“…It is well known today that these compounds often have a pronounced toxic effect on the human body, and the quality of drinking water affects human health. Continuous use of water with high nitrate content can lead to various diseases, including methemoglobinemia in children, especially those under 3 years of age (Lototska et al, 2019, Mokienko et al, 2017.…”

The problems of drinking water quality have been considered in some settlements of the Turkivskiy district of Lviv region, in particular concerning the content of Nitrogen compounds. 20 sources of decentralized water supply were investigated. It was found that the main hydrochemical indicators of water samples mainly met the requirements for the degree of contamination of hygienic classification of water bodies. At the same time, analyzing the samples for the presence of nitrogen compounds, it was found that in the tested samples: the content of nitrate ions fluctuated within 0,02 - 016 mg/dm3 (average annual values did not exceed the permissible value); the content of ammonium ions is in the range of 0.5-2.8 mg/dm3, which did not significantly exceed the maximum permissible value. At the time, analysis for NO3- showed an excess of acceptable values in almost all samples by 1.3 у 4.2 times. It was found that the amount of nitrates decreased with the transition from the alluvial aquifers to the indigenous ones, where the average content was 108.9 mg/dm3 and 86.8 mg/dm3, respectively. This is probably due to better protection of the bedrock from surface contamination, greater capacity of the corresponding aquifers and their deeper occurrence. According to the average value of the water pollution index for the nitrate group, the studied objects of decentralized water supply belong to the second class ‒ moderately contaminated. The correlation between the water pollution index by nitrate group and the population morbidity is calculated to be direct and sufficiently high (0.73). The most associated indicators of water quality are diseases of the circulatory system, blood and hematopoietic organs, digestive organs, endocrine and urogenital systems.

Вступ. З питною водою в організм людини надходить багато різних хімічних речовин. Є такі, які в понаднормативній кількості можуть негативно вплинути на організм споживачів. До таких речовин належать нітрати або солі азотної кислоти, які надзвичайно поширені у навколишньому середовищі. Крім нітратів, найбільш пріоритетними хімічними сполуками, які визначаються у підземній воді в кількості, що перевищує нормативи, є солі жорсткості. Мета дослідження – вивчити вплив питної води з нормативним і понаднормативним вмістом нітратів та солей жорсткості в комбінації на рівні 1, 3, 5 і 10 ГДК на білковий обмін в організмі піддослідних тварин за умов підгострого експерименту. Методи дослідження. Експеримент проводили на 30 білих щурах-самицях, поділених на 5 груп, які відрізнялися між собою за якістю питної води. Тварини контрольної групи споживали воду з міського водогону, щури 1-ї групи – воду з вмістом кальцію та магнію в поєднанні з нітратами на рівні 1 ГДК, 2-ї групи – 3 ГДК, 3-ї групи – 5 ГДК, 4-ї групи – 10 ГДК. Для оцінки білкового обміну в сироватці крові піддослідних тварин визначали рівень загального білка, креатиніну, сечовини й активність аспартат- та аланінамінотрансфераз. Результати й обговорення. У результаті споживання тваринами протягом 30 днів питної води з нормативним і понаднормативним вмістом нітратів та солей жорсткості виявлено зміни рівня окремих біохімічних показників білкового обміну, а саме зростання вмісту загального білка, креатиніну й активності трансаміназ та зменшення кількості сечовини. Зміни були найбільш виражені у тварин 4-ї групи (р<0,05). Висновок. За умови тривалого споживання такої питної води можна очікувати, що встановлені зміни призведуть до розвитку патологічних процесів та виникнення захворювань в організмі тварин і людей.

“…Due to insufficient purification and disinfection, water can lead to bacterial, viral and parasitic diseases such as cholera, shigellosis, typhoid fever, paratyphoid fever, hepatitis, gastroenteritis, amoebic dysentery, giardiasis, etc. [7]. Lack of potable water in sufficient quantities can provoke dehydration.…”

The purpose of the research was to scientifically substantiate the conceptual approaches to the development of normative document on drinking water quality in order to prevent morbidity and mortality in martial law during armed aggression in Ukraine and other emergencies. Materials and methods: descriptive, sanitary-chemical, normative-search, comparative analysis, expert assessments have been used. The paper analyzes the results of observations of efficiency and monitoring of water quality from water supply stations of Ukraine before and after the war, and compare assessment of the main provisions of regulations on drinking water quality of some countries, including those used in emergencies. Results. The research established that in wartime centralized drinking water supply companies are burdened by problems due to unguaranteed quality of source water, lack of stable conditions for the technological process of water treatment, operation or destruction of water treatment plants and networks etc. Current standards in Ukraine( DSanPiN 2.2.4-171-10 "Hygienic requirements for drinking water intended for human consumption") during martial law require significant changes: supplementation of safety and quality indicators due to the new risks of drinking water pollution; exclusion of certain safety and quality indicators at the expense of non-priority ones; establishment of temporary hygienic standards for tap water and water dispensing points and the procedure for their use; adjusting the frequency of production control of potable water; implementation preventive measures to reduce morbidity and mortality. Today the project of “DSanPiN "Safety indicators and some particular indicators of potable water quality during martial law and emergencies of another nature" (hereinafter - DSanPiN) has been scientifically substantiated and developed. According to the draft of this document, the quality of drinking water in terms of epidemic and radiation safety must meet the requirements of DSanPiN 2.2.4-171; in terms of physicochemical - see requirements of DSanPiN. The requirements of DSanPiN after their state registration will be applied during martial law and during emergencies of other nature in a particular area for a specified period as short as possible by the relevant regional or local commission for technogeneous environmental safety and emergencies. Conclusions. It is established that during the military emergency situation in Ukraine the current DSanPiN 2.2.4-171-10 "Hygienic requirements for potable water intended for human consumption" require significant changes in order to: supplement safety indicators due to the emergence of new risks of drinking water pollution; exclude certain indicators of safety and quality due to non-priority; establish temporary hygienic standards for potable tap water and bottling points in personal containers of consumers and the procedure for their use; adjust the frequency of production control of potable water quality; implement other preventive measures to reduce morbidity and mortality.. Nowadays the draft DSanPiN "Safety indicators and some indicators of potable water quality in martial law and emergencies of other nature" is scientifically substantiated and developed, and it was submitted to the Ministry of Justice of Ukraine for state registration.
