Endpoint summary

Description of key information

Short-term toxicity to fish

Based on the results of an acute toxicity to fish study, the test item had no toxic effect at the limit concentration of 100 mg/L on Zebrafish. Accordingly, the 96-h LC50 value was determined to be > 100 mg/L. The 96-h NOEC was determined to be 100 mg/L.

 

Short-term toxicity to aquatic invertebrates

In a 48-hour acute toxicity test with Daphnia magna the 48 h EC50 value was determined to be 45.1 mg/L.

 

Toxicity to aquatic algae and cyanobacteria

The 72-h EC50 value based on growth rate and yield were determined to be 1.56 mg/L and 0.67 mg/L, respectively. The 72-h EC10 value based on growth rate and yield were determined to be 0.49 mg/L and 0.26 mg/L, respectively. The 72-h NOEC related to growth rate and yield was determined to be 0.29 mg/L.

 

Toxicity to microorganisms

Aim of the 3 hour test was to evaluate the influence of the test item on the acitivity of the activated sludge fed with synthetic sewage. The EC10 value was 125.8 mg/L after 3 hours. The EC50 and EC80 values were determined as > 1000 mg/L.
