This study evaluated ToBRFV as a human-specific microbial source tracking (MST) marker in Thailand, comparing its performance to crAssphage. Using qPCR assays, ToBRFV was detected in 62.5 % of building sewage samples (n = 16) and 100.0 % of wastewater treatment plant (WWTP) influent samples (n = 16). Notably, ToBRFV showed minimal cross-detection in non-human fecal samples (35 pooled samples), collected from cows, pigs, chickens, ducks, and goats, with only one detection in a pig fecal-source sample, demonstrating high specificity to human sewage. Concentrations in WWTP influent were significantly higher (mean: 5.19 ± 5.05; range: 3.96-5.62 log₁₀ copies/100 mL) than in building sewage (mean: 4.36 ± 4.40; range: 2.33-4.85 log₁₀ copies/100 mL) (p < 0.001). ToBRFV concentrations were significantly lower than crAssphage in building sewage but higher in WWTP influents. Additionally, ToBRFV and crAssphage exhibited moderate correlations in both building sewage and WWTP influent samples. These results suggest that ToBRFV could serve as a valuable MST marker for identifying human contamination in water bodies, complementing established markers. While ToBRFV's broader utility across diverse geographic regions remains to be fully validated, this study highlights its potential as a reliable indicator of human sewage in environmental surveillance.</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"963 ","pages":"178419"},"PeriodicalIF":8.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142997984","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 effect of artificial electromagnetic fields (EMFs) emitted from power lines, mobile phones, wireless equipment, and other devices on ageing and ageing-related diseases are receiving increasing attention. However, the information on the relationship between EMFs and ageing and ageing related susceptibility to EMFs is fragmentary, a review is needed. Only few studies directly investigate the effect of EMFs on ageing, and we reviewed the impact of EMFs on lifespan and cellular senescence to pry whether EMFs have an effect on ageing, and reviewed the age-dependent bioeffects and health impacts of EMFs to see whether ageing would affect biological susceptibility to EMFs. The results indicated that EMFs may have an effect on longevity and cellular senescence, but the results were inconsistent which may depend on EMF types (frequency, intensity, wave shape, etc.), species, and cell lines. Ageing has an impact on the biological or health effects of EMFs; however, the results differ depending on the EMF type and the endpoint or health outcome.

We used the drinking quality data uploaded to Spain's National Drinking Water Information System to gauge the state of the drinking water reporting in Spain, the differences between rural urban and rural areas in both quality and reporting and identify which variables at catchment level influence the probability of a municipality incurring in drinking water quality non-compliance. Random forest modeling was used to assess the drivers of non-compliance, including environmental (e.g., land cover, lithology, climate, state of the water supply source) and demographic (e.g., tap water expenditure, population density) data. We found that rural municipalities are more vulnerable both because of a lack of reporting but also because they have higher non-compliance rates for arsenic, microbiological and contaminants and nitrogen compounds (e.g. nitrate). We also found different spatial patterns of non-compliance according to each group of contaminants (e.g., microbiological violations are widespread in the northern half of Spain). The random forest model suggests that agriculture and confined livestock farming are behind nitrogen and microbiological non-compliances.

Leachate contents were initially filled with organic material and potassium that significantly declined with time, while Fe, Zn, and Cu concentrations increased significantly over time. Covers did not reduce leachate volume, but soil covers significantly reduced substances in the leachate. Corn stover barriers significantly reduced both leachate volume and substances in the leachate.

Qualitative results were confirmed using high-resolution mass spectrometry (HRMS) for those CECs without available standards. Ecotoxicological and human health risk assessments were performed for the quantified CECs. The analysis identified 35 suspect CECs (12 quantified with analytical standards), including parent compounds and metabolites of anti-inflammatories, antibiotics, antidepressants, sedatives, stimulants, and illicit drugs. High concentrations of these CECs were particularly evident near a Wastewater Treatment Plant (WWTP), where notable levels of compounds such as caffeine (4.02-15.03 ng L^-1), ciprofloxacin (6.05 ng L^-1), clindamycin (6.04-7.01 ng L^-1), and diclofenac (1.36-2.20 ng L^-1) were detected. Sediment samples exhibited the highest incidence of CECs, with caffeine reaching the highest concentration (55.89 μg kg^-1).

Human activities significantly alter the distribution of organic matter (OM) in rivers, thereby affecting the availability of DOM. However, the impact of total suspended solids (TSS) on DOM under anthropogenic influence remains insufficiently elucidated. This study employed Fourier transform ion cyclotron resonance mass spectrometry, DOC characterization, and incubation experiments to investigate how land use and degradation processes influence TSS-DOM transformation in rivers. Our findings revealed that geographical patterns cause significant variations in both DOM composition and TSS content. Anthropogenic impacts led to an increase in autochthonous TSS content and an enhanced relative intensity (RI) of nitrogen (N)- and sulfur (S)-containing compounds in riverine DOM. The presence of TSS increased the bioavailability of DOM from 29.97 % to 33.57 %. However, during both photodegradation and combined degradation processes, the presence of TSS reduced the bioavailability of DOM. The degradation rate constant (k) of DOM decreased as degradation time increased. The k values were significantly correlated with the CHO components in natural rivers and with N- and S-containing components in human-influenced rivers. The degradation rates of DOC under different land uses were 0.05 ± 0.04 d^-1, 0.07 ± 0.06 d^-1, and 0.08 ± 0.06 d^-1 in forested, urban, and cropland-influenced rivers, respectively. The content of aliphatic compounds and the number of CHOS molecules in TSS-containing water were higher than in TSS-free water during the combined process of photochemical and microbial degradation, while the saturation and aromaticity of the compounds were lower. The characteristics of autochthonous DOM were more pronounced under the influence of TSS photorespiration. During drinking water disinfection, these small molecules derived from autochthonous TSS may contribute to an increase in disinfection by-products (DBPs) in drinking water.

To fill this gap, this paper focuses on an Italian case study that quantifies the environmental impact of the traditional seed trays used worldwide for growing, transporting and transplanting tomato seedlings, proposing and evaluating two alternatives from a circular economy perspective. To do this, the Life Cycle Assessment (LCA) methodology was applied to the traditional and to two new reusable, recyclable, washable seed trays, comparing their entire life cycles. Primary data, provided by three manufacturers, two nurseries and four agricultural farms, were modelled using SimaPro software. Their environmental impact was calculated considering the potentials of global warming, eutrophication, acidification, abiotic depletion of elements and fossil fuels, ozone layer depletion, water scarcity and photochemical oxidation. Results show that, irrespective of the type of material used for the seed pots, the extraction and production phase of the materials is the most impactful in the life cycles. The proposed trays resulted more environmentally sustainable than the traditional non-reusable expanded polystyrene tray. The work also quantified the environmental benefit achieved with the weight reduction of the seed pots and their better handling by operators, which avoided breakages and losses. Furthermore, it is shown how the proposed reusable solutions can be greener, reducing the impacts up to a third in the case of global warming potential.
