TI  - Polystyrene plastic: a source and sink for polycyclic aromatic hydrocarbons in 
      the marine environment.

AB  - Polycyclic aromatic hydrocarbons (PAHs) on virgin polystyrene (PS) and PS marine 
      debris led us to examine PS as a source and sink for PAHs in the marine 
      environment. At two locations in San Diego Bay, we measured sorption of PAHs to 
      PS pellets, sampling at 0, 1, 3, 6, 9, and 12 months. We detected 25 PAHs using a 
      new analytical method with comprehensive two-dimensional gas chromatography 
      coupled to time-of-flight mass spectrometry. Several congeners were detected on 
      samples before deployment. After deployment, some concentrations decreased 
      (1,3-dimethylnaphthalene and 2,6-methylnaphthalene), while most increased 
      [2-methylanthracene and all parent PAHs (PPAHs), except fluorene and 
      fluoranthene], suggesting that PS debris is a source and sink for PAHs. When 
      sorbed concentrations of PPAHs on PS are compared to the five most common 
      polymers [polyethylene terephthalate (PET), high-density polyethylene (HDPE), 
      polyvinyl chloride (PVC), low-density polyethylene (LDPE), and polypropylene 
      (PP)], PS sorbed greater concentrations than PP, PET, and PVC, similar to HDPE 
      and LDPE. Most strikingly, at 0 months, PPAHs on PS ranged from 8 to 200 times 
      greater than on PET, HDPE, PVC, LDPE, and PP. The combination of greater PAHs in 
      virgin pellets and large sorption suggests that PS may pose a greater risk of 
      exposure to PAHs upon ingestion.
