Description of key information
Additional information
Three key studies are available for short-term aquatic toxicity for three trophic levels. In addition, two key studies for chronic aquatic toxicity are also available for aquatic invertebrates and algae.
Short-term toxicity to fish:
- LC50 (96h) = 74.8 mg/L (OECD Guideline 203) (reliability Klimisch 1a)
Based on the results of this study, n-heptanoic acid is considered as harmful to fish.
Short-term toxicity to aquatic invertebrates:
- EC50 (48h) = 72 mg/L (OECD Guideline 202) (reliability Klimisch 1a).
Based on the results of this study, heptanoic acid is considered as harmful to daphnia.
Short-term toxicity to algae:
- EC50 (72h) = 61.2 mg/L (OECD Guideline 201) (reliability Klimisch 1a).
Based on the results of this study, heptanoic acid is considered as harmful to algae.
Long term toxicity to invertebrates
- NOEC = 20 mg/L (OECD 211 guidelines) (reliability Klimisch 1a)
Long term toxicity to algae
- NOEC = 46 mg/L (OECD Guideline 201) (reliability Klimisch 1a).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
