We projected the avoided premature deaths related to different health endpoints (all-cause disease, cardiovascular disease, respiratory disease, ischemic heart disease and stroke) attributable to PM_2.5 constituents (BC, NH₄⁺, NO₃⁻, OM and SO₄²⁻) from 2022 to 2100 in China across different SSPs. The SSP1-2.6 scenario was expected to achieve approximately 380 thousand avoided premature deaths attributable to all PM_2.5 constituents. With age structure taken into account, the total avoided premature deaths were expected to increase by 37.5 %, 61.2 % and 80.5 % under SSP1-2.6, SSP2-4.5 and SSP5-8.5 scenarios, respectively. The total avoided premature deaths attributable to all-cause disease were expected to be mainly attributable to SO₄²⁻ due to a relatively large gap between SO₄²⁻ concentration in 2022 and the goals of SSPs as well as a higher β value, suggesting the priority of controls on residential coal combustion, power, and industrial boilers. The avoided premature deaths showed the highest sensitivity to BC and it is essential to prioritize the controls of residential coal combustion, residential biofuel combustion and off-road mobile source.

However, contaminants including Hg and persistent organic pollutants (POPs) in fish may pose a health concern for consumers. This study aimed to profile concentration patterns including interspecies and regional variations between Barents Sea and Norwegian Sea, and to explore correlations of nutrients and contaminants in five commercially important Arctic marine fish species using supervised machine learning applied to analytical data. These multivariate patterns were subsequently used as input in Monte Carlo simulations to assess the benefit and risk of fish consumption. Except for Atlantic mackerel, fish from the Barents Sea generally had lower concentrations of Hg and POPs than those from the Norwegian Sea, while nutrient concentrations were largely comparable across both regions. Fatty fish, especially Atlantic mackerel and herring had higher nutrient scores than lean fish. Consuming lean fish from 300 to 450 g per week did not entail risk of excessive Hg, dioxins and DL-PCBs exposure. Although weekly consumption of more than 190 g of mackerel or 130 g of herring from the Norwegian Sea, may exceed the tolerable weekly intake for dioxins and DL-PCBs (P &gt; 0.05), both species are excellent sources of EPA + DHA, Se and vitamin D.

This study examines the impact of chronic exposure to a cocktail of five pesticides (dieldrin, propiconazole, boscalid, bupirimate, and pendimethalin) with or without tributyltin (TBT) on glucose and lipid metabolism in mice, focusing on the role of the constitutive androstane receptor (CAR) and pregnane X receptor (PXR). TBT was included for its strong affinity for RXR, a key heterodimerization partner of CAR and PXR, to assess whether RXR activation modulates or amplifies the metabolic effects of pesticide exposure. Results showed that pesticide exposure at NOAEL levels altered CAR and PXR dependent metabolic pathways. CAR knockout mice exhibited reduced free fatty acids and fasting glycemia, while PXR activation led to lower peak glycemia in oral glucose tolerance tests. Transcriptomic analysis identified disrupted pathways linked to glucose uptake and insulin sensitivity. These findings suggest that low-dose pesticide exposure can subtly affect metabolism via nuclear receptor interactions. The inclusion of TBT emphases RXR’s role in metabolic regulation. Overall the study underscores the need to consider cocktail effects in risk assessment.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"667 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684751","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}

Recent overwhelming evidence suggests a possible association between fine particulate matter (PM_2.5) and bacterial AMR. However, the PM_2.5-AMR association was poorly understood. In this global analysis, we aim to provide in-depth and comprehensive insights into the PM_2.5-AMR association. Based on multiple global databases, two Bayesian multivariable models (negative binomial regression model and logistic regression model) with different lag time were used to estimate the association, quantify the lag-response effects, and identify potential effect modifiers. A total of 114,488 isolates with genome data, collected between 2000 and 2022 from 139 countries and regions, were examined. For every 10 μg/m³ increase in PM_2.5 exposure over the past 12 months, there was a corresponding 11.2 % increase (95 % CI: 10.6 %, 11.7 %) in the percentage of total resistance genes per isolate and an odds ratio of 1.18 (95 % CI: 1.17, 1.20) for carrying at least one resistance gene. There was a dose–response relationship between PM_2.5 level and AMR. The PM_2.5-AMR association might be highest at cumulative exposure during the past 12 months, and modified by bacterial species, sample sources, environmental factors, and other national-level economic, medical, and social factors. To summarize, we found significant associations between PM_2.5 exposure and AMR. Further studies are needed in phenotypic resistance data and possible intervention experiments in animals or humans to confirm these findings.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"13 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684752","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 results revealed the widespread presence of ARGs among culturable bacterial species, with potential pathogens carrying significantly more ARGs than non-pathogenic species. Temporal trend analysis revealed that only 11.0 % of bacterial species experienced an increase of more than one unit in ARG quantity and diversity over one century, with 83.3 % of them being potential pathogenic species. The temporal accumulation of ARGs in many potential pathogenic species is influenced by the abundance of mobile genetic elements, with several species also exhibiting temporal accumulation of plasmid-borne ARGs. Notably, <em>Shigella flexneri</em> and <em>Klebsiella pneumoniae</em> exhibited an accumulation of high-risk ARGs associated with at least five antibiotic types over at least 40 years. Furthermore, the distribution of ARG-carrying strains before the use of antibiotics revealed a wide range of bacterial species and antibiotic types for intrinsic resistance, including some synthetic antibiotics.
