Hangzhou Bay (HZB) is particularly known for its high concentrations and rapid variations of total suspended matter (TSM) due to river input and tidal induced resuspending. Extreme TSM concentrations (C_TSM) of HZB usually exceed the application ranges of many existing remote sensing algorithms. In this study, a simple and efficient algorithm suitable for high dynamic C_TSM based on Rayleigh-corrected reflectance (ρ_rc) data from the Geostationary Ocean Color Imager (GOCI) was established. The parameters of this algorithm were determined by assembling a satellite-ground synchronous dataset from 2013 to 2020 using 3 buoys, ensuring that it was capable of monitoring C_TSM varying across four orders of magnitudes. Performance comparisons between recalibrated prevalence C_TSM retrieval algorithms based on surface water-leaving reflectance and the ρ_rc-based method in this study were also carried out. Results show that, the proposed algorithm in this study performed best with R² and mean absolute percentage error (MAPE) values of 0.75 and 45.41 %, respectively. When the proposed algorithm was applied on the GOCI data of 2019, although monthly changes of C_TSM in the HZB were observed in a pattern similar to that of NOAA C_TSM products, with high values occurring in the winter and lower values in the summer, the accuracy of daily results showed a significant improvement with R² of 0.65 versus 0.11, and MAPE of 38.86 % versus 75.06 %. And results derived using GOCI in this study can observe C_TSM fluctuations on small scales due to sediment resuspension during different tidal periods. Additionally, transferability of the proposed algorithm was examined with Landsat-8 and GOCI-II data. Overall, the findings of this study provided a concise and practical C_TSM algorithm to estimate more valid C_TSM at highly dynamic turbid coastal area.

Microbial communities play crucial roles in ecosystem functioning, yet their diversity and assembly in urban turfgrass systems remain underexplored. In 2017, microbial communities within 48 samples from managed turfgrass (home lawns, golf course fairways, and putting greens) and an unmanaged grass mixture in Madison, WI, USA were analyzed across leaf, thatch, rhizoplane, and rhizosphere habitats Intensive management, particularly in nitrogen-rich, sand-based putting greens, reduced fungal richness and diversity, whereas bacterial diversity patterns varied. Beta diversity analyses revealed distinct clustering: fungal communities differed most in unmanaged systems, while bacterial communities clustered within managed systems. Functional profiling demonstrated that bacterial communities maintained metabolic stability despite taxonomic shifts, while fungal communities showed dynamic functional responses to management. Furthermore, management practices also impacted microbial community assembly. Bacterial communities were predominantly shaped by neutral, stochastic processes, while fungal communities were more sensitive to management, showing deterministic, niche-based assembly and compositional shifts. These findings underscore the contrasting impacts of management on microbial communities and highlight the importance of sustainable turfgrass practices that balance plant health with microbial ecosystem functions. By linking microbial assembly processes to functional outcomes, this study provides insights for optimizing urban landscapes to enhance soil health and ecosystem resilience.

High-resolution datasets provide unique insights into extreme precipitation dynamics, capturing atmospheric, environmental, and anthropogenic influences missed by coarser data. Here, we use the 4 km CONUS404 dataset (1980–2021) to analyze trends in extreme hourly precipitation across the contiguous USA and adjacent regions. Using the 42 highest hourly precipitation values (HP42) from the 42-year dataset, we estimate regression slopes for their annual occurrence and intensity. ANOVA analysis examines the effects of elevation and land use on HP42 trends, while Multiple Linear Regression (MLR) assesses the effects of atmospheric drivers (dew point temperature, El Niño, La Niña, and North Atlantic Oscillation). Positive frequency slopes dominate central and northeastern regions, while decreases occur in the West and Southwest. Magnitude slopes are less spatially consistent but near zero in the high-elevation, arid regions of the West. Dew point temperature (TD) drives magnitude trends, while frequency trends are influenced by TD, La Niña, and the positive North Atlantic Oscillation index. Elevation significantly shapes frequency trends, with higher trends at lower and medium elevations (200–1000 m) and weaker trends above 1500 m. Land use impacts vary with elevation; Urban areas show decreasing frequency across several elevations, while natural land uses such as forests and wetlands often exhibit an increase or stabilization in precipitation trends at various elevations. Aggregating variables to coarser resolutions improves MLR model performance, unveiling significant factors by reducing noise. Hotspot analysis reveals that larger cities (e.g., New York, Los Angeles) have concentrated precipitation hotspots, while smaller cities (e.g., Memphis and Nashville) exhibit scattered trends. The overlap between frequency and magnitude clusters highlights shared drivers, suggesting increased vulnerability in peri-urban areas. These findings underscore the need for adaptive strategies addressing the complex interplay of urbanization, elevation, and climate factors.

Water availability in built environment, including heritage, plays a fundamental role in microbial colonization and subsequent biodeterioration. However, it is uncertain about the relationship between specific water characteristics and microbial development. Here, we applied water intrusion gravimetry (WIG) to quantify water distribution and then linked it to microbial growth by combining molecular biology techniques and petrophysical and mineralogical analyses. Porosity as well as capillary, gravitational, and saturation waters were distinctly increased in the monument stones compared to the adjacent quarry fresh sandstone. Archaea and bacteria, responsible for ammonia-oxidizing archaea (AOA), nitrite-oxidizing bacteria (NOB) and Comammox species were enriched with increasing capillary water mainly, and intriguingly, the copies of bacterial 16S rRNA and Comammox amoA genes were positively correlated with capillary water significantly (r² = 0.73, p < 0.001) and inversely correlated with gravitational water (r² = 0.60, p < 0.01). An important finding for the enlargement of the pores in the monuments was the dissolution of calcite and oxides from the sandstone by HNO₃ erosion simulation. Collectively, these findings advance our understanding of water status in the pores of monuments and provide new insights into mechanisms of biofilm formation and preventive measures against microbial issues and biodeterioration.

The serotypes of Enterovirus A (EVA) causing hand, foot, and mouth disease (HFMD) exhibit cyclical dominance, with the dominant serotypes being EVA71, Coxsackievirus A type 6 (CVA6), CVA10, and CVA16. In this study, a quadruplex digital polymerase chain reaction (dPCR) assay was developed for serotype-level monitoring in wastewater surveillance for HFMD. The quadruplex dPCR assay performance was comparable to that of the singleplex assays. Grab influent samples (n = 122) were collected weekly from a wastewater treatment plant in Yamanashi Prefecture, Japan, from March 2022 to July 2024. The dPCR results revealed that CVA6 had a lower prevalence in 2023 than in 2022 and 2024, while the detection ratio of EVA71 was significantly higher in 2023 than in 2022 (Chi-square test, P < 0.05). Triangulation of these results with a clinical report indicated the dominance of CVA6 in 2022 and 2024, but not in 2023, while EVA71 was found to be dominant in 2023. Secondary data revealed significantly higher HFMD cases in the catchment in the years when CVA6 was dominant and significantly lower in the years when EVA71 was dominant. The comparative analysis revealed a stronger correlation between CVA6 RNA concentrations and HFMD cases (r = 0.83) than that between a broad range of Enteroviruses, Pan-Enterovirus RNA concentrations (r = 0.47). Thus, serotype-level monitoring, particularly through quadruplex dPCR, provides valuable insights into EVA serotype dynamics, accurately reflects HFMD trends, and supports the monitoring of the cyclical patterns of EVA serotypes.

Nature-based solutions (NBS) such as biofiltration are an efficient, eco-friendly, and economical alternative for wastewater treatment under decentralized contexts. However, the influence on removing emerging contaminants (pharmaceuticals and personal care products or PPCPs), considering different typologies and seasonality fate, has been little studied. In this work, four lab-scale biofiltration typologies (BM: Biofilter + microorganisms, BEM: Biofilter + earthworms + microorganisms, BH: Biofilter + microorganisms + plants + earthworms or Biofilter hybrid, BPM: Biofilter + plants + microorganisms) were monitored seasonally (April–December, 250 days), being fed with rural domestic wastewater. Zantedeschia aethiopica (L.) and Eisenia foetida Savigny were used as biotic components, interacting with organic support components (hazelnut shells and sawdust) for removal of organic matter, nutrients, and 4 PPCPs (caffeine, ibuprofen, losartan, and triclosan). The mass balance of PPCPs was carried out considering the input (influent), output (effluent), support (soil), and plant (root and stem/leaf). The results showed that the different evaluated typologies removed close to 100 % COD, up to 89 %

{NH}_{4}^{+} - N

, and up to 99 % coliforms. Meanwhile, caffeine, ibuprofen, losartan, and triclosan were removed between 34 and 100 %. Seasonality or biofiltration typology was non-significantly influential (p > 0.05). However, biofilter hybrid and the warm season were the most efficient for removing organic matter, nutrients, coliforms, and PPCPs. The PPCPs' fate was plants/substrate/effluent with values up to 36, 95, and 64 %, respectively. The effluent was caffeine's main fate. Substrate was the main fate of ibuprofen, losartan, and triclosan. Plants uptake caffeine as a carbon source.

Fenoxycarb, a carbamate insecticide, functions as a juvenile hormone agonist to inhibit pests, and its detection in aquatic environments is concerning because of its widespread application. These concerns have led to ecotoxicological studies on aquatic crustaceans; however, research on the effects of fenoxycarb on the developmental processes of organisms is limited. In the present study, the deleterious effects of fenoxycarb on zebrafish development and the related cellular mechanisms mediating this toxicity were addressed. Exposure to sublethal concentrations of fenoxycarb (0, 0.5, 1, and 2 mg/L) resulted in morphological defects in zebrafish larvae, particularly in the heart region, eyes, and body length. These defects were accompanied by an increase in the number of apoptotic cells and the upregulation of related gene expression. Moreover, fenoxycarb increased ROS production and the number of macrophages, and altered the expression of immune-related genes, thereby inducing inflammation. These results revealed various abnormalities in the heart, vasculature, liver, and pancreas, as confirmed by transgenic models, such as cmlc2:DsRed, fli1a:EGFP, and fabp10a:DsRed;elastase:GFP. These developmental impairments were associated with the altered expression levels of genes involved in the development and function of each organ. These results suggest that fenoxycarb can affect multiple organs through excessive inflammation during development and highlight its potent toxic effects on other non-target organisms.

These results revealed various abnormalities in the heart, vasculature, liver, and pancreas, as confirmed by transgenic models, such as <em>cmlc2:DsRed</em>, <em>fli1a:EGFP</em>, and <em>fabp10a:DsRed;elastase:GFP</em>. These developmental impairments were associated with the altered expression levels of genes involved in the development and function of each organ. These results suggest that fenoxycarb can affect multiple organs through excessive inflammation during development and highlight its potent toxic effects on other non-target organisms.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"969 ","pages":"Article 178957"},"PeriodicalIF":8.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488815","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}

Constructed wetlands (CWs) are recognised as effective wastewater purification systems for the removal of contaminants, particularly nitrogen (N). However, the performance of a CW in N removal relies on complex biogeochemical interactions within and between various compartments. We assessed the concentrations and isotopic compositions of multiple N and C species in the water column, sediment, plants and soil in the riparian and adjacent terrestrial zones within a CW in South Australia. The major source of N supplied to the wetland is domestic effluent delivered via a municipal wastewater treatment plant resulting in high NH₄⁺ concentrations (54 mg L⁻¹) at the inlet of the wetland. The decrease in NH₄⁺ and increase in NO₃⁻ concentrations, coupled with an increase in δ¹⁵N-NH₄ in the water along the flow path of the wetland, strongly indicates the significance of nitrification and assimilation processes. We also observed an increase in δ¹⁵N-NO₃⁻_, however, the lack of increase in δ¹⁸O-NO₃⁻ suggested denitrification was either not a prominent process, or the δ¹⁸O-NO₃⁻ signature was masked by the extent of nitrification. There was evidence of an influence of the wastewater on the plants in the riparian zone as their δ¹⁵N increased along the flow path, unlike the adjacent terrestrial plants. Similarly, this occurred with suspended solids, indicating progressive plant and algal assimilation of N in the CW. Further research is required to account for changes with seasonality and sediment processes and interactions.

A two-year field experiment was conducted to compare the impact of conventional tillage (CT) and non-tillage (NT) on the mobility in two soils (S1 and S2) of the herbicides S-metolachlor (SMOC), foramsulfuron (FORAM), and thiencarbazone-methyl (TCM), and the formation of their main metabolites. Herbicide and metabolite distribution through the soil profiles (0–50 cm) was determined over two maize cycles. After the first application, the mobility of SMOC and TCM was similar under CT conditions, with higher concentrations in S2 + CT topsoil than in S1 + CT due to the higher organic carbon content in S2 and its retention ability, while both herbicides were detected in the entire S1 + CT profile over time. Under NT management, partial interception by the mulch during application reduced the amount of herbicides that initially reached the topsoil, modifying their mobility dynamics. SMOC and TCM properties facilitated their transport through the soil profile, favoured by the irrigation applied shortly after their application. The total SMOC and TCM balance in S1 and S2 profiles revealed possible leaching below 50 cm, especially in soils+CT. However, the simultaneous degradation of SMOC and TCM might also occur on the mulch and/or in soil profiles, as indicated by the continuous detection of two SMOC metabolites (ethane sulfonic acid, SMOC-ESA, and oxanilic acid, SMOC-OA) and one TCM metabolite (thiencarbazone, TCM-MET1) throughout the soil profile in all the treatments assayed. FORAM dissipated faster than SMOC and TCM in all the treatments, with a total balance in all the soil profiles <40 % after 13 days. The high water solubility and polarity of FORAM might have enhanced its leaching, although its degradation to its two main metabolites was also observed in all cases. The mobility dynamics of the three herbicides in the second experimental period were similar for both soils under CT, but differed in soils under NT compared to the first application, with higher interception by the greater amount of mulch on the soil surface in the second year.
