2,2',4,4'-tetrabromodiphenyl ether (BDE-47) is a widely used brominated flame retardant belonging to persistent organic pollutants (POPs). After being released into the marine environment, BDE-47 can cause a range of toxic effects on marine organisms through bioaccumulation, biomagnification, and intergenerational transmission. These effects include lethality, impaired motility, photosynthetic toxicity, immune damage, liver toxicity, developmental impairments, and reproductive toxicity. This article reviews the latest research progress on the toxic effects and molecular mechanisms of BDE-47 mentioned above. The primary mechanisms underlying its toxicity include oxidative stress, DNA damage, cellular apoptosis, impaired metabolism, and activation of the MAPK signaling cascade.
2,2',4,4'-四溴二苯醚（BDE-47）是一种广泛使用的溴化阻燃剂，属于持久性有机污染物（POPs）。释放到海洋环境中后，BDE-47可通过生物累积、生物放大和代际传递对海洋生物造成一系列毒性影响。这些影响包括致死性、运动能力受损、光合毒性、免疫损伤、肝脏毒性、发育障碍和生殖毒性。本文综述了上述BDE-47毒性效应及分子机制的最新研究进展。其毒性的主要机制包括氧化应激、DNA损伤、细胞凋亡、代谢受损和MAPK信号级联激活。
