Hi-C sequencing has the advantage over other molecular approaches by directly associating genes conveying fitness to their host microbe, plus to their element type (in plasmids, phages, or within the core genome of its host microbe). Results from Hi-C analyses confirm results from more laborious approaches by showing that aminoglycoside resistance is disseminated by plasmids. Mercury resistance was found in Zoogloea bacteria. Resistance genes to quaternary ammonium compounds were found within bacteriophages. Results from this study provide proof-of-concept for the potential value of Hi-C metagenome sequencing in wastewater attribution studies by illustrating the breadth of information that can be obtained about the microbial community, the exchange of genes, and their interconnections.

The aim of this study was to provide objective data on this complex situation by integrating wastewater analysis, targeting benzoylecgonine (BE) and anhydroecgonine methyl ester (AEME) in 13 Swiss cities from 2021 to 2024, with street-level cocaine purity data obtained from near-infrared spectroscopy analyses, and survey data on user populations and administration routes used to compute a weighted BE excretion rate. Results highlighted strong weekly and spatial trends in BE loads and an overall increase in cocaine consumption, part of which could be attributed to the increase in cocaine purity. Unexpectedly, AEME loads did not increase; however, spatial trends were similar to those of BE, highlighting a correlation between AEME and BE loads. Overall, evolutions of crack cocaine use must be accounted for when monitoring general cocaine consumption through BE wastewater loads due to large differences in excretion rates. Thus, triangulation of multiple data sources allowed for a more comprehensive and nuanced understanding of the cocaine and crack cocaine situation in Switzerland, which is crucial to the implementation of tailored and efficient measures.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 2","pages":"204-220"},"PeriodicalIF":2.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147322152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 revealed that a significant proportion of the wells exceeded national and international permissible limits for these contaminants. To evaluate the potential impact on public health, three complementary indices were applied: the health risk index, the hazard quotient, and the water quality index. The integrated analysis demonstrated high consistency among the indices, particularly highlighting arsenic, iron, and nickel as critical contaminants. Multivariate statistical techniques further identified key patterns and groupings, revealing that contaminant levels are influenced by geological and hydrological factors such as well depth and flow rate. The integration of the results from these indices through multivariate statistical methods - specifically Principal Component Analysis (PCA) and cluster analysis - provided a valuable assessment of the concordance and divergences between the indices.

The probability of infection, the conventional metric in quantitative microbial risk assessment (QMRA), does not capture disease burdens caused by AMR, such as prolonged treatment and more severe illness. To address this, disability-adjusted life years (DALYs) were applied to estimate additional disease burdens due to AMR for diarrhea caused by Escherichia coli and impetigo caused by Staphylococcus aureus. Lake water used for irrigation was contaminated with sulfamethoxazole/trimethoprim (ST)- and tetracycline (TC)-resistant E. coli, linked to fecal pollution from livestock-related facilities, and amoxicillin (AMX)-resistant E. coli, which was widespread across the lake basin. QMRA revealed that the probabilities of infection from both E. coli and S. aureus exceeded the commonly accepted risk of 10-4. DALY-based estimates showed that AMR increased the annual disease burden by up to 4.2% compared with a non-AMR scenario, and potentially up to +100% under a high-AMR condition. These findings demonstrate that DALYs effectively quantify AMR-related health burdens associated with irrigation water containing directly or indirectly reused wastewater and support decision-making for AMR risk mitigation.","PeriodicalId":17436,"journal":{"name":"Journal of water and health","volume":"24 1","pages":"81-92"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146105999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Free-ion dosing achieved 99.8% disinfection of E. coli and ≥ 88.5% reduction of fungal species within 15 min at just 0.1 mg-Ag/L. E. coli exhibited the fastest Ag+ uptake and the highest inactivation rate (k15 min-1), followed by C. maltosa, A. brasiliensis, and M. luteus, reflecting increasing diffusion barriers.
