Because manually introducing information piecemeal from thousands of Safety Data Sheets (SDSs) into other required lists is labor intensive, this project provides a stand-alone application that can populate the required information within minutes and be easily used by any employee. Though the application is currently limited to the Romanian language and there are certain improvements that can be addressed within the script, as it stands, the application can fulfill its purpose.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266896","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}

{"title":"Calix[4]resorcinarenes as Stable, Metal-Free Unexplored and Unfathomed Material for Iodine Capture: Experimental and Theoretical Insights","authors":"Gopika Jagannivasan, Jayasree G Elambalassery, Suja Haridas","doi":"10.1021/acs.chas.4c00037","DOIUrl":"https://doi.org/10.1021/acs.chas.4c00037","url":null,"abstract":"While nuclear power offers a viable solution to the ever-growing energy demands, the piling up of nuclear waste remains a looming threat, endangering life on Earth. Safe disposal of radionuclides, especially highly volatile ones such as iodine, is a grave concern to be addressed for operational safety. Even though porous adsorbents for iodine capture have been widely investigated, less focus has been directed toward nonporous materials. Herein, we describe the synthesis of nonporous, macrocyclic Calix[4]resorcinarenes (C4Rs) via a near solventless green protocol mediated by Keggin-type phosphovanadotungstic acid and avoiding the use of mineral acids. The applicability of the synthesized C4Rs for iodine absorption at elevated temperatures has been explored. Facile synthesis strategy and metal-free nature coupled with moisture and temperature stability endorse our interest in C4Rs as highly attractive substrates for iodine sorption, with the substituent functionalities playing an important role in adsorption efficiency. We hereby report a novel C4R, DEAS, with an exceptional iodine sorption capability. The retention of iodine in the macrocyclic framework, mainly in the form of polyiodides, could be ascertained through a detailed characterization. The adsorption was found to follow pseudo-second-order kinetics. The adsorption of iodine from an aqueous solution was also subjected to investigation. Furthermore, theoretical investigation into the guest–host interactions between C4Rs and I₂ has been attempted for better insights.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184003","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}

As more projects explore ammonia-fueled vessels, safety concerns, particularly the acute toxicity and risks of ammonia release, are paramount. This research focused on the effects of accidental ammonia releases during ship-to-ship collisions, affecting ammonia tank integrity. We examined various release scenarios, considering factors like tank types and locations, breach sizes and positions, weather conditions, and dispersion patterns, using PHAST software for modeling. Results indicated that semipressurized tanks pose greater health risks on human health than fully refrigerated ones. Underwater releases are less hazardous, as a significant amount of ammonia dissolves before surfacing. Mitigation efforts, such as water curtains and containment basins, were evaluated for their effectiveness in minimizing the impact of ammonia releases. These measures significantly reduce risks to nearby populations but are less effective for crew safety onboard. This underscores the challenge of ensuring onboard safety in ammonia-fueled vessels, highlighting the need for innovative and effective safety design.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184004","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 photodegradation of TC is an effective strategy for overcoming antibiotic pollution in the water environment. Fe–In₂O₃/In₂S₃ composites were successfully synthesized via a hydrothermal method for the photocatalytic degradation of TC under visible light illumination. When the Fe doping content was 2%, the degradation rate of TC by the 2% Fe–In₂O₃/In₂S₃ composite under visible light irradiation reached 92.4%, which was higher than that of 41.5% for In₂O₃/In₂S₃, 86.7% for 1% Fe–In₂O₃/In₂S₃ and 79% for 3% Fe–In₂O₃/In₂S₃. The photodegradation of tetracycline on Fe–In₂O₃/In₂S₃ was a first-order reaction under visible light. The rate constant of photocatalytic tetracycline degradation was 5.12 × 10^–3 min^–1, which was 4.1 times greater than the rate constant of In₂O₃/In₂S₃. The characterization results revealed the excellent separation efficiency of the 2% Fe–In₂O₃/In₂S₃ composites for photogenerated electron–hole pairs, which increased the photodegradation efficiency. Furthermore, under the most suitable reaction conditions, the photodegradation rate of tetracycline was 92.4%. A mechanistic study revealed that the doping of Fe ions effectively improved the transfer efficiency of photoproduced charges and inhibited the combination of photoproduced electron–hole pairs, thereby improving the photocatalytic performance of the material and achieving efficient oxidative degradation of tetracycline.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184005","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}

While all facilities handling hazardous materials should follow the hierarchy of process safety controls, the nature of research laboratories is often such that flammable vapors or gases are unavoidable. Accordingly, the use of hazardous area electrical classification is a key component of an overall ignition source control strategy. This article outlines major concepts associated with area classification for vapors and gases in the context of the hierarchy of controls, and offers practical suggestions for how to limit risk in research laboratories.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184010","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}

Between 2015 and 2019, 1015 radiation workers in Bangladesh who were under observation for their personal dose equivalent were reported. There were 417 physicians among them, while the remaining personnel included radiological technologists, physicists, and other medical staff members. To measure the exposure dose, a conventional TLD-100 (LiF:Mg, Ti) was used. A Harshaw TLD reader (Model 4500) was used to read the TLDs on a quarterly basis. All of the monitored workers, who made up around 19.11% of the total, had ionizing radiation exposure below the limit established by international organizations. The Mann–Kendall trend test and Sen’s slope estimator were also applied to the annual collective effective doses, and it showed a decreasing trend over the time frame. The current state of occupational exposure and its trends show that most workplaces have effective radiation protective measures in place.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184008","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}

We highlight the risks associated with uncritically accepting initial safety claims in the chemical literature, especially when such claims are later retracted or corrected. Our analysis focuses on three specific cases where procedures initially deemed safe necessitated significant safety corrections, and we emphasize the inadequate response of the publishing community to these updates. It is important to note that safety corrections often remain less visible and less cited than the original flawed publications. We scrutinize the mechanisms publishers employ for marking safety-related corrections and retractions and find them inconsistent and insufficiently visible to alert researchers, particularly trainees and those with less experience. We propose more effective strategies to enhance the clarity and prominence of safety information, including mandatory peer-review by chemical safety specialists and prominent watermarking of papers with safety corrections. We also advocate for authors and reviewers to use a safety checklist that includes detailed hazard identification, clear storage and handling instructions, and justification of hazardous reagents. Our Commentary underscores the shared responsibility across the scientific ecosystem in maintaining safety standards, advocating for a proactive role by journal publishers in protecting researchers from hazardous procedures and compounds, thus prioritizing safety in the publication of chemical research.","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184009","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}

{"title":"Reflections in Chemical Safety and Research: Doing Science Against All Odds in the Philippines","authors":"Imee Su Martinez","doi":"10.1021/acs.chas.4c00049","DOIUrl":"https://doi.org/10.1021/acs.chas.4c00049","url":null,"abstract":"Imagine yourself as an idealistic recent university graduate, who has been recruited by the Institute of Chemistry University of the Philippines-Diliman for tenure track with a relatively decent repatriation package. You start dreaming about starting your own laboratory and doing novel research work that has never been done before in your home country. You feel really good about yourself, thinking that you will be contributing to national development by mentoring the cream of the crop, leading researchers in advancing science and technology in the country. And then you start working in the laboratory. For the first part of your work, you need nitric acid, a regulated chemical. You realize that it takes a ton of paperwork to procure and at least a week to acquire. Your timeline is still doable, so you feel this is just a minor setback. Then the next phase requires equipment purchasing, and this is when reality hits you, because by then you realize that it takes years to actually procure this piece. Research in the Philippines in general, and particularly in the University of Philippines (UP), is quite challenging─to put it mildly. We do not worry about the science and the problem solving, nor about funding, which is a concern for every researcher around the globe. I wish that looking for the next meal ticket were our focus, because we researchers are trained to solve problems and write proposals to secure funding. But our problem is something else entirely. Ingrained regulations─or perhaps <i>restrictions</i> is the better word─appear, from funding utilization to procurement to safety. Many of these rules seem designed to impede researchers from performing their tasks efficiently. Is our lack of a research culture preventing us from striking the necessary balance between regulatory compliance and functional efficiency? Is our insufficient research experience compared to other countries cause for regulations or policies that may affect research? Is our interpretation of the law keeping us from moving forward at a pace that is on par with the rest of the world? Research and innovation are established key factors in attaining sustainable national development. Clearly, an enabling, nurturing environment conducive to work is essential. We all agree that research funding require due diligence, especially government-provided funds from citizens’ tax payments. We are painfully aware that as a developing country, we need to be very conscientious about how we use money for research. The laser, hood, safety shower, and vacuum line in my laboratory could have been housing and food for our fellow Filipinos. But how would our nation benefit if the science community could not use funds at all? How would our nation gain ground in research when young researchers are demoralized because of delayed salaries due to a regulation in transferring and receiving research funds. Are not the Commission on Audit Circular No. 94-013 and related regulations meant to expedite t","PeriodicalId":12,"journal":{"name":"ACS Chemical Health & Safety","volume":null,"pages":null},"PeriodicalIF":0.73,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141754177","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}
