Brominated flame retardants are the mostly widely used flame retardant in the world because of its effectiveness and low cost.

Polybrominated diphenyl ethers (PBDEs) are an important class of flame retardants, widely used in a variety of consumer products. In the past Eliminating most uses of PBDE flame retardants is possible, and a prudent step to protect public health. Concerns about rising levels of PBDEs in the breast milk of PBDEs: Information for Pediatric Health Professionals. 1.
