1. Differentiating Natural Volcanic Baselines and Urban Signals in Artemisia and Calamagrostis of the Avacha Agglomeration (Kamchatka).
1. 区分阿瓦恰城市群（堪察加）蒿属与拂子茅属中的自然火山基线值与城市信号PMID:日期:2026-10-03Establishing environmental reference ranges in volcanically active regions is challenging because lithogenic inputs can overlap with local anthropogenic signals. 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.

2. Eco-toxicological Impact of Polypropylene Microplastics on the Earthworm Lampito mauritii: Effects on Growth and Vital Biomarkers.
2. 聚丙烯微塑料对蚯蚓Lampito mauritii的生态毒理学影响：对生长和关键生物标志物的影响PMID:日期:2026-09-23The contribution of microplastics to the global market continues to grow and diversify. 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). As compared to control the highest decrease in body mass of L. mauritii was observed in 1600 mgkg (23%) followed by 8000 mgkg (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.

3. The Degradation of Ivermectin in the Barn Ground Following Subcutaneous Administration in Beef Cattle.
3. 肉牛皮下注射伊维菌素后牛舍地面的降解情况PMID:日期:2026-09-23Ivermectin is the most used antiparasitic drug in veterinary medicine. 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.

4. Carotenoid-Rich Fungal Pigment from Fusarium tricinctum Mitigates Heavy Metal-Induced Toxicity in Daphnia magna.
4. 富含类胡萝卜素的镰刀菌真菌色素减轻了大型蚤中重金属诱导的毒性PMID:日期:2026-09-16Heavy metals induce toxicity in aquatic organisms through bioaccumulation and oxidative stress. 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.

5. Factors Influencing the Clearance of Polystyrene Microplastics by Oysters: Roles of Environmental Conditions, Food Availability and Selection.
5. 影响牡蛎清除聚苯乙烯微塑料的因素：环境条件、食物可获得性和选择性的作用PMID:日期:2026-09-15This study investigated the abiotic and biotic factors regulating the removal of polystyrene microplastics (PS-MPs) from the water column by the oyster Crassostrea hongkongensis. Our data revealed that MP sequestration is highly dependent on environmental conditions and food characteristics. Optimal clearance occurred at 25 °C and medium estuarine salinity (20 psu), while extreme thermal stress (30 °C) and hyposaline conditions (5 psu) significantly depressed filtration. Light condition had little effect on the removal of PS-MPs. Increased food density remarkably stimulated oyster's clearance of PS-MPs, though high concentrations shifted the removal mechanism toward pre-ingestive rejection via pseudofeces. Furthermore, selective feeding on preferred Isochrysis galbana, Chaetoceros gracilis and Phaeodactylum tricornutum yielded significantly higher removal efficiencies than Thalassiosira weissflogii, Dunaliella salina and Chlorella vulgaris. These findings improve our understanding of how abiotic and biotic factors regulate bivalve's removal and pelagic-benthic transport of microplastics in fluctuating coastal environments.

6. Transcriptional Responses of Electrolysis-Induced Dysfunctional Endocrine in Zebrafish (Danio rerio) Embryos.
6. 电解诱导斑马鱼（Danio rerio）胚胎内分泌功能障碍的转录反应PMID:日期:2026-09-15Electrolysis is a cost-effective and efficient technology for pollutant removal, yet its potential ecological risks remain poorly understood. This study systematically examined the impact of electrolysis zebrafish (Danio rerio) embryonic development and endocrine function through transcriptomic analysis. Findings demonstrated that electrolytic exposure significantly modulated 585 differentially expressed genes (DEGs) involved in thyroid hormone signaling, glucose metabolism, and stress response. qRT-PCR validated the dysregulation of genes associated with ion homeostasis, endoplasmic reticulum stress, and cell-matrix interactions, linking these molecular shifts to endocrine disruption and developmental impairments. Additionally, increased Na⁺, K⁺-ATPase activity and elevated lactate levels indicated a metabolic shift from aerobic to anaerobic energy production. This study constitutes the first comprehensive investigation into the molecular mechanisms of electrolysis-induced endocrine toxicity, providing valuable insights for the biological safety assessment of electrolytic methods employed in water pollution control.

7. DGT Passive Samplers as Monitoring Alternatives When Heavy Metal Toxicity Eliminates Bioindicators in Contaminated Sediments.
PMID:日期:2026-09-15Heavy metal pollution in sediments impacts benthic ecosystems. This study evaluated the adverse effects of Cd, Cu, and As on Tubifex tubifex and compared bioaccumulation with diffusive gradients in thin-films (DGT) passive samplers at three exposure doses. In medium (1.87 mg kg Cd, 228 mg kg Cu, 44.7 mg kg As) and high concentrations, 100% lethality occurred after 12 h, preventing bioaccumulation evaluation. Only low concentrations (0.4 mg kg Cd, 48 mg kg Cu, 15 mg kg As) allowed 10-day monitoring. DGT samplers provided quantitative physicochemically labile metal fraction measurements across all treatments, with reliable linear accumulation observed for Cd (R=0.99, p=0.001) and As (R=0.93, p=0.008) including at lethal concentrations. Cu accumulation at the High treatment showed poor linearity (R=0.01, p=0.847), attributed to potential binding layer saturation under extreme contamination. DGT provides a complementary physicochemical exposure assessment tool when indicator mortality prevents traditional biomonitoring in contaminated sediments.

8. Comparison of Cadmium Efflux in Wheat (Triticum aestivum) Cultivars with Contrasting Cadmium Accumulation.
8. 不同镉积累特性小麦（Triticum aestivum）品种的镉外排比较PMID:日期:2026-09-15Cadmium (Cd) is a highly toxic heavy metal threatening human health. Wheat readily translocates Cd to grains, posing food safety risks in contaminated soils. Screening low-Cd cultivars is therefore critical. In pot experiments with 53 wheat cultivars, Kaimai 21 (KM21) and Lunxuan 6 (LX6) showed the lowest and highest grain Cd, respectively. Under 5-10 µM Cd in hydroponics, KM21 harbored 30.1%-63.6% lower root Cd, 54.7%-69.1% lower shoot Cd, and exhibited superior root growth and Cd tolerance than LX6. Crucially, KM21 showed a 36.9% higher Cd efflux rate and a larger Cd efflux proportion than LX6 (44.3% vs. 15.5%). Real-time Cd flux measurements using Non-invasive Micro-test Technology (NMT) further confirmed higher Cd efflux capacity in KM21, which contributed to higher Cd tolerance and lower Cd accumulation. Overall, KM21 is a stably high-Cd efflux and low-Cd accumulation wheat cultivar suitable for safe production in Cd-contaminated soils.

9. Biochar and Organic Matter as Tools for Mitigating Microplastic Effects in Agricultural Soils.
9. 生物炭和有机质作为缓解农业土壤中微塑料影响的工具PMID:日期:2026-09-15Microplastic (MP) contamination threatens soil health, yet effective remediation strategies remain underexplored. This study aimed to address this gap by evaluating the impact of biochar and organic matter on the properties of MP-contaminated soils. Sandy loam (SL) and clay loam (CL) soils were contaminated with 1% (w/w) low-density polyethylene MPs and amended with organic matter (rice husk, compost, cow manure) or their biochar at 2% and 5% (v/v) rates in a 100-day incubation experiment. Results showed that biochar reduced pH to 7.2 (vs. 7.8 in control) and EC by 55.8% in SL, while increasing it by 28.5% in CL with 5% biochar. Organic carbon rose to 17.18 g kg with organic matter and 14.43 g kg with biochar (vs. 2.53 g kg in control), phosphorus increased by up to 270.5%, and potassium by 89.1%. Bulk density decreased to 1.15 g cm⁻, mean weight diameter improved to 0.77 mm, and microbial respiration reached 0.127 mg CO₂ g day with 5% biochar. Both amendments mitigated MP effects, with biochar excelling at higher rates. These findings suggest that integrating biochar and organic matter into soil management practices offers a promising approach by improving soil chemical, physical, and biological properties.

10. Dynamic Degradation of Four Herbicides in Soil and Phytotoxicity to Chili and Tobacco.
10. 四种除草剂在土壤中的动态降解及其对辣椒和烟草的药害PMID:日期:2026-09-15Herbicide carryover from wheat production can injure sensitive rotational cash crops, but compound-specific replanting guidance under matched soil and climatic conditions is limited. We combined an optimized QuEChERS method with ultra-high performance liquid chromatography to quantify soil residues of mesosulfuron-methyl, pyroxsulam, diflufenican, and pyroxasulfone and evaluate the phytotoxicity of these herbicides to rotational chili and tobacco. The recoveries of the four herbicides at 0.1-1 mg/kg spiking levels ranged from 74.42 to 117.33%, which fell within the acceptable recovery range for residue analysis, with RSDs less than 6.69%. The results of field experiments demonstrated that the half-lives of pyroxsulam, mesosulfuron-methyl, pyroxasulfone, and diflufenican were 9.4, 22.7, 113.6, and 203.8 days, respectively. The bioassays indicated that GR of these herbicides on chili were 0.084, 0.116, 0.041, and 3.986 mg/kg, respectively. Similarly, the GR of these herbicides on tobacco were 0.035, 0.128, 0.014, and 4.146 mg/kg, respectively. The safe intervals for the cultivation of chili and tobacco should exceed 3 months following the application of pyroxsulam and mesosulfuron-methyl. However, owing to the prolonged residual periods of pyroxasulfone and diflufenican in the soil, it is necessary to establish a safe planting interval for chili and tobacco that exceeds 24 months. This study provides a theoretical foundation for determining safe replanting practices for chili and tobacco as rotational crops following wheat field application of the four tested herbicides.
