Description of key information

ErC50 (72 h) > 940 mg/L for Selenastrum capricornutum (OECD 201)
NOEC (72 h) 468 mg/L for Selenastrum capricornutum (OECD 201)

Key value for chemical safety assessment

Additional information

One experimental study investigating the toxicity of triacetin (CAS 102-76-1) to freshwater algae is available (Toray Research Center, 1998). The study was conducted according to OECD 201 under GLP conditions using the freshwater algae Selenastrum capricornutum. Five concentrations up to a maximum of 1000 mg/L (nominal) were tested in a static exposure regime. The test substance concentrations were determined analytically by GC/FID. A NOEC (72 h) of 468 mg/L and an EC50 (72 h) of > 940 mg/L based on the measured (geom. mean) concentrations based on the growth rate resulted.
