- Executive summary:
The acute toxicity potential on fish was investigated following the procedures outlined into the OECD guideline 203.
First, a range-finding experiment was performed at the concentrations of 1, 10 and 100 mg/l. No deaths occurred, thus 100 mg/l was chosed as concentration for the main study. Also in this case no death was recorded.
Conclusion
LC50 (96h) > 100 mg/l (nominal)

Description of key information
LC50 (96h) > 100 mg/l (nominal)
Key value for chemical safety assessment
Additional information
The acute toxicity potential on fish was investigated following the procedures outlined into the OECD guideline 203.
First, a range-finding experiment was performed at the concentrations of 1, 10 and 100 mg/l. No deaths occurred, thus 100 mg/l was chosed as concentration for the main study. Also in this case no death was recorded.
Although concentrations during the test were not measured, the substance is expected to be stable over the experiment period. Acid Red 057 is water soluble; it is not readily biodegradable and, based on the chemical structure, it is not expected to undergo hydrolysis.
