This review has focused on the chemical interactions of chromium variants in soil and the sequestration of chromium using the soil–plant interface in the rhizosphere. The application of plant hyper-accumulators on chromium-contaminated soil for chromium sequestration is an attempt to minimize chromium toxicity of mining and industrial belts. This review utilized the PRISMA 2009 systematic review methodology. The literature screening was conducted by searching databases such as Scopus, Google Scholar, and Web of Science up to 2025 using specific keywords. In countries like Kazakhstan, South Africa, and India, more than 90% of world shipping-grade mine reserves of chromium are present. The mining and metallurgy of chromium can threaten the environmental quality and the region’s public health. The Sukinda chromite mines in India are globally known for their rich chromite mining, metallurgy, and eco-toxicity. The present article analyzes the ecological challenges and searches for possible interactions of chromium variants in soil. The solution to mitigate chromium toxicity is possible using the rhizospheric soil–plant interface. This article’s findings and discussion section help solve ecological challenges and strive for healthy soil at chromium-polluted sites. This review article can contribute to sustainable soil quality improvement at mining and industrial belts. Further research on the isotopic tracer technique is recommended to enhance the understanding of chromium dynamics in soil.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944260","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 hourly mean PM_2.5 concentrations from December 2017 to July 2021 were 24.3 ± 14.1 µg/m³. PM_2.5 levels were typically higher in winter, on weekends, and during religious events compared to summer, weekdays, and typical days, with some peak concentrations occurring randomly. Daytime PM_2.5 levels generally exceeded nighttime background levels by 30–50%, with certain religious activities causing up to 80% increases. Spatial analysis identified temples and markets as pollution hotspots. Using a generalized additive mixed model, we found that the COVID-19 pandemic shutdown and higher wind speeds negatively impacted PM concentrations. Religious events, traffic, and vendors were significant PM sources, continually influencing community air quality throughout the 3.5-year monitoring period. This study demonstrates the value of long-term PM monitoring in capturing unexpected peaks, identifying critical sources, and revealing intricate temporospatial distributions. Research-grade low-cost sensor networks complement traditional monitoring stations by facilitating source identification in targeted communities and providing representative PM exposure data for long-term environmental epidemiological research.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10661-025-14098-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Concentration and geochemically normalized data were used to distinguish between the natural and anthropogenic origins of elements, determine their background levels, and map out the contaminated areas. The content of elements from natural sources remained essentially constant and revealed small variation, while those of anthropogenic and geogenic origins exhibited relatively high variability. Elevated content and significant variation were observed for Cr, Ni, and Co, with an increasing trend, particularly in the eastern part.

Time-lapse electrical resistivity tomography (TL-ERT) has emerged as a popular monitoring tool for identifying target decontamination areas during remediation planning and analyzing contamination dynamics at polluted sites. In this study, twelve (12) survey lines were executed in a 200 by 100 m² grid at four time scales at a pollution site in Kegbara Dere, Ogoniland, Southern Nigeria. The grid lines were collated into a 3-D dataset using a 3-D collation code. The independent inversion of the 3-D datasets displayed acute variations in the electrical resistivity (ER) of the contaminants in response to precipitation. 3-D depth slices revealed six layers at depths ranging from 2.50 to 21.9 m. Time-based evaluations from the 3-D ERT models show a reduction in the ER of the contaminant plume during the rainy season. This tendency is due to the diluting impact of rainfall, which raises the water content of the soil during the rainy season. The TL 3-D datasets were used to perform 4-D ERT inversion with an in-house code, and the results were examined to show the real-time position of the contaminated plume and the migration flow pathway moving southwest of the spill site. A maximum depth of 48.0 m was investigated. The 4-D inversion was capable of eliminating time-related inversion artifacts in order to identify the preferred flow route of contaminant plumes at the spill site. Investigation of water specimens collected from five boreholes at the spill site displayed the average amount of total petroleum hydrocarbon (TPH) for the specimens as 739.51 µg/L, which surpassed the directorate of petroleum resources (DPR) margins (50 and 600 µg/L). The summed poly aromatic hydrocarbons (ƩPAHs) amount in the specimens is valued up to 0.70 µg/L in BH₁, 0.79 µg/L in BH₂, 0.36 µg/L in BH₃, 1.00 µg/L in BH₄, and 1.89 µg/L in BH₅, which are beyond the DPR target margin of 0.15 µg/L. BTEX concentrations also displayed elevated amounts in the specimens. The direction of groundwater flow is towards BH₄, located southwest of the spill site, indicating the most potential receptor area at risk of contamination. Based on this, future TL-ERT monitoring programs should be integrated with geochemical data systems, providing local validation of variation in ER of pollution sites using 4-D ERT inversion capable of minimizing the effects of rainfall on the TL dataset.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 6","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938486","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}

Green and cost-effective biochar (BC) shows considerable potential for addressing environmental issues, including the concurrent elimination of cadmium (Cd(II)) and arsenic (As(III)) from water and soil after nano-sized goethite modification. However, the behavior of goethite-modified rice straw-derived biochar (GBC) during co-adsorption of Cd (II)) and As (III)) in the presence of competing ions and anoxic vs oxic environments is unclear yet. This experiment (GBC) was successfully synthesized to study co-adsorption and the effects of environmental factors on it. The adsorption kinetics and isotherms for the mixed adsorption of Cd(II) and As(III) onto GBC showed that the pseudo-2nd-order model (<i>R</i>² Cd(II) = 0.998, <i>R</i>² As(III) = 0.996) and the Langmuir model (<i>R</i>² Cd(II) = 0.982, <i>R</i>² As(III) = 0.997) were both correctly portrayed. The highest adsorption of As(III) was 87.38 mg/g, and Cd(II) was 71.07 mg/g in a single adsorption system, which is considerably more significant than the values of 68.6 and 48.38 mg/g, correspondingly, in the co-adsorption system. The competitive adsorption of Cd(II) and As(III) on GBC was primarily driven by co-precipitation and ion exchange. Its efficacy in soil systems under aerobic and anaerobic situations remained undisturbed. At the same time, the anaerobic environment favors Cd adsorption, and the aerobic environment favors more As remediation in an aqueous system. The interactive ions Ca²⁺ and Mg²⁺ significantly enhanced the adsorption of As(III). On the other hand, phosphate and humic acid significantly promote Cd(II) adsorption.
