Endpoint summary

Description of key information

Study reports have been available for acute tests with fish, invertebrates, algae and micro-organism. The results are summarized as below:

Fish acute toxicity test with Zebra fish: Based on the key study result according to OECD TG 203 (GLP), LC50-96 h was determined to be above 100 mg/L. 

Daphnia acute toxicity test: Based on the key study result according to OECD TG 202 (GLP), the EC50-48 h was determined to be above 100 mg/L.

Alga growth inhibition test: Based on the key study result according to OECD TG 201 (GLP), the 72 h EC50 value was 43 mg/L based on the growth rate with the 95 % confidence limit of 26-86 mg/L. The NOEC for yield and growth rate were 1.0 mg/L in this study.

Microorganism respiration inhibition test: Based on the key study result according to OECD TG 209 (GLP), the EC50 of the test substance was above 1000 mg/L. The NOEC therefore is 1000 mg/L.
