Contaminant transport refers to the movement of pollutants, chemicals, or other harmful substances through various mediums such as soil, air, and water. This area of research focuses on understanding how contaminants spread, interact with their environment, and impact human health and ecosystems. Researchers in this field study factors such as physical and chemical properties of contaminants, environmental conditions, and transport mechanisms to develop models and strategies for predicting and controlling the movement of pollutants. Contaminant transport research plays a crucial role in efforts to mitigate pollution, protect natural resources, and ensure public health and safety.
