Different aquatic communities, although apparently equivalent, can exhibit a variety of responses when challenged with the same initial total toxicant concentration. Differences in realized actual exposure concentrations can result from differences in physical morphology, water and sediment chemistry, and physical transport processes. Seasonal differences in climatology and biological community structure also alter ecosystem responses. Simulation models and comparative studies provide methods for extrapolation.
