The Sol-Char system demonstrated a superior life-cycle environmental performance, showing two to five times lower impacts in categories such as Climate Change (e.g., 127 kg CO₂-eq for the Sol-Char system while that 592 kg CO₂-eq for the AD system), Non-Renewable Energy Resources, Ionizing Radiation, Land Use, and Water Use. Both systems exhibited significant potential for resource recovery, with the Sol-Char system producing biochar and disinfected urine, and the AD system generating electricity, heat, and digestate.

'Sensitive' rivers display dramatic change via a positive feedback mechanism, exacerbating the change in the system. This paper investigates the geomorphic impacts of in-channel sand mining on the Gaula River, an ephemeral piedmont zone Himalayan River in northwest India. This river is characterized by high sediment flux from the tectonically active hinterland and flows primarily during the monsoon, making it suitable for sediment mining. Most geomorphological studies on sand mining in India have focused on peninsular rivers, leaving a knowledge gap in understanding the impacts on Himalayan systems. This study used satellite-based planform data (1976 to 2021) to develop morphometric indices coupled with the valley bottom confinement index, longitudinal profile and total stream power. Our results indicate that sand mining has altered flux boundary conditions, causing channel narrowing, incision, thalweg fixing, bed armouring, and a severe decline in geomorphic diversity. We have integrated the morphological response to sand mining to develop an evolutionary pathway of the Gaula River from barren conditions (1976) to underfit channel formation (2021).

Here, we employed ultra-high resolution mass spectrometry (UHRMS) to examine the molecular dynamics of DOM from terrestrial, marine and mixed sources during bio-incubation over weekly, monthly, and one year time spans. Using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), we classified DOM into three distinct categories (Consumed, Resistant and Product) based on their presence or absence at the start and end of the incubation. Our results show that molecular properties, such as hydrogen to carbon ratio (H/C), modified aromaticity index (AI<sub>mod</sub>), and nominal oxidation state of carbon (NOSC), strongly influence DOM lability and its biogeochemical cycling. Interestingly, Product formulas identified in the short-term incubations were often reclassified as Consumed formulas in longer-term incubations, underscoring the importance of incubation time in determining the persistence of DOM formulas. Further, we introduced a Change Ratio (CR) to identify formulas with significantly altered relative abundances. The molecular characteristics of these Increase or Decrease formulas exhibited notable differences, reinforcing their role in determining lability. In seawater samples, Decrease formulas were more abundant than Increase formulas, supporting the dilution hypothesis, which suggests low concentrations contribute to biological recalcitrance. However, the instability of relative abundance differences between Increase and Decrease formulas when CR thresholds were altered, coupled with the robustness of AI<sub>mod</sub> differences, highlights the dominance of molecular properties over concentration in determining DOM lability. Furthermore, the AI<sub>mod</sub> distribution of these Increase and Decrease formulas mirrored deep-enriched and surface-enriched formulas in the open ocean, validating our incubation results with field investigations.

Spat of P. canaliculus were held at a control temperature of 17 °C or a MHW temperature of 22 °C for the duration of the experiment and exposed to two environmentally relevant concentrations of the dinoflagellate A. pacificum for 4 days, followed by a recovery period of 4 days. The MHW temperature alone had no detrimental effect on mussel survival; however, exposure to A. pacificum at both temperatures led to reduced spat survival, especially at higher microalgal concentrations (< 90 % survival vs 100 % at the control temperature, no A. pacificum). The combination of both MHW temperature and A. pacificum exposure resulted in higher mortality than either stressor alone (as low as 59 % survival compared to 99 % at the MHW temperature alone). Spat exposed to A. pacificum alone showed up to a 4-fold reduction in byssal plaque production, crucial for spat attachment and therefore survival. Growth rate was >7.5 times slower, and there were increased histological alterations as compared to mussels in the control treatment. Similarly, spat exposed to A. pacificum showed significant changes in gene expression, particularly in pathways related to lipid metabolism and detoxification. Spat exposed to MHW temperatures alone had fewer differentially expressed genes, most being heat shock proteins. These findings emphasise the importance of understanding multi-stressor impacts in marine environments, particularly in the context of climate change and harmful algal blooms (HABs).</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"964 ","pages":"178590"},"PeriodicalIF":8.2,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027707","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}
