However, research on the bioaccumulation of microplastics in brackish water fish and their effects remains limited. The present study investigated the bioaccumulation and effects of polystyrene microplastics (PS-MPs) in juvenile brackish water fish, pearl spot (Etroplus suratensis). Fish were exposed to 0, 0.2, 2, and 4 mg/L of 1 µm-sized PS-MPs for 14 days. PS-MPs were found in the gastrointestinal tract, gills, liver, spleen, muscle, and brain, with the highest concentration in the intestine and the lowest in the brain. Exposure to PS-MPs led to elevated serum level of glucose, total protein, total cholesterol, serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase (SGPT), and alkaline phosphatase (ALP). Antioxidant parameters such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and total antioxidant capacity (TAC) decreased, while malondialdehyde (MDA) level and protein carbonyl (PC) content increased. PS-MP exposure down-regulated hepatic expression of NRF2 and P53, increased cortisol levels, and up-regulated HSP70 gene expression in a dose-dependent manner. Additionally, PS-MPs down-regulated expression of IGF1 and CYP1A in the liver. This is the first comprehensive research that has revealed the extent to which PS-MPs accumulate in various tissues of brackish water fish species after being exposed to environmentally significant concentrations. It also demonstrates the associated toxicity in an array of antioxidant indicators.</p>","PeriodicalId":11497,"journal":{"name":"Ecotoxicology","volume":" ","pages":"1228-1243"},"PeriodicalIF":2.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144324764","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 aimed to assess the resistance of native species to invasive species in plant communities with varying species densities, focusing on growth traits and soil properties under the influence of different soil pollutants. Four native experimental communities varying in number of species were established, with each community paired with a distinct invasive species., i.e., C1 (four natives, i.e., Lactuca indica L., Plantago asiatica L., Leonurus japonicus Houtt., Alternanthera sessilis L. + Symphyotrichum subulatum (Michx.) G. L.), C2 (four natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis + Sphagneticola trilobata L.), C3 (five natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis, Hemistepta lyrata (Bunge) + S. subulatum), C4 (five natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis, H. lyrata + S. trilobata). These communities were exposed to four soil pollutant treatments: (i) no pollutants (CK), (ii) PE microplastic particles (MP), (iii) cadmium, representing a heavy metal (HM), and (iv) both MP + HM. An ANOVA showed that MP, HM, and MP + HM significantly affected the biomass of both native and invasive species across all four communities (P < 0.05). Furthermore, microbial biomass carbon, nitrogen, and CO₂ emissions were higher in C2 and C4 soils (invaded by S. trilobata) than in C1 and C3 soils (invaded by S. subulatum). The invasion resistance index (IRIN) of the native species increased in C1 compared to C2 by 74.50, 49.86, 18.34, and 24.72% under CK, MP, HM, and MP + HM treatments, respectively. Similarly, the IRIN in C3 increased relative to C4 by 48.30, 30.45, 22.56, and 31.03% under the same treatments.

The consequences of acute intoxication are well-documented, however sub-lethal exposure is a less well-researched topic. The present study provides an experimental evaluation of the lethal and sub-lethal effects of clomazone, a widely used herbicide, on the apple snail Pomacea sp. In the initial series of trials, the organisms were exposed to four nominal concentrations of clomazone (0, 4.86, 9.25 and 15.93 mg L⁻¹) for of 96 h to evaluate mortality and determine the lethal concentration (LC₅₀). In addition, sub-lethal responses such as behavioral activity, oxygen consumption (OC), ingestion rate (IR), ammonia excretion rate (AER) and growth were evaluated after being exposed for 76 days to concentrations of 15 and 150 µg L⁻¹. The LC₅₀ for clomazone was 14.59 mg L⁻¹ (95% CI: 13.67-15.51). A significant (p < 0.05) dose-dependent reduction in both behavioral activity (quantified as area under the curve, AUC) and OC was observed in the short term. In contrast, during chronic exposure at 150 µg L⁻¹, no significant changes in OC, AER, IR, or growth were registered along the whole period. These findings, based on a multi-endpoint approach, suggest that physiological and behavioral responses of Pomacea sp. are sensitive to clomazone exposure. This highlights the species' potential as a bioindicator, but more studies are needed to explore their responses at multiple levels and life stages to develop environmental management tools in the context of risk assessment.</p>","PeriodicalId":11497,"journal":{"name":"Ecotoxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144946969","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 effects of such exposure on juvenile Podocnemis expansa over a 21-day period, addressing a critical gap in understanding these impacts on chelonians. The effluent, collected from a \"wet-blue\" tannery and rich in heavy metals (Cr, Zn, Mg, Ca), was tested at three environmentally relevant dilutions: TE1.4 (1.4%), TE3.1 (3.1%), and TE6.5 (6.5%), along with negative (C) and positive (C+) control groups. Behavioral, physiological, and cyto-genotoxic biomarkers were evaluated. Although body mass was not significantly affected, reduced locomotor activity and increased latency to the first upward movement were observed, particularly in the TE3.1 and TE6.5 groups. In the righting response test, the TE6.5 group showed higher attempts and reduced righting efficiency, indicating neuromuscular impairments. Additionally, glycemic levels decreased by up to 11.3% in the TE3.1 and TE6.5 groups, while bioaccumulation of Cr, Zn, and Ca in the liver was significantly higher in the TE6.5 group. Social behavior alterations were also evident, with exposed individuals displaying selective responses and, in the TE6.5 group, behavioral inversion characterized by attraction to heterospecific stimuli. The significant increase in erythrocyte nuclear abnormalities indicated cytogenotoxic effects comparable to those of the C+ group. Multivariate analysis confirmed that the effects were most pronounced in the TE6.5 group, with complex interactions among the evaluated biomarkers.
