Description of key information
Additional information
The test substance has shown to be harmful to algae, daphnids and microorganisms, but showed no toxicity to fish.
The key study for fish reported an LC50(96h)>100 mg/L, a supporting study yielded a value of 346 mg/L. Effects to algae were reported with EC50(72h) values >75.7 mg/L, effects on microorganisms (Pseudomonas putida, 16.7h) with 40.4 mg/L. Slightly more sensitive organisms were daphnids with effects on immobilisation (EC50(48h)) at 24.3 mg/L.
The only experimental NOEC was reported for the algae study with a 72-h value of 9.4 mg/L. Daphnids exhibited a higher sensitivity towards the test substance in acute testing, however the results of the acute tests with algae and daphnids were in the same range (10-100 mg/L).
The EC10(16.7h) for Pseudomonas putida was reported at 24.4 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
