29] for Poland, Czarnowska and Milewska [37] for Warszawa, Ligocki et al [34] for Szczecin.…”

“…The mean metal concentrations in dandelion collected in Poland and reported by Kabata-Pendias and Pendias [45] are: 0.8 μg Cr/g, 9.4 μg Cu/g, 3.4 μg Ni/g, 1.1 μg Pb/g, and 45 μg Zn/g. In contrast to the Pleurozium schreberi moss species, there are many studies referring to roadside metal pollution monitoring, using the Taraxacum officinale species (Czarnowska and Milewska [37] for Warszawa, Djingova et al [33] for highways in Germany, Ligocki et al [34] for Szczecin, Giacomino et al [38] for Cuneo province, Italy and Kovacik et al [36] for Kosice, Slovakia). Those results considerably exceeded mean values for Poland reported by Kabata-Pendias and Pendias [45] in the case of Cr, Ni and Pb, regardless of the distance from the road.…”

The aim of this study is to test two plant species, the common dandelion Taraxacum officinale and moss Pleurozium schreberi, as bio monitors of trace metal pollution emitted by motor vehicles. The samples of the moss Pleurozium schreberi (green segments) and the common dandelion Taraxacum officinale (leaves) were collected within 12 transects along the state road No. E77 near Chyzne, Sothern Poland. The transects were located on the eastern and western side of the road (downwind and upwind towards prevailing winds), at the following distances from the road: 5, 50, 100, 300 500 and 600 m. Total concentrations of Cr, Cu, Ni, Pb, Sb and Zn in the plant material were determined. The studied species accumulated trace metals in the similar amounts. Statistically significant differences in metal concentrations between two plant species were observed only in the case of Cu and Pb. Copper concentrations were higher in the common dandelion, while the moss Pleurozium schreberi accumulated considerably higher amounts of Pb. There is a statistically significant negative correlation between the trace metal concentrations in plants and the distance to the road. There are also statistically significant differences in concentrations of Cr, Cu, Ni, Pb and Zn in the common dandelion between the samples collected from the opposite sides of the road: upwind/downwind towards the prevailing wind direction at the distance up to 300 meters. The concentrations are higher on the downwind side of the road.

Road transport is one of the main pollutants of atmospheric air and soil in modern cities, therefore, an important issue is the comprehensive diagnosis of the state of the environment, which can be carried out by phytoindication methods, and which make it possible to comprehensively assess the environmental risks of the roadside environment for living organisms. The article analyzes the morphological and physiological changes of Taraxacum officinale Web. that occurred under the influence of vehicle emissions. For research, we chose a territory with significant aerotechnogenic loads due to both stationary sources of pollution and traffic flows –the southwestern district of the city for the analysis of plants, the following indicators were studied: mass of plants; leaf length;proportion of altered forms; ascorbic acid content; chlorophyll concentration. In the study, biometric, spectrophotometric and statistical methods were used. The results of the studies showed that in all plants inhibition of parameters was observed in comparison with the control samples. An analysis of the tightness of the relationship between the morphophysiological parameters of the plant, the traffic intensity and the distance from the road were influenced by the average mass of plants (r=0.97) in the area with heavy traffic, the content of chlorophyll (r=0.92) in the same area, the proportion of altered forms (r=-0.94). The correlation coefficient of the proportion of altered forms is negative, since the number of altered forms decreases with increasing distance from the road. It was found, that content of chlorophyll depends on traffic intensity and the distance from the road (the correlation coefficient ranged from 0.88–0.97). Indicators of leaf length and vitamin C content turned out to be less informative, since there is no clear relationship between these indicators and distance from the road (r=0.54), although with an increase in the distance from the highway, there is a slight increase in leaf length, but the content of vitamin C did not show depending on the distance to the road. The further developments lies in the refinement of the information content of such an indicator as the content of ascorbic acid in order to use it to indicate invisible changes in the vegetation cover.
