Analysis of the sources, toxicity, and control methods of polybrominated diphenyl ethers

As fire safety standards continue to rise in all sectors of society, flame retardants are increasingly being used as a key material, such as polybrominated diphenyl ethers (PBDEs). PBDEs have become a focus of public and environmental protection attention due to their difficult degradation, easy accumulation in the environment, and transfer through the food chain. This research will investigate the main sources of PBDEs and analyze in detail the migration, transformation and distribution patterns in water, atmosphere, soil and biosphere, with a view to providing a scientific basis for the subsequent environmental monitoring and management. In addition, the physicochemical properties of PBDEs which are directly related to their persistence and potential for bioaccumulation in the environment, will be systematically described. This research will delve into the specific human health hazards of PBDEs Given the hazardous nature of PBDEs, this research will propose a series of targeted strategies and measures aimed at mitigating or preventing their toxic effects.
