Despite having various sectoral legislative frameworks, there is a notable absence of a comprehensive legal framework specifically addressing chemical safety management issues. Moreover, the existing regulations have not successfully established a nexus between chemical safety, employee well-being, potential opportunities, and task performance. This highlights the insufficient attention given to occupational health and chemical safety issues at the policy level, with limited research dedicated to these critical concerns. Consequently, this critical review aims to identify optimal strategies for the long-term sustainable development of Bangladesh in the realm of occupational chemical safety and management. The review critically evaluates the current state of Bangladesh's national chemical management, offering a policy trajectory for consideration. It meticulously analyzes the disjunctions and incongruities between prescribed guidelines and actual practices in chemical management within the Bangladeshi context. Furthermore, it establishes a comprehensive framework for a nationwide chemical management system, aligning with global best practices and guidelines. The study also delineates existing gaps and challenges while outlining future priorities that warrant immediate government attention and sustained commitment to enhance chemical safety management. Therefore, this study serves as a foundational reference for policymakers not only in Bangladesh but also for those in other developing economies grappling with escalating chemical demands, providing guidance for constructing an appropriate infrastructure and legal framework for enduring chemical management.</p></div>","PeriodicalId":73269,"journal":{"name":"Hygiene and environmental health advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773049224000230/pdfft?md5=c11a758857e7fdba9fa43884960952d5&pid=1-s2.0-S2773049224000230-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142240646","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}

Chronic colonization with increased intestinal permeability that permits the translocation of toxins and metabolites may partially explain this expanded disease manifestation. Currently there is little evidence in support of a role for toxins however, and greater evidence to support the role of metabolites in extra-intestinal disease pathogenesis. Specifically, increased levels of p-cresol, p-cresyl sulfate, indoxyl sulfate and ammonia are associated with <em>C. difficile</em>colonization. One important health consideration involves ongoing biotransformation of such metabolites, together with the overall metabolic load from all endogenous and exogenous sources, that can result in glutathione depletion. Chronic glutathione depletion in turn increases oxidative stress and is correlated with neurological compromise across all age groups, and a host of other conditions. Key factors supporting chronic colonization with <em>C. difficile</em> in susceptible hosts include widespread and indiscriminate use of antimicrobials, pharmaceuticals, pesticides, intensive agricultural practices, diet, food additives, and gastrointestinal disturbances.

Herein, Cu/Fe bimetallic nanoparticles (BNPs) were prepared and the use of these particles was investigated for the removal of BDE-209 from soil. Optimal conditions, including 9.1 wt% Cu loading and acidic environments, were identified to enhance the removal efficiency. The process involves desorption from soil, adsorption onto BNPs, and subsequent degradation. The contributions of adsorption and degradation were investigated by isolating the BNPs after the experiments conducted herein. Initially, adsorption played an important role, accounting for 25 %–38 % of the total removal, but this decreased to 14 % to 20 % as the reaction progressed, reaching at the equilibrium adsorption capacity after ∼3 h.

These challenges can lead to health issues, like urinary tract infections (UTIs), diarrhea, rashes, etc. The study objective was to understand the relationship between lack of access to basic hygiene facilities and health effects among unsheltered individuals. A verbal survey (English and Spanish) was used to explore the relationship between hygiene and unsheltered status. In Fall 2022, a researcher accompanied the homeless outreach team from El Rio Health, a Federally Qualified Health Center in Tucson, Arizona to verbally consent and recruit participants. Thirty consenting unsheltered adults ranging in ages from 29 to 68 years old participated in the study. Access to water was the greatest reported hygiene barrier, followed by access to soap, concerns for privacy, and concerns for safety. Eleven of thirty participants experienced a UTI at least once since becoming unsheltered and nine of thirty experienced a yeast infection at least once, with female participants having a statistically significant (<em>p</em> &lt; 0.05) higher rate of occurrence than male participants. In addition, 19/30 of participants experienced a rash at least once and 17/30 of participants experienced diarrhea at least once. However, 20/30 of participants did not seek medical care for their health-related issues.
