Nanotech risk and safety

The implementation of nanotechnology poses unknown risks which are difficult to assess with respect to their impact on the environment, human health, ethical, legal and societal issues. Nanomaterials are already released into the environment because of their small dimensions nanomaterials can be largely distributed within the environment in water streams, soil and air. The absorption of nanoparticle in human body is mediated through skin, lung, gastro-intestinal tract. They are distributed within the whole organism via blood and lymphatic systems. Also ideals like toxic particles that can go everywhere and self-replicating nanorobots can produce fear and uncertainty in the broad public and can lead to severe societal problems.
