In South America, studies on POPs in wild bees, like <i>Bombus pauloensis</i>, a continentally widespread bumblebee, are lacking, and information on its health is limited. This study assessed, by GC-ECD, PCBs and PBDEs levels in <i>B. pauloensis</i>, flowers and soils from fields located at different distances from urban activities: PU and LF, two peri-urban fields near the local industrial park, with LF also next to an overloaded solid waste landfill, and RU, a rural field. For all matrices, the peri-urban fields registered significant higher pollutant levels compared to RU, especially in workers, where LF showed the highest ∑PCBs and ∑PBDEs levels (21.09 ± 2.57 and 10.29 ± 0.37 ng/g, respectively). In males, PU and LF showed the highest nominal ∑PCBs (PU; 24.97 ± 1.03 ng/g) and ∑PBDE (LF; 10.39 ± 0.77 ng/g) concentrations, which confirms the influence of the landfill. Across matrices, lighter PCB congeners dominated, possibly explained by the past use of PCB mixtures and atmospheric transport, and a biomagnification pattern was observed. PCB concentrations were similar to those proven to cause sublethal effects in bees, and males showed significantly higher POP levels than workers. Thus, drivers and population effects were discussed. This may be one of the first studies of industrial POPs in wild bees in South America, emphasizing the need to look beyond insecticides and unique castes in environmental exposure studies.\u0000</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"32 14","pages":"9017 - 9029"},"PeriodicalIF":5.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 imposes unnecessary compliance burdens, reinforces public misconceptions, and fails to reflect the low environmental impact of NPPs. While the dual-agency model provides specialized oversight, it is in contrast with the global trend of regulatory streamlining. To align with international best practices, we propose (i) replacing the color-coded classification with an oversight-based nomenclature inspired by France’s regulatory trend, (ii) treating NPPs as a distinct category within pollution frameworks while maintaining compliance with nuclear and environmental regulations, and (iii) adopting a single-agency oversight model to unify pollutant limits, in line with the US trend.

Novel surfactant formulations, including biosurfactants and hybrid systems, have shown improved recovery efficiency and environmental sustainability. Surfactant-polymer mixtures offer synergistic effects that enhance performance across various reservoir conditions. Concurrently, advancements in nanoparticle technology, such as green nanotechnology and improved formulations, have enhanced the stability, dispersion, and functionality of nanoparticles in EOR processes. Critical factors such as nanoparticle size, concentration, and surface modifications play pivotal roles in optimizing oil recovery efficiency. However, significant challenges persist, particularly surfactant adsorption onto rock surfaces and nanoparticle agglomeration, which reduce the overall effectiveness of these techniques. Addressing these limitations requires strategies such as surface modification and advanced delivery mechanisms. Additionally, economic and environmental concerns remain key barriers to large-scale implementation, underscoring the importance of sustainable and cost-effective solutions. A critical gap in the research is the lack of large-scale field studies and long-term monitoring, which are essential for validating laboratory findings and optimizing these technologies for real-world applications. With increasing focus on sustainability, future research is expected to prioritize eco-friendly materials and methods. Integrating surfactant and nanoparticle-based EOR with other recovery techniques, such as thermal and gas injection, holds potential for maximizing oil recovery.

Its implications extend to India’s natural resources and agricultural sectors. This research rigorously examines the long-term spatial and temporal changes in rainfall patterns in Bihar, India, utilising high-resolution daily rainfall gridded data from the India Meteorological Department, which includes data from a total of 133 grid points. Coefficient variation analysis reveals low monsoon and annual rainfall variability but substantial variations in the pre-monsoon, post-monsoon, and winter seasons, indicating pronounced changes in Bihar’s precipitation patterns. Trend analysis offers nuanced insights, using Modified Mann–Kendall (MMK) and Innovative Trend Analysis (ITA). Pre-monsoon rainfall exhibits a statistically significant increasing trend (Z = 3.252), with an annual increment of 0.748 mm. In contrast, a persistent decline characterises monsoon (Z =  − 0.598), post-monsoon (Z =  − 0.112), winter (Z =  − 0.297), and annual (Z =  − 0.219) precipitation patterns over 72 years.

The AMF communities at moderately contaminated and uncontaminated areas showed a similar structure, with <i>Rhizoglomus</i> as the dominant genus. Species such as <i>Palaeospora spainiae</i>, <i>Rhizoglomus silesianum</i>, <i>Septoglomus</i> sp., <i>Septoglomus nigrum</i>, <i>Ambispora</i> sp., <i>Claroideoglomus etunicatum</i> and <i>Diversispora</i> sp3. were identified exclusively in the roots of <i>Miscanthus</i> × <i>giganteus</i> and <i>Spartina pectinata</i> grown in contaminated areas. They could potentially be used to support phytostabilisation of areas contaminated with Pb, Cd and Zn, but further studies are needed.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"32 14","pages":"8943 - 8958"},"PeriodicalIF":5.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
