This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study of two case studies on modeling in ecotoxicological research. These case studies illustrate the inadequacies of present models to integrate important processes into a single model, and also discuss the experimental work necessary to find the important mechanisms of a process. The trend shows that many current models incorrectly neglect the physiological processes of the aquatic life. Although models have many limitations, they are still among the best tools for prediction available. Therefore, the effort to develop an accurate and tractable model is imperative. Furthermore, the complexity of the water systems and the integration of various properties necessitates the development of such models as an interdisciplinary project which integrates theoretical and experimental research.
