Particulate matter ≤2.5 μm (PM_2.5) air pollution, including ambient PM_2.5 and household PM_2.5, is a significant risk factor for this disease. However, an updated and comprehensive assessment of lung cancer burden attributable to PM_2.5 remains limited. We evaluated the deaths, disability-adjusted life years (DALYs), age-standardized mortality rate (ASMR), and age-standardized DALY rate (ASDR) of lung cancer attributable to total, ambient, and household PM_2.5 at the global, regional, and national levels, using the Global Burden of Disease (GBD) 1990–2021 data. The estimated annual percentage change (EAPC) was used to analyze the trends in the ASMR and ASDR. Age, sex, and the socio-demographic index (SDI) were considered. In 2021, PM_2.5 exposure accounted for approximately 0.37 million deaths and 8.9 million DALYs of lung cancer. East Asia had the highest lung cancer burden attributable to total PM_2.5. From 1990 to 2021, the global lung cancer burden attributable to both total PM_2.5 and household PM_2.5 decreased, whereas that attributable to ambient PM_2.5 increased. Furthermore, the ASDR/ASMR attributable to ambient PM_2.5 were positively related to the SDI, whereas those attributable to household PM_2.5 were negatively related. Global lung cancer deaths and DALYs attributable to ambient PM_2.5 are expected to rise continuously up to 2045. In summary, this study emphasizes the need for strengthened, region-tailored air quality policies to reduce the lung cancer burden attributable to PM_2.5 and to narrow regional inequalities.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"390 ","pages":"Article 126216"},"PeriodicalIF":8.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365089","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}

A first period, comprising approximately the years 1940 to 1975, where the drought years are quite anomalous with respect to average years, and a second period, from approximately 1975 onwards, where the comparison of CNs reveals a clear trend to drier years, with lesser differences with drought years.

Here, the <em>n</em>-alkane diagnostic pattern, δ¹³C_{<em>n</em>-alk} end-member model, ecological data, and the historical OM input, associated with the ecosystem evolutionary processes were investigated. The results show the long-term ecological evolution under climate warming and anthropogenic interferences promoted the organic C (OC) and nitrogen (ON) burial in the sediments. The <em>n</em>-alkane distribution pattern, diagnostic proxies, and δ¹³C_{<em>n</em>-alk} signatures supported the degradation of the ecosystem from macrophyte-dominated (before the 1970s) to mixed (1980s–1990s) and then to algae-dominated (after 2000s) ecosystem. The conversion between aquatic macrophytes and prevailing algae and intensive anthropogenic activities increased OC and ON burial by 3.43 and 3.56 folds, respectively. The differential input of nutrients exacerbated the imbalance of N and phosphorus and stimulated the expansion of algae. Although exogenous OM inputs from terrestrial vascular plants increased rapidly with anthropogenic interference, the LMW-derived <em>n</em>-alkanes and lower C/N ratio and TAR also provide evidence for the predominance of typical endogenous OM input. Meanwhile, an explanation of the photosynthesis pathway from δ¹³C_{<em>n</em>-alk} of long-chain <em>n</em>-alkanes indicated that C₃ plants in the lake ecosystem were dominant with more than 70 % of the total over the past century.

Secondly, the influence of soil physicochemical properties on the remediation effect of PAHs-contaminated soil was mainly summarized. Next, the catalytic degradation mechanism of PAHs was proposed based on active species identification, density functional theory (DFT) simulation, and intermediate product detection. Finally, future research directions for the remediation of PAHs-contaminated soils were proposed, including the design of efficient and environmentally friendly oxidants, persulfate catalysts, and slow-release persulfates, the construction of predictive modeling regarding soil remediation process parameters, the long-term monitoring of physical and chemical properties and reuse characteristics of remediated soils, as well as the focus and utilization of efficient and safe remediation methods. These approaches were mechanochemical activation, micro- and nano-bubble activation, bioremediation, electrokinetic remediation, etc. Notably, the coupling use of surfactants that are environmentally friendly and recyclable in the remediation process was also critical.

In response to sustainable development, this paper presents a multi-objective model integrating economic, environmental, and social dimensions to design a sustainable closed-loop supply chain network for the electric vehicle battery industry. In addition, a resilient strategy is applied, and a Fuzzy Robust Stochastic model incorporating Conditional Value at Risk (FRS-CVaR) is proposed to enhance the overall resilience and robustness of the supply chain network. To solve the proposed model, an improved NSGA-II is developed by applying an initialization strategy to enhance the quality of initial solutions, incorporating an adaptive evolutionary strategy to accelerate convergence while maintaining population diversity, and use elite retention strategy to avoid inferior regions. The deterministic model and the FRS-CVaR model are solved using Gurobi, NSGA-II, and the improved NSGA-II, respectively. The improved NSGA-II algorithm achieves a 40 % and 22 % increase in the Hypervolume (HV) metric, while Spacing values are reduced by 27 % and 52 %, respectively, compared to NSGA-II. The results demonstrate that the improved NSGA-II converges faster and exhibits superior performance. Study findings show that the proposed model can be applied as an efficient tool for designing a sustainable, robust supply chain network based on decision makers' preferences.

This study examines the environmental implications of extensive and intensive sugar beet production systems in Hamadan Province, Iran, with a focus on the role of energy intensity. A random sample of 88 sugar beet farms was selected for data collection. To differentiate between extensive and intensive sugar beet farms, a c-means fuzzy clustering model was employed to cluster farms based on their energy inputs. The extensive farming system (Cluster I) exhibited lower energy consumption, higher energy efficiency, and reduced environmental impacts compared to the intensive farming system (Cluster II). These results highlight the potential of adopting more sustainable practices, such as improved irrigation management and reduced reliance on chemical inputs, to enhance the environmental performance of sugar beet production. This study provides valuable insights into the energy and environmental implications of sugar beet cultivation in Iran. The findings underscore the need for a shift towards more sustainable farming practices to mitigate environmental impacts and ensure the long-term viability of the agricultural sector.
