  Brominated flame retardants, such as polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs), are used in a variety of consumer electronic products, and several of these flame retardants are produced in large quantities.Exposure to these materials might be more harmful than previously thought.Some PBDE congeners have dioxin-like effects, interfering with the aryl hydrocarbon (Ah)-receptor.Other PBDE congeners have hepatotoxic and mutagen effects.The International Agency for Research on Cancer also suggested PBBs may be carcinogenic to humans.Besides the environmental samples, they have been detected in a wide variety of food, such as marine fish, shellfish, tea and milk samples, which is more harmful to the human beings.Thus, it is necessary to detect the brominated flame retardant residues in food.
