“…But from such a depth, agronomic practice did not record cases of the emergence of shoots of annual and perennial plants, and if the accidental emergence of shoots of weeds took place especially in fields allotted for pure fallows, then such weeds were destroyed by surface treatment. Secondly, the layered system of the main tillage had a great advantage over the usually used template system of the main tillage on soft, old-arable, heavily vegetated and weedy lands (and there were the majority of such lands), since the unsystematic, template-applied and hastily, mainly in the spring, surface tillage with disc cultivators led to severe clogging of the soil with thistle, milkweed, and especially wild oat, as well as partial dispersal and loss of soil structure [19].…”

This article examines the development of virgin and fallow lands in Kazakhstan in the 1950s. Since the climate in the Kazakh steppes was sharply continental, arid, and the soils unsuitable for farming, the cultivation of grain crops was associated with huge risks and difficulties. Everywhere in those years a great number of state farms were established in Kazakhstan, which had to develop not only vast areas in extraordinary conditions and terms, but also apply innovative for that time and for that area methods of cultivation of high yields of grain crops. Analysis of the materials showed that, despite the difficult natural and climatic conditions, lack of agricultural machinery and labour, the virgin lands cultivators harvested high yields by applying the method of layer-by-layer tillage. The authors concluded that in the course of land use state farm specialists tried to maintain the quality characteristics of the soil.

“…The total concentration of petroleum hydrocarbons in underground waters is four times higher than the World Health Organization (WHO) standards [ 4 ]. An active change in the chemical and physicochemical properties of the soil is ongoing, and the hydrological regime of these terrains is disturbed [ 5 ]. Oil and gas proceedings often lead to heavy metals and other pollutants released into the environment [ 6 ].…”

Most of the country’s oil and gas fields are situated in West Kazakhstan, mainly on the Caspian Sea coast, causing significant damage to the local environment and contributing to an imbalance in the trace element composition of the human body. The study is aimed to evaluate the relationship between the concentration of essential trace elements in scalp hair of the western Kazakhstan adult population and the remoteness of their residence from oil and gas fields. The concentration of essential trace elements (Co, Cu, Fe, I, Mn, Se, Zn) in the hair of 850 individuals aged 18–60 years was determined by inductively coupled plasma mass spectrometry. In residents of settlements located at a distance of >110 km from oil and gas fields, the concentration of Cu and I in hair was significantly higher than in those closer to 110 km (p < 0.001). The content of Cu and I were associated with the distance to oil and gas fields (0.072 (95%CI: 0.050; 0.094)) and (0.121 (95%CI: 0.058; 0.185)), respectively. We detected a significant imbalance in the distribution of some essential trace elements in residents’ scalp hair from the Caspian region of western Kazakhstan, living near oil and gas fields. The concentrations of Cu and I were significantly interrelated with the distance to oil and gas fields. The level of copper in the hair of both inhabitants of the area most remote from oil and gas facilities and the entire population of western Kazakhstan as a whole remains significantly low. The data obtained provide evidence of the possible impact of pollutants generated by the oil and gas facilities on a shortage of essential trace elements and associated subsequent health risks.

The article analyzes the monitoring of hydrogen sulfide content in the air of Atyrau in the winter period of 2021-2022. The purpose of this study is to study the hydrogen sulfide content in the air environment of the city of Atyrau, which has been increasing in recent years as a result of anthropogenic impact. The monitoring results were analyzed according to the data of Kazhydromet observation points, including 15 observation points. Monitoring of the study showed that among 15 observation points, there are exceedances of the maximum permissible concentrations of hydrogen sulfide in all three winter months, but however, it can be observed that the highest concentrations are observed in December and February, whereas in January these data are close to the MPC. Especially high rates are characteristic of points located near the Atyrau Oil Refiner, which is probably the main source of hydrogen sulfide. At the same time, the excess of the MPC for hydrogen sulfide and at points in the territories of the city exceeds more than 5-15 times. An important step towards optimizing the monitoring of the effects of hydrogen sulfide emissions at the Atyrau Refinery is the monitoring of atmospheric air quality and the introduction of modern technologies and dust and gas cleaning equipment. At the same time, it is possible to reduce the emission of hydrogen sulfide as a result of measures aimed at the reconstruction and overhaul of the sewage system in Atyrau.
