摘　　要：阻燃剂作为在工业上被广泛用作电子产品、汽车、聚氨酯泡沫、纺织品等消费品的添加剂,用于降低易燃材料着火的可能性。传统的阻燃剂如多溴联苯醚已在多项研究中证明存在环境污染和毒性问题,为了解决这些问题,以十溴二苯基乙烷(DBDPE)为代表的一系列新型阻燃剂(NBFRs)应运而生。作为新污染物的一种,NBFRs在环渤海地区、京津冀地区等工业发达区域和两极地区等偏远区域均有报道。青藏高原作为世界的第三极,工业化程度低,人迹罕至,与两极地区一样,是研究NBFRs大气长距离迁移与对环境影响的重要区域。文章综述了近年来青藏高原地区进行的NBFRs研究,包括土壤、苔藓、大气以及水体等介质,研究区域涵盖青藏高原的多个典型地区。在青藏高原已有报道中,DBDPE的浓度和检出率在各项基质中均为最高值。但当前在青藏高原进行的研究仍然较少,需要进一步研究,以弥补新污染物在青藏高原地区研究的空白。Flame retardants,widely used in industry as chemicals in additives for consumer products such as electronics,automobiles,polyurethane foams,and textiles,are used to reduce the likelihood of fire in flammable materials.Traditional flame retardants such as polybrominated diphenyl ethers have been proved to have environmental pollution and toxicity problems in several studies,and in order to solve these problems,a series of new flame retardants(NBFRs),represented by decabromodiphenyl ethane(DBDPE),have emerged.As a kind of new pollutant,NBFRs have been reported in industrially developed regions such as the Bohai Rim and Beijing-Tianjin-Hebei regions,as well as in remote regions such as the bipolar regions.As the third pole of the world,the Tibetan Plateau,with low industrialization and sparsely populated,is an important region to study the atmospheric long-range transport and environmental impacts of NBFRs,as is the case for the bipolar regions.In this paper,we summarize the NBFRs studies conducted in the Tibetan Plateau region in recent years,including soil,moss,atmosphere,and water media,and the study area covers a number of typical regions in the Tibetan Plateau.The concentration and detection rate of DBDPE have been reported to be the highest in all matrices on the Tibetan Plateau.However,few studies have been conducted on the Tibetan Plateau and further research is needed to fill the gap of new contaminants in the region.
