Abstract
The extent of binding($K_B$) between chemical compound and humic acid was measured as an indicator of decrease in toxicity. From the experimental $K_B$ and estimated $K_B$ calculated from $K_{ow}$, no reduction of toxicity among test chemicals in aquatic systems were predicted except P,P'-DDT. The effect of humic acid on aquatic organisms is not expected to be significant for the compounds with $K_B{\leq}10^5$ or $K_{ow}{\leq}10^6$.
