Description of key information

In the OECD guildeline (201) study Selenastrum sp. were exposed to 5 nominal concentrations of 100 - 1000 mg/l TMP for 72h. The EC50 (72h) and NOEC are >= 1000 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
1 000 mg/L
