A growing number of new organic contaminants of potential environmental concern are constantly discharged into terrestrial and aquatic ecosystems in industrialized regions, and have the potential to bioaccumulate and be toxic to the most susceptible wildlife species such as birds. This may be the case for the numerous emerging halogenated flame retardants (HFRs) for which no national or international regulations exist despite their massive usage in a wide range of consumer and industrial products (e.g., cars, electronic circuitry, upholstered furniture, construction materials, etc.) to achieve fire safety standards, that is, to slow down the spread of fire. A recent study conducted by my research group reported unexpectedly high concentrations of the HFR class polybrominated diphenyl ethers (PBDEs) as well as several as yet undetected emerging HFRs in tissues of a urban-adapted avian species, the ring-billed gull (

在工业化地区，越来越多具有潜在环境问题的新的有机污染物不断被排放到陆地和水生生态系统中，并有可能发生生物累积，对鸟类等最易受影响的野生物种有毒。这可能是许多新兴的卤化阻燃剂（HFR）的情况，尽管它们在广泛的消费品和工业产品（例如，汽车、电子电路、软垫家具、建筑材料等）达到消防安全标准，即减缓火势蔓延。我的研究小组最近进行的一项研究报告说，在一种适应城市生活的鸟类--环嘴鸥（
