Natural coagulants have plenty of advantages over the treatment of dyeing effluents. A laboratory scale experiment was performed to address the treatment of textile dyeing effluent using Madhuca longifolia (Iluppai) oil cake powder (MCP) as a coagulant, sourced from natural indigenous plant-based materials. The coagulant dosage, pH and dye concentration are varied, evaluated and optimized in the lab scale batch coagulation process, and its characterization was performed by \"Fourier transform infrared spectroscopy (FTIR), UV-visible spectrophotometer, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX) analysis and also zeta potential\". Various dosages of MCP were introduced, and the coagulation process was evaluated by examining and comparing the initial and final characteristics of Acid Blue 114 (AB114) dyeing effluent, including pH, chemical oxygen demand (COD), turbidity and colour. In terms of MCP dosage, the maximum efficiency for removing turbidity, COD and colour is 96%, 74.8% and 94.8%, respectively, at the coagulant dose of 2.7 g. The removal efficiency of turbidity, COD and colour is increased when the pH level is 4. The coagulant dose of 2.7 g of MCP has given the maximum turbidity, COD and colour removal efficiency of 97.6%, 75.6% and 95.8%, respectively, at an acidic state of pH 4. The study also investigates the equilibrium adsorption capacity (q_e) of the MCP coagulant material. The obtained values are analyzed and fitted to isotherms, including Langmuir and Freundlich, as well as kinetic models like pseudo-first order and pseudo-second order. The indigenous plant-based material (MCP) is a locally available, cost-effective novel by-product material. It proves to be a viable alternative for treating industrial effluent, demonstrating superior efficiency compared to chemical-based coagulants.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Marine biofouling continues to pose a significant environmental and economic burden, with existing solutions often being environmentally toxic or prohibitively expensive. Natural products, such as enzymes, have emerged as promising alternatives. Shrimp processing wastes are usually dumped to the environment, although they constitute an important source of marine enzymes. In this context, the present study investigates the potential of enzymatic extract derived from shrimp processing waste as an antifouling agent. We focused on the performance and stability of proteolytic enzymes within the extract under various conditions: exposure to seawater (static and dynamic) over time, and resistance to organic solvents. Additionally, we explored field trials using antifouling paints formulated with shrimp extract and we investigated a versatile and simple technology for extract immobilization. The results demonstrate that proteolytic activity in the shrimp extract remained stable over time in seawater and when exposed to organic solvents. Paints containing this extract completely inhibited macrofouling attachment for 7 months. Interestingly, control panels with deactivated enzymes exhibited macroalgae colonization but also showed reduced macroinvertebrate attachment. This suggests that additional compounds within the extract may have antifouling properties. We successfully produced nanocapsules of alginate-chitosan containing the shrimp extract using electrohydrodynamic atomization. While these nanocapsules show promise, further optimization is required. Overall, this study presents encouraging findings for the use of shrimp waste extract in antifouling paint formulations. This approach offers a potentially low-cost and environmentally friendly solution to the biofouling problem.\u0000</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"32 15","pages":"9710 - 9721"},"PeriodicalIF":5.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This study investigates the adsorption mechanism of methylene blue on thiol-norbornene crosslinked polyvinyl alcohol (PVA) hydrogel surfaces using MD simulations for the first time. This adsorption behavior is characterized by analyzing hydrogen bonding, radial distribution function (RDF), mean square displacements, and dye removal efficiency. The hydrogen bonding analysis shows consistent stability of the hydrogel network across different pH conditions. The RDF analysis indicates dissociation of the methylene blue molecule, with the cationic part adsorbing onto PVA's hydroxyl groups and the chloride ion exhibits preferential association with the ions in the pH medium. The mean square displacement result suggests a lower diffusion of methylene blue in pH 12.0 which can enhance the rate of adsorption.

However, the ecotoxicity and environmental safety of nanoparticles need to be evaluated before their large-scale use. This study synthesizes and characterizes magnesium (Mg) and zinc (Zn) co-doped aluminum (Al) oxide (MgZnAl₂O₄) NPs and elucidates its potential growth-promoting or genotoxic performance on barley (<i>Hordeum vulgare</i> L.). XRD, EDX, TEM, SEM, and XPS were used to characterize the MgZnAl₂O₄ NPs. After characterization, the seedlings were grown in a hydroponic solution containing 0, 50, 100, 200, and 400 mg L⁻¹ NPs for 3 weeks. The germination, growth indices, photosynthetic parameters, and nutrient absorption properties were determined. Confocal microscopy, TEM, and SEM were utilized to follow the path and reveal the structural and morphological effects of NPs. The potential genotoxic effect was evaluated using the RAPD-PCR method. Elemental composition analysis of plant parts confirmed that synthesized MgZnAl₂O₄ NPs, sized at 21.8 nm, were up-taken by the plant roots, leading to increased Mg, Zn, and Al contents of leaves. In addition, compared with the untreated control, the abundance of Ca, K, B, Fe, Mn, and Cu were increased by the NPs treatment. In addition, physiological indices like germination rate (~ 11%), root and leaf growth (15–29%), chlorophyll, and carotenoids (~ 39%) pigments were significantly raised by the NPs inclusion. It can be concluded that low concentrations (&lt; 200 mg L⁻¹) of MgZnAl₂O₄ NPs enhance growth parameters effectively and are safe for plant growth. On the other hand, a phytotoxic and genotoxic impact was observed at high concentrations (100–400 mg L⁻¹). However, considerable amounts of NPs were found to be adsorbed on roots, disrupting root morphology and cell membrane integrity, thus nutrient trafficking and transport. Therefore, it is recommended that MgZnAl₂O₄ NPs can be used in barley breeding programs at low concentrations. Adding micro- or macroelements required by plants to the NP composition is a promising way to compensate for plant nutrition. However, the negative effects of MgZnAl₂O₄ NPs on the environment and other living beings due to their genotoxic effects at high doses must be carefully considered.</p></div>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":"32 15","pages":"9593 - 9613"},"PeriodicalIF":5.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
