摘要:溴代阻燃剂多溴联苯醚(PBDEs)是一类在各类环境介质、生物体和人体中均能检出的普遍存在的环境污染物。我国的主要污染源之一集中于东南部地区的电子废弃物回收场地。由于PBDEs具有结构稳定性、亲脂性和生物累积性，电子废弃物拆解回收活动对当地生态系统和居民健康存在着巨大的潜在风险。PBDEs的发育神经毒性受到研究者的极大关注，但其神经行为毒性效应和机制仍需深入研究。行为学效应既是内在神经毒性机制的外在反映，也是推测环境污染物在高级别生物学水平(如种群、群落)影响的最有力试验手段。近年来，基于视频追踪系统技术的商业行为学分析设备迅速发展，使行为学效应测试在环境毒理学领域具备极大的潜力。本文结合近年来国内外环境毒理学研究进展，回顾了PBDEs的神经行为毒性效应，包括运动行为、掠食行为和认知行为，并分析了其可能的毒理机制，最后总结了当前研究存在的问题和未来研究需要关注的重点方向。

Abstract:Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants (BFRs), have been recognized as ubiquitous environmental pollutants existing in a wide variety of environmental matrixes, biota and even human. One of the main pollution sources of PBDEs in China is coming from E-waste recycling sites located in southeast region. Due to the high stability and lipophilicity, PBDEs could be highly accumulated in biota, and therefore E-waste recycling activities has posed potential ecological and health risk to the local environment and residents. The developmental neurotoxicity of PBDEs has received great concern. However, the potential neurobehavioral toxicity and the underlying mechanisms are still barely known. Behavioral assay reflects the direct responses of neurotoxicity, which can even serve as a powerful tool to assess the potential toxicity at population and community level. In recent years, a commercial available video-tracking technique for behavior analysis is undergoing rapid development, which can strongly benefit the quantification of animal behavior in environmental toxicological studies. In the present review, we tried to summarize the worldwide research progress on environmental toxicology in recent decades, especially focusing on the neurobehavioral toxicity of PBDEs, including locomotion activity, predation activity and cognitive behavior. We further tried to explore the underlying mechanisms of those observed toxicity, and summarize the current knowledge gaps and the key issues in future toxicological studies.
