However, limited attention has been on the phytotoxicity evolution and their cause of degraded wastewater. Here, two representative coordination-structured dyeing wastewaters were first degraded using a BDD anode, and the resulting degradation intermediates were analyzed. Subsequently, lettuce seed root length, shoot length, and germination rate were evaluated to assess wastewater's phytotoxicity at different degradation periods. Finally, acute toxicity and the relative concentration changes of intermediates were further analyzed to identify the causes of toxicity. Results indicated that the treated wastewater was more toxic than pre-oxidation due to the generation of multiple toxic intermediates, significantly inhibiting seed growth. The synergistic effects of toxic substances and Na2SO4 electrolytes contributed to increased toxicity. This study demonstrated that the decolorization process of dyeing wastewater through anodic oxidation was toxic and provided a basis for evaluating the agricultural reuse potential of oxidized wastewater.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 4","pages":"48"},"PeriodicalIF":2.2,"publicationDate":"2025-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145231132","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}

This study quantified the abundance, physical characteristics, and polymer types of MPs in the gastrointestinal tracts of two key fish species, Chinese silver pomfret (Pampus chinensis) and white pomfret (Pampus argenteus), collected from the offshore fishing grounds of Bangladesh during March 2024. A total of 25 adult specimens per species were analyzed via oxidative digestion, density separation, and filtration. The polymers of the isolated MPs were identified using Fourier Transform Infrared Spectroscopy (FTIR). MPs were detected in 100% of specimens, with mean abundances of 20.0 items/fish in P. chinensis and 6.6 items/fish in P. argenteus. Fiber-shaped (59-64%) and transparent (53-65%) MPs, predominantly < 500 µm, were most common. Polyamide (PA) and polyethylene terephthalate (PET) were the main polymers. Ecological risk assessment using the Polymer Hazard Index (PHI) indicated the presence of high-risk polymers, but the Pollution Load Index (PLI) suggested overall minor MP contamination relative to the reference baseline. These findings highlight the widespread occurrence of MPs and the predominance of fishing-related polymers in offshore pomfrets of the Bay of Bengal. Notwithstanding the limitations of our sample size and spatial scope, these initial results provide first evidence on the need for regionally coordinated monitoring, improved plastic waste management, and further research on biological effects and food web transfer in tropical marine systems.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 4","pages":"47"},"PeriodicalIF":2.2,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184486","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}

This study evaluated the phytoremediation potential of three ornamental plant species-Epipremnum aureum, Tagetes erecta, and Portulaca grandiflora-for anthracene-contaminated soil. After 60 days of exposure to anthracene at concentrations of 25, 50, and 100 mg kg-1, various parameters including growth, chlorophyll content, malondialdehyde (MDA) levels, and oxidative stress-related enzyme activity-were evaluated. Results revealed that in the presence of anthracene, E. aureum showed no visible stress symptoms, while P. grandiflora exhibited mild stress. In contrast, anthracene treated T. erecta experienced significant reductions in biomass (18.10-62.07%), moisture content (4.65-8.31%), shoot length (20.19-40.07%) and increased root length (14.18-62.92%) compared to the control. The total chlorophyll content in E. aureum and P. grandiflora increased at concentration of 100 mg kg-1, whereas T. erecta exhibited hormesis in chlorophyll content. Presence of anthracene significantly increased MDA concentrations and altered the oxidative stress related parameters in all three plants. Epipremnum aureum demonstrated the highest anthracene removal efficiency (52.82 ± 2.23%), followed by P. grandiflora (31.64 ± 2.68%) and T. erecta (21.11 ± 2.65%).

Results indicated significant alterations in enzyme levels, including increased levels of aspartate transferase, alanine transferase, and lactate dehydrogenase, suggesting cellular damage. In addition, the levels of energy metabolism regulators such as creatine kinase, alkaline phosphatase and amylase changed due to the oxidative effect of midazolam. Additionally, antioxidant levels, including albumin, uric acid and bilirubin were altered, indicating a response to oxidative stress. Molecular docking studies revealed a strong interaction between midazolam with juvenile hormone and 20-hydroxyecdysone hormone binding proteins, suggesting potential disruption of the endocrine system.

Additionally, the regulatory effects of different nano-Se concentrations on barley seedlings under Cd stress were investigated. The results revealed that a high concentration of nano-Se inhibited barley growth, whereas low doses promoted plant growth under Cd stress, with the highest growth parameters recorded at 2 µmol L- 1 (µM) nano-Se. Furthermore, low doses of nano-Se increased chlorophyll levels and improved photosynthetic efficiency. Additionally, nano-Se application at low concentrations protected barley plants from oxidative damage by reducing the levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2), as well as decreasing the activities of root peroxidase (POD) and superoxide dismutase (SOD) induced by Cd stress, as well as reducing the total flavonoid content.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 4","pages":"45"},"PeriodicalIF":2.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145172127","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}

We implemented a four-season field study to evaluate how different SR intensities (NSR: no rice straw was removed; HSR: half of the rice straw was removed; TSR: all the rice straw was removed) influence Cd availability in this system. Our findings indicated that after three and four consecutive seasons of SR, the DTPA-extractable Cd levels showed notable reductions of 12.2% and 13.7%, respectively. SR also decreased grain Cd concentration (CdG) in subsequent seasons, demonstrating a dose-dependent response. The CdG after one, two, three, and four seasons of TSR treatment fell by 9.0%, 25.2%, 16.8%, and 41.7%, respectively, compared to that following NSR treatment. Notably, late-season SR proved more effective in CdG reduction than early-season SR. Statistical analysis confirmed a strong positive association between CdG and DTPA-extractable Cd. The primary mechanism underlying CdG reduction appears to be the decreased Cd bioavailability in soil resulting from SR practices. These findings establish multi-season total straw removal as a sustainable phyto-management strategy for Cd-polluted rice cultivation systems.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"115 3","pages":"40"},"PeriodicalIF":2.2,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022598","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}
