6PPD is a widely used chemical in the manufacturing of tire rubber, known for its anti-degradant properties [1]. It transforms into a highly toxic compound called 6PPD-quinone (6PPD-Q), which has been identified as the cause of sudden coho salmon deaths in the Pacific Northwest [2]. The...
The toxicity of 6-PPD quinone (6-PPDQ) has been frequently detected. However, the possible transgenerational effects of 6-PPDQ remain largely unclear. Due to short life cycle and high sensitivity to environmental exposure, Caenorhabditis elegans is useful for study of transgenerational toxicology. ...
transportation, and production phases. In the face of the severe situation of global soil pollution, chemical oxidation technology has shown potential in the remediation of oil-contaminated soil. However, most
结果表明:随着防老剂6PPD用量的增大,子午线轮胎钢丝粘合胶的硫化速率呈增大趋势,抗硫化返原性能呈稍微下降趋势;老化前后钢丝帘线抽出力均呈提高趋势;防老剂6PPD用量为2.5份时,老化后钢丝粘合胶各项性能的变化率最小,耐老化性能最好;防老剂6PPD用量对钢丝粘合胶的动态力学性能有一定影响,防老剂6PPD用量为2.5份时,钢丝粘合...

6PPD-Q accepts photosynthetic electrons at the plastoquinone QB site in photosystem II (PSII) and the phylloquinone A1 site in PSI, leading to a sustained decrease in the carbon fixation of cyanobacteria after an ephemeral increase. This work revealed the specific mechanism by which 6PPD-Q ...
6PPD and 6PPD-Q have been detected in human urine with concentrations reaching nanomolar levels. However, their human adverse effects and toxic mechanism are not explicit. This study elucidated their lipid metabolism disruption effects on hepatic cells (HepG2) and revealed a potential molecular ...
6PPD and 6PPDQ were found to bioaccumulate in the liver in a dose-dependent manner. Moreover, a high dose of 6PPD and 6PPDQ exposure increased not only the liver weights but also liver triglyceride levels, indicating that 6PPD and 6PPDQ exposure induced hepatotoxicity in mice. Furthermore, ...
6PPD is used in tire rubber as an antioxidant and was shown to cause acute mortality of adult salmon (Oncorhynchus kisutch) in the US due to stormwater exposure (Tian et al., 2021). The median lethal concentration of this substance is as low as 0.8 μg/L. In the US study, 6PPD was...
