The flame-retardant tris(2,3-dibromopropyl) phosphate (TDBrPP) was in the 1970s banned for uses in textiles that may be in contact with the skin, owing to strong suspicions that the substance was a human carcinogen. The substance is looked for but rarely detected in samples from the built and natural environments, but there are indications that TDBrPP is still in use. Here, we report the measurement of a polymer-water partition coefficient (K) for two types of silicone rubber (SR), allowing quantitative estimation of freely dissolved concentrations of TDBrPP by passive sampling in water. We found levels of 100 to 200 pg/L in two Arctic rivers that were sampled during a 2014-2015 survey of contamination using passive samplers in Norwegian and Russian rivers draining into the Barents Sea. We also report the widespread presence of other organophosphorus flame retardants in this survey of eight rivers that drain into the Barents Sea.
阻燃剂三（2,3-二溴丙基）磷酸酯（TDBrPP）在 20 世纪 70 年代因强烈怀疑其为人类致癌物而被禁止用于可能与皮肤接触的纺织品。尽管在建筑和自然环境的样本中很少检测到该物质，但有迹象表明 TDBrPP 仍在使用。在这里，我们报告了两种硅橡胶（SR）的聚合物-水分配系数（K）的测量值，允许通过在水中进行被动采样来定量估计 TDBrPP 的自由溶解浓度。我们在 2014-2015 年对巴伦支海入海口的挪威和俄罗斯河流进行的污染被动采样调查中，在两条北极河流中发现了 100 至 200pg/L 的水平。我们还报告了在对流入巴伦支海的八条河流的这项调查中，其他有机磷阻燃剂的广泛存在。
