Red clay, widely dispersed throughout southern China, is commonly employed as roadbed and foundation soils. As a result, it is vital to investigate the changes in shear strength and stress-strain relationships of alkali-contaminated soils. To examine the impact of alkali contamination on red clay's shear strength and stress-strain behavior, we conducted indoor consolidated undrained triaxial shear experiments on red clay samples contaminated with various pH levels (pH 7, pH 9, pH 10, pH 11). The findings indicated that the cementation effect of free oxides in red clay was compromised, and the interparticle connection structure was disrupted due to alkali contamination. As the pH increased, the shear strength of red clay exhibited a persistent decline. Next, an investigation was conducted into the stress-strain normalized characteristics of alkali-contaminated red clay, utilizing the stress-strain relationship curves acquired from the conducted experiments. Ultimately, a prediction equation for the stress-strain relationship of red clay under varying pH pollution was established by matching the stress-strain parameters and utilizing the asymptotic value of the principal stress difference as the normalization factor. The prediction equation accurately forecasts the stress-strain correlation of red clay under varying pH contamination. This study has enhanced comprehension of the shear strength and normalized characteristics of red clay polluted with alkali.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 1","pages":"5"},"PeriodicalIF":2.7,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144493327","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}

The obtained activated sample was subjected to XRD, EDX, and SEM analysis. The surface area was estimated as 913 m2/g using a reported method in literature. The synthesized activated carbon was utilized as sorbent for acid blue 129 and Erioglaucine dyes. The kinetics of the process was evaluated at 20, 40, and 60 °C with best fitting achieved with pseudo-2nd order kinetics model. The correlation coefficient (R2) of the Langmuir model was high approaching to 1 thus exhibited best fitting of the data. The maximal adsorption capacity was 769.23 mg/g for erioglaucine and 833.33 mg/g for acid blue 129 recorded at 333 K. The thermodynamic parameters such as Gibbs free energy, enthalpy and entropy changes were also determined. The ΔG° and ΔH° (- 16.805 kJmol- 1 & - 9.054 kJmol- 1) values were negative indicated the feasibility of the process and its exothermic nature. The increase in disorder at solid-solution interface during the adsorption process was evident from the positive values of ΔS° (79.253 JK- 1 mol- 1 & 39.633 JK- 1) indicated the spontaneity of the process. Further equilibrium was established from 5 to 7 min for both the dyes whereas optimum adsorbent dosage selected was 0.01 g. The synthesized activated carbon has been prepared from a renewable biomass source therefore; it could be the best alternative of synthetic water reclamation methods subjected to further validation by other researchers.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 1","pages":"4"},"PeriodicalIF":2.7,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144493326","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}

Morphological alterations, oxidative stress levels, and the transcription of embryogenesis-related marker genes were assessed. Dimefluthrin exposure induced significant locomotor impairments, characterized by intensified spastic movements and altered swimming trajectories in larvae. Swim bladder formation was inhibited, leading to non-inflated swim bladders. Notably, dimefluthrin exposure resulted in a 43.33% increase in superoxide dismutase (SOD) enzymatic activity and an 82.25% decrease in malondialdehyde (MDA) content compared to controls. Furthermore, dimefluthrin disrupted the expression of dopamine-related genes (th and slc6a3) and swim bladder marker genes (anxa5b and hprt1l). These findings demonstrated that dimefluthrin induces locomotor dysfunction, oxidative stress, and swim bladder non-inflation in zebrafish, providing valuable insights into its potential environmental risk assessment.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 1","pages":"3"},"PeriodicalIF":2.7,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367786","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}

The seedling growth performance of plants stressed by salinity can be improved by seed priming with plant growth hormones. In the present study, the effects of increasing salinity levels (100 and 150 mM NaCl) alone or in combination with gibberellic acid (GA3) and indole 3-butyric acid (IBA) were investigated in two commonly grown horse gram [Macrotyloma uniflorum (Lam.) Verdc] cultivars (Dapoli 1 and Rajapur) at the seedling stage under laboratory conditions. Results revealed that NaCl-induced salinity stress significantly decreased the root length, shoot length, and total length in both Dapoli 1 and Rajapur cultivars. Seed priming with GA3 (100 ppm) and IBA (50 ppm) significantly enhanced root length, shoot length, and total length of salinity-stressed seedlings. Improved seedling growth performance was associated with increased proline content after seed priming with GA3 and IBA in both cultivars. NaCl-induced salinity stress increased oxidative stress by enhancing the levels of H2O2. Seed priming with GA3 and IBA significantly decreased the H2O2 content in both cultivars. Catalase and Peroxidase enzyme activities were significantly increased and decreased in the salinity-stressed Rajapur cultivar, respectively. Seed priming with GA3 and IBA significantly developed high antioxidative capacity as indicated by improved activities of these enzymes in the Rajapur cultivar compared to Dapoli 1. Overall results suggested that seed priming with GA3 and IBA alone or in combination is an effective, environmentally sustainable way to mitigate salinity stress in different horse gram cultivars.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"93"},"PeriodicalIF":2.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144265008","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}

Results revealed that mercury was highest in fish muscle, particularly predatory species, whereas chromium and cadmium were predominantly found in liver tissues. Chromium accumulation was influenced by gender, with females showing higher levels. Older fish exhibit greater cadmium accumulation in liver tissue. Parasite burden was associated with elevated mercury levels in fish muscle.

However, the stability and aggregation behavior of DOM-Fe colloids under varying concentrations and mineral compositions remain unclear. Therefore, the binding behavior of these composite colloids with As(III) requires further investigation. This study analyzes the surface charge and particle size variations of the composite colloids to understand their stability and the binding process with As. Results indicate that the C/Fe molar ratio affects the dispersion of the three types of humic acid-iron (HA-Fe) composite colloids. As the C/Fe ratio increases, the Zeta potential of the composite colloids increases, and their particle size decreases, with a minimum size of 135, 232, and 188 nm. When the C/Fe molar ratio is below 4.7, sedimentation occurs, with the maximum sedimentation value (C/C0) reaching 0.7. As pH increases, the Zeta potential of all three HA-Fe composite colloids increases by 6.3, 8.1, and 6.2 mV respectively, and their particle sizes decrease, with average reductions of 336, 483, and 256 nm. The binding capacity with As(III) increases as the C/Fe ratio rises from 0 to 23.3. At a C/Fe ratio of 23.3, the binding coefficients (logKD) with As(III) are 2.42, 2.86, and 2.96 for the three composite colloids, respectively. Among them, the HA-FeO(OH) composite colloid shows the highest binding rate with arsenic at 92% when the C/Fe ratio is 23.3. The binding mechanisms include complexation, redox reactions, and cation bridge formation. The findings provide new insights into the environmental behavior of DOM-Fe at water-soil interfaces and their impact on pollutant migration.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"90"},"PeriodicalIF":2.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245608","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}

Variable concentrations of naphthalene based on 72 h LC50 value (4.4-5 mgL-1) were administered in water for 72 h. Naphthalene exposure caused histological anomalies like structural modifications in central vein, vacuolation, hypertrophication, necrotic hepatocytes, accumulated blood cells and lipid deposition.
