Acrylamide is a contaminant prevalent in many commonly consumed foods, contributing to unavoidable human exposure. It is recognized as likely to be carcinogenic to humans as well, provoking global concerns. Numerous studies have investigated the impacts of acrylamide formation on food and drink, nutrition, and health. The intent of this analysis is to quantify global acrylamide research, evaluate recent developments, and recognize emerging trends, along with assessing research dynamics as an indicator of innovation among the scientific community. The Scopus database was used to perform an in-depth investigation of scientific publications on acrylamide from 1949 to 2023. Exploring prominent topics and the knowledge network related to the topic was conducted via VOSviewer version 1.6.20. Additionally, using SciMAT software, intellectual analysis was conducted to identify both driving and emerging themes in acrylamide-related research. A total of 11 880 publications on acrylamide were identified, with 10 720 (90.24%) being original articles. The leading contributors in terms of publication output were China (n = 2452; 20.64%), followed by the USA (n = 1564; 13.16%), and India (n = 952; 8.01%). The predominant themes were associated with (a) the functionalization of acrylamide polymers and (b) the formation and mitigation of acrylamide in food and drinks. Driving themes that will continue to shape the future of acrylamide research involve unraveling the synthesis of acrylamide; deploying acrylamide in nanocomposites to increase contaminant removal; investigating the genotoxicity of acrylamide, as well as its carcinogenic, reproductive, and neurotoxic effects; and researching the adsorption characteristics of acrylamide in aqueous solutions. In particular, an increased focus has been placed on understanding the formation and mitigation of acrylamide in recent years, signifying increased attention and alignment with the latest scientific advancements in this field. The creation of research plans in this way is significant, particularly in shaping future health policies.

Ponds in Kathmandu Valley reflect its rich history with water resources, but increasing pollution threatens public health and the environment. This study aimed to assess the physicochemical and microbial quality of pond water and further analyze the factors influencing E. coli contamination. In 2023, water samples from 27 out of a total of 35 ponds were examined for physicochemical parameters (temperature, pH, TSS, turbidity, iron (Fe²⁺), nitrite (NO₂ ^-), phosphate (PO₄ ^3-), ammonia (NH₃), DO, BOD, and COD) and microbial parameters (total coliforms and E. coli). Results revealed that all ponds exceeded WHO limits for TSS and turbidity for drinking water. Furthermore 67% surpassed the iron limit, while 96% exceeded USEPA's BOD and COD levels for supporting aquatic life. Coliforms were present in all ponds, with E. coli detected in 67%, indicating the water was unfit for drinking under EU guidelines. Logistic regression revealed a significant association of COD and temperature (P-values 0.001 and 0.023 respectively) with E. coli presence. A 3D visualization of the data further supports the association and illustrates these relationships, COD having a greater impact. These findings underscore public health risks and environmental concerns, urging sewage and runoff management and recommending expanded seasonal studies to establish comprehensive water quality guidelines.

Climate change-induced flooding has caused public health crises in Borno State, Nigeria, which influence the increase of waterborne diseases and malnutrition. Flooding disrupts water and sanitation systems, creating breeding grounds for waterborne diseases such as cholera, malaria, and diarrheal illnesses. The displacement of communities and destruction of agricultural infrastructure due to flooding further increase food insecurity, leading to malnutrition. This paper examines the interplay between flooding, waterborne diseases, and malnutrition in Borno State, highlighting the urgent need for climate adaptation strategies and strengthened healthcare systems to mitigate these public health challenges. Additionally, it highlights the double burden of conflict and climate change where ongoing conflicts impede efforts to mitigate and adapt to climate change. Finally, this paper outlines the socio-economic impacts of flooding and proposes interventions to mitigate the effects of flooding.

Background: An edible oil factory is a labor-intensive and technologically complex industry, with workers potentially exposed to a variety of dangers associated with such industries. Personal protective equipment is a universal, legal requirement, and an important strategy for preventing occupational injuries and illnesses caused by workplace hazards. However, such industries receive little attention, especially in Ethiopia.

Objective: To assess personal protective equipment utilization and its associated factors among workers in the PhiBela edible oil factory in Burie, Ethiopia, in 2022.

Methods: A cross-sectional study was employed among the PhiBela edible oil factory workers in Burie. A simple random sampling technique was used to select 389 PhiBela edible oil factory workers. Face-to-face interviews and self-administered structured questionnaires were used to collect data on workers' protective equipment utilization practice, socio-demographic, work-related, environmental, and organizational factors. Data was analyzed using SPSS version 25. The logistic regression method was used to see factors associated with workers' protective equipment utilization. The strength of the association was calculated using an odds ratio at 95% confidence intervals.

Results: Of the total workers, 216, 55.52% (48.33-57.78) workers utilize personal protective equipment in the factory. The study showed safety training [AOR (4.68, 95%CI (2.76-7.45)], availability of personal protective equipment [AOR = 4.86; 95%CI: 2.23-6.98], regular health and safety supervision [AOR = 2.751; 95%CI: 1.806-3.801], availability of safety guideline at workplace [AOR = 3.798; 95%CI: 1.248-6.173], having work experience 3 years and above [AOR = 1.64; 95%CI: 1.06-2.18], not using alcohol [AOR = 3.07; 95%CI: 2.11-4.76], and not smoking cigarette [AOR = 1.88; 95%CI: 1.55-3.11] were predictors of personal protective equipment utilization.

Conclusion: The level of personal protective equipment utilization among Phibela edible oil factory workers is 55.52%, which is moderate when compared to other studies done in developing countries. The presence of Safety training, availability of personal protective equipment, regular health and safety supervision, availability of guidelines at workplaces, having work experiences, not using alcohol, and cigarrete smoking were factors found to be a significant predictors of personal protective equipment utilization. As a result, close workplace supervision, safety training, and availing guidelines are the recommendations to be in place.

Biomass smoke exposure represents a critical health concern, especially for those in occupational settings such as fish smoking. While substantial research has addressed indoor air pollution from domestic cooking, the specific risks faced by fish smokers have received insufficient attention. This study sheds light on the alarming relationship between smoke exposure and health issues among commercial fish smokers in Abuesi, Ghana. Through a comprehensive cross-sectional analysis involving 302 participants, we utilized structured questionnaires and expert eye assessments to gather vital data. Our statistical evaluation, including descriptive statistics, ANOVA, and chi-square tests, revealed a troubling prevalence of respiratory symptoms such as cough, asthma, and breathlessness, all significantly linked to prolonged smoke exposure. Eye health findings were equally concerning, with distant vision impairment affecting 26.37%, eye discomfort reported at 53.02%, and notable rates of cataracts (28.6%) and refractive errors (17.9%). For those suffering from breathlessness, asthma, and pneumonia, the data indicated that longer exposure durations correlated with more severe health outcomes. Specifically, subjects without breathlessness had an average smoking duration of 14.84 years (SD = 12.29) compared to just 10.26 years (SD = 11.15) for those with the symptom-a statistically significant P-value of .014. Asthma and pneumonia exhibited similar trends, highlighting a distressing reality: shorter smoking histories align with more severe health conditions, suggesting that such symptoms might drive smokers to abandon their practices prematurely. Given the serious health risks tied to traditional fish smoking practices, this study strongly advocates for the implementation of improved smoking technologies, better ventilation systems, and comprehensive health education initiatives. These measures are essential to safeguard the health of those involved in this vital industry and reduce exposure to hazardous smoke.

The study, aligned with Sustainable Development Goal 7: Affordable and Clean Energy, emphasizes the urgency of promoting clean energy alternatives, improving cooking practices, and addressing the health and environmental impacts of solid fuel usage to foster a more sustainable energy landscape in Somaliland.

Introduction: Access to safe drinking water is crucial for health and survival, yet many developing countries face significant challenges in this regard. In West Africa, rapid urbanisation has outpaced efforts to improve access to potable water, compelling households to rely on private vendors for solutions, particularly through the growing market for sachet water. Widely consumed in Ghana, sachet water has become a convenient and affordable option, with over 37% of the population depending on it. However, concerns about its microbial safety persist, as studies indicate that sachet water often fails to meet necessary safety standards. This review consolidated existing research on microbial contaminants in sachet water, aiming to provide a representative overview of the microbial quality of sachet water in Ghana.

Method: The systematic review followed the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A thorough literature search was conducted across multiple databases, including PubMed, Web of Science, ScienceDirect, Scopus and the search engine Google Scholar, using relevant search terms. Eligible studies were identified based on established criteria, and data were subsequently extracted and analysed.

Results: A total of 28 studies published from 2003 to 2024 were selected for inclusion in this review. Notably, 96% of these studies reported bacteria from 17 different genera, while 11% examined parasites from 5 genera. Some studies (7%) investigated both types of contaminants. Overall, 2,276 sachet water samples were analysed, with 1,727 (76%) showing microbial contamination. Escherichia coli was the most identified bacteria, while Cyclospora cayetanensis and Cryptosporidium parvum were the most identified parasites.

Conclusion: This study highlighted critical public health risks associated with sachet water in Ghana, particularly the presence of harmful bacteria and parasites. It is important to implement stricter manufacturing and sanitation standards and encourage safe handling practices to ensure the safety and quality of sachet water. Additionally, future research should focus on bridging existing gaps by investigating parasitic, viral, and fungal contaminants, to provide a holistic overview of the microbial contaminants in sachet water in Ghana.

Exposure to ambient air particulate matter (PM_2.5) pollution presents a significant public health and economic challenge in Addis Ababa, Ethiopia. This thesis used the Environmental benefits mapping and analysis program-community edition (BenMAP-CE) software tool to estimate health and economic impact of ambient air PM_2.5 pollution. The study evaluated the impact of decreasing the annual average PM_2.5 concentration in 2019 (32.8 µg/m³) to different international and national air quality standards, including World health Organization's guidelines and the Ethiopian National Ambient Air Quality standard (NAAQS). Results showed that Addis Ababa exceeded both WHO's and Ethiopia's ambient air quality standards in 2019. The study estimated the attributable deaths from cardiovascular, ischemic heart disease (IHD), stroke, chronic obstructive pulmonary disease (COPD), and lower respiratory infection (LRI) due to PM_2.5 exposure across 3 reduction scenarios. Additionally, economic benefits associated with avoided deaths were quantified using the Organization for Economic Cooperation and Development (OECD) Value of Statistical Life (VSL) methodology. The finding demonstrated that reducing PM_2.5 pollution levels led to a notable decrease in mortality rates from various health conditions in Addis Ababa. Moreover substantial economic benefits, amounting to millions of dollars, were observed across all health endpoints, indicating significant societal savings. This study underscores the importance of implementing interventions to mitigate PM_2.5 pollution for improved public health and economic well-being in Addis Ababa and similar urban settings.

Background: Wastewater treatment is crucial to protecting public health and the environment by removing Biohazards. In Ethiopia, however, significant research gaps limit progress, especially regarding the efficiency of Biohazard removal in existing treatment facilities. This review evaluates the effectiveness of current treatment methods for Biohazard removal, highlights key challenges, and offers recommendations.

Methods: This scoping review followed PRISMA guidelines, systematically searching databases like NLM. Science Direct, HINARI and Scopus for Biohazard removal studies in Ethiopia, with independent reviewers screening and analyzing relevant data to identify key challenges.
