Organophosphate flame retardants (OPFRs), a novel class of persistent pollutants, are widely distributed in the environment, and their potential health risks have garnered significant global attention recent years. Crayfish is popular freshwater crustacean product China primarily sourced from middle lower reaches Yangtze Rive. The purpose this study was investigate to determine OPFRs exposure levels, assess safety associated with crayfish consumption, explore bioaccumulation crayfish. Ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) employed analyze 7 common 106 samples 76 environmental samples. results revealed that were detected at high frequency 100% crayfish, triphenyl phosphate (TPP) being predominant pollutant found edible portions while also exhibiting secondary contamination within food chain. Monte Carlo modeling combined @risk risk assessment software demonstrated TPP present muscles had most substantial impact on effects, however, overall OPFR did not pose human health. Furthermore, analysis bioenrichment ability indicated predominantly accumulated these compounds parts surrounding water sources, particularly highlighting TPP's for bioaccumulation.
