A pharmacokinetic model was used to predict the acute toxicity of weak electrolytes to fish as a function of pH. For weak acids, the model predicted that the toxic concentration‐pH profile was shifted to the right of the ionized fraction‐pH profile. The relative rates of uptake of ionized and nonionized species can be calculated using toxic concentration‐pH data.
