Monitoring changes of TPH content during bioremediation is essential and it is difficult and expensive by traditional approaches. Therefore, finding a cost-effective and easy technique to monitor the TPH content during the bioremediation is very crucial. Magnetic susceptibility as the fast and effective way in this regard was assessed. This study investigated the effectiveness of magnetic susceptibility (χ_lf) as an economical, quick, and efficient tool for monitoring total petroleum hydrocarbon (TPH) content during its biodegradation by non-native bacteria, <i>Pseudomonas aeruginosa and Marinobacter hydrocarbonoclasticus,</i> in an incubation experiment. Two different textual soils were contaminated with four levels of crude oil, inoculated with <i>Pseudomonas aeruginosa</i> and <i>Marinobacter hydrocarbonoclasticus,</i> and then incubated at 22ºC and 80% of field capacity moisture content for 30 and 90 days. TPH and χlf were measured in the initial and treated samples_. The results showed that soil texture did not significantly (<i>P</i> &lt; 0.05) affect the biodegradation rate. TPH content decreased significantly (<i>P</i> &lt; 0.01) after 30 days of incubation (&gt; 60%), especially when inoculated with both bacterial strains. However, no significant differences were observed between the two bacterial strains in two incubation periods. Conversely, χ_lf, iron forms, and magnetite/maghemite content increased significantly (<i>P</i> &lt; 0.05) following incubation, specifically in the presence of both bacteria. These changes were likely attributed to biochemical processes during hydrocarbon biodegradation. The non-linear regression equation demonstrated that χ_lf explained 86% of the variability in TPH in the studied soils. Thus, χ_lf may serve as a reliable and rapid technique for monitoring TPH changes during soil remediation practices for end-users and governing bodies.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904770","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}

Herein, S-nZVI@ATP, a composite material consisting of sulfidized nZVI loaded onto ATP, was utilized to remove Cr(VI), and the corresponding reaction mechanisms was explored. The findings revealed that the removal efficiency of Cr(VI) (<i>R</i>_<i>Cr</i>) for S-nZVI@ATP was 97.93% at S/Fe molar ratio (<i>S/Fe</i>_<i>MRR</i>) of 0.12, S-nZVI/ATP mass ratio (<i>S-nZVI/ATP</i>_<i>MSR</i>) of 4:1, pH of 3, and an initial Cr(VI) concentration of 20 mg/L. In the pH range of 3 to 7, S-nZVI@ATP exhibited excellent removal performance for Cr (VI), with the highest <i>R</i>_<i>Cr</i> 99.71% at pH 3. Coexisting ions such as SO₄²⁻, CO₃²⁻, PO₄³⁻, and HCO₃⁻ showed varying degrees of inhibition on the removal of Cr(VI). HCO₃⁻ displayed positive effects at concentrations of 10 and 15 mmol/L (<i>R</i>_<i>Cr</i> = 99.99%). The removal process followed the Pseudo-second-order kinetic model and Freundlich adsorption isothermal model, with an adsorption amount reaching 19.25 mg/g at equilibrium. Thermodynamic calculations revealed that the material adsorbed Cr(VI) onto the S-nZVI@ATP by spontaneous heat absorption.

Protocatechuic acid (PCA) used as an antioxidant organic acid, can enhance plant tolerance to abiotic stresses in agricultural environments and promote physiological features and plant growth. The experiment, investigated the response of rye (<i>Secale cereale</i> L.) seedlings to freeze–thaw cycles (FTC) and cadmium (Cd) compound stresses and PCA on these seedlings. An integrated biomarker response (IBR) model was used to comprehensively assess the ecological risk posed by Cd and FTC on rye seedlings. Molecular docking studies exposed Cd interacted with SOD and CAT proteins’ active sites. The results demonstrated that FTC and Cd stresses decreased the net photosynthetic rate (Pn), internal CO₂ (Ci), transpiration rate (Tr) and stomatal conductance (Gs) of rye seedlings. While PCA did not perform optimally in completely counteracting these effects, it did improve the seedlings' resistance to the stresses. Notable increases were observed in the activity of peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) enzymes, as well as in soluble protein (SP) levels. Additionally, there was a decrease in malondialdehyde (MDA) content, which is significant because in plants high levels of MDA can cause oxidation. Thus, the study confirmed that PCA has a protective effect on rye plants under compound stresses (FTC and Cd), reducing physiological damage and improve tolerance. It is recommended that, in agricultural practices, the occurrence of these stresses (freeze–thaw and Cd) be minimized to mitigate physiological stress. If the effect of freeze–thaw and Cd continue it can make the serious problem for agriculture. This study establishes a theoretical foundation for mitigating ecological disasters in plants situated in northern high-latitude regions.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904774","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 physicochemical methods currently applied for removing Cl-VOCs are unsustainable due to high cost, inherent complexity, and formation of secondary toxic metabolites. For several decades, biological treatment of wastes has been considered the panacea. In this light, it seems promising to extend the application of bioremediation to treat Cl-VOCs. The current review provides a comprehensive update on the use of bioreactors such as biofilters, biotrickling filters, rotating biological contactors, scrubbers, and membrane bioreactors for the remediation of Cl-VOCs-laden industrial fumes. The integration of physicochemical processes with bioreactors would aid in overcoming the limitations of any individual process and enhance the degradation rate while ensuring the long-term stability of the system. As microbes play a pivotal role in bioreactor systems, various species involved in the remediation of Cl-VOCs are discussed. The diversity of the microbes influences the stability and functioning of the community, which necessitates the incorporation of bacteria and fungi, even algae, rotifers, and nematodes in the bioreactors. The review concludes with suggestions for future research considering the current challenges in realizing the full potential of bioreactors for treating Cl-VOCs.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904772","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}

Groundwater and leachate samples were collected both in pre monsoon (PRM) and post monsoon (POM) period for the estimation of physico-chemical characteristics and heavy metals. The analysis revealed that in research period, most of the parameters concentration except PO₄²⁻, Nickel, lead and zinc were found to decrease after monsoon season in the leachate samples. However, no definite pattern of water quality parameters was observed in the groundwater samples during the two seasons in two years.

This study seeks to evaluate the drinking water quality index (DWQI) and the irrigation water quality index (IWQI) in the coal mining area of Ramgarh, Jharkhand, through the assessment of numerous physicochemical parameters. We derive these characteristics from 10 field samples and 20 physicochemical factors. We utilised these factors in laboratory studies, applying ArcGIS's Inverse Distance Weighted (IDW) methodology for mapping and additional indexing methods. This study employed Pearson correlation to analyse the linear relationship between different physiochemical and water indices. The primary aim of this research is to assess water quality conditions for human consumption and irrigation in mining regions. The study demonstrates that two stations, S1 (47.15) and S9 (47.09), meet the criteria for good drinking water quality. Simultaneously, the fair category includes S4 (64.05), S6 (51.64), and S8 (51.26). In contrast, S7 (89.94) falls under the \"poor quality\" category, while S3 (325.90) and S5 (119.33) are recorded as having very poor quality for drinking purposes under the most unfavourable conditions in this study. The Irrigation Water Quality Index classifies only S5 (176.79) as unsuitable for irrigation, even though the sample exceeds the allowed level. The study found a strong link between the sodium adsorption ratio (SAR) and other measurements, including sodium (.95), chloride (.94), and potassium (.79). The results of this study show that the DWQI and IWQI methods with Geographic Information Systems (GIS) integration can be used together to make better decisions at the local and national levels.
