Description of key information

Assessment of Algal toxicity using ECOSAR.

Key value for chemical safety assessment

EC50 for freshwater algae:
19.798 mg/L

Additional information

Regulation (EC) No 2037/2000 of the European Parliament And Of The Council of 29 June 2000 on substances that deplete the ozone layer lists within ANNEX I states that the substance is listed as a Group 1 substance. However, the registrant has a derogation in accordance with Regulation (EC) No 1005/2009 of the European Parliament and of the Council of 16 September 2009 on substances that deplete the ozone layer that allows for use of the substance as a processing agent. 

However, in accordance with the above two pieces of legislation, release is strictly controlled. As such, no release to the aquatic environment is envisaged, and hence it is deemed inappropriate to assess this endpoint on the basis of no-release. Instead, an assessment utilising ECOSAR v1.00 is proposed. The results of this give a 96-hr LC50 of 19.798 mg/l. On the basis of this, it is proposed that the substance could potentially be hazardous to Algae


The risk phrase: H412: Harmful to aquatic life with long lasting effects is applicable.
