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 <i>P</i>-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.</p>","PeriodicalId":11827,"journal":{"name":"Environmental Health Insights","volume":"19 ","pages":"11786302251317056"},"PeriodicalIF":2.3,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11780630/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143064816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widely consumed in Ghana, sachet water has become a convenient and affordable option, with over 37% of the population depending on it.

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.

The annual number of medical visits of rural residents was evaluated via multiple regression, and the Pearson correlation and Granger causality tests were used to evaluate the relationships between coal consumption and the changes in mortality rates of various diseases in rural areas. The results revealed that coal consumption for domestic use had a significant (<i>P</i> < .001) positive effect on the frequency of medical treatment, whereas this effect was not significant at the production end. Significant positive correlations existed between coal consumption in rural areas and increased mortality rates for 7 out of the 10 main diseases. Causal relationships were identified between coal consumption and increased mortality rates due to urogenital system diseases and nervous system diseases. The empirical results of this study suggest that the gradual promotion of clean energy replacement of coal with electricity and natural gas in rural areas should reduce the probability of exposure to gas emitted from coal combustion for rural residents.
