We conducted a complex investigation of anthropogenic roadside phytocoenoses. For the study, 8 plots (birch and pine forests) were selected, close to roads in the south of Tyumen region within the five administrative districts: Uporovsky, Zavodoukovsky, Yalutorovskiy, Yarkovsky, and Tobolsk. As a result of the studies, 75 species of vascular plants from 21 families were noted in the plant communities. It was found that the majority of the total projective cover of the plant communities was provided by synanthropic species. In the synanthropic fraction of the flora, 33 species belonging to 11 families were identified, those with the most species being: Scrophulariaceae, Compositeae, Rubiaceae, Poaceae, Fabaceae, Polygonaceae, Umbellíferae. The index of synanthropization of the flora of the studied phytocenoses is in the range from 43% to 64%. Among the identified pollutants accumulated in the phytocenoses, the group of heavy metals was identified (Cr, Cu, Ni, Pb, Sr, Zn). Needles of Pinus sylvestris L. mainly accumulate Cr, Cu, Ni, Sr. The greatest concentration of Pb and Zn was found in the leaves of Betula pendula Roth. The content of other heavy metals in the leaves of Betula pendula Roth. during the growing season was relatively stable. Accumulation of heavy metals in the studied components of forest ecosystems can be displayed structurally: soil > leaves < phytomass (birch forests), soil < needles > phytomass (pine forests). Methodological approaches to conducting a complex of long-term observations of natural ecosystems have been formulated, substantiated and justified. To evaluate the absorption efficiency of heavy metals, the biological absorption coefficient was calculated. The obtained results can be used as a control in the study of migration and accumulation of heavy metals and for assessing the degree of anthropogenic load on phytocenoses of roadside ecosystems and predict the extent of probable changes in them. The forecast of the results will facilitate the elaboration of a necessary system of measures aimed at increasing the stability of plant communities.

Betula Pendula Roth

The influence of plant material fixation methods on the index of fluctuating asymmetry of Betula pendula Roth leaves is determined. The methods used were herbarization under pressure and leaves fixation in a solution of ethyl alcohol (45%). Biological material was collected in natural phytocenoses of the Pritalskaya zone of the Middle Urals and in technogenically formed territories, including soil contamination with heavy metals. The FA level of Betula pendula Roth leaf blades obtained on freshly harvested material increases in the gradient of toxic load and reflects a natural increase in soil contamination with heavy metals (Zn, Cu, Pb, Cd, etc.). The smallest deviation from the actual FA values obtained on freshly harvested material is given by a method of herbarization of leaves. The correlation coefficients are 0,940,99. Plant material fixation in an alcohol solution leads to more than 10-fold deviation of FA values from the real ones. The correlation between the studied morphological parameters of fresh and alcoholic leaf blades is 0,170,70. The signs distance between the bases of the first and second veins of the second order from the base of the leaf and angle between the main vein and the second vein of the second order from the base of the leaf are more distorted. Correction coefficients are proposed that allow to level out the differences in the FA level between the results obtained on freshly collected material and recorded by different methods. For the herbarization method, regardless of where the plant material is collected, the correction factor to be entered for the FA values of the fixed leaf blades is () 0,0004. For the method of leaves fixation in an alcohol solution, the coefficient value is () 0,00075 for material collected in undisturbed communities, and (+) 0,0045 for technogenically disturbed communities.

In this article the histological structure of gills and kidneys of the Prussian carp is considered and researched. The research was conducted in the waters of the Zaporizhian (Dnipro) reservoir, namely in the Samara Bay and the lower part of the reservoir (near the village of Viiskove) during 2017–2019. Previous studies have revealed the excess of maximum permissible concentrations of heavy metals in the water of the Samara Bay compared to the lower part of the Zaporozhian reservoir. High levels of nickel and cadmium were observed in the Samara Bay. Statistically significant differences were found between the content of copper, zinc, nickel, lead and cadmium in the two areas of the reservoir (p

Contamination of the food chain with heavy metals has become an urgent problem in recent years due to their potential accumulation in biosystems and is related to increased anthropogenic impact. This study assessed the levels of cadmium, lead, copper and zinc in cattle from the Novosibirsk, Krasnozersk, and Maslyanino regions of the Novosibirsk region and the Tselinny region of the Altai region. The aim of the study is to assess the influence of the ecological and geographical factors on the content of heavy metals in the spleen of Hereford gobies. Spleen samples were taken from 31 clinically healthy Hereford bulls aged 16-18 months. Sample preparation was carried out in accordance with GOST 26929-94 and 30178- 96. The determination of the chemical composition of the samples was carried out by atomic absorption spectrometry with flame and electrothermal atomization. The median values for the content of copper, zinc, lead and cadmium in the spleen of bull calves bred in Krasnozersky, Maslyaninsky, Novosibirsk and Tselinny regions were in the range of 1.6-1.8; 21.0-22.4; 0.06-1.45; 0.01-0.09 mg / kg. The phenotypic variability of the level of copper and zinc was relatively low, while that of lead and cadmium was high. The influence of the ecological and geographical factor was characteristic only for the level of cadmium. Significant differences in the concentration of cadmium in the spleen in animals raised in the Maslyanino region from those bred in the Krasnozersk and Novosibirsk regions were revealed. For copper, zinc and lead reference intervals were calculated - 0.60-2.92; 17.2-26.0; 0.019-0.218 mg / kg, respectively. They can serve as a rough guideline for Hereford cattle bred in the Krasnozersk, Novosibirsk, Maslyanino districts of the Novosibirsk region and the Tselinny district of the Altai region.

The effect of contamination of birch (Betula pendula Roth) leaves with heavy metals on the feeding of imagoes of the willow leaf beetle (Lochmaea capreae L.) was studied under laboratory conditions. The imagoes preferred feeding on leaves less contaminated by Cd, Mn and Zn. The Pb content was tolerated on all the studied levels. The repellent effect of Zn 8,000 &micro;g/mlin the Pb + Zn regime was compensated by Pb 500 <sup>&nbsp;</sup>in relation to Mn 10,000

Abstract The effect of alcohol and sugar concentration on the atomic absorption analysis of copper, zinc, nickel, chromium, lead, cadmium, and cobalt has been investigated. Sugar reduced the sensitivity of analysis but could be compensated for by using the method of additions. Interference from alcohol was avoided by introducing an evaporation stage, and the concentration of the above cations was determined by direct aspiration in 24 native and imported wines.

This study quantified the concentration of heavy metals (copper, zinc, cadmium, lead and nickel) in the biomass of two ant species, Camponotus atriceps and Dorymyrmex brunneus, which are dominant in forests and crop areas, respectively, in Sinop, Mato Grosso, Brazil. Ant sampling pitfall traps were used in both land use types, and metal concentrations in the biomass were obtained by means of atomic absorption spectrometry. The two species were selected because they were the most abundant in each land use type, considering the volume of biomass necessary for the chemical analysis. The results showed that with the exception of copper, heavy metals revealed higher concentrations in D. brunneus from crop areas than in C. atriceps from native forests. Such results are associated with the fact that the crop areas received high inputs of agrochemicals through the management of corn and soybean crops. Thus, ants are good indicators of contamination and environmental pollution in tropical regions, as the highest concentration of heavy metals was expected in the crop areas in relation to the adjacent forest area.
