The suitable conditions for the preparation of I−BCSA in this system were with an excessive addition of 6 wt% of SO<sub>3</sub> in the raw meal, at a calcination temperature of 1250 °C for 1.5 h, and an added−gypsum content of 15 wt%. Under this suitable preparation condition, the contents of ye'elimite, dicalcium silicate (C<sub>2</sub>S) and tetracalcium aluminoferrite (C<sub>4</sub>AF) in I−BCSA clinker were 29.17 %, 50.23 % and 16.71 %, respectively. In addition, the impurity ions (Mg, S and F ions) hindered the transformation of α′<sub>H</sub>−C<sub>2</sub>S into α′<sub>L</sub>−C<sub>2</sub>S during the cooling process of clinker by causing the distortion and the inside porosity decrease of α′<sub>H</sub>−C<sub>2</sub>S crystal (phase transition energy barrier: 254 eV → 553 eV). This resulted in 20.49 % of the C<sub>2</sub>S in the I−BCSA clinker existing in the α′<sub>H</sub> crystal form. The presence of C<sub>4</sub>AF and α′<sub>H</sub>−C<sub>2</sub>S in clinker significantly improved the strength development of the product before 28 days. At a water/cement ratio of 0.35, the 3−day, 7−day, and 28−day compressive strengths of I−BCSA paste reached 43 MPa, 51 MPa, and 66 MPa, respectively, basically surpassed the strength development of commercial cement (including 42.5−grade of R–type OPC and CSA) exhibiting good early strength, under the same conditions. Moreover, the hydration products of I–BCSA were mainly ettringite, C–S–H gel, Fe(OH)<sub>3</sub> gel, Al(OH)<sub>3</sub> gel, C<sub>3</sub>(A, F)·6H<sub>2</sub>O and CaCO<sub>3</sub>, with relative proportions of 50.13 %, 36.06 %, 4.57 %, 4.21 %, 2.54 % and 2.49 %, respectively. From the perspective of hydration products, the synergistic support of ettringite and C–S–H gel was more conducive to the strength development of paste than the support of ettringite or C–S–H gel alone. Finally, the long–term (after 28 days) performance of I–BCSA still needs to be further studied in the future to promote the practical application of I–BCSA.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"286 ","pages":"Article 122778"},"PeriodicalIF":7.7,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the temporal changes in heat-related mortality in relation to the implementation of the HHAPs across five major cities of Australia, including Melbourne, Sydney, Brisbane, Adelaide, and Perth. Daily mortality and temperature data from 1999 to 2019 were analysed using distributed lag non-linear models to compare the heat-related mortality attributable fractions (AF%) between pre- and post-HHAP periods. The results showed an overall reduction in heat-related mortality after HHAP implementation, with a notable 0.12 % (95 % CI: −0.28 - 0.04) decrease in mortality attributable to extreme heat across five cities. The reduction was more evident in individuals aged 75 and older (−0.18 %, 95 % CI: −0.35 - 0.01), while the 0–74 age group saw slight increases (+0.13 %, 95 % CI: −0.13 - 0.39). Heatwave-related mortality showed general reductions or slight increases across cities, with AF differences in period 2 and 1 ranging from −0.20 % to +0.01 %. Brisbane, Perth, Sydney, and Adelaide witnessed notable AF decreases or minimal increases in period 2 across different definitions of heatwaves (−1.38 % to −0.01 % in Brisbane, −2.01 % to +0.05 % in Perth, −0.19 %–0.00 % in Sydney, and −0.71 %–0.17 % in Adelaide). In Melbourne, AF increased notably in period 2 for low-intensity heatwaves (≥2 days + 90th/92th percentile) by +0.25 % and +0.38 %, primarily due to the increase among those aged 0–74. Meanwhile, Sydney showed AF increases by +0.08 % to +0.43 % among the elderly during low-intensity heatwaves despite overall AF reductions. These findings suggest that HHAPs have reduced heat-related mortality in Australia's major cities, particularly during extreme heat days.

Associations between prenatal metal exposure and obesity in children were explored using the generalized estimating equation (GEE), latent class growth analysis (LCGA), and quantile g-computation models. After adjusting for confounders, mercury (Hg) showed a very weak opposite association with zBMI, overweight, and obesity according to the GEE model. A one-unit increase in the log<sub>2</sub>(Hg) was associated with an approximately 3 % reduction in the odds of obesity. Similarly, lead and cadmium were associated with a slight reduction in zBMI.

In this study, we investigate the diversity and stability of eukaryotic planktonic microbial communities in the glacial lakes at different developmental stages on the Qinghai-Tibet Plateau (QTP) through 18S rDNA gene amplification sequencing. Our results indicated that both the diversity and stability of the eukaryotic communities initially increased and then declined as the glacial lakes matured, with the species showing increasing environmental adaptability. Following cessations of glacial meltwater inputs, both diversity and stability had decreased, resulting in a more uniform species composition. The key environmental factors determining community diversities and stability include turbidity, pH, nitrate, and phosphate. The formation of eukaryotic planktonic microbial communities was predominantly influenced by the stochastic process, with dispersal limitation playing a key role. These discoveries could deepen our comprehension regarding the biogeographic distribution of microbial communities in emerging glacial lakes on the QTP and provide valuable insights into studying microbial ecological adaptations in the extreme environments and their response to climate change.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"286 ","pages":"Article 122785"},"PeriodicalIF":7.7,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
