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 VII (Article 18, above 1000t):


Short-term toxicity to aquatic invertebrates (WoE)


The EC50 and LC50 values obtained from these studies are in a similar order of magnitude.


48h-EC50: 7.4 mg/l - 28.1 mg/L
48h-LC50: 7.5 mg/l - 17.6 mg/L
24h-EC50: 20.8 - 24 mg/L
24h-LC50: 35 mg/l


The most conservative 48h-LC50 value of 7.5 mg/L  (Deneer 1989, Maas-Diepeveen 1986) is chosen as key value for assessment.


 


Toxicity to aquatic algae and cyanobacteria (WoE)


The EC50/TT/EC3/IC50 values obtained from various experimental studies are in a similar order of magnitude.


The 96h-EC50 value of 14 mg/L reported independently by Maas-Diepeveen 1986 and Deneer 1988/1989 was chosen as key value for chemical safety assessment. This value is supported by other studies (TT/EC3/IC50-values in the range of: 1-52 mg/l).
