Watersheds serve as natural boundaries for studying the distribution and movement of pollutants within an ecosystem. These areas can accumulate pollutants from various sources, including agricultural runoff, industrial discharges, and urban stormwater. Toxicologists study watersheds to understand how these pollutants affect both the environment and human health. By analyzing the flow of water and the presence of chemicals within a watershed, researchers can predict the spread of toxic substances and develop strategies to mitigate their impact.
