Opis:: Development of new and modification of existing chemicals, which act not only as binders, but also provide increased retention of fiber and other pulp components on the paper machine grid, accelerate pulp dehydration, and provide special properties (moisture resistance, heat resistance, improvement of other technical characteristics of paper and cardboard) of paper and cardboard, is an important and urgent task of chemical technology and ecology. This paper presents results of the corn starch modification with epoxypropyltriethanolammonium chloride, hexamethylolmelamine and hexamethylenetetramine. Modified starches provide the necessary strength indicators of cardboard from waste paper and low turbidity of wastewater. The obtained starches can be used in mills that use low-quality waste paper for the production of cardboard and paper products with the aim of saving fiber, reducing wastewater pollution and as a result reducing the negative impact on the environment.

Opis:: The water resources are the main component of technological processes occurring in industry; therefore, increasing the level of environmental safety, in particular, wastewater treatment without adverse impact on the environment and human health is relevant. The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company’s activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. The studies conducted with the aim of determining the motor transport enterprise sewage composition revealed an excessive content of polluting chemical substances, namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of using carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of wastewater of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing the environmental fees and penalties.

Opis:: While developing the projects for the construction of new and reconstruction of the existing roads, there is a probability of using privately owned land. In these cases, the mechanism of alienation of the private land plots is used to meet the public needs. Among the list of social needs, in the first place, there is a need for the land plots during construction, major repairs, reconstruction and maintenance of transport infrastructure objects, in particular roads. While designing the road construction and reconstruction projects, the technical-economic and transport-operational characteristics of the design object should be determined in conjunction with the protection of the environment and the rational use of natural resources. The article deals with the issues of assessing the impact of the road construction on the environment and the measures to reduce the level of pollution of the environment by introducing the environmental, technological, sanitary-technical and organizational measures.

Opis:: The article is devoted to the development of methodical approaches to the management of environmental risks due to pesticide contamination of agrocenoses. An assessment of ecological risks due to the use of pesticides was carried out at the scientific research field of the Skvirskaya research station of organic production of the IAP of the National Academy of Sciences during the growing seasons of 2019–2021. The methods of assessing the ecological risks of potential pesticide contamination of agrocenoses based on the indicators of the agroecotoxicological index (AETI) and the ecotoxic impact of harmful substances (E) were used on the natural environment. It was shown that the level of environmental risk due to the use of pesticides in the research field of the station according to the weighted average indices (AETI) is characterized as low – risk, and the environmental risk due to the pesticides using is minimal. According to indicators of ecotoxicity (E), the pesticides that were used are characterized as having a low potential ecotoxic risk of impact on agrocenoses of cultivated plants. However, the total pesticide ecotoxicological load (ΣЕ = 0.425 compared to the standard EDDT = 1) indicates the possibility of disruption of ecological connectivities in the agroecosystem. One of the elements of environmental risk management can be the assessment of the pesticide load on agroecosystems and considering of the territory ability to self-clean. In order to minimize the environmental risks of pesticide contamination of agrocenoses, measures should be taken to regulate the use of chemical plant protection agents. This can be done by banning or limiting the use of pesticides that have a high level of ecotoxicity and are persistent in the soil. This will contribute to increasing the ecological safety of agro-ecosystems and the natural environment.

Opis:: The tourism industry is concentrated within the boundaries of the Subcarpathia Forestry District of Ukraine. These are mostly resort complexes with recreation houses, hotels and restaurants. Since the issue of solid household waste processing has not been resolved in Ukraine, landfills are emerging near recreation facilities. Undoubtedly, such a situation contradicts the improvement processes, because landfills are objects of detonation of dangerous substances and compounds infiltrating into all components of the environment due to geochemical flows. The object of the conducted research was determination of chemical elements in the newly formed substrates on the surface of the following landfills, i.e. Bronytskyi, Stryiskyi, Boryslavskyi, which are located not far from the border with Poland within the tourist and recreational complex of the Lviv region of Ukraine, geographically belonging to the Subcarpathia Forestry District of Ukraine. It was established that the chemical elements of the toxic group and biogenic elements accumulate. The traces of individual elements were also determined. The Bronytskyi landfill is the most polluted with the following chemical elements: Pb (3.56–4.06 mg/kg), Zn (2.84–3.67 mg/kg), Gd (0.021–0.033 mg/kg), P (457.3–609.7 mg/kg), K (9.7–14.6 mg/kg), Ca (174.7–237.7 mg/kg), Ga (3.58–5,98 mg/kg), La (1.09–1.24 mg/kg), Y (0.013–0.014 mg/kg), Cd (0.15–0.176 mg/kg), Sn (0.013–0.018 mg/kg), Nd (0.029–0.046 mg/kg), Eu (0.022–0.036 mg/kg) and Th (0.05–0.078 mg/kg). The site of the Boryslav landfill is most polluted in the western side - Fe (16.06–19.72 mg/kg), Cu (0.37–0.43 mg/kg), Gd (0.003 mg/kg), Si (43–58.2 mg/kg), P (782.4–995.5 mg/kg), Ca (88.6–104.7 mg/kg), Mn (1.7–2.7 mg/kg), Sc (0.009 mg/kg), Cr (1.069–1.255 mg/kg), Y (0.015–0.016 mg/kg), Nd (0.016–0.018 mg/kg). In the eastern side of the Stryi landfill the presence of the following elements is most evident - Fe (18.98–27.97 mg/kg), Ni (0.09–0.21 mg/kg), Zn (0.14–0.19 mg/kg), Pb (0.05–0.1 mg/kg), Al (1.6–2.0 mg/kg), P (718.1–652.5 mg/kg), Mn (2.5–3.5 mg/kg), Ga (0.01 mg/kg), La (0.02–0.04 mg/kg), Cr (0.009–0.013 mg/kg), Ge (0.214–0.551 mg/ kg), Cd (0.014–0.02 mg/kg), Nd (0.017–0.037 mg/kg), Th (0.009–0.016 mg/kg). Such a detailed chemical analysis for the presented research objects was carried out for the first time. Determining of the chemical content of the newly formed substrate is important from the point of view of environmental protection solutions implementation.

Opis:: The paper considers the current problem of improving the quality of atmospheric monitoring. The paper aimed at conducting a monitoring section of the existing situation in the studied territories in St. Petersburg. The following study methods were described: gravimetric, electrochemical, and chromatographic. The analysis of samples was carried out on the following laboratory facilities of the mobile environmental laboratory: PU-3E aspirator, ECOLAB portable gas analyser, DUSTTRAK 8533 dust analyser, portable gas chromatograph FGKh-1, professional weather station. The study consisted of two parts and was carried out in two districts of the city: Novosmolenskaya Embankment of the Smolenka River (Vasileostrovsky District) and the banks of the Volkovka River (Frunzensky District). As a result of the study, the concentrations of nitrogen dioxide, carbon oxide, suspended solids and volatile organic compounds in the air of the studied districts were measured. The obtained values were compared with the maximal single limiting concentration (LMCm.s.) and assumptions were made about the possible sources of pollution. In the territory of Novosmolenskaya Embankment, the concentration of nitrogen dioxide varied from 0.211 mg/m3 to 0.472 mg/m3, which means the exceedance of LMCm.s. The maximum permissible concentration of the volatile organic compounds (VOC) content in air was exceeded by several orders of magnitude. No exceedance of LMCm.s. was detected for the content of carbon oxide and suspended solids in the air. The empirical data was used to build the air pollution content maps and to calculate the atmospheric pollution index in the studied territory.

Opis:: The development of the infrastructure of the oil and gas complex is one of the most significant factors of negative impact on the environment. The most efficient way to drill wells is cluster drilling, which currently accounts for 95% of all operations carried out in fields. In the process of oil and oil products production, toxic drilling waste is generated at the well pad, which is then placed in sludge pits (sludge storage). The aim of the study was to select the methods for drilling waste utilization based on the results of environmental radiation analysis. Within the framework of the study, the following tasks were solved: radiation monitoring of drilling waste was carried out at the “Progress-2000” spectrometric complex; analyzed the physical and chemical composition of drill cuttings; a comparative analysis of the samples under study was carried out in accordance with the normative indicators; methods of utilization of drilling waste are proposed.
