AB  - To date no passive sampler has been used to predict bioavailability of 
      contaminants to macrophytes. Here a novel passive sampler, linoleic acid embedded 
      cellulose acetate membrane (LAECAM), was developed and used to in situ measure 
      the freely dissolved concentrations of ten polycyclic aromatic hydrocarbons in 
      the sediment porewaters and the water columns of two lakes in both winter and 
      summer and predict their bioavailability to the shoots of resident submerged 
      macrophytes (Potamogeton malainus, Myriophyllum spicata, Najas minor All., and 
      Vallisneria natans (Lour.) Hara). PAH sampling by LAECAMs could reach equilibrium 
      within 21 days. The influence of temperature on LAECAM-water partition 
      coefficients was 0.0008-0.0116 log units/ degrees C. The method of LAECAM was comparable 
      with the active sampling methods of liquid-liquid extraction combined with fDOC 
      adjustment, centrifugation/solid-phase extraction (SPE), and filtration/SPE but 
      had several advantages. After lipid normalization, concentrations of the PAHs in 
      LAECAMs were not significantly different from those in the macrophytes. In 
      contrast, concentrations of the PAHs in the triolein containing passive sampler 
      (TECAM) deployed simultaneously with LAECAM were much higher. The results suggest 
      that linoleic acid is more suitable than triolein as the model lipid for passive 
      samplers to predict bioavailability of PAHs to submerged macrophytes.
