Description of key information
One reliable (Klimisch 1) toxicity study for microorganisms was available for Behenyl Bottoms. The toxicity of Behenyl Bottoms to activated sludge was reported by Schaefer & Twilly (2009) in an OECD 209 guideline and GLP compliant study. Activated sludge was exposed nominal concentrations of the test substance for 3 hours, resulting in a 3-hr LC50 of >1,000 mg/L, based respiration rate.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
Additional information
The toxicity of Behenyl Bottoms, characterized asC18-22, distillation residues, to microorganisms has been evaluated for this dossier. One reliable (Klimisch 1) toxicity study for microorganisms was available for Behenyl Bottoms. The toxicity of Behenyl Bottoms to activated sludgewas reported by Schaefer & Twilly (2009) in an OECD 209 guideline and GLP compliant study. Activated sludge was exposed nominal concentrations of the test substance for 3 hours, resulting in a 3-hr LC50 of >1,000 mg/L, based respiration rate. This reliable study result is designated as Key for the toxicity to microorganisms endpoint.
