AB  - The current study was conducted in the Cua Dai estuary, Vietnam, (1) to assess 
      the status of persistent organic pollutants (POPs) and (2) to examine the 
      interactive effect of season and estuary position on the concentration of the 
      pollutants in surface water and sediment. Fifty-two water and sediment samples 
      were taken in the dry and rainy seasons from inner- and outer-estuary positions 
      to analyze for six POPs, including hexachlorocyclohexane isomers (HCHs), 
      dichlorodiphenyltrichloroethane and its metabolites (DDTs), heptachlor, aldrin, 
      dieldrin, and polychlorinated biphenyl (PCBs). The averaged concentrations of the 
      respective POPs in water samples were 0.07, 0.1, 0.01, 0.03, 0.001, and 0.2 mug 
      L(-1) and in sediment samples were 2.6, 3.1, 0.9, 0.2, 0.2, and 121 mug kg(-1). Of 
      the six POPs examined, the concentration of DDTs in sediment samples and PCBs in 
      water samples was significantly affected by the interactive effect of the two 
      examined factors. The concentrations of HCHs, DDTs, heptachlor, and aldrin in 
      water samples and of HCHs in sediment samples were significantly higher in the 
      rainy season than in the dry season. Sediment samples collected from the inner 
      position had a significantly higher concentration of HCHs and PCBs than in the 
      outer position. Some mechanisms possibly influenced the varying POP concentration 
      could include (1) greater riverine discharge in the rainy season and (2) the sea 
      dilution effect in the outer position. Therefore, the concentration of the 
      individual examined POPs in water and sediment in the Cua Dai estuary 
      significantly depended on either the season, estuary position, or their 
      combination.
