Most wild animals are likely to be exposed to low doses of trace metals throughout their lives; however, whether such chronic exposure affects fitness-related traits in natural populations remains to be investigated. In this study, we tested the relationships between trace metal burden and sex hormones, primary and secondary sexual traits in wild male roe deer. Using samples collected from 71 hunted males, we measured the hair and liver concentrations of various toxic trace metals, faecal testosterone metabolites (FTM), testis mass and antler length. We focused on cadmium (Cd), cobalt (Co), nickel (Ni) and lead (Pb) in roe deer tissues. Using linear (mixed effects) models, we found that Cd and, to a lesser extent, Co concentrations in the liver, but not in hair, were negatively associated with absolute testicular mass, a proxy of sperm production. However, metal burden, measured in either the liver or hair, was not related to antler length or FTM levels, despite their respective roles in male competitiveness for access to females and the underlying adjustments for seasonal breeding. Hence, our findings highlight the consequences of exposure to Cd and Co on male testicular function in a wild ungulate. Any alteration in male competitiveness for fertilization is expected to have lasting fitness consequences, which could subsequently alter population dynamics.</div></div>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"383 ","pages":"Article 126825"},"PeriodicalIF":7.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 organic contaminants such as benzotriazole UV stabilizers (BUVs), phthalates, polycyclic aromatic hydrocarbons (PAHs), bisphenol A (BPA), and antioxidants in beach and ocean plastics collected from multiple geographic locations. A validated analytical method comprising solid-liquid extraction followed by gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography with UV detection (HPLC-UV) was employed for contaminant identification. Some detected compounds have been classified as persistent organic pollutants and substances of very high concern, including di(2-ethylhexyl) phthalate (DEHP) and UV-328. The highest levels of UV-328 detected in both ocean and beach plastics samples (1040 ± 22 μg/g and 5188 ± 65 ng/g respectively) exceeded permitted limits in plastic as set by European Chemicals Agency (ECHA). Other contaminants such as chrysene (558 ± 3 ng/g), BPA (100 ± 1 μg/g) and antioxidant degradation products like tris (2,4-ditert-butylphenyl) phosphate were also detected in some marine plastic samples. Based on these findings, this study highlights the widespread occurrence of organic contaminants in marine plastics and their potential implications for second-life applications and environmental risk. These contaminants may also impact marine ecosystems through leaching and bioaccumulation, with possible consequences for human health via the food web. Overall, the study offers insights into informing policies on plastic waste management, recycling practices, and environmental protection measures aimed at mitigating the chemical hazards associated with marine plastic pollution.</div></div>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"383 ","pages":"Article 126827"},"PeriodicalIF":7.6,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 aims to examine the associations of PFAS with ALT and AST, and the mediating role of cytokines in healthy children. A panel study was carried out using three repeated measurements of 11 plasma PFAS, serum ALT and AST, and 48 cytokines among 134 children in Wuhan, China. Linear mixed-effect models, Bayesian kernel machine regression, and weighted quantile sum regression were used to explore the individual and combined associations of PFAS with ALT and AST. The mediating function of cytokines in these associations was assessed using causal mediation analysis. Perfluorononanoic acid (PFNA), perfluorohexane sulfonate (PFHxS), perfluoroundecanoic acid (PFUnDA), and perfluorododecanoic acid (PFDoDA) were found to have dose-response relationships with elevated ALT. PFAS mixture was associated with increased ALT in two mixed exposure models, with PFHxS identified as the major contributor. Such associations of PFAS and ALT were more evident in children who were overweight or obese and consumed fish ≥1 day/week. An integrated analysis revealed a group of children with elevated ALT levels, characterized by high PFAS exposure and increased cytokine levels. Four cytokines, including CCL 4, CCL27, IL-2Rα, and IL-9, were found to be associated with elevated levels of PFNA, PFHxS, PFUnDA, and ALT. Among them, CCL27 and IL-9 mediated 8.96 % and 12.06 % of the association of PFHxS with ALT, respectively.

Results indicated that long-term submerge-emerge alternation greatly enhanced PFAS release from contaminated sediments and their migration into aqueous phases. In the ASE group, the ∑PFAS concentration in sediment decreased to 437.8 μg/kg dw, a reduction of 66.32 %, compared with 774.93 μg/kg dw in the CS group, representing a decrease of 40.39 %.

The decreased presence of protein and CHOS formula compounds reduced co-adsorption, and the increased abundance of carboxyl and hydroxyl groups intensified competitive adsorption between PFASs and DOM could be the potential mechanism by which long-term submerge-emerge alternation affected sediment PFAS release.

Although the neurotoxicity of certain NEOs has been established, the potential neurotoxicity of the remaining large fraction of NEOs, as well as their underlying mechanisms, are yet to be clarified. In the present study, we employed a high-throughput toxicity screening platform to evaluate the neurotoxic potential of eight commonly used neonicotinoid insecticides in <em>Caenorhabditis elegans</em>. Our results revealed that acetamiprid (ACE), dinotefuran (DIN), clothianidin (CLO) and thiacloprid (THI) significantly impaired locomotion behavior in worms. Upon examining the potential mechanism of action, we found that ACE, CLO and THI could induce serotonergic neuronal damage, while cholinergic, dopaminergic and GABAergic neurons remained unaffected. Additionally, these three NEOs reduced bend frequency by predominantly enhancing oxidative stress, which was partially mitigated by the antioxidant N-acetyl-L-cysteine. In the neurotransmitter system, ACE mainly upregulated the mRNA expression of synthesis- and transport-related genes of neurotransmitters, while THI increased transport-related gene expression and decreased GABAergic receptor gene expression. In contrast, DIN elevated total acetylcholine levels without significantly altering gene expression, suggesting a distinct mechanism. In summary, our findings highlight that ACE, CLO and THI exert neurotoxicity through oxidative stress and serotonergic neuronal damage, while DIN primarily disrupts the neurotransmitter system.
