AB  - As an extremely complex group of persistent organic pollutants (POPs) candidates 
      in the Stockholm Convention, short chain chlorinated paraffins (SCCPs) have been 
      of extensive concern in recent years. In this study, nine bivalve and two 
      gastropod species were collected in 2009 to evaluate the spatial distributions 
      and potential factors influencing the bioaccumulation of SCCPs in mollusks in the 
      Chinese Bohai Sea. The concentrations of  summation operator SCCPs in the mollusks were in the 
      range 64.9-5510 ng/g (dry weight) with an average chlorine content of 61.1%. 
      C(10) and C(11) were the predominant homologue groups of SCCPs, which accounted 
      for about 29.7% and 34.9% of  summation operator SCCPs, respectively. Six and seven chlorinated 
      substituents were the main congener groups. Mya arenaria (Mya), Mactra 
      veneriformis (Mac), and Crassostrea talienwhanensis (Oyster, Ost) had higher 
      average concentrations of SCCPs than other species, implying that these bivalves 
      could be used as sentinels to indicate SCCPs contamination in this coastal 
      region. A significant positive linear relationship was found between SCCP 
      concentrations and lipid content of the mollusks, whereas the lipid-normalized 
      SCCP concentrations were negatively linear-related to the trophic levels (TL), 
      which implied that SCCPs did not show biomagnification in mollusks in this 
      region.
