Description of key information
Exposure considerations according to REACH Annex XI No. 3, as well as REACH Annex IX (9.1.5) column 2. -
In accordance with REACH Annex XI No. 3 and Annex IX (9.1.5) column 2, the long term aquatic invertebrates study does not need to be conducted as the results of the exposure calculations in the Chemical Safety Assessment do not indicate a relevant exposure to the aquatic environment. Therefore, no need for further testing can be identified.
Key value for chemical safety assessment
Additional information
The algae is the most sensitive aquatic species which shows a 72h-EC50 = 70 mg/L. This value does not lead to the requirement to classify the substance for acute aquatic toxicity. Also the chronic algae value 72h-(96h)-EC10 (=NOEC) = 3.2 mg/L (nominal) does not lead to the requirement to classify the substance for chronic aquatic toxicity, even when taken into account the poor biodegradability of the substance according to 2nd ATP.
