Description of key information
ZINN(II)-RICINOLEAT was not toxic to waste water (activated sludge) bacteria at a concentration of 100 mg/L in a study conducted according to OECD guideline 209.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
Additional information
The influence on the respiration rate of activated sludge was investigated after a contact time of 30 minutes in a study conducted according to OECD guideline 209. Since ZINN(II)-RICINOLEAT was known to be poorly soluble in water the substance was added directly to the test media.
No significant inhibition in respiration rate of the sludge was recorded at exposure to a nominal concentration of 100 mg/L ZINN(II)-RICINOLEAT.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
