The seedling growth performance of plants stressed by salinity can be improved by seed priming with plant growth hormones. In the present study, the effects of increasing salinity levels (100 and 150 mM NaCl) alone or in combination with gibberellic acid (GA3) and indole 3-butyric acid (IBA) were investigated in two commonly grown horse gram [Macrotyloma uniflorum (Lam.) Verdc] cultivars (Dapoli 1 and Rajapur) at the seedling stage under laboratory conditions. Results revealed that NaCl-induced salinity stress significantly decreased the root length, shoot length, and total length in both Dapoli 1 and Rajapur cultivars. Seed priming with GA3 (100 ppm) and IBA (50 ppm) significantly enhanced root length, shoot length, and total length of salinity-stressed seedlings. Improved seedling growth performance was associated with increased proline content after seed priming with GA3 and IBA in both cultivars. NaCl-induced salinity stress increased oxidative stress by enhancing the levels of H2O2. Seed priming with GA3 and IBA significantly decreased the H2O2 content in both cultivars. Catalase and Peroxidase enzyme activities were significantly increased and decreased in the salinity-stressed Rajapur cultivar, respectively. Seed priming with GA3 and IBA significantly developed high antioxidative capacity as indicated by improved activities of these enzymes in the Rajapur cultivar compared to Dapoli 1. Overall results suggested that seed priming with GA3 and IBA alone or in combination is an effective, environmentally sustainable way to mitigate salinity stress in different horse gram cultivars.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"93"},"PeriodicalIF":2.7,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144265008","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}

Results revealed that mercury was highest in fish muscle, particularly predatory species, whereas chromium and cadmium were predominantly found in liver tissues. Chromium accumulation was influenced by gender, with females showing higher levels. Older fish exhibit greater cadmium accumulation in liver tissue. Parasite burden was associated with elevated mercury levels in fish muscle. Notably, the cestode Caryophyllaeus laticeps had significantly higher chromium levels than its host, freshwater bream (Abramis brama).

However, the stability and aggregation behavior of DOM-Fe colloids under varying concentrations and mineral compositions remain unclear. Therefore, the binding behavior of these composite colloids with As(III) requires further investigation. This study analyzes the surface charge and particle size variations of the composite colloids to understand their stability and the binding process with As. Results indicate that the C/Fe molar ratio affects the dispersion of the three types of humic acid-iron (HA-Fe) composite colloids. As the C/Fe ratio increases, the Zeta potential of the composite colloids increases, and their particle size decreases, with a minimum size of 135, 232, and 188 nm. When the C/Fe molar ratio is below 4.7, sedimentation occurs, with the maximum sedimentation value (C/C0) reaching 0.7. As pH increases, the Zeta potential of all three HA-Fe composite colloids increases by 6.3, 8.1, and 6.2 mV respectively, and their particle sizes decrease, with average reductions of 336, 483, and 256 nm. The binding capacity with As(III) increases as the C/Fe ratio rises from 0 to 23.3. At a C/Fe ratio of 23.3, the binding coefficients (logKD) with As(III) are 2.42, 2.86, and 2.96 for the three composite colloids, respectively. Among them, the HA-FeO(OH) composite colloid shows the highest binding rate with arsenic at 92% when the C/Fe ratio is 23.3. The binding mechanisms include complexation, redox reactions, and cation bridge formation. The findings provide new insights into the environmental behavior of DOM-Fe at water-soil interfaces and their impact on pollutant migration.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"90"},"PeriodicalIF":2.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245608","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}

Naphthalene has potential uses both for domestic and industrial purposes and is known to be discharged into aquatic ecosystems. Considering the overuse and the probability of elevated discharge of naphthalene in aquatic bodies, this experiment was planned to decipher the consequences of naphthalene on Anabas testudineus, a freshwater fish in terms of histological changes in liver under laboratory conditions. Variable concentrations of naphthalene based on 72 h LC50 value (4.4-5 mgL-1) were administered in water for 72 h. Naphthalene exposure caused histological anomalies like structural modifications in central vein, vacuolation, hypertrophication, necrotic hepatocytes, accumulated blood cells and lipid deposition. Significant modifications like necrosis, hypertrophication and vacuolation were noticed in the hepatic tissues of fish exposed to highest concentration of naphthalene. Hence, the current study exhibited that naphthalene pollution in aquatic ecosystem can affect the health conditions of aquatic fauna.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 6","pages":"91"},"PeriodicalIF":2.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245609","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}

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}

Fibers and fragments were the dominant shapes, primarily composed of polyethylene (PE) and polypropylene (PP). FTIR confirmed polymer-specific functional groups, while SEM-EDS revealed smooth surfaces with minimal heavy metal adsorption, indicating recent contamination.
