- EC10 or NOEC for freshwater algae:
- 1 mg/L
Additional information
Algae growth inhibition of the test item was investigated in a 72-h GLP study following OECD TG 201. Due to the low water solubility, the test concentrations were prepared as water accomodated fractions (WAF) as described in OECD TG 23. The test concentrations could not be chemically verified due to the lack of a sufficiently sensitive method to determine the test substance in the test solutions up to its saturation limit. Therefore, the results are based on loading rate ("nominal concentrations"). However, the stability of the test item over a period of 96 hours was verified in a separate study. Details are given in the robust study summary of the key study itself.
Based on growth rate, the 72-h NOELR was 1 mg/L and the ErL50 was 12.3 mg/L (BASF, 2011).
In conclusion, the substance is acutely harmful to algae.
