Description of key information

Key value for chemical safety assessment

Additional information

The activated sludge respiration inhibition test was waived, because a biodegradation study according to OECD 301 B and in compliance with GLP that included a toxicity control was available. Nonane-1,9-diol was observed to have no inhibitory effects on microorganisms up to a concentration of 20 mg/L TOC (% degradation: 93.3% after 14 days).
