The fish were observed for survival and toxic signs (changes in appearance, swimming behaviour and behaviour in comparison to the control group) within 1 hour after start of exposure and 4, 24, 48, 72 and 96 hours after start of exposure. Fish were considered dead if there was no visible movement and no reaction after touching. Dead fish were removed from the test vessels.

- Executive summary:
The toxicity of Nonane-1,9-diol to Danio rerio was determined in a reliable limit test according to OECD 203 and in compliance with GLP. Individuals of D. rerio were exposed to the substance in a concentration of 100 mg/L, equivalent to 84.8 mg/L mean measured concentration for 96 hours. The concentration was analytically verified via GC-FID. No mortality and no abnormal behaviour were observed within the 96 hours. The effect values LC50 and NOEC were both determined as > 100 mg/L of Nonane-1,9-diol based on nominal concentrations.
