Description of key information

Key study: K_Simon_2006: EC10 = 9.3 mg/L; EC50 = 33 mg/L (respiration rate)

Key value for chemical safety assessment

EC50 for microorganisms:
33 mg/L
EC10 or NOEC for microorganisms:
9.3 mg/L

Additional information

The toxicity test to microorganisms (Simon_2006) performed according to OECD 209 and GLP was rated with RL=1 (reliable without restrictions) and used as key study. The results indicate that there is significant inhibition of bacterial respiration by SymWhite 377 starting at a concentration of 7.8 mg/L. For the respiration rate the EC10 and EC50 value are 9.3 mg/L and 33 mg/L.
