The impact of nanoparticles may be significant because of the potential for ([ 10 ], p. 44): bioaccumulation: due to their high mobility, nanoparticles can easily move in the air, water and soil, contaminate the fauna and flora and thus be transferred to the food chain; persistence: creating non-biodegradable pollutants, which will be hard to detect, might lead to an important waste problem—even though nanotechnologies are often presented as being intrinsically ecological.
