Large amounts of microplastics enter surface waters through wastewater and stormwater. Therefore, it is necessary to develop simple and accessible methodologies as a foundation for establishing reliable and effective strategies for microplastic removal from aquatic environmental samples. In this study, the removal of microplastics (< 1 mm) at laboratory scale using synthetic microplastics is investigated by three methods: filtration, centrifugation and flocculation. For this purpose, polypropylene-based microplastic particles are prepared and turbidity is used to measure removal. In this study, all three methods are investigated to determine a more effective method for the removal of microplastic particles. Among the three methods studied, the centrifuge method showed higher removal efficiency than the filtration and flocculation methods for the removal of microplastic particles from aqueous solution. The removal efficiency of microplastic particles by the centrifugation method reached 95.6% and was 90.6% by the filtration method. The flocculation method has a lower removal efficiency of microplastic particles than the centrifugation and filtration methods, ranging from 75.6 to 81.8%. In general, the results show that centrifugation is the more suitable and efficient method to remove microplastic particles from aqueous solution.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 1","pages":"12"},"PeriodicalIF":2.7,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625113","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}

However, there are few studies on the immobilization of Pb in alkaline agriculture soil amend with nHAP. This study applied 0.5% and 1% nHAP as remediation materials to two Pb contaminated alkaline soils (A and B) from the surrounding of substation in northern China. Comprehensive evaluations of Pb mobility were conducted using the Tessier sequence extraction method, DTPA extraction, and in vitro gastrointestinal simulation (SBRC and PBET methods). The Tessier sequence extraction results revealed that following nHAP addition, there was a shift of Pb towards the residual fraction, with decreases in exchangeable, carbonate, and Fe/Mn oxide fraction. The risk assessment code (RAC) decreased from 27.7 to 36.0% to 21.9-35.1%, and the mobility factor (MF) dropped from 78.8 to 85.9% to 65.6-75.0%. DTPA extraction indicated contrasting effects: the bioavailable Pb extracted by DTPA assay in soil A increased from 36.6% to 43.0-58.3%, while the bioavailable Pb in soil B decreased from 68.3% to 48.4-52.7%. Similar to DTPA results, the Pb bioaccessibility of soil A increased from 63.9% to 41.9% to 70.0-72.6% and 47.6-63.8% in SBRC and PBET gastric phase after 0.5% and 1.0% nHAP treatments 90 days. However, the Pb bioaccessibility of soil B decreased from 76.6% to 56.5% to 54.9-56.5%, 35.0-35.6% by SBRC and PBET, respectively.

Sequential extraction in the DC samples showed that the concentration of REE in the fractions followed the order of residual > reducible > weak acid soluble > oxidant. The environmental risk, evaluated by the risk assessment code (RAC), potential ecological risk factor ([Formula: see text]) and potential ecological risk index (IR), indicated, in general, a low ecological risk associated with the REE in DC samples.

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.

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}
