Comparisons were made between the ecological effects of phenolic compounds measured in experimental ponds and the effects forecast by aquatic ecosystem models. The Standard WAter COlumn Model (SWACOM) was used to extrapolate acute toxicity data to estimated changes in production of phytoplankton, zooplankton, and forage fish in relation to oil exposure. Replacement of SWACOM by POND, a model structurally more similar to the ponds, resulted in more accurate forecasts of the observed patterns of change in biomass production of algae and forage fish, and the observed pattern of change in nutrient concentration. The combination of toxicity data measured for the water-soluble fraction of the oil, the measured concentrations of total phenolic compounds, and the POND model provided the most accurate forecasts of effects. 8 refs., 1 fig., 5 tabs.
