摘要： OPEs represent a class of novel persistent environmental pollutants. Crayfish (Procambarus clarkii) are popular freshwater crustacean products among consumers, with the Jianghan Plain being a major production area. The objective of this study was to investigate the exposure levels of OPEs in crayfish from the Jianghan Plain, to assess the health and safety risks associated with the consumption of crayfish, and to explore the bioaccumulation effects of OPEs in sediments on crayfish. The results revealed that the detection rate of OPEs in crayfish was as high as 100 %, with triethyl phosphate (TEP) being the predominant contaminant in crayfish. Monte Carlo simulations conducted that the exposure to OPEs through the consumption of crayfish abdominal muscle does not pose a significant risk to human health. Additionally, the analysis of the bioaccumulation capacity of OPEs showed a considerable correlation between the concentration of OPEs in crayfish and their levels in sediments.
