Ap. Vanwezel et A. Opperhuizen, THERMODYNAMICS OF PARTITIONING OF A SERIES OF CHLOROBENZENES TO FISH STORAGE LIPIDS, IN COMPARISON TO PARTITIONING TO PHOSPHOLIPIDS, Chemosphere, 31(7), 1995, pp. 3605-3615
Lipid/water partition coefficients for storage lipids from fish (K-d,K
-sl), were determined for a series of chlorobenzenes at three differen
t temperatures. K-d,K-sl values were higher than lipid/water partition
coefficients for phospholipids that were measured previously for the
same compounds. Based on results of the present study and studies repo
rted in the literature, it is concluded that fish lipids cannot be con
sidered as a uniform compartment, the distinct properties of the vario
us lipids result in different lipid/water partition coefficients. The
partitioning of chlorobenzenes between storage lipid and water is enth
alpy-driven. The entropy of the transfer from water to lipids is unfav
ourable for the tested compounds.
