Risk assessment of all the ENMs in the market would require the sacrifice of enormous amounts of test organisms of diverse range [7

However, the risk estimations are derived from the available literature on the effects of nanomaterials but not on the actual risk assessment of the specific ENM-containing products. Therefore, the risk levels reported in the database do not account for concentrations or the
