Pollution Status and Research Outlook of New Brominated Flame Retardants in Tibetan Plateau Region
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 prob-lems in several studies,and in order to solve these problems,a series of new flame retardants(NBFRs),represented by deca-bromodiphenyl ethane(DBDPE),have emerged.As a kind of new pollutant,NBFRs have been reported in industrially devel-oped 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.Howev-er,few studies have been conducted on the Tibetan Plateau and further research is needed to fill the gap of new contaminants in the region.
