N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure. This practice extends the lifespan of products, including tires, by preventing cracking, aging, deterioration. However, environmental consequences waste generated during product use, particularly formation 6PPD-quinone (6PPD-Q) through reaction 6PPD with ozone, have raised significant concerns due their detrimental effects on ecosystems. Extensive research has revealed widespread occurrence its derivate 6PPD-Q various compartments, air, water, soil. The emerging substance been shown pose acute mortality long-term hazards aquatic terrestrial organisms at concentrations below environmentally relevant levels. Studies demonstrated toxic a range organisms, zebrafish, nematodes, mammals. These include neurobehavioral changes, reproductive dysfunction, digestive damage exposure pathways. Mechanistic insights suggest that mitochondrial stress, DNA adduct formation, disruption lipid metabolism contribute toxicity induced 6PPD-Q. Recent findings human samples, such blood, urine, cerebrospinal fluid, underscore importance further public health toxicological implications these compounds. distribution, fate, biological effects, underlying mechanisms environment highlight urgent need for additional understand address impacts

Transgenerational nanoplastic toxicity could be detected in Caenorhabditis elegans after exposure at the parental generation (P0-G); however, underlying mechanisms remain largely unclear. We aimed to examine role of germline nuclear hormone receptors (NHRs) controlling transgenerational polystyrene nanoparticles (PS-NPs) based on gene expression screening and functional analysis. Among NHR genes, daf-12, nhr-14, nhr-47 expressions were increased nhr-12 was decreased by PS-NPs (1 10 μg/L). alterations these four genes also induced RNAi caused resistance, whereas conferred susceptibility PS-NP toxicity. After exposure, ins-3, daf-28, ins-39 encoding insulin ligands, efn-3 Ephrin ligand, lin-44 Wnt as well their receptor (daf-2, vab-1, and/or mig-1), dysregulated nhr-47, nhr-12. Therefore, alteration certain NHRs mediate induction affecting secreted ligands offspring exposed organisms.

Plastic pollution, including micro- and nanoplastics, is a growing concern. Tyre-wear particles (TWPs) are the second largest source of microplastics in ocean following abrasion synthetic fibres. In addition to themselves, TWPs contain many harmful chemicals, 6PPD. This chemical reacts with atmospheric ozone forms toxic compound 6PPD-quinone (6PPDq), which poses danger aquatic life. There knowledge gap understanding risks associated combined toxicity nanoplastics (NPs) 6PPDq. The present study aimed investigate NPs 6PPDq on adult zebrafish using phenotypic (behaviour, histology) transcriptomic endpoints. Zebrafish were exposed four treatments: control (contaminant-free), 50 μg/L 6PPDq, 3 mg/L polystyrene (PS)-NPs, combination PS-NPs. We did not observe locomotory dysregulation NPs. However, we found significant hyperlocomotion this effect was even more substantial after co-exposure explores molecular mechanisms behind these effects, identifying genes neurotransmitters fatty acid metabolism that dysregulated by co-exposure. Transcriptomic analysis further showed both PS-NPs impacted cellular processes sterol biosynthesis, cholesterol metabolism, muscle tissue development. effects stronger co-exposed zebrafish, indicating heightened risk integrity mitochondrial dysfunction. These results highlight significance mixture when studying chemicals like
