[Ab] Resumo:The paper presents the results of a study of the qualitative composition and quantity of pollutants in atmospheric air in the course of operational wear of the road surface, braking system and tire treads of automobiles. On the basis of field research in samples ofatmospheric air ofthe city of St. Petersburg there were identified compounds of heavy metals andpolycyclic aromatic hydrocarbons (PAHs). There was established the dependence of the level of air pollution on traffic flows in locations of the city. Pollutants were shown to enter the air environment mainly in the form offine dust particles. There was justified the need for the control ofproducts of wear the road traffic complex in the hygienic assessment of the quality of ambient air ofmegalopises.

[Ab] Resumo:The paper presents data on the hygienic assessment of the content of heavy metals and petroleum products in the soil on the territory of oil-producing areas of the Republic of Tatarstan. The average total content of lead (10,1 mg/kg), cadmium (0.073 mg/kg), manganese (792.4 mg/kg), cobalt (14.2 mg/kg), chromium (87.6 mg/kg), nickel (65.2 mg/ kg), arsenic (8.0 mg/kg), copper (36.6 mg/kg) and zinc (521 mg/kg) in soil for agricultural purposes near objects oil production was shown not to exceed the established hygienic standards. Soil contamination with oil products leads to an increase in its toxicity and mutagenicity. Soil contamination with oil products at the level of as low as 30 mg/ kg leads to the gain in its toxicity (low toxicity) and mutagenicity (average) (specific gravity of germinated seeds was 70.7±0.67%, aberrations - 1.78±0.19%).

[Ab] Resumo:Dumps of quarries for the extraction of copper pyrite in Urals region of the Bashkortostan Republic are the problem object, which represents a main technogenic source of environmental pollution. Soils of Sibaisky quarry dumps are characterized by the elevated content of heavy metals relatively to maximum permissible concentrations and regional geochemical background. In sanitary hygienic evaluation of the pollution by studied technosols according to the total pollution index (Zc) it was revealed that according to the content of total forms studied technosols are referred to moderately hazard, while in regards of the same index concerning the content of the mobile forms technosols are referred to the category of hazardous. In this regard, in plant products grown in the area adjacent to the dumps, there was revealed an excess on cadmium. The biological activity of soils is very low, due to the low microbial community development. Soil formation in the dumps is almost not expressed, appearing in the formation of low-thick underdeveloped humus horizon with a little diversity of species and projective cover. Sanitary-hygienic situation in conditions in the quarry dump area is unfavorable, that does not allow newly formed soils to carry out environmental functions effectively

[Ab] Resumo:This study is devoted to the investigation of quantitative and qualitative composition and distribution of polycyclic aromatic hydrocarbons (PAHs) in urban soils on the example of recreational, residential and industrial areas of Saint-Petersburg (Russia). The evaluation of soil contamination levels with heavy metals and metalloids of the first and second classes of hazard is given as well. Total PAH content in soils of the studied area in most cases exceeds international soil quality guideline values (1 mg/kg), varying from 0.67 to 17.45 mg/kg. In most samples benzo[a] pyrene concentrations were found to be higher than MPC for this substance in soil. Calculated BaP-equivalents of PAHs indicate to the high carcinogenic risk for health, associated with soil contamination. Mean PAH concentrations in soil differ authentically between various types of functional zones and in the whole of the city. The significant positive correlation between soil organic content and PAH levels in soils was revealed in most samples. Calculated values of the total index of soil contamination (Zc) by heavy metals and metalloids were characterized by low values (47.28-121.14), that corresponds to the category of dangerous pollution (32 < Z < 128).

[Ab] Resumo:Exploration and development of mineral deposits in the Transurals of the Republic of Bashkortostan are accompanied by a comprehensive environmental impact. Ones of the most vulnerable elements of the landscape are the surface water bodies used for fishery purposes, recreation and household needs of the population. Extraction and processing of ores lead to the contamination of aquatic ecosystems by heavy metals (HM), which by passing into a pond, can actively be involved in the cycling of matter and migrate via food chains to the human under the consumption of fish products. Possessing by cumulative properties, HM can express mutagenic, teratogenic and carcinogenic properties. The aim of research was the study of the impact of mining facilities on the content of the priority HM in the components of river ecosystems in the Transurals of the Republic of Bashkortostan and the development of a complex of preventive measures on the improvement of the human environment. There was studied the content of Zn, Cu and Cd in the water, bottom sediments and phytomass of Elodea canadensis Michx. The measurements of mass concentrations of metals were performed by stripping voltammetry with the use of the STA device. The results showed that for the cross-sections there is typical the following descending series of elements in the river components: Zn > Cu > Cd. In water samples there is observed the exceedance of standards for water bodies of potable, cultural and community water use and fishery basins. The concentration of zinc varies in the range of 0.016-5.24 mg/dm; copper - 0.0024-0.095 mg/dm; cadmium - 0.0001-0.019 mg/dm. In bottom sediments, in general, the content of metals in comparison with control plots is increased to the tenfold value. The meaning of mobile forms of zinc in the ground varies in the range of 0.81-9.62 mg/kg; copper - 0.12-18.69 mg/kg; cadmium - 0.00013-0.092 mg/kg. The zinc concentration in above-ground phytomass of Elodea canadensis compared to control increases by 2-3.5 times, copper - 4-8 times, cadmium - 2-7 times. Univariate analysis of variance confirmed the accuracy of the impact of the degree of contamination on the accumulation of metals by Elodea canadensis. The results testify to the potential danger to health of water bodies of the region's population.

[Ab] Resumo:In August 2015 there were executed investigations on the study of the soils diversity of the Yamal-Nenets Autonomous Okrug. One of the directions of this work got be the study of urban soils of settlements of the Yamal-Nenents Autonomous Okrug. The sectors for the observation were settlement of Harsaim, village Aksarka, city of Salekhard, settlement Harp and city of Labytnangi. About 20 soil samples were collected during the field work. Samples were collected from a depth of 0-5 cm and 5-20 cm. Heavy metals (HM) were detected with the use of X-ray fluorescent analyzer "Spectroscan-MAX". The HM content values were compared with the corresponding Approxible Permissible Concentrations and Maximum Allowable Concentrations (MAC) adopted in Russia. Hydrocarbons content was determined by gravimetric method. Values of the hydrocarbons content in studied soils were compared with the existing regulations of the Russian Federation. The levels of soil contamination by hydrocarbons were determined. The study of soil samples from different settlements allowed to reveal characteristic features of soil contamination of separate settlements by HM and hydrocarbons and to compare them against each other. The vast majority of samples are characterized by arsenic exceedance of MAC, which should indicate to a high regional background of this element. For a more adequate assessment of the Zc meaning as the value of the total pollution index of soils there were used not only arithmetical average values of the coefficients of the chemical composition concentration (Kc), but also their average geometric values. According to levels of total soil contamination most of soil samples are characterized as non-hazardous (Zc<16). Calculation of soil pollution index showed that the most of soil samples have values less than 1. It characterizes soils as unpolluted. Statistical processing of obtained data in the media of the analytical software interface STATISTICA 10 showed a statistically significant difference in the content ofHM and hydrocarbons for the layer of 0-20 cm of the soils for three elements (Cu, Zn, Ni).

[Ab] Resumo:Impact of calcium nutrition (pre-culture on solid medium with standard or elevated Ca dose, i. e. 0.17 and 4.40mM marked as low and high Ca) on acute metal toxicity (Cd, Mn and Pb, 24h of exposure to 10µM) in freshwater green alga Scenedesmus quadricauda was studied. Surprisingly, Ca content differed only slightly between low and high Ca samples and applied metals rather suppressed its amount. Na content was higher in metal-exposed high Ca samples, indicating that Ca/Na ratio may affect accumulation of metals. Content of heavy metals increased in order Cd < Mn < Pb and high Ca samples contained less metal than low Ca samples at least in absorbed fraction. Accumulation of ascorbic acid and thiols (GSH - glutathione and PC2 - phytochelatin 2) was affected mainly by Cd, GSH also by Mn and PC2 by Pb with often significant differences between low Ca and high Ca samples. Calcium nutrition also affected responses of algae to metals at the level of antioxidative enzyme activities (SOD, APX, and CAT) and elevated values were typically found in high Ca samples while ROS (hydrogen peroxide and superoxide radical) were mainly depleted in Mn treatment. These data confirm that Ca nutrition affects accumulation of metals in algae and metabolic parameters as observed in vascular plants but, unlike them, rather Ca/Na ratio than absolute Ca content seems to regulate the uptake of metals.

[Ab] Resumo:Industrialization and urbanization have posed serious threats to the environment. Excessive release of heavy metals from industrial effluents and overuse of pesticides in modern agriculture are limiting crop production by polluting environment and deteriorating food quality. Sustaining food quality under heavy metals and pesticide stress is crucial to meet the increasing demands for food. 24-Epibrassinolide (EBL), a ubiquitously occurring plant growth hormone shows great potential to alleviate heavy metals and pesticide stress in plants. This review sums up the potential role of EBL in ameliorating heavy metals and pesticide toxicity in plants extensively. EBL application increases plant's overall growth, biomass accumulation and photosynthetic efficiency by the modulation of numerous biochemical and physiological processes under heavy metals and pesticide stress. In addition, EBL scavenges reactive oxygen species (ROS) by triggering the production of antioxidant enzymes such as SOD, CAT, POX etc. EBL also induces the production of proline and soluble proteins that helps in maintaining osmotic potential and osmo-protection under both heavy metals and pesticide stress. At the end, future needs of research about the application of 24-epibrassinolide have also been discussed.

[Ab] Resumo:The use of inappropriate experimental conditions for examining trace metal phytotoxicity results in data of questionable value. The present study aimed to identify suitable parameters for study of phytotoxic metals in nutrient solutions. First, the literature was reviewed to determine the concentration of six metals (Cd, Cu, Hg, Ni, Pb, and Zn) from solution of contaminated soils. Next, the effects of pH, P, Cl, NO , and four Fe-chelators were investigated by using thermodynamic modelling and by examining changes in root elongation rate of soybean (Glycine max cv. Bunya). The literature review identified that the solution concentrations of metals in soils were low, ranging from (µM) 0.069-11Cd, 0.19-15.8 Cu, 0.000027-0.000079 Hg, 1.0-8.7 Ni, 0.004-0.55 Pb, and 0.4-36.3 Zn. For studies in nutrient solution, pH should generally be low given its effects on solubility and speciation, as should the P concentration due to the formation of insoluble phosphate salts. The concentrations of Cl, NO , and various chelators also influence metal toxicity through alteration of metal speciation. The nutrient solutions used to study metal toxicity should consider environmentally-relevant conditions especially for metal concentrations, with concentrations of other components added at levels that do not substantially alter metal toxicity.
