Due to their lipophilic properties, they accumulate in aquatic sediments, endangering epibenthic organisms such as planarians. We aimed to assess the sensitivity of <em>Girardia tigrina</em> to two organic UV filters, 2-hydroxy-4-methoxybenzophenone (BP-3, Benzophenone-3) and 4-methylbenzylidene camphor (4-MBC, Enzacamene), by evaluating mortality, behavioural activity, cephalic regeneration after decapitation, and biochemical endpoints. A 96-hour LC<sub>50 s</sub> of 1483 µg/L and 1653 µg/L were estimated for BP-3 and 4-MBC, respectively. Sublethal concentrations of both compounds impaired planarian cephalic regeneration; BP-3 induced a delay in auricles regeneration, while 4-MBC delayed both photoreceptors and auricles regeneration. Locomotion significantly decreased in planarians exposed to 4-MBC, while BP-3 exposure did not induce locomotion alterations in <em>G. tigrina</em>. Moreover, induced phase II detoxifying enzyme (measured through Glutathione-<em>S</em>-transferase activity) was also observed in 4-MBC exposure, possibly mitigating oxidative damage, while BP-3 exposure caused oxidative damage (increased lipid peroxidation levels). Exposure to both compounds led to a reduction in acetylcholinesterase activity, showing evidence of neurotoxicity. Even though this study reported deleterious effects in exposed <em>G. tigrina</em>, the concentrations at which effects were reported are still higher than those usually reported in the freshwater environment. However, we would like to emphasise the importance of such studies in supporting the regulation and environmentally safe use of sunscreen products.</div></div>","PeriodicalId":11775,"journal":{"name":"Environmental toxicology and pharmacology","volume":"121 ","pages":"Article 104899"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145697229","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}

Both PCP and TCHQ exhibit well-documented toxicities and have likely contributed to substantial occupational and environmental exposures worldwide, owing to their efficient absorption through multiple routes. While HCB, although not a PCP metabolite, similarly poses long-term toxicological risks. These toxicants exhibit distinct toxicological profiles, underscoring their relevance as environmental health hazards. Our previous studies have demonstrated that PCP exposure activates the Hsp70-ROS-autophagy axis in submerged lung alveolar epithelial (A549) monolayers, highlighting its role in initiating early cellular stress responses. Building on our prior investigations, this study evaluates the cellular mechanisms activated by PCP, its metabolite TCHQ, and the co-occurring pollutant HCB at a higher occupationally relevant concentration using submerged monolayer (2D) and 3D air-liquid interface (ALI) models. The computational insights from the STITCH-based network prompted us to validate these links in A549 cells exposed to PCP, TCHQ, and HCB. All tested compounds induced the expression of PANoptosis and RNA granule markers, alongside inflammatory cytokine/chemokine production, implicating integrated cell death pathways and post-transcriptional regulatory mechanisms jointly mediate cellular responses under these conditions. Remarkably, wound healing (in vitro scratch) assays indicated preserved epithelial cell migration capacity despite robust inflammatory and PANoptotic signaling, highlighting a dynamic balance between cellular stress and regenerative resilience. Overall, this study elucidates the role of PANoptosis and RNA granule dynamics as central mediators of toxicant-induced inflammation, providing a mechanistic framework for evaluating the cellular effects of chlorinated environmental pollutants such as PCP and related compounds.</div></div>","PeriodicalId":11775,"journal":{"name":"Environmental toxicology and pharmacology","volume":"121 ","pages":"Article 104862"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145441642","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}
