| Summary: |
This Dutch-language report attempts to determine temporary values for maximum exposure of workers to nanomaterials, in the absence of certain scientific data. Based on currently published reports, the report gives specific values for materials such as carbon nanotubes. It is emphasized, however, that these values may still be ultimately unsafe for workers once future research is conducted. |

| Summary: |
After the UK Royal Commission on Environmental Pollution noted in 2008 that toxicology information for nanomaterials is not often compared against the toxicity information for the same material in bulk form, the National Institute for Public Health and the Environment of the Netherlands undertook this report, which identifies specific properties of nanomaterials in an aquatic environment that cause differing toxicity characteristics. Currently, environmental risk of chemicals is calculated using the quotient of a predicted environmental concentration (PEC) and a predicted no-effect concentration (PNEC). While there is no cause to assume that this method is invalid for nanomaterials, there is uncertainty in accounting for nanomaterial-specific environmental behavior in assessing PEC and PNEC. Examination of nanomaterials in the aquatic environment reveals that traditional methods of toxicity estimation are insufficient, and the report suggests that nanomaterials be added to the "difficult substances" list within the European Chemicals Agency (ECHA) Guidance, which would permit special methods to be used for risk assessment. These methods are still under development and more information is required before accurate assessments can be made. |
