Concerns about human health promoted studies on the effects of those two chemicals on vertebrates, where they have been found to act as endocrine-disrupting chemicals (EDCs), thus affecting important biological functions under hormonal regulation (e.g. development and reproduction). While arthropods represent most of animal biodiversity and play crucial roles in aquatic and terrestrial environments, few studies have investigated DEHP and BPA effects on those organisms as compared to vertebrates. In this context, the present article aims at reviewing the known effects of DEHP and BPA on arthropods. DEHP and BPA affect various biological functions in arthropods, and could act at low doses and possibly induce long-term effects for organisms, but the mechanisms of actions of those chemicals in arthropods are still unknown. We discuss research gaps on this issue and ecotoxicology in arthropods in general: (1) the notion of DEHP and BPA as endocrine disruptors in arthropods; (2) the usefulness of behavioural studies in arthropods' ecotoxicology; (3) the need to better understand epigenetic mechanisms in arthropods and how chemicals could interfere with them; (4) the inclusion of the effects on arthropod's microbiota in ecotoxicological studies; and (5) the need to increase the use of integrative approaches, omics, modelling and adverse outcome pathways to better understand chemicals' mechanisms of actions in arthropods and the resulted adverse outcomes at population level.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 developed a titanium-coconut shell based minerals (Ti-CSM) composite for the simultaneous removal of bisphenol S (BPS), carbamazepine (CBZ), and clonazepam (CZP) from water. Carbon material produced with coconut shell-a low-cost biomass-was used as support for titanium oxide in varying mass/mass Ti/biomass ratios (25:75, 50:50, and 75:25), with the Materials being calcined at 400 °C and 600 °C.

The Ti-CSM 25:75 composite calcined at 600 °C achieved up to 99% removal for BPS and CZP, and 98.7% for CBZ under optimal conditions (pH 7.0, adsorbate/adsorbent ratio 2.5, and temperature 16 °C).

Nanoscale zerovalent iron (nZVI) and its carboxymethylcellulose-functionalized form (CMC-nZVI) are widely proposed for redox-based heavy metal remediation. However, the post-sequestration stability of immobilized metals, particularly under saline conditions, remains poorly understood. This poses critical risks to long-term treatment efficacy and environmental fate.
