Endpoint summary

Description of key information

Short-term toxicity to fish

The LC50 was above 100 mg/L after 96 hours. The substance is not considered to pose a hazard to fish.

Short-term toxicity to aquatic invertebrates

Under the conditions of the test the EC50 > 100 mg/L. The substance is not considered to pose a hazard to Daphnia magna.

Toxicity to aquatic plants and cyanobacteria

The results of the original study have been reviewed, and it has been determined that the EC50 values are > 100 mg/L.

Toxicity to microorganisms

The EC10 and EC50 of the substance to activated sludge (domestic sewage treatment plant) is higher than 1000 mg/L (nominal), which was the highest concentration in the test.
