The large use of nanomaterials in several industrial processes drove the attention toward the potential health issues associated to their diffusion in the environment. However, since nanomaterials are characterized by a polidisperse particle size distribution, the human health risk induced by a nanoparticle (NP) contamination cannot be assessed through the ASTM procedure commonly used for chemicals. Toxicity...
