The organization of management in conditions of emergency relief operations in the Pavlodar region
Annotation:

The work analyzes the emergency situations that occurred on the territory of the Pavlodar region. The main causes of emergencies of natural and man-made nature are presented. The article contains the results of the analysis of the effectiveness of management in a safety-related system in the Pavlodar region and recommendations for improving the safety-related system during the emergency relief operations.

Innovative technologies for enrichment of flour from wheat grain
Annotation:

The technogenic impact on the ecological environment led to a decrease in the amount of natural food consumed and a change in its qualitative composition. The article discusses the innovative direction – enrichment of food with micronutrients. New types of bread with functional properties for mass nutrition are developed.

Research of fungal diseases of herbaceous plants exposed from Aksu Ferroalloy Plant
Annotation:

Main problem: Technogenic "metamorphosis" of vegetation near such large industrial facilities as Pavlodar is considered to be the result of various active chemical and mechanical factors provoked by economic activities associated with the influence of emissions from industrial companies. The effect of anthropogenic impacts on vegetation in all regions of Kazakhstan varies and is largely dependent on the economic development of the territory, but in any case, the end result of this impact is the change in the vegetation, causing violations of with structure, reduced vodorazdelnaya flora and productivity of communities. This, in turn, can cause infection of herbaceous plants with pathogenic fungi, which then carry with them: a decrease in the intensity of plant growth, a deterioration in their decorative qualities, a decrease in the survival of the biological species. Purpose: to study the types of fungi-pathogens of phytopathogenic diseases and to determine the degree of modification of the plant component, which is under intense negative technogenic influence from the Aksu Ferroalloy Plant (AFР). Мethods: For the experimental study, species of plants such as: Artemisia dracunculus L; Artemesia vulgaris L; Atriplex fera L; Atriplex patula L; Artemisia annua L were selected for the content of fungipathogens of phytopathogenic diseases. Results and their significance: This experimental study was aimed at the presence of fungi-pathogens of herbaceous plants as a result of human impact, occurring near the industrial zone "AFР". The composition of fungi-pathogens of herbaceous plants collected in this industrial zone was considered and studied. According to the results of an experimental laboratory study, phytopathogenic fungi of herbaceous plants belonging to 1 ordo, 1 familia, and 4 species were found.

Some aspects of justification of acceptable risk levels in oil refineries
Annotation:

Currently, the problems of environmental safety are facing society. The industry develops every year. In this critical economic situation, the oil industry is a stimulant for the economic sector in Azerbaijan. The level of development of this industry is also relevant due to other reasons: sociological, technological and features of the economy of Azerbaijan. The production activity of oil processing, concentrating harmful substances and energy, is a source of man-made danger and pollution of the natural environment. The risk management process mainly consists of three stages - risk safety analysis, risk assessment, which is carried out in comparison of calculated and actual risk levels, the so-called acceptable risk levels and the adoption of appropriate regulations and management decisions. One of the factors that should be taken into account when assessing risk and safety is to determine the necessary costs. Since these costs are paid directly to the company, they try to minimize them as much as possible, which reduce the accuracy of risk assessment. One of the objectives of the study is to determine the optimal value of the necessary costs. It is established that the less reliable the method, the lower is the cost of its implementation. The methodological basis of the work was scientific works on these problems of scientists-economists, mathematicians on safety and risk assessment at industrial enterprises. When developing the presented methodology, computational algorithms developed by Dow Chemical were used. This company has collected a large volume of material on accident statistics, taking into account damages. Based on the obtained and experimentally verified data, a system of indices has been developed, an assessment of various indicators for qualitative and quantitative risk assessment of oil refineries. The analysis of the technogenic danger of oil refineries makes it possible to determine ecological and economic losses and choose rational possibilities of acceptable risk. The required costs, depending on the level of risk, are determined based on an increase in the accuracy of calculating the probability of occurrence of the cause of risks. The article examines the relationship between the expected level of risk and economic losses during oil refining in separate technological units, which allow determining the required level of risk and the expected economic damage.
