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":"18 1","pages":""},"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":"12 1","pages":""},"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":"67 1","pages":""},"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}

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":"177 1","pages":""},"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":"26 1","pages":""},"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}
