The grounds

What are probable scenarios for nanoparticles in the grounds?

According to their size, nanoparticles can be more or less strongly adsorbed on the particles of the ground by surface effects. The migration in the ground of the nanoparticles depends on their properties, on the physical characteristics of the ground, and on climatic. Besides, these particles become vectors by fixing the other substances.

Nanoparticles migration and types of ground.

The particle size and the structure (assembly) of particles condition:

  • the specific porosity of the ground: percentage of the volume of empty space,
  • its permeability: capacity to allow water to go through it under the influence of a pressure gradient.

On the other hand the solubility, the reactivity and the chemical stability of particles influence their mobility.
