AB  - Limited information is known about organophosphate esters (OPEs) in sediments of 
      the Dong Nai River System (DNRS) in Vietnam and the influences of complex 
      hydro-sedimentary dynamics on their fate. In this study, 48 surface sediment 
      samples were collected from the Dong Nai-Soai Rap River and its tributary Vam Co 
      River for the determination of 11 target OPEs, together with grain size and total 
      organic carbon (TOC). The total concentrations of OPEs were in the range of 
      39.4 ng/g dw-373 ng/g dw (mean: 128 ng/g dw), and tris(1-chloro-2-propyl) 
      phosphate (TCPP) was the predominant one with an average contribution of 81%, 
      followed by tri-n-butyl phosphate (TNBP), tris(2-ethylhexyl) phosphate (TEHP). 
      The composition profiles of OPEs at different locations of the DNRS showed no 
      significant differences (p > 0.05). In addition, the distribution of OPEs had 
      been influenced by both human activities and the fluvial-tidal interactions. The 
      highly frequent and various human activities in Ho Chi Minh City (HCMC) leaded to 
      the highest total concentration of OPEs in the midstream site. Based on our 
      dataset, TOC content and grain size of sediments had significant correlation with 
      certain OPEs (p < 0.05), and sediments with higher TOC content and finer grain 
      size in the DNRS were more likely to be deposited in the downstream reach, 
      contributing to the estuary of the DNRS was identified as another hotspot with 
      the second highest concentration of OPEs. Furthermore, the distribution of OPEs 
      in the transects had distinct characteristics, which reflected the joint 
      influence of the human activities and fluvial-tidal interaction as well. However, 
      the mechanism of their influence needed further investigation.
