Heavy Metals In Soils And Plants Of Urban Ecosystems (On the Example of the City of Yoshkar-Ola)

Concentrations of heavy metals in Southern Kuzbass urban soils affected by coal mining industry and sity boilers were studied. The risks of toxic effects of elements found in soils as a result of geochemical sampling (200 samples) were identified. The hazard ratio during the intake of elements - toxins into the human body orally and via inhalation was calculated. Analysis of uncertainty in the estimation of the average daily doses was carried out. The obtained risk parameters fall into the category of permissible or acceptable. The primary contribution to the total hazard ratio is made by the manganese, cobalt, copper, and arsenic. These elements show special features of the soil in the affected area of coal mining, urban boilers everywhere and the activity of repair — metallurgical and foundry businesses locally. No pronounced differentiation of the city areas according to the value of the hazard ratio was discovered.

Heavy Metals In Soils

The paper studies heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. An adverse effect of railway transport on adjacent territories is shown. Railway transport and subjects of its support are permanent sources of pollution. Long-term emissions to the air are reflected by essential accumulation of tocsins in the top horizons of the soil. The authors reveal the amount of heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. To identify the coefficient of heavy metals concentration in soil samples of 8 trial areas of technogenic and anthropogenic zones of the city were analyzed. To identify local technogenic anomalies concentration coefficients were calculated. The authors concluded that the territory of the train removal station Ussuriysk JSC Russian Railways was very polluted. The south of the railway station is characterized by an average pollution level. The authors revealed high concentrations of Zn, Mn, Fe, Cu and Pb in soils of the trial sites with a high transport loading.

Woody plants are able not only to absorb metals of anthropogenic origin, but also to deposit their significant quantities in wood, leaves, and thereby temporarily remove them from the cycle of substances of urban ecosystems. The paper compares the content of heavy metals – Cu, Zn, Pb, and Cd in the leaves of the bioindicator species Pоpulus рyramidalis Roz and their mobile forms in soils collected from 6 test locations from various functional zones of the Southern industrial district of the City of the Cherkassy. Soil-geochemical associations of Cu, Zn, Pb and Cd content in the investigated locations indicate that the main source of Zn, Cu is the emissions of of the Cherkassy thermal power plant, and Pb, Cd – of urban transport. According to the total accumulation in the leaves of P. pyramidalis. The heavy metals are located as follows: Pb> Cd> Cu> Zn. It was established that the content of mobile forms of Cu, Zn, Pb, and Cd in the soils of the experimental sites was several times higher than background values, and the coefficient of biological accumulation in the leaves fluctuated in insignificant limits. According to the results of indicators of the accumulation coefficient, the leaves of P. pyramidalis have low bioavailability in Cu and Zn, and the availability of Pb and Cd approaches the average. The obtained data can be used for the creation and reconstruction of green plantings of urban transport highways, sanitary protection zones of industrial sites of enterprises, recreational areas, squares.

Heavy Metals In Soils

The article presents the results of studies on the assessment of heavy metal pollution of soils and epiphytes in of the city of Izhevsk. Objects of research: soils of near-trunk circles of black poplar (Populus nigra L.) and epiphytic moss of Schreber's pleurotium (Pleurozium schreberi (Willd. Ex Brid.) Mitt.). To assess the pollution, the magnetic susceptibility of soils and mosses was determined, as well as the average total content of heavy metals in the samples under study. The relationship between the content of heavy metals and the magnetic susceptibility of soils and epiphytes has been determined. A correlation was revealed between the total content of Zn, Cr, Fe, V in soils and in mosses, which indicates air pollution of soils.

The growth of technogenic impact on urbo-landscapes is accompanied by man-made contamination of the environment. Among the most toxic and widespread pollutants of the urban ecosystems an important place belongs to heavy metals. The soil is the main source of accumulation of heavy metals and its uptake by the biota objects, including plants. Elevated concentrations of heavy metals in plant products, in turn, lead to intoxication of people and animals. Toxicity of heavy metals due to their biological activity and availability, resistance of their compounds in the environment, the possibility of small concentrations cause significant negative effects. For the city of Cherkasy the main polluters of the environment with heavy metals are the subsidiary of Cherkasy thermal power (accounting for 75% of the total amount of heavy metals emitted, and contribution of thermal power for emission of Pb, Cu and Zn reach 85%) and automobile transport. It should be noted that the city of Cherkasy (population 285.000 people) is an important economic center of Ukraine, with well-developed chemical and automobile industries. With atomic absorption spectroscopy the content of heavy metals (Cu, Zn, Pb and Cd) in the leaves of bio-indicator species Tilia cordata Mill. and soils from 24 localities of the city of Cherkassy was examined. The general content of the leaf biomass and soils from different localities of the degree of technogenic pollution of heavy metals are arranged in a sequence Zn > Cu > Pb > Cd. In the city the content Pb and Cd in soils were below the MPK (maximum permissible concentration). Apparently, the content of copper and zinc soils, first of all, caused by pollution of chemical plants emissions, lead, due to industrial and transport factors and cadmium, of the distances to highways. The data obtained suggest that small-leaved linden (T. cordata Mill.) is as a representative species for bio-indication of heavy metals pollution in urban territories
