AB  - Although the Himalayas act as a natural barrier, studies have demonstrated that 
      certain traditional persistent organic pollutants (POPs) can be transported into 
      the Tibetan Plateau (TP) through the mountain valleys. Herein, we selected five 
      mountain valleys in the Himalayas to investigate novel flame retardants (NFRs), 
      as representative novel POPs, their concentration, distribution, transport 
      behavior, potential sources and ecological risk. The results revealed that total 
      concentrations of 7 novel brominated flame retardants (NBFRs) ranged from 4.89 to 
      2853 pg/g dry weight (dw) in soil and from not detected (ND) to 4232 pg/g dw in 
      moss. Additionally, total concentrations of 10 organophosphate esters (OPEs) 
      ranged from ND to 84798 pg/g dw in soil. Among the NFRs, decabromodiphenylethane 
      (DBDPE) and tri-phenyl phosphate (TPhP) were the predominant compounds. NBFRs and 
      OPEs concentrations were slightly higher than those in the polar regions. The 
      correlation between different compounds and altitude varies in different areas, 
      indicating that the NFRs distribution in the mountain valleys result from a 
      combination of long-range transport and local sources. The ecological risk 
      assessment using risk quotient (RQs) revealed that TPhP and tris 
      (2-chloroisopropyl) phosphate (TCIPP) exhibited medium or high risks at some 
      sites. This study sheds light on the transport pathways and environmental 
      behaviors of the NFRs in the valleys and highlights the need for increased 
      attention to the ecological risks posed by OPEs in the TP.
