TI  - Distribution and trophic transfer of short-chain chlorinated paraffins in an 
      aquatic ecosystem receiving effluents from a sewage treatment plant.

AB  - Short-chain chlorinated paraffins (SCCPs) are an extremely complex group of 
      industrial chemicals and found to be potential persistent organic pollutants 
      (POPs), and thus have attracted extensive concern worldwide. In this study, 
      influent, effluent, and sludge were collected from a large sewage treatment plant 
      (STP) in Beijing, China. Water, sediment, and aquatic species were also collected 
      from a recipient lake that receives effluents discharged from the STP. These 
      samples were then analyzed to investigate the effect of STP effluent on 
      distribution and trophic transfer of SCCPs in the local aquatic ecosystem. 
      Concentrations of total SCCPs (SigmaSCCPs) in lake water and surface sediments were 
      found in the range 162-176 ng/L and 1.1-8.7 mug/g (dry weight, dw), respectively. 
      Vertical concentration profiles of sediment cores showed SigmaSCCPs decreased 
      exponentially with increasing depth. Specific congener composition analysis in 
      sediment layers indicated possible in situ biodegradation might be occurring. 
      High bioaccumulation of SCCPs was observed in the sampled aquatic species. The 
      bioaccumulation factor (BAF) generally increased with the number of chlorines in 
      the SCCP congeners. A significantly positive correlation between lipid-normalized 
      SigmaSCCPs concentration and trophic levels (R(2) = 0.65, p < 0.05) indicate that 
      SCCPs can biomagnify through the food chain in the effluent-receiving aquatic 
      ecosystem.
