This study aims to fill this critical research gap by conducting the first comprehensive biomonitoring assessment of DVAs in human urine, providing direct evidence of human exposure.

The potential health risks associated with cyanotoxins from contaminated fishponds are becoming a growing concern, as cyanotoxin production has steadily increased over time in these aquatic environments.

For detecting cyanotoxins in fish tissue utilizing the non-targeted approach, high-resolution MS/MS spectra data obtained from the analysis were converted to mzML format, analyzed with the Global Natural Product Social (GNPS) Library and CANOPUS annotations for LEVEL 3 metabolite identification, and visualized as a molecular network in Cytoscape. Regarding the targeted method, the toxin identification and quantification were achieved by comparing samples spiked with known concentrations of MC-RR and YR to an authentic toxin standard. The results of the target analysis showed that microcystin variant MC-RR was not detected in the fish tissue. The MC-YR variant was detected in the intestines and gills of <em>Clarias gariepinus</em> at concentrations of 13.2–10.6 μg/g and 1.5–13.9 μg/g, respectively.

There is currently a knowledge gap on the relationships between energy consumption structures (ECSs) and PAH contamination, especially in African countries. This study investigated the distribution, sources, and risks of 16 prioritized PAH compounds (Σ<sub>16</sub>PAHs) in Ethiopian soils, and explored the impact of ECSs on PAH contamination. The concentrations of Σ<sub>16</sub>PAHs ranged from 12.51 to 435.67 ng/g, descending across an urban-rural gradient. Based on diagnostic ratios and positive matrix factorization (PMF) model, biomass combustion was the most important source. By comparing the ECSs and PAH concentrations in African countries, it was found that differences in ECSs shaped the diverse patterns of sources and concentrations of PAHs in Africa. The results of incremental lifetime cancer risk assessment suggested PAHs posed a low risk to children, adolescents, and adults. The Ethiopian government has been making continuous efforts to develop cleaner energy and optimize ECSs to decrease soil PAH concentrations and reduce potential risks. This study will provide support for Ethiopia to improve energy structure management.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 2","pages":"Article 100461"},"PeriodicalIF":5.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To comprehensively and systematically understand the research hotspot and cutting-edge trends related to PFASs in the environmental field, a quantitative investigation was conducted based on 7735 PFAS-related articles extracted from the Web of Science Core Collection (WOSCC) from 2000 to 2023. The assessment involved trend of publication, prominent research contributors (countries, authors, and institutions) and influential journals. The results indicated a marked increase in the number of publications focused on environmentally-oriented PFASs since 2014, with these publications constituting approximately 83.89 % of the total body of literature on this topic. China and the USA emerged as the foremost contributors in this field. The preeminent journals included <em>Environmental Science &amp; Technology</em>, <em>Chemosphere</em>, and <em>Science of the Total Environment</em>. Keyword frequency, co-occurrence network, and burst analysis delineated PFASs' research in the environmental field primarily focused on environmental monitoring, toxic effects, and the ultimate destinations and degradation pathways of the PFASs. It is anticipated that future research will focus on investigating the toxic mechanisms of PFASs' impacts on human health and on developing techniques to remove PFASs from drinking water. This study provided a comprehensive overview of the extant literature, granting researchers an enriched understanding of PFASs’ research progress and offering valuable insights regarding potential avenues for further investigation.</div></div>","PeriodicalId":11539,"journal":{"name":"Emerging Contaminants","volume":"11 2","pages":"Article 100464"},"PeriodicalIF":5.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
