Endpoint summary

Administrative data

Description of key information

Short-term toxicity to aquatic invertebrates (daphnia)

EC 50 (48 h)= 0.17 ppm (measured)

Toxicity to aquatic algae and cyanobacteria (algae)

ErC50 (72 h) > 0.01 mg/l (calculated from the raw data)

Additional information

Justification for classification or non-classification

Classification for acute aquatic toxicity is based on the following acute data:

EC 50 (48 h) Daphnia = 0.17 ppm (measured)

ErC50 (72 h) Algae > 0.01 mg/l (= 0.03 mg/l)

Based on the aquatic toxicity data the classification for Acute Category 1 (H400) is suggested.

For classification for chronic aquatic toxicity adequate chronic data for the 3 throphic levels is not available, therefore the main assessment is performed based on acute aquatic toxicity data and environmental fate data (biodegradation), according to CLP, Annex I, fig. 4.1.1, and table 4.1.0 (b)(iii). An EC50 < 1 mg/l for both daphnia and algae are obtained and the substance is non-readily biodegradable. Therefore, the classification for Chronic Category 1 (H410) is proposed.

An M-factor of 10 applies for acute toxicity and chronic toxicity.
