Invasions of adventive weed species are one of the leading factors in the transformation of agrobiocenoses and urban cenoses. Naturalization of new species leads to serious ecological, social and economic consequences. One of the dangerous invasive plants is ragweed (Ambrosia artemisiifolia L.), which is widespread in many countries of the world, including Russia. This weed plant causes significant economic damage and harmful impact on human health, since its pollen is a strong allergen. Modern technologies of agricultural production do not always give positive results in the fight against this plant. Therefore, it is necessary to develop new ecologically low-hazard methods to control it, aimed at reducing the productivity of pollen and seeds in order to reduce allergic diseases among people and limit the expansion of its range.

AbstractPine wilt disease causes ecological and economic damage in Japanese pine forests in spite of intensive effort to protect them from the pine wood nematode, Bursaphelenchus xylophilus. Pine trees infected with B. xylophilus emit a characteristic bouquet of volatile compounds bioactive to the vector beetle of the nematode, Monochamus alternatus, and potentially affecting symptom development inside the trees. To investigate the qualitative and quantitative properties of volatile compounds in the field, we profiled the volatile emissions in two Japanese black pine stands, one naturally suffering from pine wilt disease and the other artificially inoculated with B. xylophilus. In both pine stands, the emission of some terpenoids from the infected trees such as (−)-α-pinene, began to increase in summer, overlapping the oviposition season of the vector beetle, but peaked in the summer and autumn. These data suggest that the beetles may not necessarily depend on the tremendous quantity of volatiles alone when they search for suitable trees on which to oviposit.

The statistically significant geochemical dependences of the dynamic behavior of petroleum products in urban soils in the fuel filling station zone are considered, the areal of their distribution are determined. The techniques used make it possible not only to identify laterally manmade modules of environmental hazard (laterally module) when oil products come from fuel filling stations, but also to determine additional factors of unaccounted environmental risk, for example, the process of accumulation of heavy metals in the soil profile in excess of the standards on the resulting geochemical barrier in the form of oil products. The risk assessment of oil product supply facilities should be carried out taking into account the specifics of the distribution of toxicants in technogenically altered soils.

Heavy metals and other trace elements that are not subject to degradation are among the priority pollutants. Significant amounts of heavy metals and related elements with variable valence are deposited on the soil surface as part of aerosols. Accumulating in the soil, they are very slowly removed from it, only changing the level of content or the state during migration, turning the soil over time into a source of secondary pollution. In this regard, an extremely urgent task is to assess the territory, especially such a highly developed and densely populated area as the Moscow Region, in terms of its protective potential to heavy metal pollution. The paper proposes and tested an algorithm for the cartographic assessment of the protective potential of the soil and vegetation cover of the region using GIS analysis methods based on the database “Digital medium-scale soil map of the Moscow region” and a vector map of forest cover. The formula used for calculations includes data on the soil texture, the content of organic matter in soil, the position of the soil in the landscape and the degree of forest cover of the territory. According to the proposed approach, in the Moscow region, the soil cover, taking into account the forest cover, forms 4 groups according to the level of protective potential for contamination with heavy metals and metalloids. The maximum estimate was obtained for noneroded sod-podzolic soils of medium or fine texture, gray forest soils, chernozems and peat bog soils under forest vegetation (17 % of the area). Unerroded soddy-podzolic soils of varying degrees of podzolization and gleying (45 %) received an average rating. Even lower is the protective potential of 22 % of the territory represented by eroded gray forest soils, various sod-podzolic, alluvial and peat bog soils. This group is the most heterogeneous in terms of soil texture, organic matter content and degree of forest cover. The group with a minimum protective potential included eroded soils, soils of gully-girder complexes, sod-podzolic soils of coarst texture, as well as alluvial peat and peaty soils (about 16 %).

This paper reports the geochemical characteristics and environmental conditions of Cuchivero river sediments in Venezuela, depending on particle size, organic matter, organic carbon, nitrogen and total phosphorus, carbonates and heavy metals. The granulometry was typified by a predominance of sands with low organic matter (0.52 to 0.87%), organic carbon (0.06 to 0.09%) and carbonates content (0.54 to 2.61%) as well as high values of total nitrogen (602-985 mg / kg). The poor correlation between nitrogen, phosphorus and organic matter, suggests presence of nitrogen and total phosphorus of allochthonous origin and no Redfield organic matter. The average heavy metals in mg/kg, showed a descending concentration gradient, Fe (410)> Mn (63.14)> Zn (9.01)> Ni (3.38)> (2.21Cu)> Cr (2.09)> Co (1.13)> Cd (0.21) > Pb (0.07) mg / kg, with an association to the sands and carbonates, suggesting lithogenic origin. From the environmental point of view, there is no evidence of anthropogenic impact, as reflected by levels of organic matter and heavy metals which are below of the permissible values.

The present paper approaches a usual problem in the industrialised area, respectively Zlatna Area in Romania. The aim of this research is to establish the heavy metal soil contamination degree using modern research methods namely spectrometric and stripping methods. The results pointed out very high exceeding values, especially in the case of lead and copper, in the studied area. Moreover, the mobility and the availability of heavy metals decreases when pH increases. Findings suggest that the use of modern technologies have good results regarding the determination of the heavy metals in the soil.

In medical organizations special forms (approved by orders of the Ministry of health and the Central statistical office) are used to present the results of laboratory examination of the population for syphilis. Currently, these forms include laboratory technologies that do not meet modern standards. In 2018-2019 the normative documents, regulating the use of accounting forms of medical documentation in the public health system, and the practice of using forms with the results of laboratory examination for syphilis were studied in 35 branches of 3 medical organizations of the Lyubertsy district of the Moscow region and in 18 branches of Moscow city was conducted. It is established that in the medical organizations of Moscow and the Moscow region are used the different forms of the registration forms approved by orders of the Ministry of health of the USSR which have now become invalid. The structure of the forms with the results of the population survey for syphilis does not correspond to the applied modern technologies and standards of the survey. On the basis of requirements of modern regulatory documents two new forms of registration forms for the presentation of results of laboratory researches have been developed, within 1,5 years tested and offered for application: one form at screening of the population for syphilis and another - for performing verification examinations for diagnostics and the subsequent clinical and serological supervision.

Objective: To justify ecologically and geochemically rock dump processability of the Luhansk region coal mine for obtaining metals. Methods: The common methods of chemical and physicochemical analysis of debris, soil and vegetation samples as well as the valuation methods of ecological situation were applied. Results: The research data on migration of heavy metals to soils contiguous to dump and in the “soilplant” system were presented. The type of ecological situation when heavy metals pollute vegetation was established. The main cause of heavy metals migration is in the processes of chemical and biochemical oxidation of sulfide minerals being a part of stock debris as well as the processes of sulfuric acid formation. It was shown that debris contained a large number of metals with ferrous oxide, aluminum and silicon prevailing. While the debris of coal mines could be regarded as lean aluminum raw material. Practical importance: It was suggested to use natural processes for the formation of sulfuric acid in debris for the purpose of biochemical oxidation of aluminum as the main method of reducing the environmental impact and rational use of natural resources.
