Understanding these impacts on emergency healthcare utilization is critical for effective resource planning and public health preparedness. This systematic literature review, conducted following PRISMA guidelines, examines the influence of extreme temperature events on ED admissions. A comprehensive database search from 2012 to 2024 identified 42 relevant studies and two of them considered both heatwaves, coldwaves or temperature variation: 22 on heatwaves, 6 on cold waves, and 16 on temperature variations. Heatwaves are consistently associated with increased ED admissions for various health conditions, including orthopaedic trauma and exacerbations of chronic illnesses. At the same time, cold waves are linked primarily to respiratory and cardiovascular issues, often with delayed effects. Several studies indicate that older adults, those with pre-existing conditions, and socioeconomically disadvantaged populations may face disproportionately severe consequences during these events. Socio-demographic factors, including age, gender, socioeconomic status, and geographic location, significantly influence these outcomes. These findings highlight the differential impacts of extreme temperature events on ED utilization, emphasizing the importance of preparing EDs for post-event surges and advocating for coordinated emergency planning and targeted public health interventions to manage these challenges effectively.</div></div><div><h3>Implications for public health</h3><div>The findings of this study provide actionable insights for clinicians, academics, and policymakers to understand better the impact of extreme temperature events on emergency departments.

Simultaneously, the urgent need to address plastic waste, particularly polyvinyl chloride (PVC), has become a global concern. In this work, a strategy for Li extraction through synergetic pyrolysis of LiMn₂O₄ cathode materials (LMO) and PVC is proposed. Under optimal conditions, the recovery rates of lithium and manganese reached 99.89 % and 0.02 %, respectively, demonstrating efficient separation of these elements. Temperature was found to play a critical role in the leaching rates of lithium and manganese by promoting the decomposition and reduction of LMO. Additionally, kinetic analysis shows that the activation energy (<em>E_a</em>) of the synergetic pyrolysis is 139.60 KJ/mol, and the pyrolysis mechanism satisfies third-order reaction process. Eventually, the proposed mechanism involves the synergistic effects of chlorination and reduction reactions. First, HCl is generated by PVC pyrolysis under the catalytic effect of LMO. Then, the chlorination of HCl with LMO occurs by capturing structural oxygen and generating LiCl and MnCl₂. Simultaneously, the reduction reaction between the reducing species generated by PVC pyrolysis and LMO occurs to form Li₂O and MnO, ultimately enabling the separation of lithium and manganese. Overall, this paper presents a novel approach for future applications by providing a theoretical basis for selective Li extraction.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"198 ","pages":"Pages 95-105"},"PeriodicalIF":7.1,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526617","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 investigates the ecological carrying capacity of sports tourism in Rizhao City, China, using a \"carrier-load\" integration perspective and a multi-scale spatiotemporal approach. The research divides Rizhao City into two distinct regions: the Mountainous Hills Sports Tourism Region (MSTR) and the Coastal Plains Sports Tourism Region (CSTR). By analyzing 16 key indicators, including vegetation cover, water conservation, sports tourism revenue, and carbon footprint, the study evaluates the dynamic interplay between ecological carriers (natural resources) and tourism loads (human activities). The results reveal significant spatial and temporal variations in Ecological Carrying Capacity of Sports Tourism (STECC). The MSTR exhibits a stable STECC index around 1.6, indicating strong ecological resilience but with signs of slight overloading during peak seasons. In contrast, the CSTR shows a higher STECC index ranging from 2.6 to 2.94, reflecting severe ecological overloading due to intense coastal tourism activities, particularly in summer. The study highlights the critical need for targeted ecological protection measures in the CSTR, such as controlling tourist numbers and enhancing ecological restoration, while leveraging the MSTR's potential to alleviate pressure on the coastal region. These findings provide a scientific basis for sustainable sports tourism development, emphasizing the importance of balancing ecological preservation with tourism growth.

After 40 months, different soil physico-chemical properties, total nutrient (organic carbon –C–, nitrogen –N– and phosphorus –P–) and labile P and N fractions were analysed together with bacterial functional groups catalysing major steps in P (<em>phoD</em>, <em>appA</em>, <em>phnX, pstS</em>) and N turnover (<em>chiA</em>, archaeal <em>amoA</em>, bacterial <em>amoA</em>, <em>nirS</em>, <em>nirK</em>, <em>nosZ, nifH</em>), as well as total bacterial biomass.

It is characterized by complex redox gradients, with groundwater-mediated inflow of reduced substances affecting the oxygen budget of stream water. In this study, we have experimentally simulated the inflow of Fe(II)-rich groundwater into the open stream water of a flume system to quantify its effect on dissolved oxygen concentration in both the stream water and the hyporheic zone. The experimental setup consisted of 12 flumes, half used for input of groundwater augmented with Fe(II), while the other half served as a control. We studied the effects of coarse (6% fine sediment content) sediment vs. fine (28 % fine sediment content) sediment as well as and moderate (3 L s^-1) vs. low (0.5 L s-1) flow rate in a fully-crossed, 3-way-replicated design. Weekly sampling campaigns were performed to analyze Fe(II), Fe(III), DOC, and dissolved oxygen (DO) concentrations in the pore water (hyporheic zone) and in the open water over five consecutive weeks. Our results indicate that Fe(II) inflow substantially decreased DO concentrations in both the pore and open waters. Oxygen uptake rates increased from 7.4 up to 8.6 g O₂ m^-2 d^-1 at a moderate flow rate and from 1.7 to 1.9 g O₂ m^-2 d^-1 at a low flow rate. This corresponds to a contribution of the Fe(II) input to the overall oxygen uptake rate in the flumes of 21 and 17%, respectively. Treatment with FeCl₂ also led to a substantial increase in DOC from ∼ 55 mg L^-1 in the control flumes to &gt; 60 mg L^-1 suggesting a linkage between Fe(II) mobilization and the occurrence of DOC. In conclusion, this study highlights the need to consider the effects of hyporheic and riparian redox processes and subsequent inflow of Fe(II) into streams on the oxygen budget and the health of stream ecosystems.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"5 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Our findings demonstrate that Bermudagrass significantly improved soil quality and multifunctionality compared to adjacent bare tailings. Soil improvements included increases in organic matter (107%), total and available nitrogen (50% and 110%, respectively), available phosphorus (170%), and soil enzyme activities, including β-glucosidase (170%), sucrase (1729%), alkaline phosphatase (3722%), and acid phosphatase (168%). The reclamation process also promoted microbial community succession, altering community composition, improving microbial diversity, and enhancing bacterial biomass from (0.89 ± 0.54) × 10¹⁵ to (9.06 ± 3.25) × 10¹⁵ copies/g in rhizosphere soils. Greenhouse experiments further confirmed Bermudagrass's resilience to cadmium (Cd), with both mining and non-mining ecotypes thriving in tailing soils and Cd²⁺ hydroponic solutions (up to 44.5 μM) without evident phytotoxicity. Bermudagrass roots exhibited exceptional Cd accumulation (bioconcentration factor: 181–1006) while minimizing Cd translocation to shoots (translocation factor: &lt;0.13). Inoculation with <em>Funneliformis mosseae</em>, a restored root-mutually symbiotic fungus, further mitigated Cd-induced phytotoxicity and enhanced plant growth. These findings highlight Bermudagrass as a promising pioneer species for phytostabilization in severely contaminated mining environments, with its rhizosphere microbiome playing a critical role in facilitating ecosystem restoration.

In this study, we developed a mesoporous network-structured spherical La-based hydrogel for dual nitrogen and phosphorus control. The hydrogel framework, cross-linked by sodium alginate and lanthanum, encapsulates free La³⁺. The preparation process avoids high-energy techniques and produces no waste, with recyclable reagents. Through adsorption tests, cryo-electron microscopy, and surface area and pore size analysis, we found that the mesoporous structure shields internal free La³⁺, preventing rapid release and minimizing waste of La³⁺. The cross-linked La³⁺ in the spherical framework is released by microbial degradation of the polysaccharide skeleton, inducing anaerobic conditions in the sediment and passivating soluble reactive phosphorus (SRP) simultaneously. The G-units in sodium alginate act as a carbon source, enhancing sulfur-nitrogen cycle coupling, denitrification and reducing NO₃⁻ release. Three-month laboratory simulations and nine-month field <em>in-situ</em> experiments demonstrated significant nutrient control. In the field trials, one month after application, the SRP concentration in the water column decreased to 0.006 mg/L (a 75% reduction), and the NO₃⁻ concentration decreased to 0.15 mg/L (an 87.5% reduction), with greatly improved water transparency and no cyanobacterial blooms.

A total of 180 serum samples were analyzed for metabolomic profiles using liquid chromatography-mass spectrometry. The associations between personal metal exposure, metabolite levels, and indicators of cardiovascular injury were analyzed by linear mixed-effects modeling (LEM) and Bayesian kernel machine regression (BKMR). Metabolomic analyses showed 79 metabolites in the serum of healthy adults changed significantly between seasons and all metabolites were strongly associated with toxic metals. Additionally, differential metabolites were enriched in seven metabolic pathways and activated by metal exposure, such as Butanoate metabolism and Linoleic acid metabolism. BKMR model interpreted that the overall effect of metals mixture was negatively associated with Capryloyl glycine and Sphinganine and Sb mainly contributed to the effect. The results of mediation analysis revealed that the association between V and VEGF was mediated by Diethylhexyl with a partial proportion of 13.4%. Furthermore, the result also found the association between CerP(d18:1/26:1(17Z)) and ET-1 was mediated by TGFβ1 with a proportion of 53.4%.
