Triolein-membrane partition coefficient:

Processing of the triolein alone (i.e., without analyzing the LDPE as well) is not encouraged for a number of reasons. First of all, the LDPE constitutes a significant part of the total SPMD sorption capacity, in contrast to biota, where the sorption capacity of the non-lipid phase is often considered to be negligible. Data on membrane-lipid partition coefficients (/fmc) is very limited, but the available... 

Based on thermodynamic arguments, it has been suggested that octanol does not accurately represents fish lipids [81]. Lipid solubility has been proposed as an additional parameter based on the argument that lipids are more structured than octanol [82]. Partition coefficients with other solvents (triolein-water) and membrane vesicles are measured and related to as well as to BCF [32, 83, 84]. In general, these latter partition coefficients fairly correlate with Kq with systematic lower values at high These differences may lead to an apparently lower BCR The consequences are that overestimates bioaccumulation for very hydrophobic compounds.
