We have analized available literature on the capability of micro- scopic fungi (micromycetes) to exist and reproduce in the water (i.e. tap water) that is provided to consumers. The following mi- cromycetes, most typically present in tap water, were identified, namely: Aspergillus, Fusarium, Penicillium, Alternaria, Clad- osporium and Candida. The average number of micromycetes ranges from 8 to 18 CFU/100 cm3 , with yeast fungi dominantly present. Toxic substances (mycotoxins) that produce microscop- ic fungi are described, as well as their effects on the human body. It is noted that most mycotoxins stimulate formation of excessive free radicals and oxidative stress, which leads to impaired func- tion of the body’s antioxidant system, namely the production of a prooxidant enzyme in liver cells, immune organs and in the gastrointestinal tract. Therefore, , the presence of processes of apoptosis that lead to little sorption syndrome, immunosuppres- sion. The potential water routes of mycotoxins into the human body have been identified. The ability of mycotoxins, which form micromycetes – most often found in tap water, to cause cancer, have been analyzed in detail, using available literature on the subject. Mainly the effect of aflatoxins, trichothecenes, ochratox- ins and gliotoxins was examined. The presence of microscopic fungi in water supplied to the consumer, as well as their ability to form toxins necessitates systematic studies of water samples for the detection of micromycetes and the toxins present in it. And, finally, an important avenue for further research is outlined, which is to develop a simple and affordable method for the de- tection of mycotoxins in the water, based on the use of a sensitive test objects.

Introduction. Drinking water is a necessary element of life support of the population. Many studies conducted around the world have established a relationship between the quality of drinking water and public health. On the basis of the Perm State Medical University studies were conducted to assess the effects of oxygen-enriched drinking water on human respiratory, cardiovascular and nervous systems as well as serum erythropoietin (EPO) levels. The objects of study were 32 volunteers (7 men and 25 women) aged 18 to 28. The purpose of the research was to study the effect of oxygen-enriched drinking water on the basic physiological systems of the human body and serum EPO levels of healthy volunteers. Methods. We applied the following research methods: physiological methods were used thrice (on the first, tenth and twenty-first days) to test the cardiovascular (heart rate, SBP, DBP, Kerdo index, Harvard step test), respiratory (BH, JELL, JEL, Stange and Gencha tests) and nervous (Anfimov test, SAN test, ShAS test) systems; laboratory tests of serum EPO levels in venous blood of the volunteers; and statistical methods (statistical processing was performed using Microsoft Office Excel 2007 and STATISTICA V. 7 software package (StatSoft Inc., USA). Results. The use of oxygenated water helps increase functional and reserve capabilities of the basic physiological systems of the body and improve tissue oxygenation.

Certain essential and conditionally essential natural elements (selenium, chromium, iodine, molybdenum, cobalt, vanadium, fluorine, lithium, silicon, boron, and bromine) are standardized in terms of their contents in drinking water as per sanitary-toxicological parameters of adverse health effects. Our research goal was to determine a contribution made by drinking water into supplying a human body with essential natural elements as well as to substantiate the necessity to update standards regarding these substances. We applied calculation models for dose equivalents of essential elements MPC (maximum permissible concentration), MPC calculations for these substances basing on a necessary 20 % contribution made by drinking water into reference doses, and calculation of non-carcinogenic health risks due to essential elements occurrence in specific drinking water sources with these elements being distributed into different groups as per similar effects produced on certain organs and systems in a body. We took existing drinking water sources containing 6 essential elements with similar effects as an example and applied a procedure for assessing non-carcinogenic health risks. Acting nickel and selenium MPC do not supply a body with an optimal daily intake whereas their determined MPC are not only harmless but also conform to the minimum necessary intake dose. At the same time neither acting lithium MPC nor its calculated one taking into account risk assessment based on internationally accepted reference doses doesn’t provide the minimum necessary daily intake into a human body. When boron and vanadium are contained in drinking water in a concentration close to their MPC, then their 20 % contribution into the reference dose is exceeded (71.4 % and 164.7 % accordingly). Introduction of these essential elements with food can become a factor that determines non-carcinogenic risk level.

Processing water products sources into ready-to-drink water have been widely circulated in community, one of it's a household drinking water filter with 4 filter stages. Drinking water itself is indispensable for human body. It's because most of the human body is made up of water. To meet the water needs in human body, drinking water is required. Drinking water that consumed by community must meet drinking water standards that have been determined by Minister of Health Decree No. 492/2010, which must meet physical, chemical, biological and radioactive requirements.This research aimed at monitoring several drinking water quality parameters in form of Ph (6.5 - 8.5), Turbidity (<5 NTU) and temperature (22 ? - 27 ?) by using pH sensor, turbidity sensor and temperature sensor, and ON/OFF scheduling of ultraviolet light as an inhibitor of bacterial growth which then monitoring results will be sent via nodeMCU ESP8266 and displayed on WEB. The results of the Ph sensor readings show a reading accuracy of up to 97.28%, on the temperature sensor the reading accuracy reaches 98.7%, while the turbidity sensor has an accuracy level of up to 98.875%, the ON/OFF of UV light goes according to schedule. The application software used able to read and store data in real time from water quality sensor so users can monitor quality of drinking water. Water from filtration of water filter can be categorized as suitable for drinking in accordance with drinking water standard in the Decree of Minister of Health No. 492 in 2010.

Sem a água o corpo humano não sobrevive. Não apenas a espécie humana, mas todos os seres vivos necessitam de água para o funcionamento do seu organismo, seja ele animal ou vegetal. À vista disso, e considerando a problemática atual da escassez de água no país e o recente reconhecimento pela ONU do direito à água potável como um direito humano, fica evidente a urgência na busca por meios de preservação deste elemento indispensável para a manutenção da vida. A tributação com finalidade extrafiscal do fornecimento de água potável é uma dentre as opções de ações governamentais que poderia ser utilizada com objetivo de salvaguardar bem tão precioso. Entretanto, indispensável uma análise mais aprofundada sobre as espécies de tributos possíveis para cumprir esta função, principalmente no que tange às suas vantagens e desvantagens, razão pela qual o presente estudo se demonstra necessário.Palavras-chave: Água. Tributação. Extrafiscalidade. Direitos fundamentais. Sustentabilidade.Abstract: Without water the human body does not survive. It is not just the human species, but all living things need water, animal or vegetable. Having that in mind, and considering the current problem of water scarcity in the country and the recent recognition by the UN of the human right to water and sanitation, it is evident the urgency in the search for ways to preserve this element that is indispensable for maintaining life. The extra-fiscal taxation of the supply of drinking water is one of the many options for governmental actions that could be used with the purpose of safeguarding so precious good. However, a more in-depth analysis of the possible tributary types to fulfill this function is essential, especially as regards their advantages and disadvantages. Keywords: Water. Taxation.

In recent years, as a result of intense anthropogenic impact, the composition of groundwater has changed markedly. Despite the relatively high protection of groundwater from pollution, the content of pollutants is detected in significant quantities. One of the priority groups of chemical pollution is heavy metals, which belong to an important group of environmental pollutants. Depending on the forms of being in the water, they differ in their chemical and biological activity. Currently, determining the quality of groundwater, identification of trace elements is a topical issue. This article presents the results of research on the content of trace elements in groundwater. Analysis of the content of heavy metals in the wells of Kyiv region during 2020 shows that a significant excess of water pollution by heavy metals is not observed. Taking into account the current MPC, a small excess of iron and zinc content was noted in Volodarskyi district. Heavy metals are known to have mutagenic, toxic effects and affect the intensity of biochemical processes. But the toxicity of trace elements is determined not by their total concentration in water, but by the forms of finding. Therefore, the presence of VM in drinking water samples is highly undesirable, as there will be a constant supply of chronic doses to the human body. As a result, it became necessary to calculate the total pollution of heavy metals, groundwater samples in Kyiv region. In addition, the ecological state of the environment is directly related to changes in the internal human environment. It is the deficiency or excess of certain microelements in drinking water or non-observance of its stable chemical composition in certain areas that from time to time outbreaks of diseases, the cause of which is difficult to establish. Heavy metals that can be found in drinking water are very harmful to human health. The most dangerous Cd, Pb, because on the one hand their man-made accumulation in the environment is quite high, and on the other — these elements have a significant affinity for physiologically important organic compounds and can inhibit the most important metabolic processes, inhibit growth and development. Their long-term effects on the human body can lead to the development of cancer, damage to organs, the nervous system, and in extreme cases, to death, as noted in the publication.
