Brominated flame retardants are chemical compounds that contain bromine and are used to reduce the flammability of various materials, such as plastics, textiles, and electronics. They are commonly found in products like furniture, mattresses, and electrical devices to help prevent fires. These substances work by interfering with the combustion process, making it harder for flames to spread. However, concerns have been raised about their potential health and environmental impacts, leading to increased regulation and research into safer alternatives, such as phosphorus-based flame retardants and halogen-free materials.
