Having access to a safe water supply is important to improve a person's quality of life. We examine the relationship between the influence of water availability on monthly household expenditures (the dependent variable) and independent variables such as household characteristics, tank size, usage instructions and post-construction guidance, including the management of water-related health risks. The sample consisted of 301 respondents who harvest rainwater in Uganda. A multiple regression analysis was used to analyse the data. The findings show that post-construction guidance and tank size were significant variables. This study suggests the need for a follow-up to improve health after the installation of water supply equipment, i.e., to provide information about water risks, foster reading norms and facilitate the availability and affordability of information sources, e.g., subsidised newspapers and information support devices (computers). Additionally, this study shows the possibility of increased savings due to reduced expenditures on water from vendors and the management of water-related health risks caused by a water shortage, e.g., dehydration. Overall, the study reveals two possible ways to advance policy and health in developing countries: (1) ensuring sufficient post-construction guidance for all water resources; and (2) ensuring a sustainable supply of adequate safe water in households.

Environmental contamination is still a pressing issue, in particular, contaminated drinking water sources and contaminated drinking water from centralized communal water supply systems, since it produces negative effects on human health. Our research goal was to estimate probable impacts exerted on overall morbidity in Samara by quality of drinking water taken from centralized communal water supply systems as a most significant environmental factor. Our research tasks included taking and analyzing drinking water samples from centralized communal water supply systems; calculating carcinogenic and non-carcinogenic health risks caused by analyzed chemicals. To fulfill the tasks and achieve the goals, in 2018–2019 we performed sanitary-chemical analysis of drinking water quality as per 20 sanitary-chemical parameters; our research object was drinking water taken from centralized communal water supply systems in 7 districts in Samara. Obtained actual data on contamination of water taken from centralized water supply networks in Samara were used as primary basis for calculating hazard indexes and carcinogenic risk coefficients using conventional exposure scenarios. In our research we revealed that maximum total non-carcinogenic hazard quotient was determined by arsenic and petroleum products introduction. Assessment of carcinogenic risks caused by contaminants in drinking water revealed that total health risk for children younger than 18 was within the second range as per its median; total carcinogenic risks for adults, within the third range. At the same time, arsenic contents did not exceed hygienic standards in all examined samples. So, we assessed carcinogenic and non-carcinogenic risks, basing on actual data on quality of drinking water taken from centralized communal water supply systems. It seems vital to perform a wider-scale controlled study in several regions in order to assess significance of revealed factors for morbidity among population.

The object of the study was the centralized drinking water supply system of the Voronezh Region. The purpose of the study was to assess health risks for the population of the Voronezh Region associated with drinking water quality. Materials and methods: The data of the regional drinking water quality monitoring system, which included monthly sampling and testing of water samples at 553 sites in 32 administrative districts and the city of Voronezh for 8 priority sanitary and chemical indicators (total hardness, concentrations of iron, manganese, nitrates, nitrites, boron, fluorine, and ammonium ions) for the years 2010-2019 were used. To achieve the objective based on monitoring studies of drinking water quality in the water distribution system, four generally accepted stages of risk assessment were implemented including hazard identification, evaluation of dose-response relationship, exposure assessment, risk quantification and characterization. When evaluating the exposure, four calculation scenarios were considered and probable body burdens for children and adults were calculated using the average long-term concentration and 95 percentile of concentration in a separate administrative territory. Results: Regional non-carcinogenic risks estimated on the basis of the average regional concentrations of priority pollutants did not exceed acceptable values (HQ < 1) for 6 of 7 ingredients. Unacceptable risk levels were observed in two of 33 administrative districts due to the presence of nitrates in drinking water (HQ ranged 1.34 to 2.95 for children and equaled 1.26 for adults). Detailed information for separate settlements (control points) using an aggravated scenario helped identify 4 rural settlements in 2 administrative districts with unacceptable risks for the child population of iron in drinking water (HQ up to 2.31), 230 settlements in 27 districts – of nitrates (HQ up to 9.51), one settlement – of boron (HQ = 1.17), and 35 settlements in 13 districts – of fluorine (HQ up to 4.17). Discussion: Summarizing the results of the regional studies of health risks for the population associated with the quality of drinking water, one can testify the shift of the problem to rural settlements where water treatment is practically null. The use of average concentrations of chemicals in drinking water in administrative districts proved to be insufficiently objective and having significant uncertainties. The reduction of uncertainties was achieved by a detailed review of the information for each monitoring site and the use of the 95th percentile concentration of the chemical to assess the health risks for children and adults. Conclusions: With a sufficient degree of certainty, the priority regional indicators determining the unacceptable level of non-carcinogenic risk (HQ > 1) associated with the quality of drinking water include elevated levels of nitrates, fluorine, boron, and iron. Key words: drinking water, centralized water supply, water quality, public health risk.

Environmental Health Literacy

This article discusses the development of a model of environmental health literacy to maintain a sustainable ecosystem on peatlands. In maintaining the sustainable peatland ecosystem, an environmental health literacy model is needed so that the community can follow up on the health of the surrounding environment. To make informed decisions, communities must have the ability to obtain, process and understand health and environmental information. The approaches used in environmental health literacy are 1 - basic, and functional literacy with efforts to evaluate environmental health information, 2 - communicative interactive and awareness literacy in reducing health and environmental risks and 3 - improving quality of life and protecting the environment with provide education so as to change people's behavior. Ultimately, efforts to develop this model of environmental health literacy are intended to prevent the occurrence of peatland ecosystem damage and can empower communities through an increased understanding of health risks and environmental risks that affect health and the environment.

Solids Content

Good water supply practice provides benefits such as water and energy conservation but also alters the quality of yield. These effects of irrigation on yield quantity and quality are widely researched in the case of many plants. In tomato it can affect the soluble solids content positively together with a slight reduction in yield quantity as confirmed by many studies. There are results in the literature regarding its effect on carotenoid composition and lycopene content as well, but the effect on lycopene isomers has not been revealed yet. In this study, we investigated how different water supply levels affect yield quantity and quality, focusing on lycopene components. A two-year open field irrigation experiment with a center pivot capable of variable rate irrigation was conducted on processing tomato. The water supply levels were 100%, 75%, and 50% of ETc (crop evapotranspiration) until the beginning of the ripening stage, calculated by AquaCrop compared to control without regular irrigation. The results suggested that 75% of ETc supplied till the beginning of ripening, was a balanced water supply level regarding yield quantity, soluble solids content and lycopene concentration and yields, such as higher concentration and ratio to total carotenoids. The evaluation of cis-lycopene concentration and ratio to all-trans did not show clear results in the two years.
