Substances of Very High Concern?

Substances of Very High Concern?

Author: ChemistryViews

New proposals to identify an additional thirteen chemicals as Substances of Very High Concern (SVHCs) have been published by the European Chemicals Agency (ECHA). Interested parties are invited to join the public consultation by posting their comments on the ECHA website by using the dedicated webform till 12 April 2012.

Comments should provide information concerning the identity of the substances listed below and described in detail on the ECHA website. The Member State Committee will take these comments into account when seeking agreement on the identification of a proposed substance as an SVHC.
Information on the uses of the substances is also invited. This would include data on tonnages per use and exposures or releases resulting from these uses. Information on the availability of safer alternative substances and techniques, and the structure of supply chains is also welcome.

As yet, 73 SVHCs have been included in the Candidate List. Inclusion on the list imposes new information requirements on suppliers of preparations and articles containing the substances.
The proposals have been put forward by Belgium with Poland, the Netherlands, Germany, and ECHA, at the request of the European Commission.

Table. Substances proposed for identification as an SVHC, reasons for their proposal, and their potential uses according to information provided in the Annex XV dossiers submitted for the substances.
