This article discusses the possibility and practice of Kazakhstani enterprises producing chemical products and raw materials, which are oriented to export regulations REACH, adopted by the European Union that will greatly increase the safety and competitiveness of domestic production.

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 presents a study of the effect of a resistor in a network neutral point from 6 to 35 kV on the conductive electromagnetic interference with the ground-fault current. A mathematical model is proposed.

Main problem: The genus Morbillivirus of the family Paramyxoviridae includes agents of morbilli, plague of cattle, carnivores and small ruminants. Plague agent of carnivores causes a dangerous disease of fur animals and dogs, which in many cases ends in death. The disease is widespread everywhere, including Kazakhstan. In our country, the mixed form of the disease is most common, and the least common is the skin and nervous forms. The chronic course of plague is observed to a greater extent with the nervous form, subacute - with mixed and intestinal, acute - with cutaneous and pulmonary forms of the disease. Goal: Veterinarians have significant difficulties in diagnosing carnivorous plague. Despite the fact that serological methods for diagnosing this infection have been developed and applied for research purposes, the lack of commercial diagnostic preparations on sale significantly restrains their use by practical veterinary workers. Therefore, the diagnosis of plague of carnivores is mainly established on the basis of the symptom complex of the disease and the data of epizootic and pathological anatomical studies, the results of which are largely similar to those in some other diseases of carnivores. Scientific research in the field of means and methods of laboratory diagnostics of carnivore plague, applicable in practical veterinary medicine, is in great demand. Methods: Considering the fact that the carnivores plague and cattle plague are antigenically closely related, studies were carried out to determine the possibility of using means and methods for diagnosing cattle plague for serological diagnosis of carnivores plague. Results and their significance: It has been established that the use of means and methods for diagnosing cattle plague makes it possible to diagnose carnivore plague at all stages of the course of the disease, their use makes it possible to reliably establish a diagnosis of the disease in fur-bearing animals and dogs in a short time after the receipt of samples of material for research, even in cases of mixed viral and bacterial infections; and also to differentiate the plague of carnivores from diseases similar to it - parvovirus enteritis, infectious hepatitis and a number of others.

Main problem: At present, service, decorative and hunting dog breeding is intensively developing in Russia and in the Tula region. So, in 2020, 119 high-breed puppies were registered in the Book of Pedigree Breeding, and in 2021 already 164 puppies, mostly decorative and service breeds. Thus, the number of pedigreed dogs susceptible to various infectious diseases is increasing annually. Canine distemper is one of the most widespread viral diseases of dogs all over the world, including in Russia. Analyzing the "Patient Admission Logs" of veterinary clinics in the city of Tula, it was found that 44 % of dogs that fell ill with diseases of infectious etiology were diagnosed with canine distemper. Purpose: The aim of our research was to study the epizootological features of the course of canine distemper among dogs in the Tula region of Russia. To achieve the intended goal, it was necessary to solve the following problem: to analyze the breed and age factors for the incidence of canine distemper. Methods: Analysis of data from private veterinary clinics reporting on the incidence of small domestic animals was used. Results and their significance: As a result of studying the epizootic situation of canine distemper among dogs, the following data were obtained: The disease is observed throughout the year and has the character of undamped fluctuations subject to sharp seasonal changes. The maximum number of diseased dogs in all years of observation is recorded in March - 6.2 cases per 1000 individuals. It has been established that among the infectious diseases of dogs, distemper occupies the first place, and there is an annual increase in the number of dogs with distemper.
