Description of key information

No effects on hatching, mortality, weight, and length was seen in danio rerio in a fish early life stage test (FELS) according to OECD 210 and thus the NOEC in this study is ≥ 60 mg/L (highest concentration tested).

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
60 mg/L

Additional information

The toxicity of the test item sulfamic acid in the Early-Life Stage Toxicity Test against Danio rerio was tested under flow-through conditions. One valid experiment was performed using five concentrations ranging from 5.6 mg/L to 60 mg/L test item.

As no concentration tested showed any toxic effect, only the highest concentrated treatment 60 mg/L was necessary for evaluation of the results. The measured concentrations in this treatment lay in a range from 88 % to 96 % of the nominal concentration. Therefore, the determination of the results was based on the nominal concentrations

The following results for the test item sulfamic acid could be determined:

 

Endpoint

NOEC

LOEC

Hatching

≥ 60 mg/L
