Microplastics were extracted from soil and sediment samples and characterized by shape, color, and polymer type using visual analysis and ATR-FTIR spectroscopy. The most abundant MP shapes identified were fragments (45.5 % in soil, 57.7 % in aquatic sediments), with polypropylene and polyurethane being the predominant polymer types. Blue and red were the most common colours observed. Potential MP sources include plastic waste, agricultural films, and sewage sludge. The study also examined the concentration of heavy metals (Cd, Cr, Zn) in MPs and compared them to the surrounding soil and sediment. Results indicated that MPs can act as vectors for heavy metals, potentially increasing their toxicity and environmental impact, with higher concentrations of Zn observed in MPs compared to sediments. When compared to terrestrial sediments, the aquatic sediments are found to have a higher concentration of MP contamination. Microplastics and sediment samples both occasionally showed detectable levels of Cd, Cr, and Zn, but Pb and Cu were below the detection limit in all cases. Cd concentrations reached up to 0.146 mg/g and Zn up to 15.31 mg/g in microplastic samples from the study area. These MPs can enter food chains through flora and fauna, affecting soil biophysics and potentially contaminating groundwater. Direct field observations suggest that human daily plastic usage is a significant source of microplastics in aquatic environments, while agricultural practices and waste management contribute to terrestrial microplastic pollution. This research highlights the widespread contamination of MPs and the associated risks of heavy metal pollution, emphasizing the need for effective waste management and mitigation strategies to protect ecosystem health. This research is the first to provide baseline data on trace metal concentrations in aquatic microplastics from the Coimbatore area.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"7 ","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The produced nanocomposite was validated using XRD, XPS, UV-Visible, and SEM/EDAX techniques. The higher photocatalytic activity of BaO-CeO₂/TiO₂ compared to CeO₂/TiO₂ could be attributed to an increase in pore diameter, surface area, and oxygen vacancies, as determined by photoluminescence and BET studies. The energy band gap of the BCT composite, calculated using UV-Visible spectroscopy, decreased from 3.32 eV (for pure TiO₂) to 2.43 eV with BaO-CeO₂ incorporation, indicating enhanced visible light absorption. Additionally, the surface area increased from 81.40 m²/g for TiO₂ to 86.24 m²/g for CT and further to 92.98 m²/g for BCT, as determined by BET analysis. The percentage degradation is highest for IC (95.76 %) and RhB (95.70 %) dyes. After four cycles, IC and RhB dyes degraded by around 94.9 % and 93.9 %, respectively, which is comparable to the % degradation of the first cycle of around 96 %. pH analysis reveals that IC and RhB dyes degrade more effectively in alkaline (pH=9) and neutral (pH=7) conditions than in acidic environments. The BaO-CeO₂/TiO₂ nanocomposite remains stable after four cycles of degradation. Kinetic investigations show that both BaO-CeO₂/TiO₂ and CeO₂/TiO₂ can fit with first-order (f.o) models (R²=1).

By adopting a systematic approach, this study ensures that the nanoparticles achieve the desired properties while minimizing waste in the production process. Chitosan is a biopolymer derived from crustacean waste while carrageenan can be extracted from seaweeds, an abundant marine resource. These raw materials can be used as encapsulating materials to address the limitations of bioactive compounds in drug delivery and other applications. The process involves selecting the appropriate chitosan molecular weight, carrageenan type, chitosan: carrageenan ratio, crosslinker type, and crosslinker concentration. The four-step formulation process identified a 5:1:1:3 ratio of low molecular weight chitosan, κ-carrageenan, sodium tripolyphosphate (STPP), and calcium chloride (CaCl₂) as optimal, yielding nanoparticles with a hydrodynamic diameter of approximately 350 nm as measured by DLS.

The demand for oil and its derivatives has led to increased exploration and exploitation activities in the downstream sector. Accidental discharge of crude oil causes environmental degradation in oil-producing areas. It is very difficult to avoid accidental discharge; hence, efforts are being put in place for remediation of the oil spill as soon as it happens. Advanced technologies for oil spill response are the best remediation strategies but are very expensive. High cost of advanced oil spill treatment necessitates the search for affordable methods for remediating oil-polluted water. This article puts together a comprehensive and up-to-date review on oil spillage and occurrences, remediation techniques of oil spillage, sorbents for oil mop up, biomass and conversion of diverse biomass resources for removal of oil, recycling and reusability of spent adsorbents as well as factors influencing removal of oil. Biomass resources are low-cost, renewable, and readily available agricultural byproduct. Efficient utilization of these huge resources reduces disposal problems and adds value to underutilized materials. Conversion of biomass to adsorbents through various treatments (physical or chemical or combination of physical and chemical methods) is now the focus of some researchers and the results are promising. This review investigates the efficacy of biomass-derived sorbents in oil spill remediation, emphasizing their capacity to reduce environmental impact while supporting circular economy strategies through enhanced waste valorization.
