Summary

The Danish Environmental Protection Agency (DEPA) has previously initiated projects which have highlighted the nanomaterials that can be found in products on the Danish market (Consumer Project No. 81), and the nanomaterials used in the Danish industry (Environmental Project No. 1206).

As a follow-up on these reports, the DEPA identified a need to try to develop a concept that can provide support to companies and regulators in regard to assessing, ranking and communicating what they know about the risks of nanomaterials in specific uses in products.

DEPA has therefore initiated this project in order to examine the possibilities for developing such a conceptual framework for screening of potential environmental and health risks for nanomaterials used in products.

The current project is one of the initiatives under the national action plan for Chemicals which also includes a survey on basic knowledge about exposure and potential environmental and health risks for selected nanomaterials (Environmental Project) and on carbon nanotubes (Environmental Project).

Through this project, DTU Environment and the National Research Centre for the Working Environment have initiated the development of a screening tool, NanoRiskCat (NRC), which is able to identify, categorize and rank exposures and effects of nanomaterials used in consumer products based on data available in the peer-reviewed scientific literature and other regulatory relevant sources of information and data. The primary focus was on nanomaterials relevant for professional end-users and consumers as, as well as nanomaterials released into the environment.

The wider goal of NanoRiskCat is to develop an easily comprehensible approach that - when fully developed and validated - can help manufacturers, down-stream end users, regulators and other stakeholders to make decisions in situations where the safety of nanomaterials are being questioned, and to evaluate, rank and communicate the potential for exposure and effects through a tiered approach in which the specific applications of a given nanomaterial are evaluated. This is done by providing detailed guidance on mapping and reporting of the:

1. Exposure potential for professional end-users

2. Exposure potential for consumers

3. Exposure potential for the environment

4. A preliminary hazard evaluation for humans

5. A preliminary hazard evaluation for the environment

In this report, before going into detail with NanoRiskCat, a systematic evaluation of existing ranking and assessment concept and frameworks for chemicals and nanomaterials will be performed (Chapter 2) in order to get inspiration from these. This is followed by a description of the overall structure of NanoRiskCat (Chapter 3) as well as the evaluation criteria used to assess the exposure potential of a given nanomaterial application and to evaluate the hazard profile of a specific nanomaterial. This includes two illustrative examples of using NanoRiskCat on specific nanomaterial used in consumer products or industry (Chapters 4) and a discussion about the potential use(s) and pros and cons of NanoRiskCat (Chapter 5).
