Sentence examples for diffusion of contaminants from inspiring English sources

Knowledge of the factors that influence the diffusion of contaminants, such as the diffusivity and the connected porosity, is crucial to modeling the long-term fate and transport of contaminants in subsurface systems with small or negligible advective flow, such as in fractured crystalline rock.

Diffusion of contaminants from fractures into the interconnected wall-rock porosity is an important retardation process in geosphere transport.
