Content and Distribution of Radionuclides in the Profile of Light Gray Forest Soil and Agrocenosis Plants

The results of long-term radiation monitoring of light gray forest soil and cultivated plants of the reference area are presented. Correlation analysis has determined the relationship between the distribution of artificial and natural radionuclides in the soil profile with its agrochemical properties. The distribution of radionuclides in the soil profile is determined by the intensity of the podzolic process. The profile shows the eluvial-illuvial differentiation of radionuclides, when an increase in their accumulation occurred in the illuvial horizon. According to the density of contamination of the surface soil layer with cesium-137 and strontium-90, a satisfactory level of the environmental situation was determined, according to which the soil of the site is classified as uncontaminated. Rows of cultivated plants with an increasing ability to accumulate caesium-137 and strontium-90 from the soil have been constructed. The grain of all grain crops accumulated less cesium-137 and strontium-90 compared to straw. All grown plant products of all types of crops fully met veterinary and hygienic standards for the content of caesium-137 and strontium-90 in feed (green mass, straw and feed grain) and food grains. The coefficients of accumulation and transfer of caesium-137 and strontium-90 from soil to plants were calculated.

Assessment of Sanitation Services and Practices among Local Community in West B Municipality in Zanzibar Island, United Republic of Tanzania

Good basic sanitation services and practices are essential in maintaining generally accepted standards for personal hygiene and public health. The objective of this paper is to assess the sanitation services and practices among the local community in West B Municipality in Zanzibar Island, United Republic of Tanzania. The study uses a cross-sectional study design. Raosoft online sample calculator was used to determine the sample size while systematic random sampling was applied to select the respondents. Results show that a substantial proportion of the community uses on-site sanitation systems by which excreta and wastewater are collected and stored in containments within the vicinity, requiring emptying when full. Many toilets have security issues as they lack privacy and user comfort. About 28.8% have unlockable doors, 21.2% have fixed clothing curtains and 3.8% are completely open. In the area, Indian-type squat toilets are dominant (78.75%), followed by traditional pit latrines (20%). A slightly large percentage (55%) of households use motorised but the remaining percentage (45%) use non-motorised means of emptying and transportation. The study further found limited or ineffectual use of Personal Protective Equipment (PPE) among the sludge workers, thus risking their health and safety. The conveyed sludge waste is usually taken to a designated treatment plant, disposed of in excavated pits or dumped openly in the forest. This implies that sanitation services and practices in West B are inadequate, leading to disease transmission due to environmental pollution. The study recommends compliance with standards and guidelines, awareness and advocacy, technological innovations, stakeholder involvement and research and development on sanitation services and practices.

Strengthening Community Healthy Behavior to Support Tourism Area

Kenjeran Beach Amusement Park is one of the beaches with a strategic area bordering the Madura Strait. In addition, Kenjeran Beach Amusement Park also provides several facilities that can be enjoyed by tourists. The results of observations, still found low personal hygiene of food vendors, not all food vendors provide trash bins, and tourists are still seen littering. Based on the results of the problem situation analysis, it is necessary to strengthen healthy behavior in the community around the tourist area. The targets of the activity were elementary school students around the Kenjeran beach tourism area in Surabaya City 113 students and food and beverage vendors in the Kenjeran beach tourism area 20 in number, using total sampling. The purpose of community service activities carried out to strengthen community healthy living behavior to support tourism areas in the Kenjeran Beach area, Surabaya. The implementation that has been carried out in this community service are education to elementary school children, education to food vendors, observation of the cleanliness of the tourist area observation of how to serve snacks and laboratory tests of microbial contamination in food/beverage snacks. Then to evaluate understanding after education by analyzing the mean value of pre-test and post-test. The results of this activity have provided education for elementary school students regarding clean and healthy living behavior in the area even though the average pre-test score of 6.15 decreased to 6.07 during the post-test. The socialization of safe and healthy snacks for food vendors in THP Kenjeran Lama has also been carried out with the pre-test score having an average of 5.2 then increased to 8.7 at the time of the post-test. Laboratory test results showed a very alarming condition, namely 88.89% of food-beverage samples were contaminated with microbes with various types of bacteria. Suggestions from the results of this activity are still the need for more intensive education to school children about the selection of snacks and diseases transmitted through food and beverages. There is still a need for assistance from food vendors in processing and serving food and drinks by sanitary hygiene standards.

Качество атмосферного воздуха и риск развития болезней системы кровообращения у населения крупного города европейского севера

Cardiovascular diseases are the most frequent causes of premature mortality associated with ambient air quality. In the Arkhangelsk region, population mortality caused by diseases of the circulatory system is higher than the national average. The aim of this study was to assess ambient air quality in Arkhangelsk and associated health harm in adult population. The study relied on using data of ambient air monitoring in Arkhangelsk collected over 2011–2022. We analyzed average annual levels of 23 pollutants and primary incidence of diseases of the circulatory system (CVD) and calculated hazard quotients under chronic inhalation exposure (HQ), hazard index (HI) for the cardiovascular system, and the number of attributable deaths associated with exposure to PM10 and PM2.5. Over the analyzed period, the average long-term concentrations of most pollutants met hygienic standards. Average levels of formaldehyde, chromium, copper and benzene were found to exceed the MPL by 1.5–2.3 times. Hazard coefficients for formaldehyde (HQ = 2.3), copper (HQ = 1.8) and PM2.5 (HQ = 1.7) were established to be above their permissible value. The risk of developing general toxic effects is determined to be high (HI = 6.6) for the cardiovascular system. The main contribution to the risk level is made by copper and PM2.5. Attributable outcomes of primary cardiovascular incidence among the adult population of Arkhangelsk associated with exposure to PM10 and PM2.5 equaled 10.7 and 2.9 ‰ cases per year. The greatest harm under exposure to PM2.5 is due to the development of coronary artery disease and amounts to 1.9 ‰ cases per year.

A Review of the Difficulties Faced by Low and Middle-income Countries in Hygiene and Healthcare Practices.

Hygiene has been identified as an important step in anticipating health-related pol-lution, with conflicting reports about consistent sanitation standards in the nation. This narrative review of published studies has led to the discussion of hand hygiene and health practices, as well as the identification of necessary methods that are available in low and middle-income countries. An effective survey of accessible information is conducted in this way based on re-view questions. A number of 372 articles were found on the web, and 32 articles were used in the final analysis. Overall, the standard of hand hygiene is set at 20.49%. Difficulties identified for the people in low or middle-income countries are poor awareness and sound information about hand hygiene, lack of resources including water, soap, hand scrubbing gel, etc., as mis-interpretations related to hand hygiene practices. People are paying more attention to healthcare-related illnesses as it becomes increasingly clear that most of them may be pre-vented. The free evidence-based practice states that to lower the danger of contamination, hand hygiene should be properly adhered to. The difficulties recognized in this review are reliable, with the discoveries of studies that have been led somewhere else. By conducting a basic ex-amination of the "Clean Care is Safer Care" as an excellent arrangement of WHO's global initiative activity on patient well-being programs, developing nations will have more time to consider the essential approaches for the use of fundamental disease prevention exercises in our health care settings.

Implementing a Compliance Monitoring Process to Promote Chlorhexidine Gluconate Bathing and Hand Hygiene: An Initiative to Decrease Central Line–Associated Bloodstream Infections

Background Chlorhexidine gluconate (CHG) bathing has proven to reduce central line–associated bloodstream infections (CLABSI) in hospitalized patients. The aim of this study is to evaluate whether the implementation of a compliance monitoring process for CHG bathing and strict hand hygiene as part of the traditional CLABSI prevention bundle will reduce the overall hospital CLABSI standardized infection ratio (SIR). Methods A quasi-experimental study was conducted in intensive care and non-intensive care inpatient hospital units in an urban 361-bed teaching hospital in Western Pennsylvania. The pre-intervention period consisted of January–August 2021, the intervention period consisted of September–November 2021, and the post-intervention and sustainability period consisted of December 2021–June 2022. A compliance monitoring process for the initiation of a daily bath using a 4% CHG solution and strict hand hygiene surveillance was implemented as part of the standard CLABSI prevention bundle (which includes standardized insertion checklists and processes, daily necessity assessment, dressing change and integrity standards, five moments hand hygiene standards, CHG disk [Biopatch], end caps [Curos], and care of tubing). Outcomes A statistically significant increase in hand hygiene (p=<0.001) and in CHG bathing compliance (p=0.014) helped reduce the overall hospital CLABSI SIR from 1.45 to 0.82, standing for an overall 43.4% decrease. Cost reduction was statistically significant (p=0.011) and was an estimated $1.4 million dollars in savings for the hospital. Next Steps Incorporate the compliance monitoring component for CHG bathing and hand hygiene as part of the best strategy for CLABSI bundle prevention within the healthcare system.

Nationwide Investigation on Organophosphate Flame Retardants in Tea from China: Migration from Packaging Materials and Implications for Global Risk Assessment.

In this study, we measured 15 common organophosphate flame retardants (OPFRs) in six categories of tea samples across China. OPFRs were found in all the tea samples, with the total concentrations of OPFRs (∑OPFRs) at 3.44-432 ng/g [geometric mean (GM): 17.6 ng/g]. Triphenyl phosphate (TPhP) was the dominant OPFR, accounting for 39.0-76.2% of ∑OPFRs across all tea categories. The potential factors influencing the residual OPFRs in tea were thoroughly examined, including the agricultural environment, fermentation, and packaging of teas. Tea packaging materials (TPMs) were then identified as the primary sources of OPFRs in teas. The migration test revealed that OPFRs with lower molecular weights and log Kow values exhibited a higher propensity for facilitating the migration of OPFRs from TPMs to teas. The estimated daily intakes of OPFRs from teas were relatively higher for the general populations in Mauritania, Gambia, Togo, Morocco, and Senegal (3.18-9.79 ng/kg bw/day) than China (3.12 ng/kg bw/day). The health risks arising from OPFRs in Chinese teas were minor. This study established a baseline concentration and demonstrated the contamination sources of OPFRs in Chinese tea for the first time, with an emphasis on enhancing the hygiene standards for TPMs.

Food poisoning causes and prevention and what to know about hygiene

Food-borne diseases are the most common health problems globally, and they are particularly common in Third World countries like India due to poor public sanitation and hygiene. Broadly speaking, food poisoning refers to any illness brought on by eating food that contains bacteria or non-bacterial substances. Stated differently, it's an acute instance of gastroenteritis caused by ingesting chemicals-contaminated food or drink, animal or plant-derived poisons, or living microbes and their toxins. Acute gastroenteritis is one of the leading causes of morbidity and mortality. The most vulnerable are newborns and young children. The clinical symptoms of a foodborne infection are determined by the pathogenic mechanisms that underlie it. The main symptoms are headache, nervousness, intense thirst, abrupt vomiting, diarrhea, colicky discomfort, cold, clammy skin, slow heartbeat, rigours, and cramps. The provision of clean, drinkable water, appropriate disposal of human and animal sewage with isolation from water supplies, and fundamental food hygiene standards are all very effective ways to prevent the development of these disorders.

Моделирование системы очистки сточных вод животноводческих ферм

Among the sources of pollution of surface water bodies from agricultural activities, livestock, pig and poultry complexes can be prioritized, which are uncontrolled and diffuse sources of suspended solids, organic compounds, biogenic elements, heavy metals and pathogenic microflora, which causes biochemical pollution and has a particularly detrimental effect on the state of inland reservoirs. Wastewater from agricultural processing enterprises and household water from rural settlements with unpredictable pollutants play a significant role in pollution. The livestock sector is one of the largest consumers of water. The large number of animals in a confined space, the use of hydraulic harvesting systems when removing their waste products, leads to the formation of manure in significant quantities. Sanitary and hygienic standards in industrial premises are supported with the help of water – animals are washed with it, rooms are cleaned, and they are disinfected, food is prepared, dishes and equipment are washed, manure is washed off with water, and so on. Accordingly, as the demand for water in animal husbandry increases, the volume of wastewater discharge that contains manure into nearby water bodies increases. The effluents that are formed as a result of the activities of the livestock sector are classified as containing a large amount of harmful substances with a high concentration. Depending on the sources of pollution and the main pollutants, technical solutions should be developed to reduce the volume of wastewater and its treatment. The effectiveness of their functioning can be ensured with the help of modern information processing methods, using methods of system analysis of complex objects based on a mathematical description of the technological process. To analyze the state of the treatment system as a whole and predict the development of emergency situations, a software implementation of a wastewater treatment system for livestock farms was created.

Frequency of SARS-CoV-2 Infections among Healthcare Workers in Germany: 3-Year Follow-Up Study.

The emergence of SARS-CoV-2 in 2019 led to a global pandemic with a significant impact on healthcare systems. Healthcare workers were particularly vulnerable due to frequent contact with COVID-19 patients. Despite vaccination, they remained at higher risk as the vaccines provided limited protection against infection with viral variants, like Delta or Omicron BA.1 and BA.5. Three years after the onset of the pandemic, we evaluated SARS-CoV-2 infection frequencies among healthcare workers with varying levels of patient contact: high-risk (frequent COVID-19 patient contact), intermediate-risk (non-COVID-19 patient contact), and low-risk (no patient contact). We assessed their cellular and humoral immune responses based on their vaccination status and number of prior infections. SARS-CoV-2-specific antibodies were measured by immunoglobulin ELISA, and neutralizing antibody titers were determined against the viral variants D614G, Delta, and Omicron BA.1 and BA.5. Cellular immune responses were analyzed using an interferon-γ ELISpot. Notably, three years into the pandemic, healthcare workers in daily contact with COVID-19 patients did not have higher infection rates compared to healthcare workers with non-COVID-19 patient contact or no patient contact. Immune responses were similar across all groups, highlighting the effectiveness of vaccination and current hygiene standards in preventing virus transmission from patients to staff.

Monitoring of atmospheric air quality in cities participating in the federal project “Clean Air” of the Far Eastern Economic Region

Introduction. Air pollution over 2021 was associated with about 6.7 thousand additional deaths and almost 1.1 million additional cases of illness among the Russian population. Conducting an atmospheric air quality assessment for the subsequent selection of priority measures aimed at reducing its negative impact on public health is the main task of the Clean Air federal project. The aim of the study is to assess the management of monitoring and air quality in the cities of Komsomolsk-on-Amur, Petrovsk-Zabaykalsky, and Ussuriysk before the implementation of the federal project “Clean Air”. Materials and methods. The monitoring programs for atmospheric air quality, the results of laboratory studies for 2021 were used. The number, location of observation posts, volumes, frequency of sampling, a list of indicators, the total number of samples, the number of samples exceeding the MPC, average annual, maximum one-time concentrations of pollutants were analyzed. Results. In Komsomolsk-on-Amur, atmospheric air quality monitoring was carried out at 4 stationary and 3 route posts, Ussuriysk – 1 mobile and 1 stationary post, Petrovsk-Zabaikalsky – 1 stationary post. All studied cities are characterized by systematic excesses of hygienic standards for specific indicators. The level of air pollution in the city of Komsomolsk-on-Amur is assessed as very high, in the cities of Ussuriysk and Petrovsk-Zabaikalsky – low. Despite the low level of air pollution, these towns are characterized by systematic excesses of hygienic standards of some indicators. Limitations. The study analyzed the management of monitoring and the results of laboratory studies of atmospheric air only in the cities of Komsomolsk-on-Amur, Ussuriysk, Petrovsk-Zabaykalsky. Conclusion. The existing monitoring system in the Ussuriysk, Komsomolsk-on-Amur and Petrovsk-Zabaykalsky cities fails to allow an objective assessing of the quality of atmospheric air and its impact on public health. To objective evaluation of the impact of atmospheric air quality on the health of the population of the studied cities, measures to optimize the monitoring system were proposed.
