Limits and prospects of the “incremental approach” and the European legislation on the management of risks related to nanomaterials

Scientific uncertainty involved in evaluating potentially harmful properties of engineered nanoparticles complicates and hampers the implementation of proportionate regulative measures by legislators. The European Commission has adopted a so-called “incremental approach”, which focuses on adapting existing laws to regulate nanotechnologies, and therefore this paper aims to test the effectiveness of the “incremental approach”. Three commercially available products containing fullerenes (C60 and carbon nanotubes) were analysed in a life cycle perspective in order to (1) map current applicable regulations, (2) analyse their applicability to nanomaterials, (3) identify their gaps, and (4) suggest proper solutions. mapping the life cycle of the three products, we analysed applicable regulations in the order in which they became relevant in their life cycle, i.e.:• fety at Workplace Directives, ive 61/1996 on the Integrated Pollution Prevention and Control, ropean Union’s Directive on the Registration, Evaluation, Authorization and Restriction of Chemicals, and ste Management Directives. found that the applicability of environmental laws is limited due to difficulties in generating sufficient data on the nanomaterials residing in the products according to their life cycles. Further, metrology tools are unavailable; thresholds are not tailored to the nanoscale; and toxicological data and occupational exposure limits cannot be established with existing methodologies. We conclude that the “incremental approach” can only be applicable with the implementation of due amendments.
