多溴联苯醚(Polybrom inated Diphenyl Ethers,PBDEs)是溴代阻燃剂类化合物,常作为阻燃添加剂加入树脂、聚苯乙烯和聚氨酯泡沫等高分子合成材料中,广泛应用于塑料制品、纺织品、电路板和建筑材料等领域。PBDEs在环境中难降解,滞留时间长,具有较强的亲脂性,其健康危害日益成为全球性的环境污染问题。生物积 Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants. They are often used as flame retardant additives in polymer composites such as resin, polystyrene and polyurethane foam. They are widely used in plastic products, textiles, circuit boards And building materials and other fields. PBDEs are difficult to degrade in the environment, have long residence time and have strong lipophilicity, and their health hazards are increasingly becoming global environmental pollution problems.
