HYGIENIC REQUIREMENTS FOR DRINKING WATER

Аннотация

The development of lower norms of mineralization due to the development of brine irrigation technology has become a period requirement, since the constant consumption of distilled or less mineralized water leads to a violation of the water-salt equality in the body, on the basis of which the osmoreceptive field reactions of the liver lie, as a result of which how much sodium is. Keywords. Invasions, poisonings, endemic non-toxic diseases, saprophytic microorganisms. When providing the population with clean drinking water, it should be considered to protect it from various infectious diseases spread through the water and prevent non-infectious poisoning caused by changes in the chemical composition of water, since the impact of water on the human body can be direct, this includes infectious diseases, invasions, poisoning, endemic non-toxic diseases. And the indirect effect is caused by unpleasant sensations when water is consumed, at some point the condition expands so much that even the population refuses to consume water. In other words, the negative effects of water come to the surface under certain conditions, and these conditions include: when there are lambs of infectious diseases in the water, when they differ in the degree of their chemical composition, etc. Violation of the quality and natural condition of the waters can damage human health due to the fact that the water contains a large amount of infectious https://scientific-jl.com/luch/ 2 6 1 Часть-44_ Том-2_ Май-2025 diseases-mosquito microorganisms, or due to an increase in worm eggs or an increase in the content of various chemicals in the water, but rather a decrease in it. The provision of centralized water supply to settlements reduces the incidence rate while improving the sanitary lifestyle of the population. Microbial count is said to be the number of microbial colonies that are detected after 24 hours in a 37 °C thermostat of 1 ml of water planted for examination of meat peptone Agar. The number of germs indicates that the water is contaminated with common germs. Depending on the number of colonies, the quality of the water is determined. In well-equipped artesian wells that are not contaminated, the colony's amount reaches 300-400 in 10-30 uncontaminated mine well water and 100 in vodoprovod water. An important condition for bacteriological assessment of water is the determination of intestinal stick Soin in water. The absence of an intestinal wand in water is expressed by the size of the colititr or coli-index. Colititr it is the minimum amount that a single intestinal wand has in the water. The lower the colititr, the more polluted the water with the litter. Coli index 1 1 the number of intestinal sticks in water. Research studies show that if the coli index is reduced to 3 after water neutralization tif, pathogenic microbes that belong to the paratyphosis group, leptospirosis and tularemia can be said to have disappeared from the causative agents of morbidity. The colitis or coli-index indicators are related to the 1880 discovery of the human organism of the intestinal wand and were introduced into the exercise for insufficient total bacterial contamination of water. Natural water contains biological microlements necessary for the life of humans, animals, various plants. They are involved in important biochemical processes, which are combined with some substances in the activity of living organism. The following trace elements are essential for human health: copper, zinc, iodine, manganese, molybdenum, cobalt, iron and Macroelements: calcium, https://scientific-jl.com/luch/ 2 6 2 Часть-44_ Том-2_ Май-2025 potassium, sodium, phosphorus. These substances fall into the human body with a certain amount of water, food products, satisfying the body's need for these elements. If a person does not meet his needs with the above-mentioned micro and Macroelements, then various diseases can arise in the body. Because the problems of influencing the chemical composition of water on the human body have long been thinking of scientists. It was only at the beginning of the 20th century that for the first time scientifically substantiated opinions on this yainalish appeared. In nature, water never occurs in the form of a pure chemical compound. Since it is considered a Universal solvent, it always stores different amounts of chemical elements in its composition. The amount of chemicals in the aquatic environment depends on the conditions of water formation, while the natural chemical composition of the surface and groundwater is currently also affected by man-made impurities. From the above, it is known that the chemical composition of water: natural, man-made, that is, chemical preservative industry will depend on the wastewater and the human being, as a result of adding reagents to the water in the process of improving the quality of raw water. The overall mineralization of water or the effect of the total amount of salts on the human body is the
