Tris(2,4-di-tert-butylphenyl)phosphite is with high probability acutely not harmful to fish.

Key value for chemical safety assessment

Additional information

A static limit test performed according to the OECD guideline 203 using a water-accommodated fraction approach [Ciba, 2002]. The nominal test concentration was 100 mg/L. Analysis of the test solution showed that the concentration was below the analytical detection limit of 100 µg/L. No mortalities or other abnormalities were seen in fish exposed to the test solution for 96 hours. Hence, the 96-hour LC0 was determined to be higher than the loading rate of at least 100 mg/L.
