Description of key information

Additional information

Available studies on fish, algae and microorganisms did not reveal any toxic effect in the range of water solubility of the compound. The study on daphnia is not regarded as valid due to the limited exposure time of only 24 h instead of 48 h. Furthermore, undissolved parts of the test compound could be detected. Due to the low water solubility of the test substance a long-term toxicity study on daphnia was conducted to adequately assess the toxicity towards aquatic invertebrates. No adverse effect was observed up to the highest loading rate (10mg/L).

Short-term toxicity to fish:

There is a high probability that the product is not acutely harmful to fish. No toxic effects occur in the range of water solubility.

Long-term toxicity to aquatic invertebrates:

Based on long-term (chronic) toxicity study data, the product is very likely not harmful to aquatic invertebrates. No toxic effects occur in the range of water solubility.

Toxicity to aquatic algae and cyanobacteria:

There is a high probability that the product is not acutely harmful to aquatic algae. No toxic effects occur in the range of water solubility.

Toxicity to microorganisms:

The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
