Description of key information
Fatty acids, C8-10, zinc salts:
Toxicity studies of fatty acids, C8-10, zinc salts are not available. In the assessment of environmental toxicity of fatty acids, C8-10, zinc salts, read-across to the assessment entities zinc and C8 -10 fatty acids is applied since zinc cations and fatty acid anions determine its fate and toxicity in the environment. Please refer to the respective assessment entity for further details.
C8-10 fatty acids:
In a reliable, GLP-conform chronic toxicity test with Daphnia magna according to OECD 211, a 21 d NOEC of 0.2 mg/L was determined for the effect of decanoic acid (C10) on the reproduction of Daphnia magna.
Zinc:
Freshwater: Data on 13 species available. Species NOECs range between 0.014 and 0.400 mg Zn/l (dissolved concentrations)
Marine: Data on 26 species available. Species NOECs range between 0.0056 and 0.9 mg Zn/l (dissolved concentrations)
Respective NOEC/EC10 values were applied in the species sensitivity distribution.
Key value for chemical safety assessment
