Pollutant transport is the academic field and methodological approach concerned with the movement and fate of substances considered detrimental to the environment or human health. It investigates the physical, chemical, and biological processes that govern the advection, diffusion, dispersion, and transformation of pollutants through various environmental media such as air, water, soil, and biological systems. Key areas of study include quantifying transport rates, identifying pathways, modeling spatial and temporal distribution, and understanding pollutant interactions, which are critical for environmental risk assessment, regulatory development, and remediation planning.
