TI  - Chlorinated pesticides and PCBs in the sea-surface microlayer and seawater 
      samples of Singapore.

AB  - Sea-surface microlayer (SML) and seawater samples collected from Singapore's 
      coastal marine environment were analyzed for selected chlorinated pesticides and 
      polychlorinated biphenyls (PCBs). The SML is a potential site of enrichment of 
      persistent organic pollutants (POPs) compared to the underlying water column. The 
      concentration ranges of SigmaHCH, SigmaDDT and SigmaPCB in subsurface (1 m depth) 
      seawater were 0.4-27.2 ng/l (mean 4.0 ng/l), 0.01-0.6 ng/l (mean 0.1 ng/l) and 
      0.05-1.8 ng/l (mean 0.5 ng/l) respectively. In the SML, the concentration ranges 
      of SigmaHCH, SigmaDDT and SigmaPCB were 0.6-64.6 ng/l (mean 9.9 ng/l), 0.01-0.7 
      ng/l (mean 0.2 ng/l) and 0.07-12.4 ng/l (mean 1.3 ng/l) respectively. High 
      spatial and temporal distribution was observed for all POPs measured. However, 
      overall levels measured in the SML were lower than levels reported in the 
      literature for SML samples from temperate coastal regions-possibly due to loss of 
      semi-volatile compounds in the tropical climate of Singapore. Atmospheric wet 
      deposition during the monsoon season may be an important source of POPs to the 
      SML. This study provides the first scientific data on POP concentrations and 
      enrichment factors in the SML for Southeast Asia.
