9. Transport of Pollutants - Introduction
The chapter discusses the transport of pollutants in various environmental systems, focusing on how concentration changes over time and space. It outlines the importance of modeling pollutant transport and validating these models through measurement techniques. Concepts such as mass balance equations, box models for rivers, and the complexities of steady-state systems are introduced to emphasize the analytical approaches for predicting concentration levels in different scenarios.
