Abstract
A physical basis is sought for modeling the ecological effects of neutral, hydrophobic chemicals acting jointly. It is assumed that these chemicals cross biological membranes passively, driven by gradients in chemical potential, and are distributed among chemical phases (types of tissue) of an organism's body by equilibrium partitioning. On this basis, a model is developed to account for exchange of chemicals between the external aqueous medium and an organism's body.
