Description of key information

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

Key value for chemical safety assessment

Additional information

The toxicity of tris(2,4-di-tert-butylphenyl)phosphite on the green algae Scenedesmus subspicatus was measured in a test performed according to the OECD guideline 201 [Ciba, 1992]. Tween 80 was used as solubiliser. The test concentrations was analytically monitored. No effect observed up to the highest test concentration of about 75.2 mg/L.
