Public environmental monitoring of the state of snowpack in norilsk. [Текст] / N. V. Karmanovskaya, O. V. Nosova, A. V. Kaverzin // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 95-103

Кл.слова (ненормированные):
precipitation -- industrial area -- melt water -- chemical characteristics
Аннотация: It is considered that Norilsk ranks second in terms of atmospheric contamination. Industrial enterprises annually emit large amounts of sulphur dioxide, phenols, and heavy metal particles. The city is located within the Far North and is distinguished by the harsh climate of the subarctic type. The snow cover can lie from 244 to 277 days. Snow is a good sorbent; therefore, the snow cover accumulates solid and gaseous pollutants that enter it from the atmosphere with precipitation or are absorbed from it. The purpose of this study was to analyse the snow cover in the Norilsk industrial region and assess the state of atmospheric air in the winter. To achieve this goal, it is necessary to solve the following tasks: conduct a literature review on a given topic; take samples of snow in various industrial districts of Norilsk; study the dependence of the qualitative characteristics of snow on the sampling site; draw conclusions on the quality of snowpack in different areas of the industrial districts of Norilsk. In the course of the study, the following methods were used: organoleptic, visual, methods for determining water transparency, titrimetric analysis, etc. Heavy metal ions and sulphate ions were not detected in the thawed snow, so no industrial gas pollution was noted in the residential area. Most of the particulate contamination was caused by slagging of roads to improve vehicle traction.

Public environmental monitoring of drinking water quality in the city of Norilsk. [Текст] / N. V. Karmanovskaya // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 104-111

Рубрики: chemical Technology
Кл.слова (ненормированные):
ecological situation -- industrial city -- water supply -- public utilities
Аннотация: According to UN estimates, the shortage of safe drinking water can become one of the most acute and pressing problems. The specificity of this problem for Russia is not a shortage of water resources, but their pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring its condition and properties. During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region, studied the dependence of the quality characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of drinking water were drawn. During the experiment, the authors found that in terms of organoleptic indicators, drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt content is mainly due to the presence of hardness salts. Having made the necessary analyses, the authors found that the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations.

Аннотация: This article discusses the theoretical basis for the destruction of the crystal structure of snow and ice formations from the influence of chemical reagents. They established a natural dependence of the freezing force of snow and ice formations on the impact of various types of salt solutions. Also, laboratory studies have established the effect of the concentration of salt solutions on the loss of strength of cement concrete over time.

Аннотация: The main goal of the study was to develop and test an effective technology for cattle genotyping by the CSN3 gene based on real-time PCR with hybridization-fluorescence detection. There was developed a method for real-time PCR for cattle genotyping by A and B alleles of the CSN3 gene in the format of hybridization-fluorescence detection, involving the use of two 5/-fluorescence-labeled forward allele-specific primers, one reverse common primer, and one anti-primer labeled with a fluorescence quencher at the 3/-end of the oligonucleotide. As a result of practical studies aimed at testing the developed method, we obtained the technical result provided by the proposed technology, expressed in the effective identification of the desired genotypes due to correct interpretation of these curves of increasing fluorescence intensity, the results reliability of which was also confirmed by the well-known PCR-RFLP analysis technique for Bos taurus genotyping for similar allelic variants of the kappa-casein gene.
