TI  - Source and Distribution of Emerging and Legacy Persistent Organic Pollutants in 
      the Basins of the Eastern Indian Ocean.

AB  - Persistent organic pollutants (POPs) have received significant and ongoing 
      attention. To establish favorable regulatory policies, it is vital to investigate 
      the occurrence, source, and budgets of POPs worldwide. POPs including phthalic 
      acid esters (PAEs), organophosphate esters (OPEs), brominated flame retardants 
      (BFRs), and highly chlorinated flame retardants (HFRs) have not yet been examined 
      in the Eastern Indian Ocean (EIO). In this study, the distribution of POPs has 
      been investigated from surface sediments with the depth of 4369-5742 m in the 
      Central Indian Ocean Basin (CIOB) and Wharton Basin (WB) of EIO. The average 
      (+/-SD) concentrations of  summation operator(11)PAEs,  summation operator(11)OPEs,  summation operator(4) BFRs, and  summation operator(5)HFRs were 1202.0 
      +/- 274.36 ng g(-1) dw, 15.3 +/- 7.23 ng g(-1) dw, 327.6 +/- 211.74 pg g(-1) dw, and 
      7.9 +/- 7.45 pg g(-1) dw, respectively. The high abundance of low-molecular-weight 
      (LMW) PAEs, chlorinated OPEs, LMW BDEs, and anti-Dechlorane Plus indicated the 
      pollution characteristics in the EIO. Correlation analysis demonstrated that LMW 
      compounds may be derived from the high-molecular-weight compounds. The monsoon 
      circulation, currents, and Antarctic Bottom Water may be the main drivers. POP 
      accumulation rate, depositional flux, and mass inventory in the Indian Ocean were 
      also estimated.
