Key value for chemical safety assessment
- EC50 for microorganisms:
- 16 mg/L
Additional information
EC50 Vibrio fisheri at 30 min of 0.031 mg/l in freshwater in Hernando et al (2006) study is the most conservative result. Nevertheless, the DyStarColours Distribution GmbH (1998) study is more contextual data for the evaluation of the end point. The test performed on Vibrio fischeri is not designed properly to investigate the microorganisms toxicity in general.
In order to estimate the STP PNEC, data from studies investigating the effects of a substance on micro-organisms from activated sludge of waste-water treatment plants are suitable and more appropriate because assess effects on a spectrum of different microorganisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
