The treatments were control, with no fertilizer or municipal solid waste compost, multiple combinations of N, P, and K chemical fertilizers, and municipal solid waste compost which were used either once or twice a year. Mature corn plants (Single Cross 704) from the lowest collar were sampled during the end of summer 2019. Corn samples were examined for cadmium, lead, nickel, and zinc concentration. Using the Oracle Crystalball software, health risks were estimated for sheep, dairy cows, beef, broiler, and laying poultry. The highest exposure to cadmium, nickel, and zinc was observed in sheep feeding corn cultivated in T5 treatment, but the highest exposure to lead was observed in sheep fed with corn cultivated in T2 treatment. Cd, Pb, Ni, and Zn exposure and related risk indices were lower than the reported reference values. It can be concluded that the quality of fodder corn grown in the treatments in this study was within the safe range in terms of heavy metal content and did not threaten the health of the investigated animals.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761663","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}

Understanding deposition driven by entrainment is vital for improving hazard mitigation and sediment management strategies. This study employs a small-scale flume setup to examine the interplay between water content (w/c), sediment composition, and bed morphology on granular flow behavior. Sixteen experiments were conducted, varying w/c (20–50%) and erodible bed configurations, with deposit morphology analyzed for width, thickness, and runout length. The findings revealed distinct patterns in deposit morphology across w/c levels. At lower w/c (20–24%), deposits exhibited broad, shorter lobes with minimal scouring, forming cone-shaped structures. Moderate w/c (~ 28%) enhanced flow mobility, producing thicker deposits near the flume bed due to reduced entrainment. At higher w/c (30–50%), deposits shifted further downstream, driven by greater entrainment volumes and longer runout distances. While higher w/c levels decreased deposit thickness, they significantly widened the runout deposits, demonstrating the dual influence of w/c and entrainment. A clear relationship emerged between entrainment and flow mobility, as increased entrainment volumes widened and flattened deposits. Additionally, water content dominated entrainment in controlling deposit thickness, underscoring its critical role in sediment transport dynamics. The deposits were poorly sorted, with a distinct bedding structure akin to natural debris flows, validating the experimental setup. This study provides an efficient and scalable methodology for analyzing granular flow behavior in erodible beds. The results offer insights into sediment transport processes, bridging the gap between mesoscale experiments and real-world applications in natural hazard mitigation and geotechnical engineering.</p></div>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"84 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents research using similar material models, field pressure and deformation monitoring, and surrounding rock pressure theory. Key findings indicate that removing the upper bench lining and excavating the surrounding rock on the expansion side reduces surrounding rock stress, with a more significant pressure decrease on the expansion side. The shallow surrounding rock experiences greater stress reduction than deeper strata. Field monitoring shows similar three-stage patterns (rapid change, slow change, and stability) in anchor shaft force, steel arch stress, and contact stress between the initial support and surrounding rock, stabilizing after 15 h. Stress concentrations occurred at the left and right arch shoulders, with higher stress at the left. The removal of upper bench lining and surrounding rock expansion had a significant impact on stress changes, while lower bench excavation had minimal effect on arch shoulder stress. Physical and field data showed severe damage and stress reduction at the right arch shoulder on the expansion side, causing asymmetric stress and damage distribution. The rates of perimeter rock pressure change during tunnel expansion were significantly higher than during sub-conductor excavation, indicating the substantial influence of construction steps and expansion width.</p></div>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"84 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
