GHS classification of nanomaterials

DHI and the Nordic Council of Ministers recently published an exciting report in which we have investigated whether GHS classification is applicable to nanomaterials.

DHI and the Nordic Council of Ministers recently published an exciting report in which we have investigated whether GHS classification is applicable to nanomaterials.

In general, we found that the GHS classification criteria are applicable to the four engineered nanomaterials analysed. The nanomaterials were selected to represent differences with respect to chemical composition, shape, water-solubility, specific surface area and density.

However, we also identified several critical issues using the GHS classification criteria on engineered nanomaterials. For voluminous nanomaterials, for instance, it may not be technically feasible to test dose levels that correspond to mass/weight-based classification criteria. This issue is especially related to the hazard categories for acute inhalation toxicity and specific target organ toxicity (STOT RE - inhalation)

As of 1 January 2020, new rules come into effect in the EU which is expected quite significantly to increase the amount of data for nanomaterials.
