ECHA Begins Consultation on Testing Proposal for Multi-Wall Carbon Nanotubes

On November 3, 2011, the European Chemicals Agency (ECHA) began a consultation on a testing proposal for multi-wall carbon nanotubes, synthetic graphite in tubular shape. Under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program, manufacturers and importers must obtain information on toxic effects of substances.  REACH requires that new testing of a substance involving vertebrate animals be carried out only as a last resort, however. ECHA states that, to ensure that the best use has been made of existing information, it publishes all test proposals involving vertebrate animals for endpoints specified in Annexes IX and X under REACH.  After a testing proposal has been published, third parties have 45 days to submit “scientifically valid information and studies that address the relevant substance and hazard endpoint, relating to the testing proposal.” The hazard endpoint for which vertebrate testing was proposed is long-term toxicity to fish. The deadline for submitting information is December 19, 2011. ECHA will consider any scientifically valid information and studies that address the relevant substance and hazard endpoint.  ECHA publishes its responses to these contributions for the testing proposals after adoption of the related final decision.

EC Publishes Final RIPoN Reports

The European Commission (EC) began in 2009 a Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Implementation Project on Nanomaterials (RIPoN), which it intended to provide advice on key aspects of the implementation of REACH with regard to nanomaterials. The EC recently posted final reports concerning nanomaterials and information requirements (RIPoN 2) and chemical safety assessment (RIPoN 3). The EC states that, based on the scientific and technical state of the art with regard to nanomaterials, the reports were developed so that the advice on specific issues related to nanomaterials can be integrated into the existing REACH guidance documents. The EC notes that “inclusion of any of the advice from the reports into the [European Chemicals Agency (ECHA)] guidance is exclusively the responsibility of ECHA.  The presented reports do not represent ECHA guidance.” Nevertheless, the EC states, “while awaiting the official guidance up-date, companies are invited to consult the two reports and take the recommendations into account as appropriate when preparing or updating REACH registration dossiers and evaluating hazard information for potential classification under CLP.” The EC also posted a third report on substance identity. The EC cautions, however, that since it was not possible to reach consensus amongst the experts on the recommendations in the third report, “further work of the Commission, in collaboration with CARACAL, is required before recommendations can be forwarded to ECHA.”

REACH Conference Participants Discuss Nanomaterials

During the September 23, 2011, Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) conference organized by the European Chemicals Agency (ECHA) and European Commission (EC), Astrid Schomaker, Directorate-General (DG) Environment, stated that the EC has been working on a definition of nanomaterials, and that it “should be coming after the summer.” The EC previously stated in a letter to the Dutch Environment Ministry that it would publish a definition by the end of June. Karl Falkenberg, Director-General for DG Environment, stated that the issue is “triangular -- we have to put together environmental, trade and health perspectives.” Conference delegates disagreed whether nanomaterials are appropriately addressed under REACH. According to Alexander Nies, Deputy Director-General for Germany’s Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, ECHA has found only three cases where substances qualify as nanomaterials, even though there are “more than 900 companies in Germany that produce nanomaterials.” Nies urged the EC to adapt REACH to deal with the specific features of nanomaterials. Adrian Harris, Director-General for the European Engineering Industries Association, responded that the Association supports “rationalization” rather than increasing demands under the registration process. Harris stated that “REACH in its present form is fit to address nanotechnology.”

ECHA Preparing Nano Inventory from REACH and CLP Submissions

The European Chemicals Agency (ECHA) is compiling an inventory of nanomaterials included in the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) registration dossiers and Classification, Labeling, and Packaging (CLP) notifications for the European Commission (EC), and intends to deliver the inventory by the end of June 2011. The EC requested the inventory in response to the 2009 European Parliament communication on nanomaterials. An ECHA spokesperson stated that detailed results from the inventory would be available towards the end of 2011, and the inventory may be disseminated at a later date, but this has not yet been discussed. According to the spokesperson, ECHA has found three registration dossiers and 14 CLP notifications in which “nanomaterial” was selected as the form of the substance. The spokesperson stated that ECHA will be able to identify 50-60 REACH registration dossiers that include information on nanomaterials that will be sent to the Joint Research Centre for assessment under a separate project to address if and how information on nanomaterials is included in REACH registration dossiers.

Dutch Urge EU to Act on Nanomaterials

In February 2011, the Dutch Environmental Safety and Risk Management Directorate sent a letter to the Directorate General (DG) Enterprise and DG Environment expressing concern regarding delays in the work of the Competent Authorities Sub-Group on Nanomaterials (CASG Nano) and the European Commission’s (EC) progress regarding clarifying the definition and status of nanomaterials. The Dutch Directorate states that an essential first step is to define what nanomaterials are and asks that the EC propose a common definition to member states as soon as possible, and in time for it to be discussed at the Competent Authorities for REACH and Classification and Labeling (CARACAL) meeting scheduled for mid-2011. According to the Directorate, the definition should be sufficiently broad to ensure all substances that present a nano-related risk are covered. The Directorate also asks that the three Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) implementation projects on nanomaterials be completed before the CARACAL meeting and that the EC provide greater clarity on the criteria necessary to assess whether nanomaterials pose specific risks. The Dutch competent authority is considering which substances to propose for substance evaluation under REACH and intends to include a nanomaterial. While the evaluation would not begin until 2012, the Dutch competent authority states that it would still be valuable to provide information on which elements of REACH remain problematic in terms of assessing hazards and risks associated with nanomaterials.

ECHA Publishes Technical Manual for Including Nanoforms in an IUCLID Dossier

On June 11, 2010, the European Chemicals Agency (ECHA) announced the availability of a technical manual for including nanoforms in an International Uniform Chemical Information Database (IUCLID) dossier. The Nanomaterials in IUCLID 5.2 Industry User Manual “gives practical instruction to [Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)] registrants on how to include information on different forms of a substance in a IUCLID 5.2 dossier.” The Manual introduces a book-keeping principle, where each form gets a specific label that enables it to be tracked throughout the dossier. Instructions are given on how to create labels for form-specific reference substances, composition blocks, endpoint study records, and analytical data. In particular, the Manual “gives instructions that will enable registrants to consistently create and label Endpoint study records such that it is clear which composition or form was used as the test substance for that study.”

The Manual states:

Nanomaterials are covered under the substance definition in REACH and may be considered to be distinct substances or forms of a substance (CA/59/2008). The sole purpose of this document is to provide registrants with information on how to technically prepare their IUCLID dossiers for nanomaterials. It is the responsibility of the registrant to identify the substance and this document does not provide any information that will aid the registrant deciding when a nanomaterial can be considered to be a distinct substance or a nanoform. Moreover, following the technical advice given in this document does not imply that a dossier would be compliant with REACH requirements should it be selected for evaluation.

The Manual notes that, although there are no specific information requirements for nanomaterials under REACH, it encourages registrants “to include any information they consider relevant to better describe the substance and to demonstrate its safe use.” The Manual suggests that registrants take advantage of the preliminary guidance of the Organization for Economic Cooperation and Development (OECD) Working Party on Manufactured Nanomaterials (WPMN) on testing, exposure measurements, and mitigation of nanomaterials.

 

ECHA Revising REACH Guidance Documents to Include Nanomaterials

During the Helsinki Chemicals Forum 2010, Jukka Malm, European Chemicals Agency (ECHA) Assessment Director stated that ECHA is revising its Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) guidance documents to include technical instructions to help companies include nanomaterials in their registration dossiers and other compliance obligations for substances they make or import. According to Malm, ECHA is following “international developments,” particularly work by the Organization for Economic Cooperation and Development (OECD) concerning nanomaterial safety and testing. Malm stated: “As results become available, we are trying to introduce them into our guidance documents for steering industry on how to implement REACH in practice in their registration dossiers and other obligations.”

EC Will Review Legislation to Ensure Safety of Nanomaterials

In an October 9, 2009, speech at the stakeholder conference concerning nanomaterials on the market, Stavros Dimas, European Commissioner for the Environment, stated that the European Commission (EC) “will review all relevant legislation within two years to ensure safety for all applications of nanomaterials in products with potential health, environmental, or safety impacts over their life cycle.” The EC’s review is in response to an April 24, 2009, resolution adopted by the European Parliament that questions whether current legislation covers the relevant risks relating to nanomaterials and asks the EC to consider whether revisions are necessary to address nanomaterials.  Dimas stated that the EC “has not made up its mind on how precisely to get the information needed.” The EC intends to look at measures taken by member states and non-European Union (EU) countries, including voluntary reporting programs.

Dimas examined whether the existing regulatory framework of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program is sufficient to ensure “a high level of protection of health, safety and the environment” from nanotechnology products. Dimas stated that nanomaterials are covered by REACH under the definition of a chemical substance, and the general obligations therefore apply as for any other substance. According to Dimas, the “important” question to ask is whether the one tonne threshold used by REACH is appropriate for nanomaterials. Dimas stated:

Once we have a better idea of the scope and nature of nanomaterials on the European market we can then take a step back and go through the rules.  We will need to consider whether registration of the majority of nanomaterials will take place in 2010 or only at the end of the registration timetable in 2018 and if there are some nanomaterials that will not be registered under REACH.  We will also need to look at other key provisions in REACH to see if they are adequate for nanomaterials.

Norway Asks Businesses to Report Presence of Nanomaterials

On June 25, 2009, the Norwegian Board of Technology announced that the Norwegian Pollution Control Authority (SFT) has established “a scheme for Norwegian businesses to report their use of nanomaterials in chemical products.”  According to a spokesperson for the Board, until now the Norwegian market has “lacked oversight of nanomaterials.”  Under the scheme, information about nanomaterials in chemical products will be incorporated as a separate topic in declarations to the Norwegian Product Register, which is administered by the SFT. The initiative will supplement Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) due to its “focus on how substances are marketed and used in real life.”

The process is not completely mandatory. According to the Board, “a legal commitment to declare a product arises only if a significant risk has been identified. . . . [f]ew nanomaterials will qualify under this criterion in the short term.”  The Board advocates a mandatory scheme as soon as it is feasible, and urges industry “to embrace the initiative right away.”

UN Committee Will Discuss Ongoing Work on the Safety of Nanomaterials

During the June 29-July 1, 2009, meeting of the United Nations (UN) Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labeling of Substances (GHS), the Committee will discuss a paper entitled “Ongoing Work on the Safety of Nanomaterials.” The paper provides a summary of current activities by the European Union (EU), including the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) program, International Organization for Standardization (ISO), and the Organization for Economic Cooperation and Development (OECD). The paper includes the following questions:

  • Can it be considered, for the same chemical (same [Chemical Abstracts Service (CAS) Number] and purity) that nanomaterials with new properties have the same hazards as conventional form?
  • Is it possible to distinguish for a same chemical, the properties of its different nanoforms?
  • How can this be done? Should new endpoints be determined?
  • To which extent information about nanomaterials need be provided?
  • What kind of information is needed?
  • What kind of communication tool is needed for this purpose?
  • What kind of collaboration can be suggested in order to contribute to clarification of nanomaterials hazard classification and indeed to heath safety and environmental issues of nanomaterials?

 

European Parliament Urges the Labeling of Nanomaterials in Consumer Products

In an April 24, 2009, press release, the European Parliament (EP) calls for the provision of information to consumers on the use of nanomaterials in consumer products. According to the EP, all ingredients present in the form of nanomaterials in substances, mixtures, or articles should be clearly indicated in the product labeling. The press release also specifically calls for the European Commission (EC) to evaluate the need to review the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) concerning:

  • Simplified registration for nanomaterials manufactured or imported below one tonne;
  • Consideration of all nanomaterials as new substances;
  • A chemical safety report with exposure assessment for all registered nanomaterials; and
  • Notification requirements for all nanomaterials placed on the market on their own, in preparations, or in articles.

The EP also calls for the EC to evaluate the need to review worker protection legislation concerning:

  • The use of nanomaterials only in closed systems or in other ways that exclude exposure of workers as long as it is not possible to detect reliably and control exposure;
  • A clear assignment of liability to producers and employers arising from the use of nanomaterials; and
  • Whether all exposure routes (inhalation, dermal, and other) are addressed.
