The phase having the greatest environmental impact is the drying phase, since it requires a significant input of energy and time. This phase is essential for many valorisation strategies, as it facilitates the storage and transportation of citrus waste. To gain insight into the Life Cycle Assessment (LCA) of drying techniques, a Systematic Literature Review (SLR) was conducted in this study based on PRISMA statement. Eleven articles were reviewed, to understand the energy requirements and the environmental impacts associated with the process, along with the economical profitability. To that end, attention was focussed upon single- and multi-indicator LCAs. Results from the SLR showed that the drying phase makes citrus waste low valuable for energy valorisation employing gasification, with heat generation efficiency between 21 % and 25 %, or to produce biodiesel, with the impact greater than in conventional diesel usage for a vehicle. Sustainable practices in which the drying phase has a lesser impact include incineration and animal feed. In both cases, dehydration was performed with an industrial direct kiln, requiring the consumption of fossil fuels. Indeed, citrus waste has low thermal potential (low heating value&lt;4 MJ*kg⁻¹), and its use for thermal energy would result in lower environmental performance than natural gas. Moreover, using citrus waste as a feed additive for livestock is feasible, provided that the distance between the livestock and citrus processing facilities is assessed for sustainability.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"974 ","pages":"Article 179219"},"PeriodicalIF":8.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

None of the tested nanomaterials significantly altered CYP expression, except for nGO, where a slight increase in CYP3A4 protein expression was observed.

Soil and plant samples were collected at intervals from 0 to 300 m away from the railway to assess the concentrations of nickel (Ni), cadmium (Cd), lead (Pb), and zinc (Zn). The findings indicated that heavy metal concentrations decreased with increasing distance from the railway, with surface soils showing higher contamination than subsurface soils.

This study examines the effects of transitioning from extensive pastures to silvopastoral systems on soil ecosystem services (SES) in the Colombian Amazon. We identified sensitive soil indicators to monitor SES changes in response to livestock management, and synergies and tradeoffs between them. Soil samples were collected from three locations to a depth of 30 cm across three land uses: traditional pastures, 15-years-old silvopastoral systems implemented on former pastures, and secondary vegetation. We assessed five critical soil-related ecosystem services: support for plant growth, carbon storage, nutrient cycling, erosion control, and water regulation and aeration. Our findings reveal significant enhancements in multiple soil ecosystem services in silvopastoral systems, with increases of 32 % in plant growth support, 34 % in nutrient cycling, and 16 % in erosion control compared to traditional pastures. Although soil carbon (C) storage showed no significant differences between pastures and silvopastoral systems, both systems exhibited values 16 % higher than secondary vegetation. A positive interconnection among carbon storage, nutrient cycling, and erosion control services was revealed, highlighting them as major drivers of synergies. Seven soil properties were identified as sensitive indicators of changes in land management, which may serve as key proxy for monitoring soil ecosystem services: i) soil organic carbon, ii) pH, iii) soil base saturation, iv) copper, v) magnesium, vi) zinc, and vii) aluminum. These results highlight the potential of silvopastoral systems to improve soil health and resilience, offering a sustainable alternative to traditional livestock management. This study underscores the importance of integrating trees into pastures to restore degraded lands and promote sustainable agricultural practices in tropical regions, contributing to global environmental conservation efforts.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"974 ","pages":"Article 179185"},"PeriodicalIF":8.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143697049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
