Modeling Toxic Contaminants in an Aquatic Environment

Models are increasingly used to overview complex problems, and all problems related to the environment are complex problems due to the enormous number of many interacting components. Consequently, models attempt to capture the most essential components and processes related to a specific problem in a specific environment. Of course the model cannot contain all components and processes involved in a problem, but only the most important ones for the focal problem may be considered. If all processes were to be included the model would not meet the required simplification it would become the system itself.
