Polybrominated diphenyl ethers (PBDEs) are a group of chemical compounds used as flame retardants in various products, including furniture, electronics, and textiles. They help reduce the risk of fire by slowing down the spread of flames. However, PBDEs can accumulate in the environment and in living organisms, raising concerns about their potential health effects. Due to their persistence and toxicity, many countries have started to regulate or ban the use of certain PBDEs. Research has linked these compounds to various health issues, including hormonal disruption and developmental problems in children. Efforts are ongoing to find safer alternatives to PBDEs in consumer products.
