Description of key information
Short-term toxicity to fish
The test item was investigated for its toxicity to fish in two acute studies according to OECD guideline no. 203. The first study was conducted as semi-static test on zebra fish (Brachydanio rerio) over 96 hours and showed a LC50 of 3.2 mg/l. The second study was also performed on semi-static conditions over 96 hours and the species used was Gobiocypris rarus. The LC50 value determined in this study was 1.74 mg/l.
In conclusion, the test item needs to be classified as acute toxic to fish.
Short-term toxicity to aquatic invertebrates
The test item was investigated for its toxicity to aquatic invertebrates in an acute study according to OECD guideline no. 202. The study was conducted as semi-static test on Daphnia Magna over 48 hours and showed a EC50 of 3.2 mg/l. In conclusion, the test item needs to be classified as acute toxic to aquatic invertebrates.
Toxicity to aquatic algae and cyanobacteria
The test item was investigated for its toxicity to green algae in a study according to OECD guideline no. 201. The study was conducted as static test on Pseudokirchneriella subcapitata over 72 hours and showed a EbC50 of 0.46 mg/l. In conclusion, the test item needs to be classified as very toxic to Green algae.
Toxicity to microorganisms
The test item was investigated for its respiration inhibition on activated sludge over 3 hours in accordance with OECD-method no. 209. The substance showed an inhbitory effect on waste water bacteria resulting in an EC50 of 37 mg/l. The EC20 was calculated to be 6.9 mg/l.
