Still there is a lack of interdisciplinary studies observing the impact of noise annoyance on residents over an extended time frame. To understand annoying situations more precisely than previously possible, in a three-year investigation, we analyzed annoyance reports by residents with simultaneous measurements of acoustics, ground motions as well as meteorological and operational parameters. Ground motion and sound pressure levels could not explain noise annoyance, while there are hints to a connection with amplitude modulation and rotational speed. In a regression analysis only the combination of objective and subjective factors is able to predict annoyance sufficiently, with wind speed as the most relevant physical, and the perception of the planning process as the most relevant subjective factor. To meet concerns and better understand annoyance both aspects have to be considered: fairness in the planning process as well as the operational and environmental parameters influencing noise perception.</div></div>","PeriodicalId":308,"journal":{"name":"Environment International","volume":"202 ","pages":"Article 109614"},"PeriodicalIF":10.3,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305314","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}

The results demonstrated that PS-MPs were distributed widely in maternal mice, occurring mainly in the feces, colon, liver and mammary glands. Further experiments revealed that the gut and blood-milk barriers were disrupted, and pathological injury and inflammatory reactions were observed in the liver, gut, and mammary glands. Metabolomic and metagenome analysis indicated abnormalities in hepatic bile acid metabolism and significant alterations in the gut microbiota after exposure to PS-MPs. These alterations led to increased disruption of the intestine-liver axis. Notably, with fecal microbiota transplantation and antibiotic experiments, we observed that elimination of the intestinal microbiota reduced tissue inflammation and improved gut and blood-milk barrier leakage. These findings demonstrated that PS-MPs exaggerated intestine-liver axis disorders by inducing colonic injury, intestinal ecological dysregulation and abnormal hepatic bile acid metabolism.

Notably, the mechanisms driving ARG enrichment varied by NP type. PA-released NPs elevated reactive oxygen species levels in bacterial communities, facilitating horizontal gene transfer via MGEs, while PP- and PET-released NPs enhanced ARG enrichment through both horizontal gene transfer and shifts in bacterial community composition.

Most existing studies have been limited to specific regions or individual TPs, leaving the national risk characteristics of TPs unclear. To address these gaps, this study developed an environmental risk assessment database, covering 7,232 TPs in China. A combined analytic hierarchy process and entropy weight method was used to construct the risk assessment framework, which integrates inherent hazard levels, control mechanisms, environmental sensitivity, and disaster impacts. The national-scale evaluation revealed that 21.93% of the TPs in China, primarily located in southern China and the Qinling Mountains, face high risks. High inherent hazard levels, such as mineral species and operational status, are major contributors to these elevated environmental risks. Rainstorms and landslides have a compounded effect on the TPs’ environmental risks, exacerbating them, particularly in Yunnan and Hunan. In contrast, the spatial distribution of TPs does not coincide with areas of high peak ground acceleration, thereby reducing the potential impact of seismic activity on TPs. In summary, this study provides a scientific basis for the risk management and natural disasters adaptation of TPs in China.

This study provides a comprehensive assessment of the occurrence, environmental transport, influencing factors, removal efficiency, and human health risks of PFASs across UWS impacted by industrial activities. Regulatory restrictions on long-chain PFASs have led to their replacement with short-chain analogues, resulting in their dominance in effluents from manufacturing plant parks (MPPs), with concentrations ranging from 30.28 to 3738.51 ng/L (mean: 557.68 ± 1072.03 ng/L). Wastewater treatment plant (WWTP) serve as both sources and sinks of PFASs, with a negative average removal efficiency (–47.4 %) and an estimated annual discharge of 12.29 kg of PFASs into the environment. Downstream of WWTP, PFASs concentrations in rivers decrease exponentially due to dilution and sediment partitioning; however, short-chain PFASs persist over long distances due to their high aqueous mobility. While the detected PFAS levels in rivers pose low health risks to humans, they present low to medium ecological risks to aquatic organisms, particularly algae, invertebrates, and fish. Advanced statistical analyses using piecewise structural equation modeling (piecewiseSEM) and co-occurrence network analysis (CNA) identified key environmental drivers of PFASs behavior, including heavy metals (effect size: 0.70), nutrient levels (0.36), and physicochemical parameters (–0.52). Furthermore, drinking water treatment plants (DWTPs) demonstrated limited removal efficiency, with tap water concentrations ranging from 27.95 to 84.72 ng/L, exceeding the regulatory limits set by the US EPA (2022) (PFOA: 0.004 ng/L, PFOS: 0.02 ng/L) and Health Canada (Σ₂₅PFAS: 30 ng/L).
