Description of key information
Supporting study: Test method ASTM guideline. No GLP. The 7 days-EC50/EC10 was determined to be > 1000 µg/L (based on frond number, wet weight, chlorophylls a and be, and carotenoids).
Key value for chemical safety assessment
- EC50 for freshwater plants:
- 1 mg/L
- EC10 or NOEC for freshwater plants:
- 1 mg/L
Additional information
The influence of amoxicillin on the growth of a freshwater plant was studied by Brain et al. (2008) according to the ASTM guideline. Lemna gibba was exposed up to 1000 μg/L test item in triplicate for 7 days under static-renewal conditions. The 7 days-EC50/EC10 was determined to be higher than 1000 μg mg/L based on frond number, wet weight, chlorophylls a and b, and carotenoids.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
