A more optimistic vision

In this context of uncertainty, Marc Wiesner (Duke University) notes that the methods used for the production of nanomaterials have often become greener during their passage from the laboratory to the site of industrial production. Their use could turn out to be relatively less toxic than the classic chemistry because of the reduction in the use of solvents and the level of waste production.

The safer by designapproach is presented as a “nano” risk assessment alternative provided until now but based on currents scientific knowledge, it's not possible to ensure that this approach may constitute an absolute guarantee against nanomaterial risks.


What will be the balance risks/benefits?

It thus seems that the use of nanoparticles, can be a beneficial technology for the environment, particularly for the treatment of waters, but could also be harmful due to the various entrances in the environment.
