This article discusses some of the problems of chemical safety, such as the recycling of waste production, chemical accidents and disasters, environmental pollution and the negative effect of the chemical industry on human health, as well as methods for safer handling of chemical products.

The article describes visually detectable anomalies in the structure of the crucian carpet, which make it possible to consider them as a reliable tool for operative ecological monitoring of aquatic ecosystems under the conditions of the anthropic press. The results of the conducted studies were tested in the course of the research "The Post-Mercury Control of Mercury Pollution in the Territory of the Former PO" Khimprom", and also appear to be important in assessing the environmental risk from groundwater pollution and adjacent water bodies in the northern industrial zone of Pavlodar.

At the present stage of scientific and technological progress and rapid development of industrial production, the problem of environmental protection is becoming a problem. Air pollution has a serious impact on human health, global and regional climatic conditions. The main types of pollutants are gaseous substances. When fuel burns, carbon monoxide is released during traffic. This is a very toxic gas. Blood easily interacts with hemoglobin and continues to function; therefore, it is important to reduce emissions of toxic substances by vehicles and industrial facilities.

The object of the study was water and bottom sediments of the lake Balkyldak of Pavlodar region, contaminated by mercury wastes.The purpose of the work is the creation of innovative cost-effective technologies for deep cleaning of aqueous media from mercury to the level of 1-10 parts per trillion, which will be tested for the cleaning of the lake Bylkyldak facilities in Pavlodar region.

Environmental protection measures are based, among other things, on the rationalization of the organization of the production waste management process. Population growth and the race to industrialize pose a serious threat to the ecosystem. Currently, the average global waste generation per capita is 494 kg / year. A large number of industrial enterprises operate on the territory of Kazakhstan. The range of manufactured products is very wide: household items, transport, building materials, equipment and much more. Each type of production is inevitably a source of a large amount of industrial waste, annually at the enterprises of Kazakhstan up to 600 million tons of waste are generated, three percent of which are recycled. On the territory of Pavlodar region there are enterprises in the field of metallurgy, mechanical engineering, chemical industry, construction industry enterprises, light industry, about a hundred in total. In this connection, the problem of treatment and disposal of industrial waste in Pavlodar region is very relevant. The article discusses the system of waste management in order to reduce their impact on the environment, activities for the disposal, transportation, disposal of waste, as well as their disposal at the industrial waste landfill in Pavlodar. The landfill in question is intended for the reception, temporary storage and disposal of non-hazardous solid industrial waste of the «green» level: waste and scrap of chromium, cadmium, aluminum, copper, lead, zinc, manganese, plastic waste, polyethylene, abrasive, rubber waste, ash and ash and slag waste; and also «amber»: waste containing mercury, arsenic, lead, waste batteries, phosphoric slags, waste oils, oil sludge. The scheme of organizing waste storage works is considered. The volume of accepted and recycled waste, as well as those placed at the landfill and used for their own needs, was analyzed, including construction waste, waste sleepers, ash and slag and abrasive scrap. The solution to the problem of industrial waste disposal is associated with the need for innovation and the introduction of new technologies and equipment.

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.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

Main problem: The article analyzes water quality assurance as the main goal of preserving human health. The study of chemical and microbiological parameters of wastewater and drinking water was carried out using generally accepted standards. The number of deaths associated with the use of contaminated drinking water, according to WHO, tripled in 2021 and reached almost 19 thousand against 6 thousand in 2020. In addition, the number of neoplasms, diseases of the genitourinary system, digestive organs and skin increased by 2 %, to 1.486 million. The reasons for the increase in the level of harmful chemicals and microbiological pollutants in the water are outdated sewage treatment plants, old pipes and disinfection with chlorine. Purpose: Study of the quality of wastewater and drinking water in Pavlodar, study of the quality of wastewater and drinking water in Pavlodar. Methods: Sampling of wastewater, chemical and bacteriological analysis of wastewater and drinking water, statistical method, correlation analysis of experimentally obtained results and calculated characteristics, etc. Results and their significance: In the field of public health risk, pollution of reservoirs that are sources of household drinking water supply and recreational water use, the continuing necessary high deterioration of water supply networks, their accident rate, as a result of low level of operation, failures in the operation of treatment facilities. Hygienic assessment of reservoirs according to complex indicators indicates the continuing high degree of water pollution in places of water use. The water quality indicators of the surface reservoirs of the region remain low in terms of sanitary and chemical (primarily organoleptic and general sanitary), as well as microbiological indicators. According to toxicological indicators, the level of water pollution in places of water use is estimated as moderate. The main pollutants of the Irtysh River in Pavlodar are industrial enterprises and housing and communal facilities that discharge untreated or insufficiently treated wastewater into reservoirs. A complex of causes of drinking water pollution has been identified: high deterioration of water supply networks, their accident rate, because of a low level of operation, failures in the operation of treatment facilities, unfair treatment of industrial wastewater by industrial enterprises of Pavlodar, etc. Priority preventive directions for improving the quality of water as a source of life are the implementation of long-term targeted planning of measures for the modernization of water supply and sewerage networks and facilities in Pavlodar. The state of water supply necessary and measures to improve it should be constantly monitored and considered at meetings of sanitary and anti-epidemic commissions.

On the territory of the Northern industrial zone of Pavlodar in the area of the industrial wastewater reservoir «Bylkyldak» in some areas of the earth there is soil contamination with mercury, exceeding the MPC for mercury (2.1 mg/kg) by 500 times. The total mass of mercury dispersed in the surface layer of soils is 2.8 tons. The mass of contaminated soil is approximately 208,000 tons. Pollution of the territory is historical. The purpose of the article is to determine the efficiency of chemical binding (immobilization) of mercury in the soil with the Japanese drug Denite® in real field conditions of the territory of mercury contamination in the Northern industrial zone of Pavlodar using an experimental study; to determine the stability of insoluble mercury compounds formed by the preparation at extreme winter and summer temperatures and seasonal fluctuations in open ground. Soil samples were taken for the study at 11 points in the centers of mercury pollution. Laboratory studies were carried out in an accredited analytical laboratory of the Testing Center of JSC Caustic. Soil samples were treated with Denite®, the preparations obtained were stabilized, and water extracts were prepared. The content of mercury in soils, extracts from them, and plants was determined by the atomic absorption method on a RA-915+ spectrometer equipped with RP-91 and RP-91S attachments. As a result of research, the effectiveness of Denite® in the chemical binding of mercury in the soil has been proven and its optimal dosages have been determined. As a result of the positive tests of the technology of chemical immobilization of mercury, the prospect of a practical solution to the issue of demercurization of mercury-contaminated soil on the territory of the Northern industrial zone appeared.

The relevance of this article is that the impact of human economic activity on the natural environment is becoming comparable in scale to geological factors. In this regard, the importance of protecting the biosphere has increased immeasurably. The earth is the only common home of all earthlings. Society, including us, cannot help but worry that the planet has approached a critical ecological threshold. The main goal of the research that we set for ourselves in this article is to create a predictive model for overcoming the environmental crisis in the following areas: environmental education, greening technologies, administrative and legal direction, international cooperation. To achieve the result, we tried to process as much information as possible, analyze the situation, draw appropriate conclusions and propose our own model for overcoming the environmental crisis. The hypothesis is that environmental pollution, improper disposal of household and industrial waste, and poor environmental culture have a detrimental effect on the ecology of the city, poisoning the environment and public health. The main research methods used were methods of empirical knowledge - these are observations, survey methods, questionnaires, as well as theoretical methods. The results of these studies can be used to inform the population about the impact of waste on human health, as well as the importance of storing, recycling and obtaining secondary raw materials, in order to reduce the amount of garbage on city streets. And also about the existence of unauthorized waste collection sites and administrative responsibility for the creation of such landfills in the city and in the surrounding area, this is an educational activity in all areas of education, starting from preschool institutions, the media, advertising agencies, NGOs, environmental authorities and also, using international experience, in the construction of a solid waste processing plant in his hometown.
