Special Role

Introduction. The proposed criteria for the sanitary-bacteriological assessment of the quality of tap water must ensure its epidemic safety. In conditions of intensive bacterial contamination of water bodies, a special role is played by the barrier function of water treatment plants in relation to infectious agents. The overall quality of microorganisms is the pronounced resistance in the aquatic environment, primarily resistance to a number of chlorine-containing disinfectants, which guarantee the preservation of the population in drinking water undergone a water treatment system. Therefore, it is necessary to consider other possible ways of disinfection, such as ultraviolet irradiation. Determination of the effective dose of ultraviolet (UV) disinfection against bacterial, viral and parasitic contamination of drinking water. Material and methods. Tap water was used as model water for research. The effectiveness of UV irradiation with doses of 25, 40, 60 mJ / cm2 against microorganisms was studied. Results. In the course of the work, it was established that the UV disinfection technology with a dose of at least 25 mJ/cm2 can be recommended as a disinfection method when used in conjunction with chlorination. Conclusion. In water treatment technology, a dose of at least 25 mJ/cm2 of UV irradiation can be recommended as a method of disinfecting water in case of microbial contamination by bacteria and viruses at a concentration not exceeding nˑ102 cells/virions in 100 ml, and at a concentration of microbiological contamination nˑ103 cells/virions in 100 ml of water, the use of UV disinfection can be recommended only in conjunction with chlorination and with the provision of indices on the residual chlorine in the distribution network before serving to the consumer. The presented scheme will increase the barrier role of water treatment facilities with respect to viral and bacterial contamination, provide a prolonged decontamination effect, contributing to the suppression of bacterial growth in breeding nets and limit the level of parasitic water contamination during water treatment.

The Difference

This study is intended to find the quality of bottled drinking water (AMDK) and drinking water (AMIU) sold around University of Muhammadiyah Kudus, in terms of organoleptic and microbiological parameters in drinking water according to SNI 01-3554-2006 and PMK No. 492 of  2010. The test is carried out using 10 sample of drinking water. They are 7 sample of AMDK (Ades, Airmu, Aqua, Cleo, Crystalin, Le mineral and Vit) and 3 sample of AMIU (Pasuruhan, Prambatan and Purwosari depots). The research consists of organoleptic and  mikrobiologi (TPC, presence of E. coli and total coliform). The results of research shows that the organoleptik of all samples is in normal condition. Whereas, microbiologically, the TPC results before dilution were only Cleo and Ades which were suitable for consumption because they were absent from bacterial contamination. While the TPC results after dilution, testing the difference between E. Coli and Total coliform resulted in 7 samples of bottled drinking water which were safe and feasible as drinking water according to SNI 01-3553-2006 and 3 samples AMIU does not fulfil PMK No. 492/2010, as drinking water requirements.

У статті проведений аналіз формування складуводи, що використовується для напування тварин угосподарствах південної біогеохімічної зони України.Представлено санітарно-гігієнічну оцінку джерелводопостачання; досліджено санітарно-гігієнічніпоказники безпечності та якості питної води. Вста-новлено, що зони санітарної охорони біля водозаборіву господарствах відсутні, порушуються також са-нітарно-гігієнічні вимоги, що й сприяло бактеріаль-ному забрудненню підземних вод. Вивчено, що за хімі-чним складом досліджувана вода є прісною, з підви-щеною мінералізацією гідрокарбонатного класу групинатрію та кальцію другого типу. На основі резуль-татів досліджень виявлено, що вміст меркурію і мангануперевищував гранично допустимі концентрації. The article analyzes the formation of water, which is used for watering animals on the farms of the southern biogeochemical zone of Ukraine. It is given the sanitary and hygienic estimation of water sources. There were investigated sanitary and hygienic safety and quality of drinking water. There was found that the sanitary protection zones on the farm near water intake were absent. The authors believe that this may promote bacterial contamination of underground water. There was established that as to the chemical composition of fresh water it had increased mineralization due to bicarbonate and sodium content and may be classified as the second type. There was also found that mercury and manganese content exceeds the maximum permissible concentration.

School Food Environment

This paper examines the changes to procurement for school food environments in Canada as a response to changes to nutrition regulations at the provincial level. Interviews with those working in school food environments across Canada revealed how changes to the nutrition requirements of foods and beverages sold in schools presented opportunities to not only improve the nutrient content of the items made available in school food environments, but also to include local producers and/or school gardens in procuring for the school food environment. At the same time, some schools struggle to procure nutritionally compliant foods due to increased costs associated with transporting produce to rural, remote, or northern communities as well as logistic difficulties like spoilage. Although the nutrition regulations have facilitated improvements to food environments in some schools, others require more support to improve the overall nutritional quality of the foods and beverages available to students at school.

The relevance of the chosen topic is closely related to the development of a system for monitoring the implementation of the May Presidential Decree (2018) to increase life expectancy and improve the quality of life of the population. It has been stated that despite the positive dynamics of life expectancy over the past decade, Russia still has a huge regional differentiation (16,6 years for women, 18,2 years for men in 2016) and an average gender gap - 10,6 years. The choice of factors affecting the gender gap in life expectancy in Russian regions is supported by a conclusion most common in foreign studies that climatic conditions, living conditions, the quality of food and drinking water, alcohol consumption are essential components of public health and life expectancy.The article provides an overview of studies on assessment factors of life expectancy, presents the authors’ approach to identifying gender gaps in life expectancy, living conditions, and lifestyle affecting the indicator of life expectancy. The paper presents the results of a comparative analysis of gender gap in life expectancy in Russia and foreign countries. The paper studies the correlation between living conditions and lifestyle, and life expectancy.Classification of the regions by the life expectancy at birth for men and women is an important component of this study. The authors used Rosstat data for 2016 and the k-means method to select three clusters of Russian regions taking into account gender, living conditions and lifestyle. The paper identifies similar health problems of the regions that are associated with alcohol consumption, poor nutrition and poor quality of drinking water, poor housing and living conditions. The lowest life expectancy rates for men and women are recorded in regions of the 1st cluster (Jewish Autonomous Region, Republic of Tuva, Chukotka Autonomous Area). High mortality rates are a result of external causes. There is a poor quality of drinking water and poor nutrition, excessive alcohol consumption, and inadequate housing conditions.Based on the obtained results were determined possible reserves for reducing the gender and regional differentiation of life expectancy.
