Approximately 5% of U.S. adults have some form of visual impairment, underscoring the importance of inclusive design. Key recommendations include ensuring sufficient color contrast (minimum ratios of 3:1 or 4.5:1 depending on text size), using structural elements like patterns or shapes to differentiate data for colorblind readers, optimizing font styles and sizes for readability, and providing concise, descriptive alternative text for screen readers. These practices not only accommodate individuals with permanent or temporary limitations but also improve the overall usability and comprehension of figures for all readers, fostering broader engagement and equitable access to scientific knowledge.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"126–132 126–132"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.chas.4c00141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675857","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}

Here, six Volatile Organic Chemicals (VOCs) were identified in emissions from an entry-level VP printer using both Standard and “Eco” resin formulations and quantified in four phases of the VP printing process. To the best of our knowledge, this work is the first to assess emissions of “Eco” resins. Two shapes were printed to assess the impact of the surface area on emissions. Emissions were greatest for two monomers, 2-hydroxyethyl acrylate and 4-acrylomorpholine. Mesitaldehyde, tolylene-2,4-diisocyanate, 2,6-di-<i>tert</i>-butyl-p-cresol, and dipropylene glycol diacrylate emissions were more consistent. Generally, Standard resin emissions exceeded Eco resin emissions. Object surface area did not have a clear impact on emissions. Similar or higher emissions from idle printers with an uncovered resin vat compared to emissions from active printing were observed. For the first time, it was demonstrated that idle printer emissions were reduced drastically (by 70–97%) using a fabricated vat lid, demonstrating the importance of a sealed resin vat to reduce VOC emissions. Where available, reference exposure limits for the VOCs measured were compared with total emissions; this analysis indicated that these emission rates lead to exposures approaching or exceeding available exposure thresholds. These results show that a simple mitigation strategy and, to a lesser extent, the use of a low-VOC resin should lower the emissions of VP printers and, as such, reduce VOC exposures for the users of VP Printers.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"175–185 175–185"},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.chas.4c00087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675705","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}

This study aimed to evaluate the ecotoxicity of entecavir (ETV), an antiviral used to treat hepatitis B, in models of <i>Aliivibrio fischeri</i>, <i>Microcystis novacekii</i>, <i>Artemia salina</i>, and <i>Biomphalaria glabrata</i>, which directly interferes with enzymatic processes and protein synthesis, possibly impacting the environment and human health. In the ecotoxicological tests, the organisms were exposed to ETV concentrations ranging from 0 to 300 mg/L at 30 min to 96 h intervals, depending on the model used. Only toxicity results at concentrations below 100 mg/L were considered environmentally relevant. Statistical analyses for the <i>A. salina</i>, <i>M. novacekii</i>, and <i>B. glabrata</i> models were conducted using dose–response regressions. Mortality in the <i>B. glabrata</i> model was assessed using the Kruskal–Wallis test. For the model with <i>A. fischeri</i>, the analyses were performed considering the mean bioluminescence values against the control (sample without ETV) on a logarithmic scale with the <i>R</i>² determination index as the reference for the fit under the standard Microtox procedure. A significance level of 5% was adopted for all analyses. None of the biological models exposed to ETV showed toxicity at environmentally relevant concentrations (&lt;100 mg/L). Although it may seem that ETV does not pose a risk to the environment due to its low ecotoxicological spectrum, given the lack of toxicity observed in the models tested and the nondetection of ETV in the environment, the rational use, disposal, treatment, and final disposal of pharmaceutical waste of this drug, the monitoring of pharmaceutical waste in sewage and water treatment systems and the improvement of these systems should be encouraged to mitigate possible environmental, economic, and health impacts.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"165–174 165–174"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.chas.4c00084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675730","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}

Major incidents in academic and industrial settings are commonly used in the form of case studies to suggest lessons and inspire change; however, a truism of safety studies is that major incidents often arise from the same causes as those that previously caused minor events that remained unaddressed. However, major events make up only a very small percentage of the events that could, with multiple failures, lead to the adverse outcomes. In this study, we examined 258 routine safety incidents reported between 2016 and 2020 at a major petrochemical processing facility site in North America. Restricting the analysis to incidents that included both chemicals and human error reduced the sample to 75 incidents that were categorized via quantitative content analysis. Findings showed a significant effect of day of the week; most incidents involved mid-operation errors and related to administrative issues. Findings highlight a culture of reporting even superficially minor incidents, which may lead to improved safety-implementation policies that could help prevent major incidents from occurring. We propose a crude measure to determine the rigor of a reporting culture: the incident severity reporting threshold index, the ratio between the number of incidents involving injuries, and the total number of reported incidents. We strongly suggest that the severity threshold for reporting be lowered so as to address hazards and emergent risks before they have an opportunity to become dangerous. The implications of incident reporting and safety in industry are considered in relation to academic settings.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 2","pages":"186–193 186–193"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degradation experiments were systematically conducted under varying operational conditions, including the pH, initial dye concentration, and catalyst dosage.
