ABSTRACT:
This study concerns the relation between hydrophobicity and bio-accessibility of environmental pollutants among protozoan Tetrahymena pyriformis, water flea Daphnia magna and fish Poecilia reticulata. The toxicological data of 55 chemicals in terms of 50% effect concentration was selected towards these three biological objects along with their hydrophobic potential (octanol-water partition coefficients (log Kow)). Overall, a significant correlation was achieved among all test systems with highest between Tetrahymena pyriformis and Poecilia reticulata (R = 0.93). The acute toxicity results revealed substantial difference in the sensitivity of the three test systems but at certain level of hydrophobicity (log Kow values 0.5 to 2.5), where all environmental pollutant have utmost ability to reach biological compartments as cytosole and target sites within the membranes, to interfere with normal cell functioning by effecting normal enzymatic activity and directly to biological macromolecules.
