Description of key information

NOEC = 8 mg/L; EC50 and EC10 (16 h) > 8 mg/L (CAS 28777-98-2)

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
8 mg/L

Additional information

Because no test with 2,5-Furandione, dihydro-, mono-C15-20-alkenyl derivs on acute toxicity in fish is available, a test with the main constituent C18 ASA is assessed.

In a limit test performed in accordance with ISO 10712, no effect on the growth of Pseudomonas putida strain NCIB 8248 has been noted after exposure for 16 hto the nominal concentration of 8 mg/L in DMSO. Thus, the NOEC was 8 mg/L and the EC50 > 8.0 mg/L, respectively.

Since the tested substance C18 ASA is a main constituent of 2,5-Furandione, dihydro-, mono-C15-20-alkenyl derivs, the same outcome of the tests would be expected for 2,5-Furandione, dihydro-, mono-C15-20-alkenyl derivs.
