Description of key information
This summary provides a brief overview of the endpoints in the context of aquatic toxicity which are data requirements according to Reach, Annex XVIII:
Short-term toxicity to aquatic invertebrates (WoE)
The EC50 values obtained from several independent experimental studies are in the same order of magnitude. The most conservative value of 1.6 mg/L is chosen as key value for assessment.
Toxicity to aquatic algae and cyanobacteria (WoE)
The reported 96h-EC50 values are in the range of 2.9 mg/l to 10 mg/l. Based on the availabilty and reliabilty of data and following the most conservative approch the EC50 value of 2.9 mg/L was chosen for assessment.
