Description of key information
Toxicity
Hazardous to the aquatic environment, short-term (acute): Very toxic to aquatic organisms.
Hazardous to the aquatic environment, long-term (chronic): Very toxic to aquatic life with long lasting effects.
LC50 - Fish: 13.23 mg/l
EC50 - Crustaceans: 9.89 ml/l Daphnia magna
EC50 72h - Algae: 0.82 mg/l Pseudokirchneriella subcapitata (biomass)
EC50 72h - Algae: 5.59 mg/l Pseudokirchneriella subcapitata (growth rate)
NOEC Chronic fish: 7 mg/l 96 hours
NOEC Crustacean chronic: < 0.5 mg/l 48 hours
NOEC Chronic algae: < 0.3 mg/l Pseudokirchneriella subcapitata (biomass and growth rate)
Persistence and degradability
Persistence and degradability: In accordance with Regulation (EC) No. 1272/2008, if no useful data on degradability are available, the substance should be considered not rapidly degradable.
Biodegradation: Degradation in aquatic environment equal to 0.3% after 28 days.
Bioaccumulative potential
Partition coefficient n-octanol/water (Log Pow): 4.46 (estimated).
Bioaccumulative potential: Based on the Log Pow value of 4.46, a high bioaccumulation potential is expected.
Additional information
The substance is classified as very toxic to aquatic life (CLP Regulation - category 1)
The substance is classified as very toxic to aquatic life with long lasting effects (CLP Regulation - category 1)
