Chemical transport refers to the movement of chemical substances within various environments, such as air, water, and soil. This process can occur naturally, through mechanisms like diffusion and convection, or be influenced by human activities, such as industrial emissions and agricultural runoff. Understanding chemical transport is essential for assessing environmental pollution and its impact on ecosystems. In the context of environmental science, chemical transport plays a crucial role in determining how pollutants spread and degrade over time. It helps scientists predict the behavior of substances like pesticides, heavy metals, and nutrients in different media, which is vital for effective management and remediation strategies.
