Description of key information

CIT report (2009) was selected as key study, since conducted according to OECD guideline and GLP.
The algae Pseudokirchneriella supcapitata was exposed to vanillin in a 72-hour static test.
The 72 -hour ErC50 (geometric mean) was 120 mg/L.
The 72 -hour EyC50 (geometric mean) was 78.6 mg/L
The NOEC was 47 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
120 mg/L
EC10 or NOEC for freshwater algae:
47 mg/L

Additional information

Only one study (CIT, 2009) was selected as key study, because it was conducted according to OECD guideline and GLP.

In this study, Vanilline is considered to be harmful to algae.
