多溴联苯(Polybrominated biphenyls,PBBs)是一种联苯类化合物,其氢原子被溴原子所替代,由于苯环取代位点和溴原子个数不同,PBBs 理论上共有209种同系物。PBBs因其出色的阻燃效果在纺织、塑料、建材等工业领域作为阻燃剂和塑料添加剂广泛使用。
PBBs具有典型持久性有机污染物(POPs)特征,化学性质稳定,进入环境中后很难降解,可在水体等介质中长期存在并积累富集,对生物体健康具有潜在危害。
2009 年,六溴联苯(PBB153)被列入第二批《关于持久性有机污染物的斯德哥尔摩公约》受控名单。尽管目前世界范围内已全面停止了PBBs的生产,但由于大量含多溴联苯产品的使用及处置,PBBs仍在环境介质中持续、广泛存在。
百灵威全新推出一系列多溴联苯单标及混标,产品定值准确、浓度高、稳定性好、多种浓度可选。
