Endpoint summary
Administrative data
Description of key information
Short-term toxicity to fish: LC50 (96 h) > 100 mg/l
Short-term toxicity to invertebrates: EC50 (48 h) = 1.03 mg/l
Toxicity to algae and cyanobacteria: IC50 (72 h) = 3.4 mg/l of active material
Additional information
Information regarding aquatic toxicity is available for three different trophic levels by testing the following species: Brachydanio rerio (fish); Daphnia magna (crustacea), Pseudokirchneriella subcapita (algae).
Freshwater fish assessment
The substance has been tested for
short-term toxicity testing on fish according to the guideline OECD 203
(1992).
The
organisms have been subjected to the test item at test concentrations of
1 mg/l, 3.21 mg/l, 10 mg /l, 32.1 mg/l and 100.4 mg/l for 96 hours.
The LC50 (96 h) was determined to be higher than 100 mg/l.
Freshwater Crustacea assessment
The substance has been tested for short-term toxicity on freshwater invertebrates according to the guideline OECD 202 (1984). The organisms have been exposued to the test item at concentrations of 0.1 mg/l, 1 mg/l, 10 mg/l, 100 mg/l and 1000 mg/l for 48 hours.
The EC50 (48 h) was determined to be 1.03 mg/l.
Freshwater Alga and Cyanobacteria assessment
The substance has been tested for acute toxicity on algae according to the OECD guideline 201 (1984). The alga has been subjected to the substance at the test concentrations of 0.1 mg/l, 0.32 mg/l, 1 mg/l, 3.2 mg/l, 10 mg /l, 32mg/l and 90mg/l for 72 hours.
The IC50 (72 h) was determined to be 3.4 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
