In this study, the protective effects of 2,6-dimethyl-morpholine dithiocarbamate (DMMDTC) against the toxicity of Co(NO3)2 on Allium cepa L. were investigated. Seven groups of onion bulbs were established to investigate the potential effects of DMMDTC against Co(NO3)2 exposure in root tips. These are a control group, two groups of DMMDTC alone in different concentrations, two groups of Co(NO3)2 in different concentrations, and finally, two groups of combined DMMDTC (1,2) + Co (1,2) in different concentrations were applied to onion roots. The effects of the chemicals on physiological parameters, Mitotic Index (MI), Micro Nucleus (MN), genotoxicity and Co(NO3)2 accumulation in the roots were examined. MI analysis revealed that Co(NO3)2 treatments reduced the MI compared to water control by 52.2-46.6%, depending on the concentration. The combinations of DMMDTC + Co(NO3)2 significantly increased MI while decreasing MN compared to the cobalt-only treatments. However the protective effect of DMMDTC against cobalt toxicity was limited when the data compared to the water control. The heavy damage to epidermis cells and nucleus was also observed in those cobalt applied groups. Co(NO3)2 accumulation in the roots, compared to water control, was also high in Co1-Co2 groups. The DMMDTC used in this study had effects similar to those of plant extracts in reducing genotoxic effects. Therefore, the research highlights the potential benefits of using synthesized DMMDTC on Allium cepa against the toxic effects of cobalt.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"87"},"PeriodicalIF":2.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232882","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}

Effects of three common chelating agents on Cd availability to microorganisms and plants were investigated using solution with similar Cd species profiles. As indicated by a Cd-inducible Escherichia coli biosensor, citric acid, nitrilotriacetic acid, and N,N-bis(carboxymethyl)glutamic acid (GLDA) significantly enhanced microbial Cd availability, with fluorescence intensities adjusted to OD600 increasing by 1.50-1.71, 1.78-1.87, and 1.69-2.10 times. But these agents caused comparable or diminished Cd accumulation in Sedum plumbizincicola, with GLDA causing a 67.7% decrease. Microorganisms with sulfhydryl-rich ligands effectively compete with chelating agents for Cd, unlike less competitive ligands of roots. Thus variations in Cd bioavailability stem from different biological ligands on biological surfaces and secreted by microorganisms and plants, affecting surface interactions and metal speciation. This highlights the role of biological ligands in determining Cd availability.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"86"},"PeriodicalIF":2.7,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207275","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}

However, many are experiencing severe human impacts due to their proximity to urbanization. The main objectives of this study were to determine the concentrations of major and trace elements in lake Edku sediments, and to assess their ecological risk impacts based on Contamination Degree (Cd), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). During March 2022, six sampling stations (S1 through S6) were established across the lake, and a total of 14 elements were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES). Our analyses indicate that sediment collected from sampling stations near to sources of wastewater runoff is the most polluted. For example, S1, which is located near to wastewater discharge, had the highest concentration of Cr, Co, Ni, Cu, Zn, Cd, and Pb (90.9, 23.1, 58.7, 55.2, 81.4, 0.5, and 12.8 µg/g, respectively). Evaluating the sediment PERI revealed that sampling stations S1, S2, and S4 had moderate ecological risk (150 < average PERI < 300), indicating there is a negative environmental impact on the living organisms and water quality of lake Edku. Because lake Edku is important for biodiversity conservation, continuous monitoring of metal contamination should be a top priority, as well as improving the efficiency of wastewater treatment facilities to ensure removal of metals before discharging to coastal ecosystems.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"84"},"PeriodicalIF":2.7,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085624","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 gap in knowledge hinders the development of effective strategies for managing soil pollution and protecting agricultural productivity in areas exposed to wastewater irrigation. Therefore, current pot study was conducted on two castor bean genotypes (NIAB-2020 and DS-30) on Pb contaminated soils of Chakera in glasshouse for a period of 120 days. Results showed that physiological indicators decreased under stressed conditions in NIAB-2020 and DS-30, suggesting impaired plant development. Electrolyte leakage (EL) increased in stressed plants indicating damage to cell membrane due to oxidative damage. Biochemically, the levels of superoxide dismutase (SOD) and peroxidase (POD) decreased whereas catalase (CAT) and ascorbate peroxidase (APX) showed an increase in both castor bean genotypes to mitigate oxidative stress. In similar pattern, both genotypes exhibited a reduction in total soluble proteins (TSP) and total free amino acids (TFA), while conversely total soluble sugars (TSS) and total phenolic contents (TPC) increased under stress conditions. Significant correlation was observed between various physiological, biochemical, and antioxidant enzyme responses, indicating their role as stressed biomarkers on Pb contaminated soils. Overall, NIAB-2020 outperformed DS-30 in terms of physiological and biochemical adaptations, evidencing superior adaptive approach. However, future field trials are compulsory to validate the findings of the study.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 5","pages":"79"},"PeriodicalIF":2.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075013","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}

However, the mechanism of its influence remains unclear, particularly regarding its impact on grassland soil. The study was conducted in the periphery of eutrophic Hulun Lake using a gradient amendment experiment (0%, 3%, 5%, 10% cyanobacterial biomass) on adjacent degraded grassland soils. This design aimed to assess the effects of cyanobacterial inputs on soil physicochemical parameters and microbial community restructuring. Quantitative analyses revealed significant nutrient enrichment, with available phosphorus (AP), available potassium (AK), and nitrogen pools demonstrating differential responses. Nitrogen species exhibited the most pronounced enrichment: total nitrogen (TN) increased by 26.21%, ammonium nitrogen (NH₄⁺-N) by 41.99%, and nitrate nitrogen (NO₃⁻-N) by 54.96% relative to controls. Concurrently, stoichiometric ratios displayed dose-dependent modulation: the total organic carbon to total nitrogen (TOC/TN) ratio decreased by 3.85% under 5% biomass treatment, whereas TOC/AP and TN/AP ratios increased by 13.23% and 18.03%, respectively, indicating altered carbon-phosphorus-nutrient coupling dynamics. Additionally, cyanobacteria enhanced the alpha diversity of the soil bacterial community without altering its overall structure or composition. The decomposition and nutrient release process of cyanobacteria in the soil mainly occurs in the first 30 days, which can improve the soil nutrient content and enhance bacterial community diversity. The application of cyanobacteria for the remediation of degraded grasslands represents a valuable approach that effectively utilizes cyanobacterial resources.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 5","pages":"75"},"PeriodicalIF":2.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144053787","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}
