We evaluated the biomonitoring potential of unwashed above-ground tissues of Artemisia vulgaris and Calamagrostis purpurea in the Avacha agglomeration, Kamchatka, Russia. A total of 88 A. vulgaris and 62 C. purpurea composite samples collected from urban and natural sites in 2017-2023 were analyzed for Zn, Cu, Pb, and Cd by microwave plasma atomic emission spectrometry. Robust statistical approaches were compared to establish species-specific local screening baselines. The median ± 2 median absolute deviation method was selected for A. vulgaris, whereas the iterative 2σ method was selected for C. purpurea. A. vulgaris showed greater concentration variability and a broader range of pollution load index values in urban sites, consistent with greater responsiveness to local environmental heterogeneity. Principal component analysis indicated contrasting associations among Pb, Zn, Cd, and Cu that are consistent with different source-related contributions to the elemental burden. In contrast, C. purpurea showed limited separation between urban and natural sites and its pollution load index values did not provide a consistent urban-natural contrast. The findings support species-specific, locally derived screening baselines for vegetation monitoring in volcanic settings and identify A. vulgaris as the more informative of the two species for detecting localized deviations from regional background conditions.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149102442","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}

Subsequently, the growth of Money Plant (Epipremnum aureum) was monitored under hydroponic conditions for 21 days as a bioindicator. Thereafter, photosynthetic responses were assessed using a FluorPen photosynthetic analyser. Findings of the study showed a marked spatial variation in metal concentrations, with the highest manganese levels in the Gadheri River (38.66 ppb) and elevated chromium and cadmium levels in Pachmarhi Lake. Chlorophyll fluorescence parameters showed treatment and time dependent variations; however, effective quantum yield remained relatively stable across treatments. Changes in Ft, Fv/Fm, ΨI, and NPQ indicated physiological adjustment and photoprotective energy regulation rather than severe photosynthetic impairment. Overall, the findings suggest that photosynthetic responses were influenced by the integrated chemical characteristics of the water rather than by the total concentration of an individual metal in natural water.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149056708","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}

It is excreted in faeces and may persist in the environment, potentially causing adverse toxic effects on non-target organisms. The purpose of this study is to investigate the degradation of ivermectin in barn ground after subcutaneous administration in beef cattle. To conduct this study, faecal samples were collected from various areas of the cattle barn ground where the animals had received a subcutaneous ivermectin at a dosage of 0.2 mg/kg. The samples were taken over a period of two months. The study demonstrated that the highest ivermectin concentration in faecal samples was detected on day 5, at 153.62 ± 9.76 ng/g. In contrast, the final faecal samples collected on day 60 revealed an ivermectin concentration of 1.92 ± 0.93 ng/g. The calculated half-life of ivermectin in the barn ground was 9.21 days. Following a single dose, ivermectin remains detectable for extended periods, even at low concentrations. This persistence poses a potential risk of significant ecotoxicological harm to non-target organisms and animals in terrestrial and aquatic environments. To minimise this environmental impact, it is crucial to adopt effective manure management strategies and raise awareness among livestock producers and veterinarians regarding the responsible use of ivermectin. Promoting sustainable veterinary practices is essential for protecting the environment.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029462","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}

Consequently, it is important to evaluate the harmful effect of microplastics on ecosystems. Various types of earthworm species act as specific bioindicators of environmental disturbances. Primary goal of this experimental study was to investigate the persistent effects of small sized new and novel thermoplastic i.e. polypropylene on Lampito mauritii. This particular research examined the mortality rates, mass of body, fecundity ability as well as the tolerance ability of earthworm caused by polypropylene. The oxidative stress response of L. mauritii enzymes was assessed by the measuring the activities of guaiacol peroxidase, catalase, superoxide dismutase and glutathione-S-transferase. Throughout the 28-day treatment period, polypropylene caused no mortality in all treatment groups, but it affected the body mass of earthworms at higher concentration (8000 and 16000 mgkg- 1). As compared to control the highest decrease in body mass of L. mauritii was observed in 1600 mgkg- 1 (23%) followed by 8000 mgkg- 1 (11.21%) loss of body weight%. Likewise, the fecundity of L. mauritii decreased with increasing concentrations of polypropylene. Beyond the toxicity study, polypropylene induce oxidative stress and shows slightly declined in GST, SOD and CAT with increase in exposure concentration whereas the POD activity increases with increased in polypropylene dose.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029533","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 investigated the protective potential of a carotenoid-rich fungal pigment from Fusarium tricinctum against cadmium, zinc, chromium, mercury, and copper toxicity in Daphnia magna. HPLC and UV-Vis analyses identified β-carotene as the predominant carotenoid, while the pigment exhibited strong DPPH radical-scavenging activity. Acute toxicity assays determined 48-h LC₅₀ values, and a concentration of 10 µg/L was selected for subsequent co-exposure experiments. ICP-MS analysis revealed that the fungal pigment significantly reduced tissue accumulation of all tested heavy metals compared with metal-only treatments. Moreover, pigment co-exposure attenuated oxidative stress by reducing malondialdehyde levels and modulating antioxidant responses, including SOD, CAT, and GSH. Overall, the F. tricinctum carotenoid pigment enhanced D. magna survival and alleviated heavy metal-induced oxidative damage, demonstrating its potential as a natural protective agent against metal stress in aquatic ecosystems.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981757","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 Populus deltoides W. Bartram ex Marshall (P. deltoides) in a post-mining watershed in Tongling, Anhui Province, China, with a focus on the accumulation characteristics of Cd, Zn, Cu, Pb, and As. The results showed that the soils were heavily contaminated by HMs, particularly Cd, Pb, and As, while Cd exhibited pronounced spatial heterogeneity among sampling sites. HM concentrations in P. deltoides tissues decreased in the order of leaves > bark > roots > stems > branches, and Zn showed the highest overall concentration among the investigated metals. Bioconcentration factor (BCF) analysis indicated a strong enrichment capacity for Cd in leaves (BCF up to 10.01), limited uptake of Zn and Cu, and negligible accumulation of Pb and As. Over a 5-year rotation period, the mean HM accumulation per tree was highest for Zn (10.21 g tree⁻1), followed by Cd (0.30 g tree⁻1). According to the remediation cycle (RC) model, reducing soil Cd contamination by one pollution grade in lightly to moderately contaminated areas required up to 7.45 RCs, whereas achieving background levels required 10.41 RCs. Remediation of Zn-contaminated soils required even longer periods. Overall, these findings suggest that P. deltoides is a promising species for the long-term management of Cd- and Zn-contaminated soils through combined phytoextraction and phytostabilization, providing practical support for ecological restoration and environmental management in mining-affected watersheds.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148975147","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}

Metal concentrations exhibited a significant downstream increase, with peak levels at Qamarwari due to urban and sewage inputs. Seasonal variation showed higher concentrations during autumn and winter, attributed to reduced dilution. Sediments acted as major sinks, while Cyprinus carpio showed higher bioaccumulation, particularly in liver tissues. Although metal levels in edible muscle tissue remained within permissible limits, transfer factor and health risk indices indicate potential long-term risks.
