Further public consultation on the carcinogenicity of gallium arsenide
Media enquiries: ECHA Press
Following a request from the European Commission for a supplementary scientific opinion, ECHA asks concerned parties to submit information and comments on the carcinogenicity of gallium arsenide and its metabolites, as well as on the read-across approach described in the opinion of the Committee for Risk Assessment of 25 May 2010.
Helsinki, 11 March 2011 - Interested parties are invited to provide, by 25 April 2011, any relevant new information on gallium arsenide and its metabolic products, including the read-across approach which was described in the 25 May 2010 opinion of the Committee for Risk Assessment (RAC).
The Committee will examine the information and comments received during the public consultation and adopt an updated opinion, as necessary. The opinions and the possible updated opinion of RAC will be forwarded to the European Commission.
In 2009, France submitted a proposal for the harmonised classification of gallium arsenide as a carcinogen category 2. A public consultation on the proposal was held in June/July 2009. After the public consultation, ECHA's Committee for Risk Assessment (RAC) adopted on 25 May 2010 a scientific opinion recommending that gallium arsenide should be classified EU-wide as a carcinogen in category 1A. For its opinion, RAC considered also a recently published IARC analysis which was not available to the Committee prior to the consultation process. The new IARC analysis supported RAC´s view on higher carcinogenity of gallium arsenide.
Due to the fact that new information became available after the first public consultation was launched, the European Commission had asked ECHA to organise a second public consultation to ensure that all relevant new data can be considered by the Commission in taking its decision.
ECHA is now calling for relevant new studies or information on the carcinogenicity of gallium arsenide or its metabolic products which were not available to RAC for its first opinion and are not on the list of documents in RAC´s opinion of 25 May 2010. ECHA also asks for relevant comments on the read-across approach described in the same opinion.
After the public consultation which starts today and ends on 25 April 2011, RAC will review the information and comments received and, if the Committee deems it necessary, will update its opinion. After this, the European Commission will proceed with the decision on the harmonised classification and labelling of gallium arsenide.
The role of RAC in EU regulatory processes
RAC is responsible for preparing scientific opinions of the Agency on proposals for harmonised classification and labelling and other questions relating to risks to human health or the environment. The final decision for harmonised classification and labelling will be taken by the European Commission through a committee procedure.
Upon specific requests from the Executive Director of ECHA, the Committee is responsible for drawing up opinions relating to risks to human health or the environment and on any other aspects concerning the safety of substances on their own, in preparations or in articles (Article 77(3) (c) of REACH).
Public Consultations on Harmonised Classification & Labelling (CLH)
ECHA invites concerned parties to comment on proposals for harmonised classification and labelling that were submitted by Member State Competent Authorities, manufacturers, importers or downstream users. ECHA can also call for comments on other aspects that are relevant to the harmonisation of the classification and labelling of a substance.
