Among marine mammals, cetaceans stand out as environmental sentinels due to their high trophic level, longevity, and ability to bioaccumulate lipophilic substances. This review explores the impact of environmental contamination on the hypothalamic–pituitary–adrenal (HPA) axis, a key endocrine system involved in stress responses, whose chronic dysregulation may lead to adverse health outcomes. Existing evidence suggests that environmental pollutants can interfere with the production and regulation of steroid hormones, such as glucocorticoids, aldosterone, and dehydroepiandrosterone sulfate, potentially triggering HPA axis dysfunction and prolonged stress responses. However, substantial knowledge gaps remain, particularly concerning free-ranging cetaceans, highlighting the need for integrated assessments that combine hormonal and contaminant analyses. The development and validation of non-invasive methods capable of providing physiological data without inducing additional stress are also paramount. Integrating endocrine biomarkers with ecotoxicological data may offer a comprehensive approach to assessing environmental health risks and supporting more effective conservation strategies.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"385 ","pages":"Article 144562"},"PeriodicalIF":8.1,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579192","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}

In cloud-free conditions, the target chemicals partition to one or more of the organic or aqueous phases of aerosols and the gaseous phase in air.

Most acids and bases shift strongly to the water phase under ionizing conditions (i.e., pH 0 for bases and pH 7 for acids. Adjustments to the modelling for an increased volume in the water phase and changes in the pH of aerosols under cloudy conditions results in the prediction that most of these chemicals will partition into water droplets (i.e. rain) at some pH value between 0 and 7. It is proposed that wastewater treatment plants are point sources for PPCPs and possibly PFAS, while agricultural applications are the source of pesticides.

We highlight eco-friendly synthesis techniques such as hydrothermal carbonization, chemical vapour deposition, and microwave-assisted methods, which enable the scalable production of high-performance nanomaterials with tailored properties.

The integration of metal oxides (e.g., ZnO, TiO<sub>2</sub>, Fe<sub>3</sub>O<sub>4</sub>) with CNMs enhances their functional performance through synergistic effects, improving photocatalytic activity, electrochemical stability, and sensing capabilities. We discuss their role in supercapacitors, biosensors, antimicrobial agents, and pollutant degradation, emphasizing mechanistic insights and structure-property relationships.
